It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC to any special C compiler that is needed for # multi-threaded programs (defaults to the value of CC otherwise). (This # is necessary on AIX to use the special cc_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also link it with them as well. e.g. you should link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threads programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name # (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # LICENSE # # Copyright (c) 2008 Steven G.

In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. 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 $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

In inetd mode, the configuration file is parsed every time .B tac_plus starts. .sp If the configuration is large or the frequency of connections is high, this negatively will affect the responsiveness of the daemon. .sp If the config file is small, connections are infrequent, and authentication is being done via passwd(5) files or SKEY (which are not cached), running in inetd mode should be tolerable, but still is not recommended. .sp This option does not work with single-connection sessions. .\" .TP .B -l Specify an alternate log file location.

Tac_plus will background itself and start listening on port 49 for incoming tcp connections. .sp Tac_plus must be invoked as root to obtain privileged network socket 49 and to read the protected configuration file, which may contain confidential information such as encryption keys and cleartext passwords. .sp After the port is acquired and the config file is read, root privileges are no longer required. You can arrange that tac_plus will change its user and group IDs to a more innocuous user and group via the configuration file. .sp NOTE: The new user and group still needs permission to read any passwd(5) (and shadow(5)) files and S/KEY database if these are being used. .\" .SH "TCP WRAPPERS" If .B tac_plus was compiled with libwrap (aka. tcp_wrappers) support, upon connection the daemon will consult with tcp_wrappers on whether the client has permission to connect. The daemon name used in a daemon list of the access control file is the name of the executable, normally "tac_plus". See .BR hosts_access (5). .\" .SH PERMISSIONS The configuration file should be unreadable and unwriteable by anyone except root, as it contains passwords and keys. .\" .SH SIGNALS If the daemon is receives a SIGHUP or SIGUSR1, it will reinitialize itself and re-read its configuration file. .sp Note: if an error is encountered in the configuration file or the file can not be opened for reading, such as due to insufficient permissions resulting from process ownership and file permissions, the daemon will exit. .sp Likewise, if the daemon is configured to send accounting records to a file and that file can not be opened for writing, such as due to insufficient permissions resulting from process ownership and file permissions, the daemon will exit. .\" .SH "LOG MESSAGES" .B tac_plus logs error and informational messages to syslog facility LOG_DAEMON. .\" .SH FILES .TP 30 .B @TACPLUS_ACCTFILE@ Default accounting file. .\" .TP .B @TACPLUS_LOGFILE@ Default log file used when the .B \-d option is used. .\" .TP .B @TACPLUS_PIDFILE@ Pid file.

Made available at no cost and with no warranty of any kind. See the file COPYING and source files that came with the distribution for specifics. .sp Though heavily modified from the original Cisco manual pages, much of the modifications are derived from the tacacs IETF draft and the Cisco user guide. tacacs+-F4.0.4.27a/tac_plus.conf.5.in100644 015615 000000 00000137567 12177474702 0012507.\" .hys 50 .TH tac_plus.conf 5 "1 August 2013" .\" .SH NAME .\" tac_plus.conf \- tacacs+ daemon configuration file .\" .SH DESCRIPTION .\" This page is a work in progress. .PP .B tac_plus.conf contains configuration information for the tac_plus (tacacs+) daemon. .\" .PP Each line contains either one of the directives documented below, white-space (blanks or tabs), or a comment. .PP Syntax enclosed in angle brackets (<>) below, refer to syntax documented elsewhere in this manual page. .\" .SH "TOP-LEVEL DIRECTIVES" .\" .TP .B # Comments begin with a '#' character and extend to the end of the line. Comments may appear anywhere in the configuration file. To disable the special meaning of the '#' character, enclose the string containing it in double quotes ("#"). .TP .B accounting Only one configurable account parameter exists, the destination. All accounting records are either written to a file, .BR syslog(3) at priority info, or both. .sp .nf accounting syslog; accounting file = .fi .sp The default .B filename is @TACPLUS_ACCTFILE@. .sp Since accounting requests occur (and are serviced) asynchronously, it is necessary to lock the accounting file so that two writers do not simultaneously write to it. The daemon uses .BR fcntl(2) to lock the file. Although .BR fcntl(2) locking over NFS is supported on some implementations, it is notoriously unreliable. Even if it is reliable, locking is likely to be extremely inefficient over NFS. The file is best located on a local file system. .