We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

You may find it useful to use as a template. dhcp_probe_notify2 is a sample alert program, suitable for specification via the alert_program_name2 configuration file statement. It is a Perl script that sends email. If you choose to use, it, install it someplace on your system where the dhcp_probe daemon can execute it. You will need to edit the definitions at the top of this script. Note that it calls the mail-throttled script below. dhcp_probe_notify is a sample alert program, similar to dhcp_probe_notify2; see the description above for 'dhcp_probe_notify2' for details. Unlike dhcp_probe_notify2, this program supports the older syntax used by the alert_program_name configuration file statement, rather than the newer syntax used by the alert_program_name2 configuration file statement. Because the older syntax is not extensible, this version cannot provide all the same features as 'dhcp_probe_notify2'. mail-throttled is a perl script called by dhcp_probe_notify2 or dhcp_probe_notify to throttle the frequency of messages that share a unique "key" specified by its caller. If you choose to use, it, install it someplace on your system where the dhcp_probe_notify script (called by dhcp_probe daemon) can execute it. You will need to edit the definitions at the top. dhcp_probe.startup.Solaris9 is a sample startup script that works in Solaris 9. If you choose to use it, place it in /etc/init.d/ with the filename 'dhcp_probe', and the symlinks documented in the script's comments. dhcp_probe.FreeBSD.sh is a sample rcNG script for use with FreeBSD. If you choose to use it, place it in /usr/local/etc/rc.d/ with the filename 'dhcp_probe.sh', then enable it in /etc/rc.conf: dhcp_probe_enable="YES" dhcp_probe_flags="" dhcp_probe.xml is a sample SMF manifest file and site-application-dhcp_probe is a sample Solaris method script, for use with Solaris SMF. If you choose to use them, place site-application-dhcp_probe in /lib/svc/method/site-application-dhcp_probe (for example), and place dhcp_probe.xml in /var/svc/manifest/site/application/dhcp_probe.xml (for example). Edit dhcp_probe.xml to specify an instance for each network interface on which you wish to run the program, naming each instance the same as the network interface name. Edit site-application-dhcp_probe as necessary. Then import the manifest and enable each desired instance, for example: /usr/sbin/svccfg -v validate /var/svc/manifest/site/application/dhcp_probe.xml /usr/sbin/svccfg -v import /var/svc/manifest/site/application/dhcp_probe.xml svcadm enable svc:/site/application/dhcp_probe:INSTANCE1 svcadm enable svc:/site/application/dhcp_probe:INSTANCE2 svcadm enable svc:/site/application/dhcp_probe:INSTANCE3 etc. rotate_logs is a log rotation utility which may optionally be used by site-application-dhcp_probe to rotate packet capture files. dhcp_probe-1.3.1/m4/ac_check_func_proto.m4000064400000000000001000000027601011265534600205620ustar00rootother00004560370030dnl ################################################################## dnl The macro AC_CHECK_FUNC_PROTO dnl comes from aclocal.m4 in the sample code associated dnl with "UNIX Network Programming: Volume 1", Second Edition, dnl by W.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

[This is the first released version of the library GPL. It is numbered 2 because it goes with version 2 of the ordinary GPL.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Library General Public License, applies to some specially designated Free Software Foundation software, and to any other libraries whose authors decide to use it. You can use it for your libraries, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library, or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link a program with the library, you must provide complete object files to the recipients so that they can relink them with the library, after making changes to the library and recompiling it. And you must show them these terms so they know their rights. Our method of protecting your rights has two steps: (1) copyright the library, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the library. Also, for each distributor's protection, we want to make certain that everyone understands that there is no warranty for this free library. If the library is modified by someone else and passed on, we want its recipients to know that what they have is not the original version, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that companies distributing free software will individually obtain patent licenses, thus in effect transforming the program into proprietary software. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License, which was designed for utility programs. This license, the GNU Library General Public License, applies to certain designated libraries. This license is quite different from the ordinary one; be sure to read it in full, and don't assume that anything in it is the same as in the ordinary license. The reason we have a separate public license for some libraries is that they blur the distinction we usually make between modifying or adding to a program and simply using it. Linking a program with a library, without changing the library, is in some sense simply using the library, and is analogous to running a utility program or application program. However, in a textual and legal sense, the linked executable is a combined work, a derivative of the original library, and the ordinary General Public License treats it as such. Because of this blurred distinction, using the ordinary General Public License for libraries did not effectively promote software sharing, because most developers did not use the libraries. We concluded that weaker conditions might promote sharing better. However, unrestricted linking of non-free programs would deprive the users of those programs of all benefit from the free status of the libraries themselves. This Library General Public License is intended to permit developers of non-free programs to use free libraries, while preserving your freedom as a user of such programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as regards changes in header files, but we have achieved it as regards changes in the actual functions of the Library.) The hope is that this will lead to faster development of free libraries. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, while the latter only works together with the library. Note that it is possible for a library to be covered by the ordinary General Public License rather than by this special one. GNU LIBRARY GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Library General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also compile or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. c) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. d) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Library General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Library General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Library General Public License for more details. You should have received a copy of the GNU Library General Public License along with this library; if not, write to the Free Software Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

Add reference to libnet patch to libnet_cq_destroy(). Sun Nov 17 14:31:48 EST 2013 Irwin Tillman (irwin at princeton dot edu) * src/configfile.c: remove '/*' inside comment. Sun Nov 17 14:26:10 EST 2013 Ilkka Virta * src/dhcp_probe.c, src/dhcp_probe.h: wrap pcap_dispatch() call in a loop with our own own timeout around it. This allows the specified response_wait_time to be respected even on platforms where the read timeout passed to pcap_open_live() is not supported. Sun Nov 10 13:13:31 EST 2013 Ilkka Virta * src/dhcp_probe.c: call pcap_breakloop() in signal catching when handling SIGINT, SIGTERM, SIGQUIT. Failing to call that allowed pcap_dispatch() to sleep indefinitely while awaiting a response from a DHCP server. Sun Nov 10 13:01:11 EST 2013 Irwin Tillman (irwin at princeton dot edu) * configure.ac: check for declaration and definition of pcap_breakloop. * INSTALL.dhcp_probe: specify that version 0.8.1 or later of libpcap is needed. Sat Nov 9 16:41:45 EST 2013 Laurent Guignard * doc/dhcp_probe.8: fix spelling error. Sun Sep 29 17:42:09 EDT 2013 Irwin Tillman (irwin at princeton dot edu) * src/defs.h: define (if not already defined) ETHERTYPE_IP, ETHERTYPE_VLAN * src/dhcp_probe.h: define MAX_ETHER_TYPE_STR * src/dhcp.c: change bpf filter to also accept frames with a vlan tag. Accept frames with VLAN tag where VLAN ID == 0. * doc/dhcp_probe.8: document that we accept frames with VLAN tag where VLAN ID == 0. Clarify use of -Q option. * doc/dhcp_probe.8: updated LIMITATIONS to note that Ethernet switches which selectively filter (rather than flood) layer 2 broadcasts sent by DHCP/BootP clients will prevent the program from locating DHCP and BootP servers. * PLATFORMS: added libpcap 1.3.0, 1.4.0. Removed Solaris 9 from platforms the author presently develops on. Sat Sep 21 16:35:43 EDT 2013 Irwin Tillman (irwin at princeton dot edu) * Upgrade automake 1.12.6 to 1.13.4. * configure.ac: quote more arguments. Stop passing arguments to AC_OUTPUT. * Makefile.am: remove ACLOCAL_AMFLAGS, we rely on AC_CONFIG_MACRO_DIR. Mon Jun 24 15:33:34 EDT 2013 Irwin Tillman (irwin at princeton dot edu) * doc/dhcp_probe.8: Updated LIMITATIONS section to warn that some operating system's Ethernet drivers sometimes fail to strip 802.1Q tags from arriving frames before delivering them to the host's logical untagged interface. This prevents the program from hearing those packets. Fri Apr 5 15:13:41 EDT 2013 Irwin Tillman (irwin at princeton dot edu) * doc/dhcp_probe.8: Updated LIMITATIONS section to warn that switches which do not flood DHCP/BootP layer 2 broadcasts prevent dhcp_probe from working. Added TRADEMARKS section. Sat Dec 29 17:15:26 EST 2012 Irwin Tillman (irwin at princeton dot edu) * Upgrade autoconf 2.68 to 2.69. * Upgrade automake 1.11.1 to 1.12.6. * configure.ac: change to single-argument form of AM_INIT_AUTOMAKE. * lib/Makefile.am: remove superfluous INCLUDES. * config/config.guess: replace version 2009-11-20 with version 2012-09-25 from automake 1.12.6. * config/config.sub: replace version 2009-11-20 with version 2012-12-06 from automake 1.12.6. * config/depcomp: replace version 2009-04-28.21 with version 2012-07-12.20 from automake 1.12.7. * config/install-sh: replace version 2009-04-28.21 with version 2011-11-20.07 from automake 1.12.6. * config/missing: replace version 2009-04-28.21 with version 2012-01-06.18 from automake 1.12.6. * config/mkinstalldirs: replace version 2009-04-28.21 with version 2009-04-28.21 from automake 1.12.6. Fri Dec 21 09:40:49 EST 2012 Irwin Tillman (irwin at princeton dot edu) * extras/dhcp_probe_notify2 : Made message sent via $THROTTLE_PAGE_CMD terser. Also added $DO_TRIM_HOSTNAME tunable (defaults to true) to also trim suffix from hostname in message. Thu May 17 10:48:20 EDT 2012 Irwin Tillman (irwin at princeton dot edu) * src/defaults.h: increase MAX_LEGAL_SERVERS from 64 to 512. Wed May 2 14:02:58 EDT 2012 Irwin Tillman (irwin at princeton dot edu) * PLATFORMS: added libpcap 1.2.1. Tue Dec 27 11:52:27 EST 2011 Irwin Tillman (irwin at princeton dot edu) * src/get_myipaddr.c: If our guess of the size of the ifreq structure is less than sizeof(struct ifreq), round it up to sizeof(struct ifreq). This may improve portability to some platforms. Prompted by a related patch proposed by Laurent Guignard (lguignard dot debian at gmail dot com). Wed Dec 14 15:17:20 EST 2011 Irwin Tillman (irwin at princeton dot edu) * src/dhcp_probe.c, src/configfile.c, src/configfile.h, doc/dhcp_probe.8, doc/dhcp_probe.cf.5, extras/dhcp_probe.cf.sample: add support for new do_not_lookup_enet_and_ip_addresses configuration file statement. * extras/site-application-dhcp_probe, extras/dhcp_probe.xml, extras/rotate_logs, extras/README, Makefile.am, Makefile.in: Added sample Solaris SMF method script and manifest file. Added capture file rotation utility optionally used by Solaris SMF method script. * INSTALL: Add step to verify that the probe packets are truly reaching the network, by performing packet capture from another device on that network. * PLATFORMS: updated to reflect that it works Solaris 10. Sat Mar 12 17:20:08 EST 2011 Irwin Tillman (irwin at princeton dot edu) * Upgrade autoconf 2.65 to 2.68. Wed Sep 1 14:50:30 EDT 2010 Irwin Tillman (irwin at princeton dot edu) * src/dhcp_probe.c: When pcap_datalink() != DLT_EN10MB, instead of exiting, skip the rest of the current probe cycle. Thu Jul 15 15:05:33 EDT 2010 Irwin Tillman (irwin at princeton dot edu) * PLATFORMS: updated to reflect that libpcap 1.1.1 works. * TODO: updated to reflect that we don't yet use pcap-config. Mon Mar 22 16:41:19 EDT 2010 Irwin Tillman (irwin at princeton dot edu) * Upgrade autoconf 2.63 to 2.65. * Upgrade automake 1.11 to 1.11.1 * config/config.guess: replace version 2008-01-08 with version 2009-11-20 from automake 1.11.1. * config/config.sub: replace version 2008-01-16 with version 2009-11-20 from automake 1.11.1. * config/depcomp: replace version 2007-03-29.01 with version 2009-04-28.21 from automake 1.11.1. * config/install-sh: replace version 2006-12-25.00 with version 2009-04-28.21 from automake 1.11.1. * config/missing: replace version 2006-05-10.23 with version 2009-04-28.21 from automake 1.11.1. * config/mkinstalldirs: replace version 2006-05-11.19 with version 2009-04-28.21 from automake 1.11.1.

