By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets are taking to reach the destination. .P The problem is that with the widespread use of firewalls on the modern Internet, many of the packets that .IR traceroute (8) sends out end up being filtered, making it impossible to completely trace the path to the destination. However, in many cases, these firewalls will permit inbound TCP packets to specific ports that hosts sitting behind the firewall are listening for connections on. By sending out TCP SYN packets instead of UDP or ICMP ECHO packets, .B tcptraceroute is able to bypass the most common firewall filters. .P It is worth noting that .B tcptraceroute never completely establishes a TCP connection with the destination host. If the host is not listening for incoming connections, it will respond with an RST indicating that the port is closed. If the host instead responds with a SYN|ACK, the port is known to be open, and an RST is sent by the kernel .B tcptraceroute is running on to tear down the connection without completing three\-way handshake. This is the same half\-open scanning technique that .IR nmap (1) uses when passed the .BR \-sS flag. .SH OPTIONS .B .IP \-n Display numeric output, rather than doing a reverse DNS lookup for each hop. By default, reverse lookups are never attempted on RFC1918 address space, regardless of the \-n flag. .B .IP \-N Perform a reverse DNS lookup for each hop, including RFC1918 addresses. .B .IP \-f Set the initial TTL used in the first outgoing packet. The default is 1. .B .IP \-m Set the maximum TTL used in outgoing packets. The default is 30. .B .IP \-p Use the specified local TCP port in outgoing packets. The default is to obtain a free port from the kernel using .IR bind (2). Unlike with traditional .IR traceroute (8), this number will not increase with each hop. .B .IP \-s Set the source address for outgoing packets. See also the \-i flag. .B .IP \-i Use the specified interface for outgoing packets. .B .IP \-q Set the number of probes to be sent to each hop. The default is 3. .B .IP \-w Set the timeout, in seconds, to wait for a response for each probe. The default is 3. .B .IP \-S Set the TCP SYN flag in outgoing packets. This is the default, if neither \-S or \-A is specified. .B .B .IP \-A Set the TCP ACK flag in outgoing packets. By doing so, it is possible to trace through stateless firewalls which permit outgoing TCP connections. .B .IP \-E Send ECN SYN packets, as described in RFC2481. .B .IP \-t Set the IP TOS (type of service) to be used in outgoing packets. The default is not to set any TOS. .B .IP \-F Set the IP "don't fragment" bit in outgoing packets. .B .IP \-l Set the total packet length to be used in outgoing packets. If the length is greater than the minimum size required to assemble the necessary probe packet headers, this value is automatically increased. .B .IP \-d Enable debugging, which may or may not be useful. .B .IP \-\-dnat .br Enable DNAT detection, and display messages when DNAT transitions are observed. DNAT detection is based on the fact that some NAT devices, such as some Linux 2.4 kernels, do not correctly rewrite the IP address of the IP packets quoted in ICMP time-exceeded messages tcptraceroute solicits, revealing the destination IP address an outbound probe packet was NATed to. NAT devices which correctly rewrite the IP address quoted by ICMP messages, such as some Linux 2.6 kernels, will not be detected. For some target hosts, it may be necessary to use \-\-dnat in conjunction with \-\-track\-port. See the examples.txt file for examples. .B .IP \-\-no-dnat .br Enable DNAT detection for the purposes of correctly identifying ICMP time-exceeded messages that match up with outbound probe packets, but do not display messages when a DNAT transition is observed. This is the default behavior. .B .IP \-\-no-dnat-strict .br Do not perform any DNAT detection whatsoever. No attempt will be made match up ICMP time-exceeded messages with outbound probe packets, and when tracerouting through a NAT device which does not rewrite the IP addresses of the IP packets quoted in ICMP time-exceeded messages, some hops along the path may appear to be unresponsive. This option should not be needed in the vast majority of cases, but may be utilized if it is suspected that the DNAT detection code is misidentifying ICMP time-exceeded messages. .SH EXAMPLES Please see the .I examples.txt file included in the .B tcptraceroute distribution for a few real world examples. .P To trace the path to a web server listening for connections on port 80: .P .RS .B tcptraceroute webserver .RE .P To trace the path to a mail server listening for connections on port 25: .P .RS .B tcptraceroute mailserver 25 .RE .SH BUGS No error checking is performed on the source address specified by the \-s flag, and it is therefore possible for .B tcptraceroute to send out TCP SYN packets for which it has no chance of seeing a response to. .SH AUTHOR Michael C.