\" .TP .B acl If compiled with acl support (--enable-acls), Access Control Lists can be defined to limit user's (or group's) login and/or enable access by daemon client IP address or hostname. An acl is referenced by its name, but must be defined before it can be referenced. .sp The acl is a series of permit or deny statements applied to the source IP address that the client used to connected to the daemon. The first that matches ends the evaluation and the result is the permit or deny on left. If no entry of the acl matches a given address, the result is an implicit deny. .sp .nf acl = { = # deny 66.1.255/24, allow all else in 66.1/16 deny = ^66\\.1\\.255\\. permit = ^66\\.1\\. # implicit deny (ie: anything else) } .fi .sp Briefly, if a company had all their loopback interfaces numbered from 66.1/16 (and thus all the tacacs clients are within 66.1/16), this acl might be used to dis-allow a user to login to (or enable on) any router whose loopback interface is in 66.1.255/24. .sp Note: because acls match against the daemon client's source IP address, the client should be configured to use a stable source such as a loopback interface. For example: .nf ip tacacs-server source-interface loopback 0 .fi .\" .TP .B default authentication By default, authentication fails for users that do not appear in the configuration file. This overrides that behavior, thus permitting all authentication requests for such users. .sp .nf default authentication = file .fi .sp Such users will be authentication via the "DEFAULT". .sp Also see "user = DEFAULT", , and . .\" .TP .B group Analogous to a and accepting the same syntax, a group provides a template of which a or another group can be a member. .sp .nf group = { } .fi .sp A group may be recursive; that is a group may be a member of one other group (which may be a member of yet another group, and so on). .\" .TP .B host The host clause allows the configuration values noted below to be set for the client named by IP address. If .B tac_plus is started with the .B \-L option, the name can also be name as resolved from the address with the .BR gethostbyaddr(3) system call, which may be the FQDN (Fully Qualified Domain Name) if DNS is used. It is recommended that the IP address be used, since the resolver can be slow to timeout when network faults exist. .sp .nf host = { key = prompt = enable = } .fi .sp key specifics the packet encryption for this host. .sp prompt specifies the username prompt that will be presented to a user. .\" .TP .B key Specifies an encryption key used to encrypt packets between the daemon and clients. This key must match the key configured on the clients. .sp key = .sp The double quotes are only necessary if your key contains white-space, key-words, or special characters. .sp Note: encryption is highly recommended. .\" .TP .B logging Specifies the .BR syslog(3) facility used. By default, logs are posted to the daemon facility. .sp .nf logging = .fi .\" .TP .B user Define a user whose username is . .sp .nf user = { [ ] } .fi .sp Note: seventeen special usernames exist: "DEFAULT", "$enable$", and "$enabN$" (where N is a privilege level number, normally in the range 0-15 on a Cisco). The "$enable$" user is for backward compatibility with previous versions of tacacs that is queried for privilege level 15 in addition to "$enab15$". .sp Also see the "priv-lvl" AV pair in the "AV Pairs" section below and the directive. .\" .TP .B service .nf user = { [ default service = ] * * } .fi .sp Also see the directive. .\" .PP .\" .SH "ADDITIONAL DIRECTIVE SYNTAX" .\" .TP .B attr_value_pair Specify an AV (Attribute Value) pair. The "optional" keyword specifies that the AV pair is optional. .sp .nf [ optional ] = .fi .sp Optional AV pairs are only sent to the client if it requests them. That is, the client must have included the given AV pair as a mandatory or optional pair in the request. .sp Some clients react incorrectly and negatively to receiving AV pairs that it did not solicit. Optional AV pairs should be ignored if they are not recognized or not supported in any given context. .sp Also see the "Configuring Authorization" and "AV Pairs" sections below. .\" .TP .B cmd_auth Specify command authorization. .sp For command authorization, the device should expand all abbreviated commands to their full names and compress adjacent white-space. For example, when the command "config t" is entered it will be expanded to "configure terminal". .sp .nf cmd = { } .fi .sp .\" .TP .B cmd-match Specify a command argument match. .sp .nf ... .fi .sp The matches arguments of the command . For example, to allow show diag but no other show commands: .sp .nf cmd = show { permit diag deny } .fi .sp The end of the has an implicit determined by . So, if the 'deny' had been omitted in the example above, the result of the authorization would be the value of . .sp Note: 'cmd-arg' should never appear in a configuration file.