Mon Mar 9 16:04:21 EDT 2009 Irwin Tillman (irwin at princeton dot edu) * Makefile.am: updated list of files in ./extras. * Released version 1.3.0. Thu Feb 19 10:57:58 EST 2009 Irwin Tillman (irwin at princeton dot edu) * At configure time, verify that libnet_cq_end_loop is declared as a result of including libnet.h; if not, refer user to INSTALL.dhcp_probe. * At configure time, verify that libnet_cq_end_loop is defined. If not, refer user to INSTALL.dhcp_probe. Thu Jan 29 18:47:56 EST 2009 Laurent Guignard * doc/dhcp_probe.8: escape -Q Wed Dec 24 09:43:19 EST 2008 Irwin Tillman (irwin at princeton dot edu) * README, INSTALL, doc/dhcp_probe.8: added a paragraph warning that the software should not be run on a network where you don't have permission to do so. Mon Dec 22 14:27:50 EST 2008 Irwin Tillman (irwin at princeton dot edu) * src/configfile.h, src/configfile.c, src/dhcp_probe.c, doc/dhcp_probe.8, doc/dhcp_probe.cf.5, extras/dhcp_probe.cf.sample: add support for new legal_server_ethersrc statement. Mon Dec 8 10:44:21 EST 2008 Irwin Tillman (irwin at princeton dot edu) * src/dhcp_probe.h: re-order dhcp_flavor_t elements, to cause the packets to get sent in the order we want. Fri Dec 5 18:16:52 EST 2008 Irwin Tillman (irwin at princeton dot edu) * src/configfile.h, src/configfile.c, src/dhcp_probe.c, doc/dhcp_probe.8, doc/dhcp_probe.cf.5, extras/dhcp_probe.cf.sample: add support for new 'alert_program_name2' configuration file statement. * extras/dhcp_probe_notify2: added, supports syntax required by the new 'alert_program_name2' configuration file statement. * extras/dhcp_probe_notify: add comment noting that this supports the old syntax used by 'alert_program_name' * extras/README: add dhcp_probe_notify2, update description for dhcp_probe_notify. * INSTALL.dhcp_probe: refer to dhcp_probe_notify2 instead of dhcp_probe_notify. * src/configfile.h, src/configfile.c, src/dhcp_probe.c, doc/dhcp_probe.8, doc/dhcp_probe.cf.5, extras/dhcp_probe.cf.sample, extras/dhcp_probe_notify2: add support for new "Lease Networks of Concern" feature. * extras/mail-throttled: when tie() fails with EAGAIN, retry several times. Add new -T and -S options to tune this. Wed Dec 3 14:38:52 EST 2008 Irwin Tillman (irwin at princeton dot edu) * extras/mail-throttled: add new -l option to also log errors, warnings, and debug output to syslog (in addition to writing to STDERR). * extras/dhcp_probe_notify: when calling mail-throttled, specify -l option. Tue Nov 18 17:23:08 EST 2008 Irwin Tillman (irwin at princeton dot edu) * src/defaults.h: change BOOTP_XID from 0x00000001 to 0x19970112, because we have seen one DHCP server that *might* ignore a DHCP client that specifies BOOTP_XID of 0x00000001. Mon Nov 10 11:20:43 EST 2008 Irwin Tillman (irwin at princeton dot edu) * src/bootp.c: when constructing a DHCP probe packet, place the DHCP Message Type option immediately after the RFC1048 cookie, because we have seen one (broken) DHCP server that *might* only answer DHCP clients if the specifies this option right after the RFC1048 cookie. Mon Oct 20 16:02:49 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * extras/dhcp_probe.startup, extras/dhcp_probe.sh, extras/README: renamed dhcp_probe.startup to dhcp_probe.startup.Solaris9 to make it clearer that this startup script is for Solaris 9. renamed dhcp_probe.sh to dhcp_probe.FreeBSD.sh to make it clearer that this startup script is for FreeBSD. * INSTALL.dhcp_probe, PLATFORMS: move some platform-specific information from INSTALL.dhcp_probe to PLATFORMS. Fri Oct 17 15:16:14 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * Upgraded autoconf 2.62 to 2.63. Fri Oct 10 15:32:41 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * Released version 1.2.2. Mon Oct 6 15:09:13 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * extras/dhcp_probe.startup: added * PLATFORMS: added Mon Oct 6 15:08:53 EDT 2008 Cristian Klein (cristi at net dot utcluj dot ro) * extras/dhcp_probe.sh added Fri Oct 3 17:00:57 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * lib/my_null_proc.c: added * configure.ac: add AC_REPLACE_FUNCS(my_null_proc) to ensure libreplace has at least one member. * configure.ac: add AC_CHECK_HEADERS(net/if_dl.h), AC_CHECK_HEADERS(ifaddrs.h), AC_CHECK_FUNCS(getifaddrs). * src/get_myeaddr.c: if SIOCGIFHWADDR is defined (e.g. Linux), obtain our Ethernet address via ioctl(SIOCGIFHWADDR); else if SIOCGARP is defined (e.g. Solaris 9), obtain our Ethernet address via ioctl(SIOCGARP), else if HAVE_GETIFADDRS is defined (e.g. *BSD), obtain our Ethernet address via getifaddrs(). Fri Oct 3 16:59:59 EDT 2008 Cristian Klein (cristi at net dot utcluj dot ro) * src/get_myipaddr.c: define max() if not defined. Thu Oct 2 14:50:31 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * configure.ac: define STRUCT_ETHER_ADDR_HAS_ETHER_ADDR_OCTET if struct ether_addr{} has an ether_addr_octet member. define STRUCT_ETHER_ADDR_HAS_OCTET if struct ether_addr{} has an octet member. * src/bootp.c(build_frame): use ether_addr.ether_addr_octet or ether_addr.ether_addr_octet.octet based on values of STRUCT_ETHER_ADDR_HAS_ETHER_ADDR_OCTET and STRUCT_ETHER_ADDR_HAS_OCTET. Wed Oct 1 16:45:21 EDT 2008 Andru Luvisi , Leo Weppelman (leo at weppelman dot net> * src/get_myeaddr.c: if SIOCGIFHWADDR is defined, obtain our Ethernet address via ioctl(SIOCGIFHWADDR) instead of ioctl(SIOCGARP). Wed Oct 1 15:05:18 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * src/dhcp_probe.c(my_exit): added. Wraps a (new) log message, cleanup(), and exit(). * src/dhcp_probe.h: declare my_exit(). * src/configfile.c, src/dhcp_probe.c, src/report.c, src/utils.c: use my_exit() when it makes sense. Tue Sep 30 17:44:17 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * src/dhcp_probe.c: use set_pcap_timeout() only when the new '-T' option ('socket receive timeout') is a specified. * doc/dhcp_probe.8: document new -T option Tue Sep 30 17:25:54 EDT 2008 Andru Luvisi * src/dhcp_probe.c(set_pcap_timeout): new * src/dhcp_probe.h: define set_pcap_timeout() Tue Sep 30 15:06:30 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * src/open_max.c, src/open_max.h: added. * src/daemonize.c: call our open_max() instead of relying on OPEN_MAX. Tue Sep 30 13:33:30 EDT 2008 Laurent Guignard (lguignard2000 at yahoo.fr), Cristian Klein (cristi at net dot utcluj dot ro) * src/defaults.h, doc/dhcp_probe.8: change default value of PID_FILE from /etc/dhcp_probe.pid to /var/run/dhcp_probe.pid. Tue Sep 30 13:33:30 EDT 2008 Laurent Guignard (lguignard2000 at yahoo.fr) * src/defs.h: declare __FAVOR_BSD so Linux uses the BSD flavor IP structure headers instead of the Linux flavor headers. Wed Sep 17 13:56:51 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * m4/ist_sys_socket_ioctls_use_streams.m4 rename cache-id from ist_sys_socket_ioctls_use_streams to ist_cv_sys_socket_ioctls_use_streams. * Upgraded autoconf 2.61 to 2.62. Upgraded automake 1.10 to 1.10.1. * config/config.guess: replace version 2006-07-02 with version 2008-01-08 from automake 1.10.1. * config/config.sub: replace version 2006-09-20 with version 2008-01-16 from automake 1.10.1. * config/depcomp: replace version 2006-10-15.18 with version 2007-03-29.01 from automake 1.10.1. * config/install-sh: replace version 2006-10-14.15 with version 2006-12-25.00 from automake 1.10.1. * config/missing: replace version 2006-05-10.23 with version 2006-05-10.23 from automake 1.10.1. Wed Sep 3 14:39:03 EDT 2008 Irwin Tillman (irwin at princeton dot edu) * INSTALL.dhcp_probe: clarify that the patch to libnet may or may not be required for versions of libnet newer than 1.1.2.1. * extras/mail-throttled: use GDBM_File. Improve error messages. * extras/dhcp_probe_notify: improve error messages. Thu Feb 28 18:27:01 EST 2008 Irwin Tillman (irwin at princeton dot edu) * Released version 1.2.1. Sat Feb 9 19:33:55 EST 2008 Irwin Tillman (irwin at princeton dot edu) * configure.ac src/defs.h: When checking if ether_aton(), ether_ntoa(), ether_ntohost(), and ether_hostton() are declared, also check sys/ethernet.h, as that's where they are in Solaris 10. * configure.ac: When checking if ether_aton(), ether_ntoa(), ether_ntohost(), and ether_hostton() are declared, switch from using AC_CHECK_FUNC_PROTO to using AC_CHECK_DECLS so we may specify multiple include files. * src/defs.h: Update the prototypes we provide for ether_aton(), ether_ntoa(), ether_ntohost(), and ether_hostton() when we don't find system-provided prototypes for them. * lib/inet_aton.c: replace version from glibc 2.1.2 with version from glibc 2.7. * configure.ac: add calls to AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T, AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T so we may move to the integer types as per C99. (libnet-specific code will still use the types defined by libnet.) * configure.ac: remove call to AC_UNP_CHECK_TYPE(u_int32_t, unsigned int). On systems where it didn't find a u_int32_t type, it #defined one. On newer platforms, that macro definition could interfere with libnet's typedef of u_int32_t in libnet/libnet-types.h. In newer gcc, this would trigger "error: two or more data types in declaration specifiers". * INSTALL.dhcp_probe: update to reflect that we are known to work with libpcap 0.9.8. Tue Jun 19 15:32:30 EDT 2007 Irwin Tillman (irwin at princeton dot edu) * m4/ac_unp_check_type.m4, configure: upgrade AC_UNP_CHECK_TYPE to 1.6. That fixes its test program to work in gcc 4.1.2.