DESCRIPTION


tcptraceroute

is a traceroute implementation using TCP packets.

The more traditional
traceroute(8)

sends out either UDP or ICMP ECHO packets with a TTL of one, and increments
the TTL until the destination has been reached.  By printing the gateways that
generate ICMP time exceeded messages along the way, it is able to determine the
path packets are taking to reach the destination.



The problem is that with the widespread use of firewalls on the modern
Internet, many of the packets that
traceroute(8)
sends out end up being filtered, making it impossible to completely trace the
path to the destination.  However, in many cases, these firewalls will permit
inbound TCP packets to specific ports that hosts sitting behind the
firewall are listening for connections on.  By sending out TCP SYN packets
instead of UDP or ICMP ECHO packets,
tcptraceroute
is able to bypass the most common firewall filters.



It is worth noting that 
tcptraceroute

never completely establishes a TCP connection with the destination host.
If the host is not listening for incoming connections, it will respond with
an RST indicating that the port is closed.  If the host instead responds
with a SYN|ACK, the port is known to be open, and an RST is sent by the
kernel
tcptraceroute

is running on to tear down the connection without completing
three-way handshake.  This is the same half-open scanning technique
that
nmap(1)

uses when passed the
-sS

flag.
 

OPTIONS





-n



Display numeric output, rather than doing a reverse DNS lookup for each hop.
By default, reverse lookups are never attempted on RFC1918 address space,
regardless of the -n flag.

-N



Perform a reverse DNS lookup for each hop, including RFC1918 addresses.

-f



Set the initial TTL used in the first outgoing packet.  The default is 1.

-m



Set the maximum TTL used in outgoing packets.  The default is 30.

-p



Use the specified local TCP port in outgoing packets.  The default is to
obtain a free port from the kernel using
>bind(2).

Unlike with traditional
traceroute(8),

this number will not increase with each hop.

-s



Set the source address for outgoing packets.  See also the -i flag.

-i



Use the specified interface for outgoing packets.

-q



Set the number of probes to be sent to each hop.  The default is 3.

-w



Set the timeout, in seconds, to wait for a response for each probe.  The
default is 3.

-S



Set the TCP SYN flag in outgoing packets.  This is the default, if neither
-S or -A is specified.

-A





Set the TCP ACK flag in outgoing packets.  By doing so, it is possible to
trace through stateless firewalls which permit outgoing TCP connections.

-E



Send ECN SYN packets, as described in RFC2481.

-t



Set the IP TOS (type of service) to be used in outgoing packets.  The
default is not to set any TOS.

-F



Set the IP "don't fragment" bit in outgoing packets.

-l



Set the total packet length to be used in outgoing packets.  If the length
is greater than the minimum size required to assemble the necessary probe
packet headers, this value is automatically increased.

-d


Enable debugging, which may or may not be useful.




--dnat




Enable DNAT detection, and display messages when DNAT transitions are
observed.  DNAT detection is based on the fact that some NAT devices,
such as some Linux 2.4 kernels, do not correctly rewrite the IP address
of the IP packets quoted in ICMP time-exceeded messages
tcptraceroute solicits, revealing the destination IP address an outbound
probe packet was NATed to.  NAT devices which correctly rewrite the IP
address quoted by ICMP messages, such as some Linux 2.6 kernels, will
not be detected.  For some target hosts, it may be necessary to use
--dnat in conjunction with --track-port.  See the examples.txt file for
examples.




--no-dnat



Enable DNAT detection for the purposes of correctly identifying ICMP
time-exceeded messages that match up with outbound probe packets, but
do not display messages when a DNAT transition is observed.  This is
the default behavior.




--no-dnat-strict



Do not perform any DNAT detection whatsoever.  No attempt will be made
match up ICMP time-exceeded messages with outbound probe packets, and
when tracerouting through a NAT device which does not rewrite the IP
addresses of the IP packets quoted in ICMP time-exceeded messages, some
hops along the path may appear to be unresponsive.  This option should
not be needed in the vast majority of cases, but may be utilized if
it is suspected that the DNAT detection code is misidentifying ICMP
time-exceeded messages.