For example, to authorize a dialin ppp user for IP, the following authorization requests would be made from the client: .TP 1) An initial authorization request to startup ppp from the exec, using the AV pairs service=ppp protocol=ip, will be made (Note: this initial request will be omitted if you are autoselecting ppp, since username will not be known yet). .sp This request is really done to find the address for dumb PPP (or SLIP) clients who cannot do address negotiation. Instead, they expect you to tell them what address to use before PPP starts up, via a text message. .TP 2) Next, an authorization request is made from the PPP subsystem to see if ppp's LCP layer is authorized. LCP parameters can be set at this time (e.g. callback). This request contains the AV pairs service=ppp protocol=lcp. .TP 3) Next an authorization request to startup ppp's IPCP layer is made using the AV pairs service=ppp protocol=ipcp. Any parameters returned by the daemon are cached. .TP 4) Next, during PPP's address negotiation phase, each time the remote peer requests a specific address, if that address isn't in the cache obtained in step 3, a new authorization request is made to see if the peers requested address is allowable. This step can be repeated multiple times until both sides agree on the remote peer's address or until the NAS (or client) decide they're never going to agree and they shut down PPP instead. .PP As you can see from the above, a program which plans to handle authorization must be able to handle a variety of requests and respond appropriately. .PP Authorization must be configured on both the client and the daemon to operate correctly. By default, the client will allow everything until configured to make authorization requests to the daemon. .PP With the daemon, the opposite is true; by default, the daemon will deny authorization of anything that isn't explicitly permitted. .PP Authorization allows the daemon to deny commands and services outright, or to modify commands and services on a per-user basis. Authorization on the daemon is divided into two separate parts: commands and services. .PP Authorizing: .TP .B commands Exec commands are those commands which are typed at a Cisco exec prompt. When authorization is requested by the NAS, the entire command is sent to the daemon for authorization. .sp Command authorization is configured by specifying a list of s to match command arguments and an action which is a . .sp The following permits user Fred to run these commands: .sp .nf telnet 131.108.13. and telnet 128..12.3 and show .fi .sp All other commands are denied (by default). .sp .nf user=fred { cmd = telnet { # permit specified telnets permit 131\\.108\\.13\\.[0-9]+ permit 128\\.[0-9]+\\.12\\.3 } cmd = show { # permit show commands permit .* } } .fi .sp The command and arguments which the user types are matched to the regular expressions specified in the configuration file (in order of appearance). The first successful match performs the associated action (). If there is no match, the command is denied by default. .sp .sp Also see the , , , and directives. .\" .SH "AUTHORIZATION SCRIPTS" .\" There are some limitations to the authorization that can be done using a configuration file. One solution is to arrange for the daemon to call user-supplied programs to control authorization. These "callouts" permit almost complete control over authorization, allowing you to read all the fields in the authorization packet sent by the client, including all its AV pairs, and to set authorization status and send a new set of AV pairs to the client in response. .PP Pre and post authorization programs are invoked by handing the command line to the Bourne shell. On most Unix systems, if the shell doesn't find the specified program it returns a status of one, which denies authorization. However, at least one Unix system (BSDI) returns a status code of 2 under these circumstances, which will permit authorization, and probably isn't what you intended. .PP Note: if your program hangs, the authorization will time out and return an error on the client, and you'll tie up a process slot on the daemon host, eventually running out of resources. There is no special code to detect this in the daemon. .PP The daemon communicates with pre and post (before and after) authorization programs over a pair of pipes. Programs using the standard i/o library will use full buffering in these circumstances. This should not be a problem, since AV pairs will be read until end of file (EOF) is seen on input, and output will be flushed when they exit. .PP Fields from the authorization packet can be supplied to the programs as arguments on the command line by using the appropriate dollar-sign variables in the configuration file. These fields are: .PP .nf user -- user name name -- client/NAS name ip -- client/NAS IP port -- client/NAS port address -- user address (remote user location) priv -- privilege level number (0-15) method -- a digit (1-4) type -- digit (1-4) service -- digit (1-7) status -- (pass, fail, error, unknown) .fi .PP Unrecognized variables will appear as the string "unknown". .PP AV pairs from the authorization packet are fed to the program's standard input, one per line. The program is expected to process the AV pairs and write them to its standard output, one per line. What happens then is determined by the exit status of the program. .PP Note: when AV pairs containing spaces are listed in the configuration file, you need to enclose them in double quotes so that they are parsed correctly. AV pairs which are returned via standard output do not need delimiters and so should not be enclosed in double quotes. .PP Note: unless special arrangements are made, the daemon will run as root and hence the programs it invokes will also run as root, which is a security weakness. It is strongly recommended that FQPNs are used when specifying programs to execute, and that the daemon is compiled with unprivileged user and group IDs (--with-userid and --with-groupid) so that the daemon is not running as root when calling these programs, .PP Calling scripts .TP .B before authorization Specify a per-user program to be called before any other authorization attempt is made by using a "before" clause. .sp .nf user = auth1 { before authorization "/path/pre_authorize $user $port $address" } .fi .sp The AV pairs sent from the NAS will be supplied to the program standard input, one pair per line. .sp If the program returns a status of 0, authorization is unconditionally permitted. No further processing is done on this request and no AV pairs are returned to the client. .sp If the program returns a status of 1, authorization is unconditionally denied. No further processing is done on this request and no AV pairs are returned to the client. .sp If the program returns a status of 2, authorization is permitted. The program is expected to modify the AV pairs that it receives on its standard input (or to create entirely new ones) and to write them, one per line, to its standard output. The new AV pairs will be sent to the client with a status of AUTHOR_STATUS_PASS_REPL. No further processing takes place on this request. .sp If the program returns a status of 3, authorization is denied, but all attributes returned by the program via stdout are returned to the client. Also, whatever the program returns on stderr is placed into the server-msg field and returned to the client. .sp Any other status value returned from the program will cause an error to be returned to the client. .sp Note: a status of 2 is not acceptable when doing command authorization. .\" .TP .B after authorization Specify a per-user program to be called after authorization processing has been performed by the default, but before the authorization status and AV pairs have been transmitted to the client, by using a "after" clause. .sp .nf group = auth1 { after authorization "/path/post_authorize $user $port $status" } .fi .sp The AV pairs resulting from the authorization algorithm that the daemon proposes to return to the NAS, are supplied to the program on standard input, one AV pair per line, so they can be modified if required. .sp The program is expected to process the AV pairs and write them to its standard output, one per line. What happens then is determined by the exit status of the program: .sp If the program returns a status of 0, authorization continues as if the program had never been called. Use this if (for example) to just send mail when an authorization occurs, without otherwise affecting normal authorization. .sp If the program returns a status of 1, authorization is unconditionally denied. No AV pairs are returned to the NAS. No further authorization processing occurs on this request. .sp If the program returns a status of 2, authorization is permitted and any AV pairs returned from the program on its standard output are sent to the NAS in place of any AV pairs that the daemon may have constructed. .sp Any other value will cause an error to be returned to the NAS by the daemon. .PP Current attributes are: .sp .nf "unknown" "service" "start_time" "port" "elapsed_time" "status" "priv_level" "cmd" "protocol" "cmd-arg" "bytes_in" "bytes_out" "paks_in" "paks_out" "address" "task_id" "callback-dialstring" "nocallback-verify" "callback-line" "callback-rotary" .fi .sp Also see the "AV Pairs" section below. .\" .SH "AV PAIRS" .\" AV (Attribute Value) pairs are text strings exchanged between the client and server of the form "attribute=value".