Wed Nov 22 15:50:47 EST 2006 Irwin Tillman (irwin at princeton dot edu) * configure.ac, configure: correct checks that prevented us from locating , * src/defs.h: for some (more) system header files, only try to include them if configure found them. Fri Nov 4 18:18:44 EST 2005 Irwin Tillman (irwin at princeton dot edu) * Upgraded from automake 1.9.5 to 1.9.6. * config/config.guess: replaced version 2005-02-10 with version 2005-07-08 from automake 1.9.6. * config/config.sub: replaced version 2005-02-10 with version 2005-07-08 from automake 1.9.6. * config/depcomp: replaced version 2005-02-09.22 with version 2005-07-09.11 from automake 1.9.6. * config/install-sh: replaced version 2005-02-02.21 with version 2005-05-14.22 from automake 1.9.6. * config/missing: replaced version 2005-02-08.22 with version 2005-06-08.21 from automake 1.9.6. * config/mkinstalldirs: replaced version 2005-02-02.21 with version 2005-06-29.22 from automake 1.9.6. Mon Oct 10 10:36:57 EDT 2005 Irwin Tillman (irwin at princeton dot edu) * src/dhcp_probe.c: When logging certain errors (malformed packets) in received responses, add the ether_src of the malformed packet. Wed Sep 21 16:25:31 EDT 2005 Irwin Tillman (irwin at princeton dot edu) * src/dhcp_probe.c, src/bootp.c, src/dhcp_probe.h, doc/dhcp_probe.8: add -Q option to specify an 802.1Q VLAN ID for outgoing frames. Thu Apr 7 14:10:37 EDT 2005 Irwin Tillman (irwin at princeton dot edu) * To prevent specific installation instructions from being overwritten by automake, moved specific installation instructions from INSTALL to INSTALL.dhcp_probe, moved generic installation instructions from INSTALL.generic to INSTALL. * Upgraded automake from 1.8.3 to 1.9.5. Sat Dec 25 21:02:19 EST 2004 Irwin Tillman (irwin at princeton dot edu) * INSTALL: remove reference to libnet-config, a utility no longer installed by libnet. Fri Nov 5 10:54:05 EST 2004 Irwin Tillman (irwin at princeton dot edu) * INSTALL: describe change needed to libnet 1.1.2.1 to add libnet_cq_end_loop(). * src/dhcp_probe.c: call libnet_cq_end_loop() after iterating through the libnet context queue, to allow us to iterate through it again on next cycle. Lacking this fix, the program only performs probing once at startup, then all following probe cycles execute without doing any probing. * src/dhcp_probe.c: correct 'writing packet' message to display the libnet context label associated with the probe packet. * Version 1.1.0 released. Thu Nov 4 16:02:38 EST 2004 Irwin Tillman (irwin at princeton dot edu) * m4/ist_require_pcap.m4, m4/ist_require_libnet.m4: When setting LDFLAGS, omit space after -L. Wed Nov 3 17:01:48 EST 2004 Irwin Tillman (irwin at princeton dot edu) * Upgraded from the libnet 1.0.2a API to the libet 1.1.2.1 API. We no longer support the old libnet API.

Wed Oct 27 10:50:57 EDT 2004 Irwin Tillman (irwin at princeton dot edu) * src/defs.h, configure.ac, configure, config.h.in: Only declare ether_ntoa(), ether_addr(), ether_ntohost(), ether_hostton() if they are missing from . * src/dhcp_probe.h: remove duplicate decl of ether_ntoa(), ether_addr(). Tue Sep 7 13:33:53 EDT 2004 Irwin Tillman (irwin at princeton dot edu) * INSTALL: add step to verify 'bootpc' and 'bootps' are in /etc/services or NIS services map. Tue Aug 24 11:17:43 EDT 2004 Irwin Tillman (irwin at princeton dot edu) * Upgraded from autoconf 2.13 to 2.59. Upgraded from automake 1.4 to 1.8.3. * Version 1.0.6 released. Tue Aug 24 10:52:22 EDT 2004 Irwin Tillman (irwin at princeton dot edu) * README, COPYING, Changelog: replace email addresses with human-parseable versions, to reduce spam from simple Web-based address harvesters. * extras/dhcp_probe_notify: add missing my_message() routine, add frequency throttling. * extras/mail-throttled: new. * Version number now 1.0.5.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command './configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the 'README' file for instructions specific to this package. Some packages provide this 'INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The 'configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a 'Makefile' in each directory of the package. It may also create one or more '.h' files containing system-dependent definitions. Finally, it creates a shell script 'config.status' that you can run in the future to recreate the current configuration, and a file 'config.log' containing compiler output (useful mainly for debugging 'configure'). It can also use an optional file (typically called 'config.cache' and enabled with '--cache-file=config.cache' or simply '-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how 'configure' could check whether to do them, and mail diffs or instructions to the address given in the 'README' so they can be considered for the next release. If you are using the cache, and at some point 'config.cache' contains results you don't want to keep, you may remove or edit it. The file 'configure.ac' (or 'configure.in') is used to create 'configure' by a program called 'autoconf'. You need 'configure.ac' if you want to change it or regenerate 'configure' using a newer version of 'autoconf'. The simplest way to compile this package is: 1. 'cd' to the directory containing the package's source code and type './configure' to configure the package for your system. Running 'configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type 'make' to compile the package. 3. Optionally, type 'make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type 'make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the 'make install' phase executed with root privileges. 5. Optionally, type 'make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior 'make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing 'make clean'. To also remove the files that 'configure' created (so you can compile the package for a different kind of computer), type 'make distclean'. There is also a 'make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type 'make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide 'make distcheck', which can by used by developers to test that all other targets like 'make install' and 'make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the 'configure' script does not know about. Run './configure --help' for details on some of the pertinent environment variables. You can give 'configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU 'make'. 'cd' to the directory where you want the object files and executables to go and run the 'configure' script. 'configure' automatically checks for the source code in the directory that 'configure' is in and in '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use 'make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple '-arch' options to the compiler but only a single '-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the 'lipo' tool if you have problems. Installation Names ================== By default, 'make install' installs the package's commands under '/usr/local/bin', include files under '/usr/local/include', etc. You can specify an installation prefix other than '/usr/local' by giving 'configure' the option '--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option '--exec-prefix=PREFIX' to 'configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like '--bindir=DIR' to specify different values for particular kinds of files. Run 'configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of '${prefix}', so that specifying just '--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to 'configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the 'make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, 'make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of '${prefix}'. Any directories that were specified during 'configure', but not in terms of '${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the 'DESTDIR' variable. For example, 'make install DESTDIR=/alternate/directory' will prepend '/alternate/directory' before all installation names. The approach of 'DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of '${prefix}' at 'configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving 'configure' the option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. Some packages pay attention to '--enable-FEATURE' options to 'configure', where FEATURE indicates an optional part of the package. They may also pay attention to '--with-PACKAGE' options, where PACKAGE is something like 'gnu-as' or 'x' (for the X Window System). The 'README' should mention any '--enable-' and '--with-' options that the package recognizes. For packages that use the X Window System, 'configure' can usually find the X include and library files automatically, but if it doesn't, you can use the 'configure' options '--x-includes=DIR' and '--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of 'make' will be. For these packages, running './configure --enable-silent-rules' sets the default to minimal output, which can be overridden with 'make V=1'; while running './configure --disable-silent-rules' sets the default to verbose, which can be overridden with 'make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX 'make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as 'configure' are involved. Use GNU 'make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its '' header file. The option '-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put '/usr/ucb' early in your 'PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in '/usr/bin'. So, if you need '/usr/ucb' in your 'PATH', put it _after_ '/usr/bin'. On Haiku, software installed for all users goes in '/boot/common', not '/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features 'configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, 'configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the '--build=TYPE' option. TYPE can either be a short name for the system type, such as 'sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file 'config.sub' for the possible values of each field. If 'config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option '--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with '--host=TYPE'. Sharing Defaults ================ If you want to set default values for 'configure' scripts to share, you can create a site shell script called 'config.site' that gives default values for variables like 'CC', 'cache_file', and 'prefix'. 'configure' looks for 'PREFIX/share/config.site' if it exists, then 'PREFIX/etc/config.site' if it exists. Or, you can set the 'CONFIG_SITE' environment variable to the location of the site script. A warning: not all 'configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to 'configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the 'configure' command line, using 'VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified 'gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash 'configure' Invocation ====================== 'configure' recognizes the following options to control how it operates. '--help' '-h' Print a summary of all of the options to 'configure', and exit. '--help=short' '--help=recursive' Print a summary of the options unique to this package's 'configure', and exit. The 'short' variant lists options used only in the top level, while the 'recursive' variant lists options also present in any nested packages. '--version' '-V' Print the version of Autoconf used to generate the 'configure' script, and exit. '--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally 'config.cache'. FILE defaults to '/dev/null' to disable caching. '--config-cache' '-C' Alias for '--cache-file=config.cache'. '--quiet' '--silent' '-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to '/dev/null' (any error messages will still be shown). '--srcdir=DIR' Look for the package's source code in directory DIR. Usually 'configure' can determine that directory automatically. '--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. '--no-create' '-n' Run the configure checks, but stop before creating any output files. 'configure' also accepts some other, not widely useful, options. Run 'configure --help' for more details. '..'