 

EXAMPLES


Please see the
examples.txt

file included in the
tcptraceroute

distribution for a few real world examples.

To trace the path to a web server listening for connections on port 80:



tcptraceroute webserver





To trace the path to a mail server listening for connections on port 25:



tcptraceroute mailserver 25




 

BUGS


No error checking is performed on the source address specified by the -s
flag, and it is therefore possible for 
tcptraceroute

to send out TCP SYN packets for which it has no chance of seeing a response
to.

task of installation and to provide better portability.  As with all
programs utilizing autoconf, the simplest way to compile the package is
(quoting from the default INSTALL documentation that ships with
autoconf):

  1. `cd' to the directory containing the package's source code and type
     `./configure' to configure the package for your system.  If you're
     using `csh' on an old version of System V, you might need to type
     `sh ./configure' instead to prevent `csh' from trying to execute
     `configure' itself.

     Running `configure' takes awhile.  While running, it prints some
     messages telling which features it is checking for.

  2. Type `make' to compile the package.

  3. Type `make install' to install the programs and any data files and
     documentation.

  4. 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'.

The configure scripts supports a number of command line options.  The
ones you're most likely to use are:

	  --prefix=PREFIX         install architecture-independent files in
                                  PREFIX [/usr/local]
	  --with-libpcap=DIR      use libpcap in DIR
	  --with-libnet=DIR       use libnet in DIR
	  --enable-noselect-default
				  default to not using select(2)
	  --enable-track-default=PORT|ID
				  default to tracking probes by PORT or ID
	  --enable-default-port=N default destination port

firewalls that traceroute(8) has trouble with.  These are all sites
that pass TCP SYN packets on to hosts sitting on the clean side of the
firewall, and which don't filter ICMP time exceeded messages leaving
their network.  All examples listed below were captured on July 1st.

tcptraceroute-1.3beta1 added support for controlling the SYN and ACK
flags used in outgoing probe packets through the -S and -A command line
arguments.  By utilizing probe packets with the ACK bit set, it is
possible to traceroute to hosts located behind stateless firewalls that
block all inbound TCP connections, but permit those hosts to establish
outbound connections.  Below are two examples of such behavior,
recorded on August 15th, 2001.

tcptraceroute-1.5beta6 added the --dnat detection support, to detect
DNAT devices which do not correctly rewrite the IP address of the IP
packets quoted in ICMP time-exceeded messages tcptraceroute solicits,
revealing the destination IP address an outbound probe packet was NATed
to.  Below are examples of using --dnat to determine the IP address our
probe packets are being NATed to, recorded on March 28th, 2006.

    Added check to ensure pcap_fd is within the range of select(2) to
    avoid any potential FD_SET overflows, by Shaun Colley 

    Rebuilt autoconf files with a more recent version of autoconf from a
    Debian Sarge system, to resolve Debian Bug#333827.

    Updated the man page and examples.txt files to document the new --dnat
    detection features.

    Updated the (unofficial) debian/control file to build-depend on
    libnet1-dev rather than libnet0-dev.

Version 1.5beta6 (2005-01-03)

    New --dnat, --no-dnat (default), and --no-dnat-strict command line
    arguments.  --dnat enabled Destination NAT detection, which works by
    comparing the quoted IP address in an ICMP payload with the
    destination a probe packet was addressed to.

    Numeric IP address in parenthesis is now only displayed if the content
    in the parenthesis is different than the non-parenthesized content,
    making the output less busy.

    The SYN ISN (Initial Sequence Number) now set to a random 32bit value;
    previously had always been zero.

    Added missing htons() call around the arguments to getservbyport(),
    which resulted in the destination port service name not being correctly
    reported on some architectures, by Dmitry Karasik 

    Improved the configure.ac so that it is less likely to link against
    unnecessary libraries by "Dmitry V. Levin" 

    --no-select is now the default under NetBSD, based on a report and data
    collected by Ed Ravin .

    Split the tcptraceroute.c file into main.c, datalink.c, probe.c,
    capture.c, util.c, and a number of include files, which should make
    things much more manageable.