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 LIBS libraries to pass to the linker, e.g. -l CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if you have headers in a nonstandard directory CPP C preprocessor YACC The `Yet Another Compiler Compiler' implementation to use. Defaults to the first program found out of: `bison -y', `byacc', `yacc'. YFLAGS The list of arguments that will be passed by default to $YACC. This script will default YFLAGS to the empty string to avoid a default value of `-d' given by some make applications. Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.

Quick Installation Guide (an example): 1) ./configure [--prefix=] By default, All tac_plus crud will be installed under /usr/local. This can be overridden with the --prefix option. E.g.: ./configure --prefix=/usr/pkg see ./configure --help for other configure options. 2) make install 3) it may be necessary, or you may want to, add tacacs to your /etc/services file in order for tacacs to work properly. eg: tacacs tcp/49 4) read the tac_plus(8) manual page 5) Send any bugs, suggestions or updates to tac_plus@shrubbery.net. See the web page at http://www.shrubbery.net/tac_plus.

Can the daemon authenticate against LDAP, SecurID, and similar? A). PAM is the best manner of integrating LDAP, SecurID, and similar with Tacacs. Tacacs then uses PAM to resolve authentication requests and PAM in-turn makes queries to/through the given service. Some PAM configuration is necessary. There are at least three different PAM configuration methods; no attempt to guide your configuration has been made by us. To use PAM, the daemon must have been built with PAM support. The configure script attempts to location the PAM libraries by default and will include PAM support if they're found. Otherwise, you have to figure out why its not finding them. On Linux, the pam-dev library packages are needed. Q). Does tac_plus required a working DNS? A). As distributed, whenever a START packet arrive, the daemon makes a call to getpeername to find out the name of the requestor. Depending entirely on how your Unix host is set up, this may make DNS queries. If this is a problem, comment out the code in tac_plus.c which does this, and just use ip addresses instead of host names. Q). Is the "name" field used for anything A). No. It's purely for documentation. I had once thought it might be useful when outputting error messages, and that you might need the information if you converted a passwd(5) style file, but no use is currently made of the field. Q). Why do I get PPP authorization failures because of "no username in request" when I've already logged in and authenticated? A). With "aaa authentication PPP default tacacs+", the ppp authentication overrides the earlier login authentication. If the ppp authentication fails, the username ends up blank. Changing the config to "aaa authentication ppp default if-needed tacacs+" fixes this problem. Q). I'm sure I configured it correctly, but accounting still doesn't work. A). You will find that although you can configure accounting in 10.3, and it outputs debug messages, it doesn't send any accounting packets. This is because Accounting only works from 11.0 onwards. Q). Does TACACS+ use a database instead of a flat (/etc/passwd like) file to decrease search times, say if we are talking about a large database of 40,000 users? A). The TACACS+ authentication database is held internally as a hash table. This makes lookup times fast and fairly linear, at the expense of making the server use potentially large amounts of memory space. NOTE: If you specify that the server uses passwd(5) files for authentication, then you don't get this speed benefit, but you save space. If you're willing to write the code, it should be a relatively simple matter to interface the code to a database scheme e.g. unix dbm files, or some proprietary database package, if you wish. Q). Is there any way to avoid having clear text versions of the ARAP and CHAP secrets in the configuration file? A). CHAP and ARAP require that the server knows the cleartext password (or equivalently, something from which the server can generate the cleartext password). Note that this is part of the definition of CHAP and ARAP, not just the whim of some Cisco engineer who drank too much coffee late one night. If we encrypted the CHAP and ARAP passwords in the database, then we'd need to keep a key around so that the server can decrypt them when CHAP or ARAP needs them. So this only ends up being a slight obfuscation and not much more secure than the original scheme. In extended TACACS, the CHAP and ARAP secrets were separated from the password file because the password file may be a system password file and hence world readable. But with TACACS+'s native database, there is no such requirement, so we think the best solution is to read-protect the files. Note that this is the same problem that a kerberos server has. If your security is compromised on the kerberos server, then your database is wide open. Kerberos does encrypt the database, but if you want your server to automatically restart, then you end up having to "kstash" the key in a file anyway and you're back to the same security problem. So storing the cleartext password on the security server is really an absolute requirement of the CHAP and ARAP protocols, not something imposed by TACACS+. We could have chosen a scheme where the NAS sends the challenge information to the TACACS+ daemon and the daemon uses the cleartext password to generate the response and returns