. This is known as a "VPATH" build. With a non-GNU 'make', it is safer to compile the package for one archidhcp_probe-1.3.1/NEWS000064400000000000000000000233321400135702700143540ustar00rootroot00004560370030dhcp_probe NEWS - history of user-visible changes. See the file ChangeLog for the details of all changes. Version 1.3.1 - January 18 2021, by Irwin Tillman * When the interface link type is not Ethernet, we used to treat that as a permanent error, and exited. We now treat it as a transient error, just logging it and skipping the rest of the current probe cycle. This was prompted by a change (bug ?) that appeared in libpcap sometime after version 0.9.8. The behavior is present by libpcap version 1.1.1. It remains (at least) through version 1.4.0. On occassion, pcap_datalink() returns DLT_NULL instead of DLT_EN10MB when pointed to an Ethernet interface. * The new 'do_not_lookup_enet_and_ip_addresses' configuration file statement may be used to specify that the program should not try to look up the network interface's Ethernet address (and IP address if necessary). This may allow the program to operate on network interfaces and platforms where those lookup operations would not work. It may also permit operation on a network interface which has no assigned IP address. Specifying 'do_not_lookup_enet_and_ip_addresses' requires that the 'ether_src' and 'chaddr' statements also appear in the configuration file. * Previously if a response frame arrived with ether_type == ETHERTYPE_VLAN (802.1Q tagging), we ignored the frame. We did not expect to receive such frames because we expect to operate on an untagged network interface. (Possibly a logical network interface for which the OS has already stripped the incoming 802.1Q tags.) Now we do not ignore the frame if its VLAN ID == 0. 802.1Q says such frames should be treated like untagged frames. Some ethernet drivers may deliver such frames even to an "untagged" logical network interface. They might choose to do so, for example, when the incoming frame contained a non-zero 802.1p priority. To avoid discarding the priority when delivering the frame to an untagged logical network interface, the driver might choose to retain the 802.1Q header, changing the VLAN ID to 0. * Previously if a request to quit arrived while we were waiting for packets in response to a probe packet, the program could postpone quitting forever in environments in which no DHCP servers responded to the probe packet. * Previously the response_wait_time was not respected on those platforms where the read timeout used by pcap is not supported. After sending a probe packet, we might wait less than response_wait_time. We might see only the first response packet. Now we try to wait the entire response_wait_time. * The messages sent by dhcp_probe_notify2 via the THROTTLE_PAGE_CMD are slightly terser to reduce the likelihood they will be split or truncated by SMS providers which split/truncate messages at fewer than 160 characters. * If you apply the new libnet_cq_destroy() patch to libnet (or run a version newer than libnet 1.2rc3), this fixes a crash when we handle SIGHUP. Version 1.3.0 - March 9 2009, by Irwin Tillman * The "received unexpected response ..." message passed to syslog() now always ends with a period. If you parse this message, you may need to update your code. * New optional 'alert_program_name2' configuration file statement. This works like the older 'alert_program_name', but calls an alert program using a different syntax, intended to be extensible. (The existing 'alert_program_name' called an alert program using positional arguments, so was not extensible without breaking existing alert programs. That limited our ability to enhance dhcp_probe to pass additional information to the alert program. The new 'alert_program_name2' calls an alert program using options.) The older optional 'alert_program_name' statement continues to be supported and unchanged. If you are using that, you need not change. However, you may wish to upgrade to the new alert_program_name2; if you do so, you will need to replace or revise the alert program so it supports the new call syntax. See "New dhcp_probe_notify2 program" item below. You may not specify both an alert_program_name and an alert_program_name2 in the same configuration file. * New dhcp_probe_notify2 program. This program is like the older dhcp_probe_notify program (which continues to be supported), but supports the new syntax expected by the new 'alert_program_name2' configuration file statement. If you are currently using the supplied dhcp_probe_notify alert program, and you have not modified it (other than to update the definitions at the top), you should be able to switch to the new dhcp_probe_notify2 easily; you will need to replace the alert_program_name statement in your configuration file with the alert_program_name2 statement, specify alert program dhcp_probe_notify2 instead of dhcp_probe_notify2, and customized the definitions at the top of dhcp_probe_notify2 to match the definitions you customized in dhcp_probe_notify. dhcp_probe_notify2 also accepts a new option so it can report a 'yiaddr' value when the new "Lease Networks of Concern" feature is triggered. * New "Lease Networks of Concern" feature. This is intended to add more text to the messages logged (and via alerts) when a rogue DHCP server is distributing IP addresses that fall into network ranges of special concern -- for example, *your* networks' IP ranges. Most rogue DHCP servers distribute IP addresses associated with a private network, or NAK legitimate clients. Rogue DHCP servers that distribute your own network's addresses may be of special concern. To activate this new feature, add 'lease_network_of_concern' statements to the configuration file to specify network ranges. When dhcp_probe detects a response from a rogue DHCP server, if the response's yiaddr field is non-zero and falls within any of the "Lease Networks of Concern", that fact will be reported. Specifically, the "received unexpected response ..." message sent to syslog() will be extended to add additional text reporting the value of the yiaddr field. And if you have specified an 'alert_program_name2' in the configuration file, that alert program will be called with the new '-y yiaddr' option. (If you are still using the older 'alert_program_name', the alerts will not contain this additional information, as the old alert_program_name doesn't support this change.) * New "legal_server_ethersrc" test. The program traditionally compares the IP source address of response packets to the values specified by "legal_server" statements in the configuration file. Any response with an IP source address that doesn't appear as a legal_server is treated as a rogue server. The new legal_server_ethersrc configuration statement allows you to also check the Ethernet source address of response packets. If you do not specify any legal_server_ethersrc statements, the program continues to behave as it has in the past. If you specify one or more legal_server_ethersrc statements, the program will check the Ethernet source address of response packets to verify they appear among those listed. Any response from an unlisted Ethernet source address is treated as a rogue server. This test is done in addition to the legal_server test. So if you specify by legal_server and legal_server_ethersrc statements, a response's IP source and Ethernet source addresses are both checked; if either is missing from those you specified, the response is treated as a rogue. This new test is considered experimental in version 1.3.0, as it has received only limited testing. Version 1.2.2 - October 15 2008, by Irwin Tillman * The default name of the pid file has changed from /etc/dhcp_probe.pid to /var/run/dhcp_probe.pid. You can still override the default by specifying the '-p pidfile' command line option. * New -T option to enable the 'socket receive timeout' feature. This may work around a problem on some platforms where the program waits forever for responses after sending a probe packet. This new feature does not work on all platforms. * When exiting, the program will more consistently log an "exiting" message. Version 1.2.1 - February 28 2008, by Irwin Tillman * No user-visible changes. Version 1.2.0 - March 14 2007, by Irwin Tillman * Upgraded autoconf and automake, may build on newer systems. * Allow you to add 802.1Q VLAN ID to outgoing frames. Version 1.1.0 - November 10 2004, by Irwin Tillman * Upgraded from the libnet 1.0.x API to the libnet 1.1.x API. We no longer support the libnet 1.0.x API. To compile this version, you must first upgrade libnet to 1.1.2.1. Additionally, you must modify libnet to add a libnet_cq_end_loop() function, as described in our INSTALL document. Version 1.0.7 - November 2 2004, by Irwin Tillman * No user-visible changes. Version 1.0.6 - August 24 2004, by Irwin Tillman * Upgraded autoconf and automake, may build on newer systems. Version 1.0.5 - August 24 2004, by Irwin Tillman * We make some effort to ignore BootP/DHCP responses we happen to capture that aren't actually in response to our probe (we check htype, hlen, and chaddr fields). Version 1.0.4 - May 2002, by Irwin Tillman * We should be able to compile under gcc 3.0.x now. Version 1.0.3 - February 2001, by Irwin Tillman * No user-visible changes. Version 1.0.2 - January 2001, by Irwin Tillman * Cleanup of some of the configuration code. You may now specify where libnet and libpcap libraries and includes are located. Version 1.0.1 - August 2000, by Irwin Tillman * Added alert_program_name feature, so you may specify an external program to run each time a response is received from an unexpected server. Version 1.0.0 - June 2000, by Irwin Tillman * first version gram_name2 statement, specify alert program dhcp_probe_notify2 instead of dhcp_probe_notify2, and customized the definitions at the top of dhcp_probe_notify2 to match the definitions you customized in dhcp_probe_notify. dhcp_probe_notify2 also accepts a new option so it can report a dhcp_probe-1.3.1/README000064400000000000000000000045161400135702700145400ustar00rootroot00004560370030README for dhcp_probe This is dhcp_probe. dhcp_probe is intended to be used by a network administrator to locate unknown BootP and DHCP servers on a directly-attached network. This software was created by the Network Systems Group at Princeton University's Office of Information Technology, networking at princeton dot edu. It was written by Irwin Tillman. It is available from: https://www.net.princeton.edu/software/dhcp_probe/ This version runs on Solaris 10 on SPARC, compiled with gcc. This version supports only Ethernet interfaces. dhcp_probe is intended for use by a network administrator. Before running dhcp_probe on any network other than one for which you are responsible, contact that network's administrator to learn if it is acceptable for you to run this software on that network. Running this software on a network where you don't have permission to do so may violate that network's acceptable use policy. It was intended for our use at Princeton University, so was written to operate on the platform(s) we use, with the features we need. As others have asked for the software, we've made it generally available, however, we do not have the resources available to port it to additional platforms or add features. See the file INSTALL.dhcp_probe for installation instructions. Generic building and installation instructions are in INSTALL. Platform-specific notes are in PLATFORMS. The file NEWS describes recent user-visible changes to dhcp_probe. The product is free, however, it includes code that was published in other programs; those parts are subject to copyright and certain restrictions. See the file COPYING for specifics. This software is provided "as is" and any express or implied warranties, including, but not limited to, the implied warranties of mechantability and fitness for a particular purpose are disclaimed. In no event shall the authors or Princeton University be liable for any direct, indirect, incidental, special exemplary, or consequential damages (including, but not limited to, procurement of substitute goods or services; loss of use, data, or profits; or business interruption) however caused and on any theory of liability, whether in contract, strict liability, or tort (including negligence or otherwise) arising in any way out of the use of this software, even if advised of the possibility of such damage. dhcp_probe-1.3.1/TODO000064400000000000001000000033751141765646000145240ustar00rootother00004560370030TODO for dhcp_probe If the legal_server_ethersrc feature passes additional testing, update the documentation to stop referring to it as "experimental."