Version 1.5beta5 (2003-07-02)

    Now functions properly with libpcap when using an interface without a
    valid IPv4 addresss.  Reported by Kris Shannon 
    in Debian Bug#183456.

    Improved autoconf handling of the --with-libpcap= command line argument,
    by Richard van den Berg .

    Moved the tcptraceroute man page to section 1 from section 8 now that
    tcptraceroute is installed in /usr/bin by default, as suggested by
    James Ralston .

    Added a missing call to pcap_freecode() to free up memory utilized
    by the bpf_program struct, after applying it with pcap_setfilter().

    Should now deal better (and skip over) unconfigured interface under
    NetBSD.

Version 1.5beta4 (2003-06-29)

    A call to seteuid() has been replaced with a call to setuid() to fully
    drop root privileges.  As there are currently no known exploitable
    portions of tcptraceroute, older versions are still believed to be
    safe even without fully dropping privileges, however users are still
    encouraged to upgrade to provide a measure of containment in the event
    that an exploitable flaw is discovered in the future.  Reported by Matt
    Zimmerman , and published in Debian Security Advisory
    DSA 330-1.

    AC_FUNC_REALLOC was commented out of configure.ac, which was failing on
    HP/UX badly systems.  The xrealloc() function in tcptraceroute already
    works around the realloc(0,0) case that AC_FUNC_REALLOC is attempting
    to prevent against, anyway.  Reported by Petter Reinholdtsen
    .

Version 1.5beta3 (2003-06-01)

    Added some additional AC_CHECK_LIB lines to the configure.ac file,
    required for Solaris systems, by Petter Reinholdtsen .

    Fixed a number of type warnings under non-gcc compilers by adding a few
    casts; reported by Petter Reinholdtsen .

Version 1.5beta2 (2003-05-25)

    Added an autoconf check to detect MacOS X systems by looking to see if
    __APPLE__ and __MACH__ are defined.  Also added an autoconf configure
    command line argument --enable-noselect-default to control the default
    behavior of the tcptraceroute --noselect command line argument, and
    enabled it by default on MacOS X systems if not otherwise specified.

Version 1.5beta1 (2003-05-24)

    Most substantially, support for both autoconf and libnet-1.1.x
    has been added, based on patches from (in alphabetical order):

        jbash@velvet.com
        Jon Allen Boone 
        James Ralston 
        Darren Tucker 
        Matt Weidner 
    
    Added linklayer support for PPPoE interfaces, by Darren Tucker
    .

    Improved the round trip time calculations, by Amgad Zeitoun
    .

    Removed a number of multi-line strings, which apparently causes
    trouble for some compilers, based on patches from:

        jbash@velvet.com
        Richard van den Berg 
        Petter Reinholdtsen 

Version 1.4 (2002-07-30)

    Added linklayer support for Linux ISDN Sync-PPP interfaces,
    by Dr. Peter Bieringer .

    Adds support back for DLT_RAW interfaces, which was inadvertently
    removed sometime between 1.2 and 1.3beta1, and as a result caused
    tcptraceroute to fail over PPP interfaces.  Reported in Debian
    Bug#154793 by David Harris .

Version 1.3 (2002-05-19)

    Now detects (and ignores) IP packets with IP options.

    Packets are now properly aligned by allocating new space and
    copying the packet data there before casting packet header
    structs against them.

    New, undocumented --no-select command line argument added to never
    call select(), which fails to indicate that a BPF socket is ready
    for reading on some BSD systems.

    Now sets a non-zero exit code if the destination was not reached,
    as suggested by Arndt Schoenewald 

    Fixes an off-by-one error in getinterfaces(), discovered by
    Kit Knox .

    probe() and capture() now use a new proberecord structure which
    contains information about each probe in a modularized way.

    Added a new command line argument, --track-port, which causes each
    probe to have a unique source port so that something other than the
    IP ID can be used to track it, and also a corresponding --track-id
    argument to specify the old behavior of tracking IP ID's.  If a
    source port is specified with -p, --track-id is implied.  The
    compile-time default on Solaris is --track-port, enabling
    tcptraceroute to work out-of-the-box, and --track-id on all other
    platforms.

    probe() now calls allocateid() to generate an IP ID, which
    caches the last ALLOCATEID_CACHE_SIZE allocations to prevent
    against duplicates.