that, but that means that we must include specific protocol knowledge into the protocol for both ARAP and CHAP and we would have to update the protocol every time a new authentication protocol is added. Hence we decided to go with the SENDPASS mechanism. Note that the above doesn't apply to PAP. You can keep an inbound PAP password des-encrypted, since all you need to do with it is verify that the password the principal gave you is correct. Q). How is the typical login authentication sequence done? A). NAS sends START packet to daemon Daemon send GETUSER containing login prompt to NAS NAS prompts user for username NAS sends pkt to daemon Daemon sends GETPASS containing password prompt to the NAS NAS prompts user for password NAS sends pkt to daemon Daemon sends accept, reject or error to NAS Q). Is there a GUI for the configuration file? A). No. Use your favourite text editor. Q). What does "default service = permit" really do? A). When a request comes in to authorize exec startup, or ppp (with protocol lcp, ip, ipx), or slip, or arap or a specific command, the daemon looks for a matching declarations for the user (or groups the user is a member of). For exec startup, it looks for a "service=exec" OR any command configured. For ppp, it looks for a "service=ppp" and "protocol=(one of lcp, ip, ipx)". For slip there must be a "service=slip" and for arap a "service=arap" clause. For specific commands, there must be a matching cmd=. If these aren't found, authorization will fail, *unless* you say "default service = permit". Q). How do I make PAP work? A). Avoid using PAP if possible since it's not very secure. If you *must* use it, PAP passwords may be specified along with arap and chap passwords for each user. Note that the details of this changed in version 3.0 and onwards. For outbound PAP, where you are forced to send a password to the remote host to identify yourself, there is now a separate "opap" directive e.g. opap = cleartext OOOO You use this to set the outbound PAP password. It must be a cleartext password. NOTE: It is very bad practice to use an outbound PAP password that is the same as any of your inbound passwords. For this reason, a "global" password does not apply to outbound PAP, only to inbound PAP, bidirectional CHAP and ARAP. Before 3.0, PAP logins were treated like ordinary user logins, so you needed to declare a user in the Daemon configuration file whose name was typically the remote hostname (or user), with a login password, in order to process the PAP request. Q). How can I deny some one from telneting from a commserver by ip address only. i.e. when command is 10.0.1.6 rather than telnet 10.0.1.6. A). The best way to restrict telnet access is by applying an outbound access list via the access class command (or equivalently, via the "acl" avpair). The NAS configuration command "access-class out" for example applies a pre-defined standard IP access list (where n is a number from 1 through 99) that governs telnet access from a NAS. E.g. the following configuration commands permit outgoing Telnet access from line 1 on the NAS *only* to hosts on network 192.85.55.0: access-list 12 permit 192.85.55.0 0.0.0.255 line 1 access-class 12 out Note: you must define "access-list 12 permit 192.85.55.0 0.0.0.255" on the NAS. Only then can you use the acl avpair to apply it to a line that a user dials in on. Alternatively, you can try configuring "transport preferred none" on the lines in question. This will force a user to always type "telnet 10.0.1.6" in order to telnet out from the NAS. Then you can apply command authorization to this command to restrict it. Q). I have an autocommand configured in the NAS-local database and I'm using "aaa authentication local-override". The autocommand doesn't work, but the username/password does. Why? A). The "local-override" only applies to the authentication portion of the local database, so if you want an autocommand for this user, you need to also do: aaa authorization exec local if-authenticated This will use the local DB entry if one exists, allow authenticated users otherwise, or fail. We don't have a "aaa authorization local-override" like we do for authentication. Unlike authentication, the local method for authorization is sort of equivalent to a local-override. Q). Can tacacs+ only be enabled on a global basis? I want to selectively turn it on for, e.g. only modem-connected lines. How do I do this? A). You turn tacacs+ ON on a global basis, but you can then change the behavior of individual lines to whatever you want, e.g. aaa authentication login default tacacs+ none aaa authentication login oldstyle line aaa authentication login none none line 1 16 login authentication default line vty 0 4 login authentication oldstyle line 0 login authentication none Note that unfortunately, you can't (yet) apply authorization differently to selected lines and interfaces. Q). I have leased lines running PPP, and AAA authorization is also configured, so the authorization on the leased lines fails. What should I do? A). Since you can't (yet) configure authorization on a per-line basis, you have to turn on authentication on the leased lines running PPP and configure your T+ server so that it will authorize these lines correctly. A more demanding alternative is to modify the TACACS+ server source code to allow any authorizations coming in from the port "SerialXXX" to succeed. A third possibility is to not use PPP on those lines, e.g. use HDLC instead. HDLC doesn't require authentication or authorization. Q). What are the memory