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. ect code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense dhcp_probe-1.3.1/INSTALL.dhcp_probe000064400000000000000000000175011400135702700170130ustar00rootroot00004560370030Installing dhcp_probe Note that the file INSTALL contains generic build and installation instructions; it supplements this file (specifically, the steps involving 'configure', 'make', and 'make install'). The file PLATFORMS contains platform-specific notes. dhcp_probe is intended for use by a network administrator. Before running dhcp_probe on any network other than one for which you are responsible, contact that network's administrator to learn if it is acceptable for you to run this software on that network. Running this software may violate on a network where you don't have permission to do so may violate that network's acceptable use policy. --- 1. Obtain and install libpcap, the packet capture library. Version 0.8.1 or later is required. It is available from http://www.tcpdump.org More information about which versions of libpcap the program has been successfully used with (and whether any versions should be avoided), may appear in the PLATFORMS file. If libpcap isn't supported on your platform, you can't use dhcp_probe. Libpcap must be installed to compile dhcp_probe; we assume we'll find the libpcap library and header files in either /usr/local or the other usual places the compiler and linker will search. If you've installed it elsewhere, when you run 'configure' below, remember to specify the --with-pcap=DIR option. -- 2. Obtain and install libnet 1.1.x, the packet writing library. It is available from http://packetfactory.openwall.net/projects/libnet/index.html The current version of this program uses the libnet 1.1.x API. It does not support the libnet 1.0.x API. (The last version of this program that supported the libnet 1.0.x API was version 1.0.7.) More information about which versions of libnet the program has been successfully used with (and whether any versions should be avoided), may appear in the PLATFORMS file. If libnet 1.1.x isn't supported on your platform, you can't use dhcp_probe. Libnet must be installed to compile this program; we assume we'll find the libnet library and header files in either /usr/local or the other usual places the compiler and linker will search. If you've installed it elsewhere, when you run 'configure' below, remember to specify the --with-libnet=DIR option. Additionally, if you are using libnet older than version 1.3, you likely need to modify libnet to add a function that we need to use. This function is not present in libnet 1.1.x until version 1.3, so you will need to patch libnet. In the libnet source directory, edit ./src/libnet_cq.c to add the following at the end: u_int32_t libnet_cq_end_loop() { if (! clear_cq_lock(CQ_LOCK_WRITE)) { return (0); } l_cqd.current = l_cq; return (1); } In the libnet source directory, edit ./include/libnet/libnet-functions.h to add the following at the end: u_int32_t libnet_cq_end_loop(); Additionally, if you are using libnet version up through version 1.2rc3, you should modify libnet to fix a bug that we would otherwise trigger when handling SIGHUP. (This bug fix was commited after libnet 1.2rc3, so is expected to be in the next libnet release after that.) In the libnet source directory, edit ./src/libnet_cq.c to modify libnet_cq_destroy() to append the following two statements to the end of the function: l_cq = NULL; memset(&l_cqd, 0, sizeof(l_cqd)); You will need to rebuild and install libnet to incorporate these changes. --- 3. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. You may need to specify the --with-pcap=DIR option if configure is unable to locate the libpcap header and library. If the header and library don't share a common parent, the more specific options --with-pcap-include=DIR and --with-pcap-lib=DIR may be useful. You may need to specify the --with-libnet=DIR option if configure is unable to locate the libnet header and library. If the header and library don't share a common parent, the more specific options --with-libnet-include=DIR and --with-libnet-lib=DIR may be helpful. For example, on some platforms, libnet 1.1.x is installed below /usr/include/libnet11/ and /usr/lib/libnet11/. More information about running 'configure' is available in the INSTALL file, and you may type './configure --help' for a summary of options. Additional notes about some platforms may be in the PLATFORMS file. --- 4. Type `make' to compile the package. Ignore the following compiler warning: bootp.c: In function `build_dhcp_payload': bootp.c:80: warning: assignment from incompatible pointer type If you see an error about libnet_cq_end_loop() being unknown, see the earlier step about modifying libnet to add this function. --- 5. Type `make install' to install the package. --- 6. Create a configuration file dhcp_probe.cf in an appropriate location. The default location for this file is /etc/dhcp_probe.cf, but you can put it elsewhere, as long as you specify the new location when you run the program using the appropriate command-line option. A sample configuration file is supplied in the 'extras' directory; you may wish to use it as a template. 7. Verify that the /etc/services file (or NIS 'services' map, whichever is in-use) contains entries for 'bootpc' and 'bootps'. If they are not present, add them: bootps 67/udp # BOOTP/DHCP server bootpc 68/udp # BOOTP/DHCP client --- 8. To get started, try running it in the foreground and seeing if the debug messages seem reasonable to you. E.g. as root: /usr/local/sbin/dhcp_probe -f -d 11 hme0 The -f option prevents it from forking, and also causes all output to be sent to stderr instead of to syslog. Debuglevel 11 will produce maximum debugging. Specify the name of the interface on which to run, e.g. 'hme0'. --- 9. Verify that the probe packets transmitted by dhcp_probe are truly reaching the network. Do so by performing packet capture from another device on the network. Do not skip this step, as it may help you discover whether some problem is silently causing the packets to never reach the network. Do not rely on packet capture performed from the device running dhcp_probe, as such capture will likely see the outgoing packets on their way to the network interface, rather than the actual packets on the network. --- 10. Arrange to have the program started automatically by root when your host starts. Some sample startup scripts are in the extras directory. Never specify the -f flag when starting the daemon from a startup script; this flag should never be specified except for debugging purposes. You'll probably want to reduce the debuglevel; a debuglevel of 0 or 1 is generally a good choice for production use. Output will be directed to syslog (using the facility specified in defaults.h); you'll want to configure syslogd to do something reasonable with it. (You can change the syslog facility name by editing defaults.h and recompiling.) Alternatively, use the -l option to specify a logfile to receive output; this prevents syslog from being used. --- 11. If you want to capture packets received from unknown servers, add the -o option when starting up, to specify a capture file. Be sure to specify a directory for the capture file that no one may write to except root; see the dhcp_probe(8) man page for details. Since the program truncates this file each time it starts, you may want to modify the script you use to start the program, to save the old version of this file before starting the program. --- 12. Any additional tools you may find useful can be found in the 'extras' directory. For example, extras/dhcp_probe_notify2 is a sample notification script that may be called via the 'alert_program_name2' configuration file statement. There are some sample startup scripts in that directory as well. See the README file in that directory. --- dhcp_probe-1.3.1/PLATFORMS000064400000000000000000000063631400135702700151540ustar00rootroot00004560370030Platform-Specific Notes for dhcp_probe The author develops this program on Solaris 10 on SPARC, so that is a platform you can expect to work. The author has not ported the program to other platforms, and in fact, it currently ignores much of what 'configure' discovers. Others have contributed patches to make this program run on several other platforms. The author is usually unable to test whether these patches work on those platforms. FREEBSD If the libnet 1.1.x header is installed in /usr/local/include/libnet11/ you will probably need to specify --with-libnet-include=/usr/local/include/libnet11/ If the libnet 1.1.x library is installed in /usr/local/lib/libnet11/ you will probably need to specify --with-libnet-lib=/usr/local/lib/libnet11/ You may need to specify --mandir=/usr/local/man at configure-time. SOLARIS The current version of the program has been successfully built and used on the following versions of Solaris: Solaris 10 on SPARC gcc 4.4.7 libpcap 1.4.0 libnet 1.1.2.1 (with the libnet_cq_end_loop() change described in INSTALL.dhcp_probe) Solaris 10 on SPARC gcc 4.4.7 libpcap 1.4.0 libnet 1.1.2.1 (with the libnet_cq_end_loop() and libnet_cq_destroy changes described in INSTALL.dhcp_probe) Earlier versions of the program has been successfully built and used on on the following versions of Solaris;

A network administrator can use this tool to locate unauthorized DHCP and BootP servers. .PP The program must be run with root privilege. .PP The program periodically broadcasts a number of DHCP and BootP request packets out a single physical interface. Several different kinds of request packets are sent, as a DHCP or BootP server may only respond to certain requests, depending on the server's configuration. Essentially, dhcp_probe mimics a BootP or DHCP client in a variety of possible states, attempting to provoke responses from servers. .PP After sending each request packet, dhcp_probe listens for responses. After filtering out responses that do not appear to be in response to the probe, and responses from known DHCP and BootP servers (identified by their IP source addresses and optionally by their Ethernet source addresses), it logs any responses from unknown servers. .PP Optionally, responses from unknown servers may also be written to a packet capture file. .PP Optionally, an external program may be called each time a response from an unknown server is received. .PP dhcp_probe may not be able to locate all DHCP and BootP servers; see LIMITATIONS below. .PP As DHCP broadcasts do not ordinarily cross IP routers, dhcp_probe will locate only servers that are attached to the same physical network as the interface specified on the command line. Although BootP Relay Agents running on this network may help the broadcasts cross IP routers, these agents typically are configured to convert the broadcasts to unicasts directed to only the well-known DHCP or BootP servers located on other physical networks. As a result, BootP Relay Agents will allow your the servers to receive the requests issued by dhcp_probe, but will not cause remote unknown servers to hear these requests. Therefore, if you have multiple physical networks, you may wish to run dhcp_probe on each of these networks to discover unknown DHCP and BootP servers on each of them. .PP dhcp_probe functions on a single Ethernet interface specified on the command line; it does not listen on multiple interfaces. However, if the host has multiple physical or logical interfaces, you may run an instance of dhcp_probe on each physical or logical interface. If your physical interface supports 802.1Q, you can use that to create a logical (untagged) interface on each VLAN, then run an instance of dhcp_probe on each logical (untagged) interface. .PP dhcp_probe is intended for use by a network administrator. Before running dhcp_probe on any network other than one for which you are responsible, contact that network's administrator to learn if it is acceptable for you to run this software on that network. Running this software on a network where you don't have permission to do so may violate that network's acceptable use policy. .SH AVAILABILITY .PP dhcp_probe is a product of the Network Systems Group at Princeton University's Office of Information Technology, and is available from https://www.net.princeton.edu/software/dhcp_probe/ .PP Presently the product builds and runs on Solaris 10 on SPARC with gcc. The program relies on the .BR pcap (3) and .BR libnet (3) libraries. .SH OPTIONS .TP .IB \-c \ config_file Specifies the configuration file. If not specified, this defaults to .BR /etc/dhcp_probe.cf . The configuration file is read at startup, and is re-read whenever a SIGHUP is received. See .BR dhcp_probe.cf (5). .TP .BI \-d \ debuglevel Sets the .I debuglevel variable that controls the amount of debugging messages generated. If not specified, this defaults to 0 (no debugging). For a summary of the types of messages produced at each debug level, see DEBUG LEVELS