    Display "!" instead of "!?" for unknown ICMP codes, as
    suggested by Kevin McAllister 

    Attempts to find virtual addresses under OpenBSD, based on a
    patch by Scott Gifford 

    Moves the datalinkoffset and datalinkname information into a
    single data structure, which is much more logical, and less
    prone to error.

    Improved command line argument handling a good deal, based
    on suggestions by Scott Fenton .  First,
    a pass through is made to process and shift out long command
    line arguments, then the remaining command line is passed to
    getopt().

    It is now possible to traceroute to yourself, by switching the
    device to the loopback interface if the destination matches the
    address of a local interface.  Additionally, as learned by
    looking through the nmap source, we now never set a libpcap
    filter on the loopback interface to avoid apparent libpcap bugs
    which previously made it impossible to traceroute to 127.0.0.1

    Added -S and -A command line arguments to control the SYN
    and ACK flags in outgoing packets.  By using -A, it is now
    possible to traceroute through stateless firewalls which
    permit hosts behind the firewalls to establish outgoing TCP
    connections.  In the absence of either -A or -S, -S is set.

    Added -N command line argument which takes the place of the
    previous RESOLVE_RFC1918 #define.

    Now displays if the remote host is ECN capable when using -E

Version 1.2 (2001-07-31)

    Contains large portions of code and ideas contributed by
    Scott Gifford 

    Attempt to determine what outgoing interface to use based on
    the destination address and the local system's interface list.
    Could still use a good deal of work on BSD systems, though,
    especially when it comes to virtual addresses which reside on
    subnets different than the primary address.
    
    The timeout code has been reworked significantly, and should
    now be much more reliable.
    
    Added -E command line argument to send ECN (RFC2481) packets.
    Requested by Christophe Barb  and
    Jim Penny 

    Added -l command line argument to set the total packet length,
    including IP header.
    
    Added support for sending more than one probe to each hop, and
    the -q command line option to specify the number of probes.
    
    Added -F command line argument to set the IP_DF bit.
    
    Added -t command line argument to set the IP TOS.
    
    Now properly checks the length of the packets returned by libpcap
    before blindly assuming that the entire header structure we happen
    to be looking for is there.  This could have been very ugly had the
    snaplen not been set so conservatively.
    
    Print banner information to stderr, not stdout, to be compatible with
    traceroute(8).  Reported by Scott Fenton 

    Fixed an endian bug reported by Zoran Dzelajlija ,
    which prevented users from specifying the destination port number by
    name.

Version 1.1 (2001-06-30)

    Now drops root privileges after sockets have been opened.

    Must now be root to use -s or -p, making it now safe to to install
    tcptraceroute suid root, without fear that users can generate arbitrary
    SYN packets.

Version 1.0 (2001-04-10)

    Initial Release.

\`configure' configures this package to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
			  [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
			  [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR           user executables [EPREFIX/bin]
  --sbindir=DIR          system admin executables [EPREFIX/sbin]
  --libexecdir=DIR       program executables [EPREFIX/libexec]
  --datadir=DIR          read-only architecture-independent data [PREFIX/share]
  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
  --libdir=DIR           object code libraries [EPREFIX/lib]
  --includedir=DIR       C header files [PREFIX/include]
  --oldincludedir=DIR    C header files for non-gcc [/usr/include]
  --infodir=DIR          info documentation [PREFIX/info]
  --mandir=DIR           man documentation [PREFIX/man]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]
  --target=TARGET   configure for building compilers for TARGET [HOST]

Optional Features:
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-noselect-default
                          default to not using select(2)
  --enable-track-default=PORT|ID
                          default to tracking probes by PORT or ID
  --enable-default-port=N default destination port
  --enable-static         compile staticly, if using gcc

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)

  --with-libpcap=DIR      use libpcap in DIR
  --with-libnet=DIR       use libnet in DIR

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L if you have libraries in a
              nonstandard directory 
  CPPFLAGS    C/C++ preprocessor flags, e.g. -I if you have
              headers in a nonstandard directory 
  CPP         C preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

		       Version 2, June 1991

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

			    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.

	    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)   

    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., 59 Temple Place, Suite 330, Boston, MA  02111-1307  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) year  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.