recommendations for TACACS+? A). Unless you're using passwd style files, TACACS+ holds entries in hash tables in memory. The overhead is modest e.g. each user entry occupies 72 bytes, plus space for strings like username and password etc. Access time should thus be pretty constant regardless of number of users. On a sparc 2, a config file containing 2000 users requires about 0.5M of swap. Q). How many users will a TACACS+ server support? What happens when the maximum is exceeded? There are 2 issues. The first is that each entry in the config file occupies memory (swap space) so you could run out of swap space either starting up the daemon or when it forks to answer incoming requests (see above). If this happens, the daemon will drop the connection which should appear as an error to the NAS) and the logfile will contain appropriate error messages. The solution is usually to add more disk space for swapping. The second issue is speed: Using config files containing 75,000 user entries, I'm seeing about 3 authentications per second on a sparc 2 without noticeable performance impact, though I haven't benchmarked this formally. So more than about 3 authentications per second on this platform will result in users seeing delays and having to wait for prompts. The usual solution to this is to add more daemons to spread the load out. Q). How many characters may a TACACS+ Username and Password contain? A). The short answer is 31 bytes of username, with up to 254 bytes of password if they are cleartext (8 bytes if passwords are des encrypted). The long answer is that the Cisco NAS allocates a buffer of 1024 bytes, so this is the maximum you can type in, in response to a NAS prompt. But the protocol spec allows a username or password length field of just one byte in an authentication packet, so only the first 255 of these characters can be sent to the daemon. Then, the API spec states that the username in the identity structure on the daemon is 32 bytes long, so only the first 31 bytes of username will be copied from the authentication packet into this structure, which is then null-terminated. The password, on the other hand, is copied into malloc'ed memory, so it can still be up to 255 characters long. Now if it's a des encrypted password, then only the first 8 bytes are significant, per the common unix implementations of crypt. Lastly, there is also the question of how long a username/password can be configured in the daemon configuration file. The answer is given by the value of MAX_INPUT_LINE_LEN, currently set to 255, which determines the length of the longest string you can enter in the configuration file. Q). What is the format of accounting records? A). Accounting records are text lines containing tab-separated fields. The first 6 fields are always the same. These are: timestamp, NAS name, username, port, address, record type. Following these, a variable number of fields are written, depending on the accounting record type. All are of the form attribute=value. There will always be a task_id field. Current attributes are: "unknown" "service" "start_time" "port" "elapsed_time" "status" "priv_level" "cmd" "protocol" "cmd-arg" "bytes_in" "bytes_out" "paks_in" "paks_out" "address" "task_id" "callback-dialstring" "nocallback-verify" "callback-line" "callback-rotary" I expect more will be added over time. Example records are thus: Thu Jul 13 13:35:28 1995 cherub.cisco.com chein tty5 171.69.1.141 stop task_id=12028 service=exec port=5 elapsed_time=875 Thu Jul 13 13:37:04 1995 cherub.cisco.com lol tty18 171.69.1.129 stop task_id=11613 service=exec port=18 service=exec port=18 elapsed_time=909 Thu Jul 13 14:09:02 1995 cherub.cisco.com billw tty18 171.69.1.152 start task_id=17150 service=exec port=18 Thu Jul 13 14:09:02 1995 cherub.cisco.com billw tty18 171.69.1.152 start task_id=17150 service=exec port=18 service=exec port=18 Elapsed time is in seconds, and is the field most people are usually interested in. Q). How do I limit the number of sessions a user can have? A). The TACACS+ daemon can enforce how many simultaneous sessions a given user is allowed to have. You must compile the daemon with the MAXSESS symbol defined (see the Makefile). Maximum sessions are configured on the daemon for a user as follows: user = joeslip { login = cleartext XXX # only allow two sessions max for joeslip maxsess = 2 name = "Joe SLIP User" ... } It can also be configured under a group: group = slip_users { maxsess = 2 ... } ... user = fred { ... member = slip_users ... } The daemon keeps a count of how many sessions a given user owns by monitoring START and STOP accounting records. Thus, exec and network accounting must be configured for this feature to operate for exec and ppp users. As the restriction is enforced during the authorization phase of login, exec and network authorization must be configured as well, viz: aaa authentication login default tacacs+ aaa authentication ppp default tacacs+ aaa authorization exec tacacs+ aaa authorization network tacacs+ aaa accounting exec start-stop tacacs+ aaa accounting network start-stop tacacs+ Due to network outages (or other disruptions), it is possible for the TACACS+ daemon's record of usage to become out of sync with reality, so before denying access because it thinks a user is running too many sessions, the TACACS+ daemon will use the finger service on the NAS to verify how many sessions a user is running there. If the result of finger indicates that the daemon should permit access, access will be granted. Note that for this check to work via