below. .TP .B \-f Specifies that the program should not fork, but instead remain in the foreground. Only use this when you are starting the program manually for testing purposes. When in the foreground, any messages produced by the program are written to .IR stderr instead of to .BR syslog (3) or any .I log_file you might specify with the .B \-l option. .TP .B \-h Display a brief usage summary, then exit. .TP .BI \-l \ log_file Log messages to the specified file instead of to .BR syslog (3). (This option is ignored if you also specify the .B \-f option, as that directs messages to .IR stderr .) The log file is opened shortly after the program starts. It is closed and re-opened when the program receives a SIGUSR1 signal. .TP .BI \-o \ capture_file When a response packet is received from an unexpected server, write the packet to the specified file. The file is opened and truncated shortly after the program starts. It is closed and re-opened (and truncated) when the program receives a SIGUSR2 signal. The file is a .BR pcap (3) savefile, and may be read with any program that understands the pcap savefile format; e.g. .BR tcpdump (1). .TP .BI \-p \ pid_file Specifies the file that will contain the program's processid. If not specified, this defaults to .BR /var/run/dhcp_probe.pid . The .I pid_file is written shortly after the program starts, and is removed when the program exits under its own control. .TP .BI \-Q \ vlan_id Specifies that when the program constructs a packet to send, it should add an 802.1Q tag with the specified vlan_id. Valid values range from 0 to 4095. If not specified, the program does not add an 802.1Q tag to the packets it constructs. (The operating system or Ethernet driver may still do so.) .TP .BI \-s \ capture_bufsize Specifies the size of the buffer that will be used to capture all the responses (Ethernet frames) to a single request packet; responses which do not fit are silently dropped. The value is specified in bytes, and must fit into your host's range for an .IR int ; values outside that range may result in unpredictable results. If not specified, this defaults to 30280, which is enough for twenty maximum-size Ethernet frames (1514*20). Typical responses are Ethernet frames ranging from 342-590 bytes, so the default capture buffer size should hold over 50 of them. .TP .B \-T Enables the 'socket receive timeout' feature. On some platforms, dhcp_probe may ignore the .I response_wait_time (described in .BR dhcp_probe.cf (5)), instead waiting forever for a response after it sends a probe packet. As per .BR pcap (3), this is because the read timeout we pass to pcap_open_live() is not supported on all platforms. If you encounter this issue, try enabling our 'socket receive timeout' feature; it might help. Enabling this feature causes the program to also set a socket receive timeout on the socket underlying the pcap capture; we set this timeout to the .IR response_wait_time . On some platforms, the program's socket receive timeout feature does not work; instead the program will report that it cannot set the receive timeout, and will exit. .TP .B \-v Display the program's version number, then exit. .TP .IB \-w \ cwd Specifies the working directory; shortly after starting the program changes its current working directory to this. If not specified, this defaults to .IR / . .TP .I interface_name Specifies the name of the interface the program should use; this argument is required. This must be an Ethernet interface which is up. Typically this interface must also have an IP address assigned; specifying .B do_not_lookup_enet_and_ip_addresses in .BR dhcp_probe.cf (5) may allow the program to operate on an interface which lacks an IP address. .BB .SH OPERATION .PP After initialization, the program enters its main event loop, in which it remains until you signal the program to exit with a SIGINT, SIGTERM, or SIGQUIT. .PP The main event loop (a.k.a. the "probe cycle") consists of the following actions, repeated until the program receives a request to quit: .RS 5 .TP 1. Handle any signals that have been received. .TP 2. Install a .BR pcap (3) filter to listen for UDP packets destined to the BootP client port (UDP port 68). .TP 3. Broadcast a DHCP or BootP request packet out the specified interface. .TP 4. Listen for .I response_wait_time milliseconds for any responses received by the .BR pcap (3) filter. (The .I response_wait_time defaults to 5000 milliseconds (5 seconds), and may be changed in the .IR dhcp_probe.cf (5) file.) .sp Any responses that contains a bootp_chaddr field not equal to the chaddr used in the probe is ignored, as are any that have incorrect bootp_htype or bootp_hlen fields. These are not responses to our probe. .sp Any responses from known DHCP and BootP servers are ignored. The IP source address for responses from each known server is declared using a .B legal_server statement in the .IR dhcp_probe.cf (5) file. Any response with an IP source address that does not appear in a .B legal_server statement is treated as an unknown server. .sp The Ethernet source address for responses from each known server is also optionaly declared using a .B legal_server_ethersrc statement in the .IR dhcp_probe.cf (5) file. If at least one .B legal_server_ethersrc is specified, then any response with an Ethernet source address that does not appear in a .B legal_server_ethersrc statement is treated as an unknown server. If no .B legal_server_ethersrc statements appear, then the response's Ethernet source address is not checked. (The .B legal_server_ethersrc statement is considered experimental in versions 1.3.0 - 1.3.1, as it has received only limited testing.) .sp For each response from an unknown server: .TP 10 a) If the reponse packet contains a non-zero .BI yiaddr field, and one or more .B lease_network_of_concern statements were specified, determine if the .B yiaddr value falls within any of the "Lease Networks of Concern". .TP 10 a) Log a message showing the response packet's source IP and Ethernet addresses. If the response packet's yiaddr is non-zero and falls within a "Lease Networks of Concern", the log message also reports that. .TP 10 b) If the .B \-o option was specified, the packet is also written to a packet capture file. .TP 10 c) If an .I alert_program_name was specified in the .IR dhcp_probe.cf (5) file, that program is executed, with the following arguments in order: the name of the calling program (e.g. .BR dhcp_probe ), the name of the interface on which the unexpected response packet was received, the IP source address of the packet, and the Ethernet source address of the packet. (We do not wait for the .I alert_program_name to complete; it runs in a child process.) .TP 10 d) If an .I alert_program_name2 was specified in the .IR dhcp_probe.cf (5) file, that program is executed, with the following required options: .nf \-p the name of the calling program (e.g. dhcp_probe) \-I the name of the interface on which the unexpected response packet was received \-i the IP source address of the packet \-m and the Ethernet source address of the packet .fi If the response packet's yiaddr is non-zero and falls within a "Lease Networks of Concern", the following optional options are also passed: .nf \-y the non-zero yiaddr value .fi (We do not wait for the .I alert_program_name2 to complete; it runs in a child process.) .TP 5. Remove the .BR pcap(3) filter installed earlier. .TP 6. If any signals have arrived requesting that we quit, exit gracefully. .TP 7. Repeat steps 2-6 for each flavor of DHCP and BootP request packet the program supports (see PACKET FLAVORS below). .TP 8. Handle any signals that have been received. .TP 9. Sleep for .I cycle_time seconds. (The .I cycle_time defaults to 300 seconds, and and may be changed in the .IR dhcp_probe.cf (5) file.) .RE .PP The .BR pcap (3) filter the program installs normally does not specify that the interface should be placed into promiscuous mode (although it is possible the interface is already in promiscuous mode for some other reason). However, if in the .BR dhcp_probe.cf (5) file you specify a .I chaddr or .I ether_src value other than the interface's actual hardware address, then the pcap filter .I will specify that the interface should be placed into promiscuous mode. .PP Although the filter used with .BR pcap (3) specifies only UDP packets destined to port .I bootpc should be collected, on systems where .I bpf isn't part of the kernel, .BR pcap (3) must implement .I bpf as part of the application. This can increase the number of packets that must be passed from the kernel to user space to be filtered. The program attempts to minimize the side-effects of this by removing the .BR pcap (3) filter when it isn't actually listening for responses. In particular, the filter is not installed during the time the program sleeps between each probe cycle (the .IR cycle_time ). .PP If you do specify an .IR alert_program_name , take care that the program you specify is safe for a privileged user to run; it is executed with the same (i.e. root) privileges as the calling program. .SH "PACKET FLAVORS" No single request packet is likely to provoke a response from every possible BootP and DHCP server. Some servers may only response to either BootP, or DHCP, but not both. Some servers may be configured to only respond to a small set of known clients. Some DHCP servers will only provide leases to a small set of known clients, but may be willing to respond (negatively) to unknown clients that request a lease renewal on an inappropriate IP address. Therefore, dhcp_probe actually sends not one, but five different flavor request packets, in the hopes of provoking responses from a wider variety of unknown servers. .PP The packet flavors are: .TP BOOTPREQUEST This packet is typical of a BootP client requesting an IP address. .sp It will typically provoke a BOOTPREPLY from a BootP server willing to respond to any BootP client. (BootP servers configured to only respond to a set of known clients may not respond.) .TP DHCPDISOVER (INIT) This packet is typical of a DHCP client in the INIT state. .sp The options field contains a DHCP Message Type specifying DHCPDISCOVER. .sp The options field contains a DHCP Client Identifier, which is computed by prepending 0x'01' to the value of .IR chaddr . (The value .I chaddr is specified in the .BR dhcp_probe.cf (5) file, otherwise it defaults to the interface's Ethernet address.) .sp This packet will typically provoke a DHCPOFFER from a DHCP server willing to respond to any DHCP client. (DHCP servers configured to only offer leases to a set of known clients may not respond.) .TP DHCPREQUEST (SELECTING): This packet is typical of a DHCP client in the SELECTING state; i.e. a client which has previously issued a DHCPDISCOVER, then received a DHCPOFFER from some DHCP server. .sp The options field contains a DHCP Message Type specifying DHCPREQUEST. .sp The options field contains a DHCP Client Identifier, which is computed by prepending 0x'01' to the value of .IR chaddr . (The value .I chaddr is specified in the .BR dhcp_probe.cf (5) file, otherwise it defaults to the interface's Ethernet address.) .sp The options field contains a DHCP Server Identifier specifying .IR server_id , which should be an IP address that does not correspond to any valid DHCP Server Identifier on your network. (The value .I server_id is specified in the .BR dhcp_probe.cf (5) file, otherwise it defaults to 10.254.254.254.) .sp The options field contains a DHCP Requested IP Address specifying .IR client_ip_address , which should be an IP address that does not correspond to any valid IP address on your network. (The value .I client_ip_address is specified in the .BR dhcp_probe.cf (5) file, otherwise it defaults to 172.31.254.254.) .sp This packet occassionally provokes a response from a broken DHCP server that fails to respect the DHCP Server Identifier option. .TP DHCPREQUEST (INIT-REBOOT): This packet is typical of a DHCP client in the INIT-REBOOT state; i.e. a client which has obtained a DHCP lease in the past, is bringing up its IP stack, and hopes to obtain (or extend) a DHCP lease on the same IP address as in the past. .sp The options field contains a DHCP Message Type specifying DHCPREQUEST. .sp The options field contains a DHCP Client Identifier, which is computed by prepending 0x'01' to the value of .IR chaddr . (The value .I chaddr is specified in the .BR dhcp_probe.cf (5) file, otherwise it defaults to the interface's Ethernet address.) .sp The options field contains a DHCP Requested IP Address specifying .IR client_ip_address , which should be an IP address that does not correspond to any valid IP address on your network; ideally it should be one that is topologically inappropriate for your network. (The value .I client_ip_address is specified in the .BR dhcp_probe.cf (5) file, otherwise it defaults to 172.31.254.254.) .sp If the Requested IP Address option is topologically inappropriate for your network, this packet may provoke a DHCPNAK from any DHCP server that believes it is authoritative for the network's IP topology. .TP DHCPREQUEST (REBINDING) This packet is typical of a DHCP client in the REBINDING state; i.e. a client which has obtained a DHCP lease which is between its DHCP T2 and expiration time. .sp The options field contains a DHCP Message Type specifying DHCPREQUEST. .sp The options field contains a DHCP Client Identifier, which is computed by prepending 0x'01' to the value of .IR chaddr . (The value .I chaddr is specified in the .BR dhcp_probe.cf (5) file, otherwise it defaults to the interface's Ethernet address.) .sp The ciaddr field contains .IR client_ip_address , which should be an IP address that does not correspond to any valid IP address on your network; ideally it should be one that is topologically inappropriate for your network. (The value .I client_ip_address is specified in the .BR dhcp_probe.cf (5) file, otherwise it defaults to 172.31.254.254.) .sp If the value of ciaddr is topologically inappropriate for your network, this packet will provoke a DHCPNAK from any DHCP server that believes it is authoritative for the network's IP topology. .PP All the request packets sent by the program share the following common characteristics: .RS 5 .sp Ethernet Header .RS 5 destination: ff:ff:ff:ff:ff:ff .br source: .IR ether_src from .IR dhcp_probe.cf (5), else interface hardware address .br type: ETHERTYPE_IP (0x0800) .RE .sp IP Header .RS 5 version: 4 .br header length: 5 .br tos: 0 .br total length: 328 (20-byte IP header + 8-byte UDP header + 300-byte BootP/DHCP payload) .br identifier: 1 .br flags: 0 .br fragment offset: 0 .br ttl: 60 .br protocol: IPPROTO_UDP (17) .br header checksum: (computed) .br source address: 0.0.0.0 .br destination address: 255.255.255.255 .br options: (none) .RE .br .sp UDP Header .RS 5 source port: PORT_BOOTPC (68) .br dest port: PORT_BOOTPS (67) .br checksum: (computed) .RE .sp BootP/DHCP Payload .RS 5 op: BOOTREQUEST (1) .br htype: HTYPE_ETHER (1) .br hlen: HLEN_ETHER (6) .br hops: 0 .br xid: 1 .br secs: 0 .br flags: 0 .br ciaddr: 0.0.0.0 (except for DHCPREQUEST (REBINDING) packets it is .I client_ip_address from .BR dhcp_probe.cf (5), else 172.31.254.254) .br siaddr: 0.0.0.0 .br giaddr: 0.0.0.0 .br chaddr: .I chaddr from .IR dhcp_probe.cf (5), else interface hardware address .br sname: (all 0's) .br file: (all 0's) .br options: RFC1048 cookie (0x63825363), possibly followed by DHCP options, followed by END option (0xFF), followed by PAD options (0x00) to bring the field to 64 bytes .RE .RE .SH "MULTIPLE INTERFACES" Although dhcp_probe only supports monitoring a single physical or logical interface, you may run an instance of the program on each physical or logical interface; each monitors a different network. .PP When running multiple copies of dhcp_probe, be sure to specify a different .I pid_file for each instance. .PP If you specify a .I log_file and/or a .IR capture_file , be sure to specify a different one for each instance. .PP You may specify a different .I config_file for each instance. If you don't need to customize the settings in that file for each instance, you may use the same configuration file for all instances. .PP If you have multiple logical interfaces on the same VLAN on the same physical interface, or multiple logical IP networks on the same VLAN running on a single physical network, there is no need to run multiple instances of dhcp_probe to monitor each logical interface or logical network. A single instance of the program running on a physical interface or logical interface is sufficient to provoke any servers on that one VLAN on that physical (or logical) network that might be willing to respond. .PP If your physical interface supports 802.1Q, you can use a single physical interface to monitor multiple VLANs. Use your operating system to create a logical interface (on the same physical interface) for each VLAN. When frames arrive on the physical interface containing the 802.1Q tag you specified for the logical interface, your operating system is responsible for delivering those frames to the logical interface with the 802.1Q tag removed. (Some Ethernet drivers will retain the 802.1Q tag but change the VLAN ID to 0; we understand that format.) Run an instance of the program on each logical interface. If your operating system and network driver does not automatically add an 802.1Q header to the packets we transmit, you will also need to specify the \-Q option to instruct the program to add an 802.1Q header to the packets it constructs. (If the operating system or network driver automatically adds the 802.1Q header to these packets, then specifying \-Q will likely not do what you want. Selecting the wrong choice often means that the packets we construct will be transmitted incorrectly, or may be silently discarded by the operating system or the Ethernet switch.) .SH SIGNALS The program will respond to a number of signals: .TP .B SIGUSR1 If logging to a file, close and re-open it. If the program is in the middle of a probe cycle, handling the signal is deferred until the end of the cycle. (Has no effect if logging to .BR syslog (3) or if the .B \-f option was specified.) .TP .B SIGUSR2 If capturing to a file, close and re-open it. If the program is in the middle of a probe cycle, handling the signal is deferred until the end of the cycle. (Has no effect if the .B \-o option was not specified.) .sp Because re-opening the capture file causes the file to be truncated and a new .BR pcap (3) header to be written to it, if you want to save the prior contents of the capture file, move the existing capture file aside before sending the signal. .TP .B SIGHUP Reread the configuration file. If the program is in the middle of a probe cycle, handling the signal is deferred until the end of the cycle. .TP .B SIGTERM, SIGINT, SIGQUIT Exit gracefully. If the program is in the middle of a probe cycle, handling the signal is deferred until the program finishes sending and receiving responses for the current flavor request packet. .SH "LEASE NETWORKS OF CONCERN" Most rogue BootP/DHCP servers distribute private IP addresses to clients, or send DHCPNAK messages to legitimate clients. Some even more disruptive rogue BootP/DHCP servers may distribute IP addresses that fall within your own networks' IP ranges. The "Lease Networks of Concern" feature is intended to help you identify these particularly disruptive servers. .PP You may activate the feature by specifying the .B lease_network_of_concern statement in your configuration file. Use the statement multiple times to specify all your legitimate network ranges. .PP When a rogue BootP/DHCP server is detected, if the rogue's response packet contains a non-zero .B yiaddr value, the value is compared to the "Lease Networks of Concern" you specified. If the value falls within any of those network ranges, the message logged by .B dhcp_probe is extended to make note of this, and to report the .B yiaddr value. Furthermore, if you are using the .B alert_program_name2 feature, the alert program is called with an extra .B "\-y yiaddr" option so that alert program can take any additional action desired. .PP .SH "DEBUG LEVELS" The program produces increasingly detailed output as the .I debuglevel increases. Under normal circumstances, you can run at .IR debuglevel 0. Here's roughly what messages are added at each .IR debuglevel . .LP .TP 6 0 Display the IP source (and Ethernet source) of each unexpected DHCP or BootP response packet. .sp Startup and shutdown notice. .sp Non-fatal errors in the configuration file. .sp Fatal errors. .TP 6 1 At startup, show some information about the program's configuration. .TP 6 2 Show each time we start and finish (re-)reading the configuration file. .sp Show each time we close and re-open the logfile or capture file. .sp Report on response packets that could not be parsed (e.g. truncated). .TP 6 3 Each time we (re-)read the configuration file, echo the information we obtain from it. .TP 6 7 For each parsable response packet, show the Ethernet source and destination, the IP source and destination, and indicate when the IP source is a legal (known) server. .TP 6 11 For each probe cycle, show when the cycle begins and ends, when we write a packet, and when we begin and end listening for response packets. .SH AUTHOR The program was written by Irwin Tillman of Princeton University's OIT Network Systems Group. It was written to run on Solaris, relying on the generally-available .BR pcap (3) and .BR libnet (3) libraries. .SH FILES .TP .B /etc/dhcp_probe.cf Configuration file read by the program. See .BR dhcp_probe.cf (5). The name of this file can be overridden by a command-line option. .TP .B /etc/dhcp_probe.pid Contains the program's processid. The name of this file can be overriden by a command-line option. .SH LIMITATIONS dhcp_probe is not guaranteed to locate all unknown DHCP and BootP servers attached to a network. If a BootP server is configured so it only responds to certain clients (e.g. those with certain hardware addresses), it will not respond to the BOOTPREQUEST packet we sent. If a DHCP server is configured so it only responds to certain clients (e.g. those with certain hardware addresses or DHCP Client Identifiers), it will not respond to the packets we send that mimic DHCP clients in the INIT state. If a DHCP server is configured so it does not send DHCPNAK packets to clients requesting topologically-inappropriate IP addresses, it will not respond the packets we send that mimic DHCP clients in the INIT-REBOOT and REBINDING states. .PP The upshot is that it is possible that dhcp_probe will be unable to provoke some BootP and DHCP servers into responding at all. .PP Flushing out such servers can be extremely difficult. One approach is to capture all UDP/IP packet destined to the BootP client port which cross your network; since most of these packets are unicast at Layer 2, capturing is only effective if .I all such packets must pass by your capture device's Ethernet interface (e.g. the capture device is located at a network choke point, or the network does not involve any Layer 2 switching). Another approach is to do UDP port scanning for all devices listening on the BootP server port, and assume that those which are listening on that port are running a BootP or DHCP server. .PP Malicious BootP or DHCP servers that forge the IP source address (and possibly the Ethernet source address) of their responses to match the values specified by .B legal_server and .B legal_server_ethersrc statements will not be detected. .PP If the network contains any Ethernet switch which selectively filters (rather than floods) layer 2 broadcasts sent by DHCP/BootP clients, dhcp_probe will be unable to locate DHCP and BootP servers on the far side of that Ethernet switch. Such switches prevent the probe packets from reaching rogue DHCP/BootP servers. For example, some Cisco Nexus(R) switch/routers models configured to act as a network's IPv4 router and BootP Relay Agent may not flood such frames, instead delivering them only to the router's embedded BootP Relay Agent. .SH BUGS The packet capture buffer size is limited; if a single request packet provokes more responses than will fit into the buffer, those that do not fit are silently dropped, without any diagnostic indicating that the buffer was too small. You can adjust the size of the packet capture buffer size using the .BI \-s \ capture_bufsize option. .PP We do not support non-Ethernet interfaces. .PP Because (re-)opening a packet capture file causes the file to be opened for writing (not appending), the contents of any existing packet capture file of the same name is lost when the program starts or receives a SIGUSR2 signal. If the file's previous contents should be preserved, move the old file aside before starting the program or sending it a SIGUSR2 signal. (This "feature" exists because opening a .BR pcap (3) savefile always involves writing a pcap header record to the start of the file, so pcap always opens the file using mode "w".) .PP Because .BR pcap (3) opens the packet capture file with a simple .BR fopen (3) without checking to see if the file already exists, dhcp_probe may be tricked into overwriting or corrupting an existing file. As dhcp_probe is run with root privileges, this is a serious concern. To avoid this problem, if you use the .B \-o option, ensure that the directory that will contain the capture file is writable only by root. .PP The packet capture file that is written is unparseable after the first packet. E.g. if read with .BR tcpdump (8), it reports: .IR "tcpdump: pcap_loop: truncated dump file" . .PP On platforms where .BR pcap (3) is unable to support the .I timeout argument to .IR pcap_open_live , the program may not reliably detect responses from DHCP and BootP servers, or may not function at all. .SH "SEE ALSO" .LP .BR dhcp_probe.cf (5) .TP 10 .BR pcap (3) (a.k.a. libpcap, a packet capture library), available from http://www.tcpdump.org.

Each statement begins with a keyword followed by one or more arguments (depending on the keyword); keywords and arguments are separated by spaces or tabs. Statements may be specified in any order. .PP Some keywords take an .I ethernet-address argument. Ethernet address values must be written in a form that .BR ether_aton (3) recognizes; e.g. 1:2:3:4:5:6 or 00:A5:b2:0:BB:c. .PP Some keywords take an .I ip-address as a value. IP address values must be written in a form that .BR inet_aton (3) recognizes; e.g. 192.168.1.2. .PP Blank lines are ignored. Lines for which the first non-blank character is a '#' are treated as comments. Trailing comments on statements are .I not supported. .PP Because all presently-defined keywords are optional, the file may be empty, however, it must exist. .SH KEYWORDS .PP The keywords are as follows: .SS \fBchaddr\fP .RS .PP The .B chaddr statement is optional, and is used to specify the value of the .I chaddr field in the request packets sent by the program. This value is also used to compute the DHCP Client Identifier option in some of the request packets sent by the program (by prepending x'01'). .PP Specify: .IP chaddr .I ethernet-address .PP If not specified, this value defaults to the Ethernet address corresponding to the interface you specified on the commandline. .PP You might want to use the .B chaddr statement if the interface is also a DHCP client, so that sending requests with the interface's own chaddr/DHCP Client Identifier will not interfere with that functionality. .PP If you specify a value, be sure to specify a unicast Ethernet address that does not belong to any valid client on your network. .PP Correctly-functioning BootP and DHCP servers that respond will send any responses to the .I chaddr address, or in some cases, to the Ethernet broadcast address. Therefore, if you specify a value here (and it differs from your interface's Ethernet address), the program will have to place the interface into promiscuous mode to be sure it hears unicast responses. .PP Note that the .I chaddr value does not affect the Ethernet source address of the Ethernet frames sent by the program. .PP If you specify this value, you may also wish to specify the same value in the .B ether_src statement. See the description of that statement for further discussion. .PP The .B chaddr statement is required if .B do_not_lookup_enet_and_ip_addresses is specified. .SS \fBether_src\fP .RS .PP The .B ether_src statement is optional, and is used to specify the value of the .I ether_src field in the Ethernet frames sent by the program. .PP Specify: .IP ether_src .I ethernet-address .PP If not specified, this value defaults to the Ethernet address corresponding to the interface you specified on the commandline. .PP If you specify a value, be sure to specify a unicast Ethernet address that does not belong to any valid client on your network. .PP Note that this value does not affect the .I chaddr field or the DHCP Client Identifier option field in request packets sent by the program. .PP If you specified a .I chaddr value, you may also wish to specify an equal .I ether_src value. While not strictly necessary, doing so will cause any Layer 2 switches on the network to learn that this hardware address is on your leg of the network, so they will not need to flood response packets directed to that hardware address, but instead can direct the response packets only to your leg of the network. .PP Additionally, specifying the same .I ether_src value could help you discover any buggy BootP or DHCP servers that mistakenly direct their responses to the sender's ether_src (instead of to the sender's bootp_chaddr). .PP The .B ether_src statement is required if .B do_not_lookup_enet_and_ip_addresses is specified. .SS \fBdo_not_lookup_enet_and_ip_addresses\fP .RS .PP The .B do_not_lookup_enet_and_ip_addresses statement is optional. When not specified, the program will try to look up the Ethernet address of the network interface specified on the commandline. (It does so by querying the operating system for this information.) In order to do so, it may need to first look up the IP address of the network interface specified on the commandline. Performing either operation may be troublesome on some interfaces or platforms. Failure of these lookups is a fatal error. .PP Specifying .B do_not_lookup_enet_and_ip_addresses instructs the program to not try to look up the interface's Ethernet address and IP address. .PP If .B do_not_lookup_enet_and_ip_addresses is specified, then both .B ether_src and .B chaddr must be specified. .PP Specifying .B do_not_lookup_enet_and_ip_addresses may allow use of this program on interfaces configured with no IP address. .SS \fBserver_id\fP .RS .PP The .B server_id statement is optional, and is used to specify the value of the DHCP Server Identifer option in some of the request packets sent by the program. .PP Specify: .IP server_id .I ip-address .PP If not specified, this value defaults to 10.254.254.254. .PP The DHCP Server Identifer option appears in the packets the program sends when it mimics a DHCP client in the SELECTING state. .PP It's best that the DHCP Server Identifier option the program uses not match the IP address of any valid DHCP server on your network, to avoid confusing them. Other than that, any IP address is a reasonable value; you may wish to specify one that could never be a valid address on your network. .SS \fBclient_ip_address\fP .RS .PP The .B client_ip_address statement is optional, and is used to specify the IP address that the program should request, or claim to have a lease on. .PP Specify: .IP client_ip_address .I ip-address .PP If not specified, this value defaults to 172.31.254.254. .PP When the program generates a DHCPREQUEST packet that mimics a DHCP client that is in the INIT-REBOOT or SELECTING state, the packet contains a Requested IP Address option containing this value. When the program generates a DHCPREQUEST packet that mimics a DHCP client that is in the REBINDING state, the packet contains a .I ciaddr field containing this value. .PP It's best that the value the program uses not match the IP address of any valid DHCP client on your network, to avoid confusing valid DHCP servers. .PP It's extremely useful if the value the program uses .I not be valid (topologically speaking) for the physical network on which the program sends the packets. Sending a topologically inappropriate value may stimulate some DHCP servers to respond with a DHCPNAK, which helps the program flush out DHCP servers. .SS \fBresponse_wait_time\fP .RS .PP The .B response_wait_time statement is optional, and is used to specify how long the program should wait for responses after sending a single request packet. .PP Specify .IP response_wait_time .I num_milliseconds .PP If not specified, this value defaults to 5000 milliseconds (5 seconds). .PP The value is specified in milliseconds, and must fit into an 'int' on your host. (Values larger than an 'int' may be silently misinterpreted.) Typical values are on the order of a few thousand milliseconds; i.e. several seconds. .SS \fBcycle_time\fP .RS .PP The .B cycle_time statement is optional, and is used to specify how long the program should sleep between each probe cycle. .PP Specify .IP cycle_time .I num_seconds .PP If not specified, this value defaults to 300 seconds. .PP The value is specified in seconds, and must into into an 'unsigned int' on your host. (Values larger than an 'unsigned int' may be silently misinterpreted.) Typical valus range from several hundred to several thousand seconds (i.e. several minutes to several hours). .PP During each probe cycle, the program sends one of the request packet flavors, captures any responses that arrive during the .IR response_wait_time , then repeats this for each of the other request packet flavors. After doing this for each flavor of request packet, the probe cycle is complete, and the program sleeps for the .IR cycle_time . .SS \fBlegal_server\fP .RS .PP The .B legal_server statement is optional, and is used to specify the IP source address of responses that come from a legal BootP or DHCP server on your network. The statement may be specified multiple times. .PP Specify .IP legal_server .I ip-address .PP If not specified, the program assumes there are no legal BootP and DHCP servers on your network; all responses will be treated as coming from an unknown DHCP server. .PP When the program receives a response packet, it compares the packet's IP source address to all the addresses you have specified in .B legal_server statements. If the IP source address matches one of these values, the response is deemed to have come from a known DHCP server, and is ignored. If the IP source address does not match any of these values (or you do not specify any .BR legal_server ), then the program logs a message that reports the packet's IP source address and Ethernet source address. Additionally, if the program was started with the .B \-o commandline option, the packet is also written to a packet capture file. .PP If both .B legal_server and .B legal_server_ethersrc statements appear, then a response must have both a valid IP source and a valid ethernet source to be considered to have come from a known DHCP server. .PP When relaying a response from a server to a client, some BootP Relay Agents may change the response's IP source address, replacing the server's IP address with that of the BootP Relay Agent. If BootP Relay Agents on your network do this, you will need to specify their IP addresses here instead. .SS \fBlegal_server_ethersrc\fP .RS .PP The .B legal_server_ethersrc statement is optional, and is used to specify the Ethernet source address of responses that come from a legal BootP or DHCP server on your network. The statement may be specified multiple times. .PP Specify .IP legal_server_ethersrc .I ethernet-address .PP If not specified, the program does not check the Ethernet source address of responses. .PP If you have specified at least one .B legal_server_ethersrc value, when the program receives a response packet, the program compares the packet's Ethernet source address to all the addresses you have specified in .B legal_server_ethersrc statements. If the Ethernet source does not match one of these values, the response is deemed to have come from an unknown DHCP server; the program logs a message that reports the packet's IP source address and Ethernet source address. Additionally, if the program was started with the .B \-o commandline option, the packet is also written to a packet capture file. .PP If both .B legal_server and .B legal_server_ethersrc statements appear, then a response must have both a valid IP source and a valid ethernet source to be considered to have come from a known DHCP server. .PP Each router on the path from the DHCP server to the DHCP client will overwrite the Ethernet source address field. So if you specify any .B legal_server_ethersrc statements, also list the Ethernet source value(s) for the last hop router(s). A BootP Relay Agent on the path from the DHCP server to the DHCP client will overwrite the Ethernet field. So also list the Ethernet source value(s) for the BootP Relay Agent. (The BootP Relay Agent is often co-resident in the last-hop IP router, so you may have already taken care of this when you listed the last-hop router(s). .PP The .B legal_server_ethersrc statement is considered experimental in versions 1.3.0 - 1.3.1, as it has received only limited testing. .SS \fBlease_network_of_concern\fP .RS .PP The .B lease_network_of_concern statement is optional, and may be specified multiple times. The statement is used to specify one or more network ranges that are of concern relative to the IP addresses distributed by a rogue BootP/DHCP server. .PP Specify .IP lease_network_of_concern .I network-ip-address network-mask .PP Specifying one or more .B lease_network_of_concern statements activates the "Lease Networks of Concern" feature. .PP When the program receives a response packet that it determines to be from a rogue BootP/DHCP server, if the "Lease Networks of Concern" feature is active, the program will examine the packet further. If the packet's .B yiaddr field is non-zero, the value in that field is tested to see if it falls within any of the "Leases Networks of Concern." If it does, then the message the program logs is extended to also report this fact, and to include the value of the .B yiaddr field. Furthermore, if an .B alert_program_name2 was specified, when that program is called, it is called with an additional .B "\-y yiaddr" option. (This is not supported if an .B alert_program_name was specified, as the older .B alert_program_name uses a syntax that cannot be extended.) .PP The "Lease Networks of Concern" feature does not change the way the program probes for or detects rogue BootP/DHCP servers. Upon detection of a rogue BootP/DHCP server, the feature only may cause additional information to be added to the message logged (and passed to .BR alert_program_name2 ). .PP This feature may be used, for example, by specifying your networks' legitimate address ranges as "Lease Networks of Concern". While most rogue BootP/DHCP servers distribute private IP addresses, or send DHCPNAKs to legitimate clients, other more damaging rogue BootP/DHCP servers may distribute IP addresses that fall within your legitimate network ranges. This will help differentiate those more damaging incidents from the more common ones. .SS \fBalert_program_name\fP .RS .PP The .B alert_program_name statement is optional, and may be used to specify the name of an external program that should be run every time a response packet is received from an unexpected server. .PP Note that using the newer .B alert_program_name2 statement is preferrable. .PP Specify .IP alert_program_name .I /absolute/path/name .PP Unexpected response packets are reported as a matter of course, and optionally written to a packet capture file. You may use an .B alert_program_name to provide additional handling of the event, for example, to alert an appropriate party via mail or paging. The .B alert_program_name you specify is called with four arguments in the following order: the name of the calling program (e.g. .BR dhcp_probe ), the name of the interface on which the unexpected response packet was received, the IP source address of the packet, and the Ethernet source address of the packet. .PP As the .B alert_program_name is called with the same privileges as .B dhcp_probe (i.e. root), you should exercise caution to ensure that the alert program is safe for a privileged user to execute. .PP Because the syntax supported by the external program is not extensible, the use of .B alert_program_name2 is preferrable. .PP You may not specify both .B alert_program_name and .BR alert_program_name2 . .SS \fBalert_program_name2\fP .RS .PP The .B alert_program_name2 statement is optional, and may be used to specify the name of an external program that should be run every time a response packet is received from an unexpected server. .PP Specify .IP alert_program_name2 .I /absolute/path/name .PP Unexpected response packets are reported as a matter of course, and optionally written to a packet capture file. You may use an .B alert_program_name2 to provide additional handling of the event, for example, to alert an appropriate party via mail or paging. The .B alert_program_name2 you specify is called with the following required options: .PP .RS .nf \-p the name of the calling program (e.g. dhcp_probe), \-I the name of the interface on which the unexpected response packet was received \-i the IP source address of the packet \-m Ethernet source address of the packet .fi .RE .PP The following non-required options may also be passed: .PP .RS .nf \-y the non-zero yiaddr value from the packet, when it falls inside a "Lease Network of Concern" .fi .RE .PP The .B alert_program_name2 program you specify must ignore options or arguments it does not recognize; this is to ensure it remains forward-compatible with future enhancements to .BR dhcp_probe . It must be prepared to accept options in any order. .PP As the .B alert_program_name2 is called with the same privileges as .B dhcp_probe (i.e. root), you should exercise caution to ensure that the alert program is safe for a privileged user to execute. .PP You may not specify both .B alert_program_name and .BR alert_program_name2 . .RE .SH EXAMPLE An example .B /etc/dhcp_probe.cf file follows: .PP .RS .nf # dhcp_probe.cf: config file for dhcp_probe # # General syntax: # Comment lines start with '#' (trailing comments not permitted). # Blank lines are OK. # Tokens within a line should be separated with spaces and/or tabs. # Entries in the file may be in any order. # Any 'ethernet-address' must be written in a form that ether_aton(3) recognizes; e.g. # 1:2:3:4:5:6 00:A5:b2:0:BB:c # Any 'ip-address' must be written in a form that inet_aton(3) recognizes; e.g. # 192.168.1.2 # # ---------------------------------------------------------------------------------- # # CLIENT HARDWARE ADDRESS # # By default, for the 'chaddr' field in the BootP header, we use the Ethernet # address corresponding to the interface you specified. # We also use this value to compute the DHCP Client Identifier option (by prepending x'01'). # You may optionally override this value. # (Note that this does not override the Ethernet Src address in the Ethernet frame we send.) # # You might want to do this if our interface is also a DHCP client, so # sending requests with the interface's own chaddr/DHCP Client Identifier would interfere with # that functionality. # # If you specify a value, be sure to specify an Ethernet address that does not belong to # any valid client on your network.