finger, "service finger" must also be configured on the NAS. Lastly, note that because finger output truncates usernames at 10 characters, you may encounter trouble if you have users whose names are not unique within those first 10 characters. Also recall that authorization works differently on the console. So many people locked themselves out of their boxes after configuring authorization, that we stopped requiring authorization on the console for authenticated users. Since there's no authorization on the console, MAXSESS is not enforced there. Q). How can I configure time-outs on an interface via Tacacs+? A). Certain per-user/per-interface timeouts may be set by Tacacs+ during authorization. As of 11.0, you can set an arap session timeout, and an exec timeout. As of 11.1 you can also set an exec idle timeout. There are currently no settable timeouts for PPP or SLIP sessions, but there is a workaround which applies to ASYNC PPP/SLIP idle timeouts started via exec sessions only: This workaround is to set an EXEC (idletime) timeout on an exec session which is later used to start up PPP or SLIP (either via a T+ autocommand or via the user explicitly invoking PPP or SLIP). In this case, the exec idle timeout will correctly terminate an idle PPP or SLIP session. Note that this workaround cannot be used for sessions which autoselect PPP or SLIP. An idle timeout terminates a connection when the interface is idle for a given period of time (this is equivalent to the "session-timeout" Cisco IOS configuration directive). The other timeouts are absolute. Of course, any timeouts set by Tacacs+ apply only to the current connection. user = lol { login = cleartext foobar service = exec { # disconnect lol if there is no traffic for 5 minutes idletime = 5 # disconnect lol unconditionally after one hour timeout = 60 } } You also need to configure exec authorization on the NAS for the above timeouts, e.g. aaa authorization exec tacacs+ Note that these timeouts only work for async lines, not for ISDN currently. Note also that you cannot use the authorization "if-authenticated" option with these parameters, since that skips authorization if the user has successfully authenticated. Q). How do I send VPDN forwarding decisions to an authorization server? A). In 11.2 onwards, VPDN NASs can use T+ to allow an authorization server to make the decision to forward users. If VPDN forwarding is turned on, and the username is of the form user@domain, and "domain" matches a vpdn outgoing configured domain, then an authorization attempt is made for "domain" (see below). When making an authorization call for VPDN, a service type of "ppp" with a protocol type of "vpdn", with a username of "domain" will be made e.g. when a PPP user comes up on a line with the username foo@bar.com, if "vpdn enable" and "aaa authorization ...." is enabled on the box, then a one-time authorization of the name "bar.com" is attempted. If this authorization is successful, no local authentication is attempted on the NAS, and the connection is forwarded via VPDN instead. If no VPDN-specific information comes back from this authorization call, the login proceeds as follows: If tacacs-server directed-requests are configured (note: this is true by default), then IOS will strip off the domain part of a name of the form user@domain and use "domain" to try and select a T+ server. If successful, the username portion "user", without the domain, will be used for all subsequent authentication, authorization and accounting. If directed requests are turned off, then the entire username user@domain is treated as a username. vpdn specific information includes the attributes "tunnel-id", "source-ip" (deprecated) and "ip-addresses": tunnel-id: This AV pair specifies the username that will be used to authenticate the tunnel over which the individual user MID will be projected. This is analogous to the "NAS name" in the "vpdn outgoing" command. ip-addresses: This is a list of possible IP addresses that can be used for the end-point of the tunnel. Consult the text at the end of this document for more details on how to configure this attribute. source-ip: (This is now deprecated. It began in release 11.2(1.4), and was removed in 11.2(4.0.2)). This ip address will be used as the source of all VPDN packets generated as part of the VPDN tunnel (see the source-ip keyword in the vpdn outgoing command). Tacacs+ syntax -------------- The following syntax is used on the public domain Tacacs+ server. username = domain { service = ppp protocol = vpdn { tunnel-id = ip-addresses = [ ...] source-ip = } } In addition the T+ server can be used to store the usernames for both the NAS (the username specified by "tunnel-id" above) and the Home Gateway. These will be used to authenticate the tunnel. Example: user = foobar.cisco.com { service = ppp protocol = vpdn { tunnel-id = my_nas ip-addresses = "173.20.12.19 173.20.12.20" source-ip = 173.5.10.1 } } user = my_nas { global = cleartext egad } user = my_home_gateway { global = cleartext wowser } IOS Configuration ----------------- To enable AAA assisted VPDN forwarding on a NAS, the following minimum configuration is required: vpdn enable aaa new-model aaa authorization network tacacs+ ... In addition, if the passwords for the home gateway and NAS are stored on the T+ daemon, the command aaa authentication login tacacs+ .... should also be present. Beginning with release 11.2(1.4), the additional configuration vpdn outgoing cisco.com ip NAS [ source-ip X.X.X.X ] can be used. This changes in 11.2(4.0.2) and becomes: vpdn source-ip X.X.X.X vpdn outgoing cisco.com ip NAS Q). Can someone expand on the use of the "optional" keyword. A). Most attributes are mandatory i.e. if the daemon sends them to the NAS, the NAS must obey them or deny the authorization. This is the default. It is possible to mark attributes as optional, in which case a NAS which cannot support the attribute is free to simply ignore it without causing the authorization to fail. This was intended to be useful in cutover situations where you have multiple NASes running different versions of IOS, some of which support more attributes than others. If you make the new attributes optional, older NASes could ignore the optional attributes while new NASes could apply them. Note that this weakens your security a little, since you are no longer guaranteed that attributes are always applied on successful authorization, so it should be used judiciously. Q). Can I do do address pooling on the T+ daemon? A). Not really since nothing on the daemon tracks whether an address is already in use. The best way to do manage address pools is to define a non-overlapping pool of addresses on each NAS and return the name of this pool during authorization whenever a user logs in e.g. NAS: ip local pool foo 1.0.0.1 1.0.0.10 Daemon: user = lol { service = ppp protocol = ip { addr-pool = foo } } Q). What about MSCHAP? A). Version F4.X contains mschap support. Mschap is configured the same way as chap, only using the "mschap" keyword in place of the "chap" keyword. Like ARAP, MSCHAP works best when you have a des library (see the note at the beginning of this document), but this is optional, as the DES calculation can be done by the NAS instead. It also optionally requires a key from Microsoft which is not public domain, but this can also be done on the NAS too, so you can live without it. To compile the daemon with MSCHAP support, give configured the --enable-mschap option. This will add the MSCHAP code to your daemon. You can leave MSCHAP_DES undefined (see configure --enable-mschapdes), in which case the MSCHAP DES calculation will be done by NAS, and no special MSCHAP key will be required. If want to use DES with MSCHAP (this is more efficient for authentication), then you also give configure the --enable-mschapdes option. This will ensure that the DES calculation is done in the daemon. A key will need to be obtained from Microsoft and used to replace the definition of MSCHAP_KEY in the file mschap.h. If you're thinking by now that this is all too much trouble, you're right. Q). Can I do wtmp-style logging like xtacacd used to do? A). Wtmp file logging is supported. The "-u " command line flag can be used to specify a filename which will be used for logging wtmp style records instead of the regular T+ accounting records. wtmp records are generated into wtmpfilename. Since file locking is also used when writing to wtmpfilename, the usual provisos regarding NFS and locking (see accounting above) should be observed. To generate correct wtmp log records, the NAS needs to be configured as follows: aaa accounting exec stop-only tacacs+ aaa accounting network stop-only tacacs+ aaa accounting system start-stop tacacs+ Q) How does TACACS compare to RADIUS?

When authorizing enable requests, the daemon used to prompt for a username which it then ignored. It no longer prompts for a username. Fix recursion issues with service and command lookups. They are now fully recursive c.f. password lookups. Add debugging output to password verification to provide information about expiry processing. Keep track of longest hash chain we create, for fine tuning. Hash all keywords into a keyword table instead of doing linear lookup. Update users_guide to reflect the new configuration syntax. The convert.pl script now generates the new configuration file syntax. Accounting code now honours the "more" flag. Changes from Release 0.1 to release 0.2 --------------------------------------- You can now send a SIGHUP to the daemon to cause it to reinitialize itself and re-read its CONFIG file. There is a new debugging flag devoted to this section of the code. Node types are now pretty-printed in debug output. The conversion script "convert.pl" now will not print out an expires field if it doesn't think the syntax of the field is correct. It also now ignores blank lines in its input files. When doing authorization, the NAS supplied attribute "cmd=" is now correctly ignored. This would previously have caused exec authorization to be denied. Changes from Release 0.2 to release 0.3 --------------------------------------- Warn when not invoked as uid 0. Improved Usage message Add make install target Changes from Release 0.3 to release 0.4 --------------------------------------- Add TAC_PLUS_PIDFILE to makefile per Andy Linton's suggestion. Fix bug in authorization code (protocol field needs to be uppercase) which prevented authorization from working. Changes from Release 0.4 to release 0.5 --------------------------------------- Add pre and post authorization calls to shell commands. Minor bugfixes and code cleanup The "More" bit in accounting records is now honoured. Fix a bug in convert.pl Redo accounting output routines. You can now name the accounting file in the configuration file. Change "svc" to "service" and "proto" to "protocol". You can use any string to name a ppp protocol, even one which doesn't yet exist. Add PPP/LCP special case processing Revised authorization algorithm (see user's guide) Add hex debug flag to allow skipping hex in packet dumps. Update user's guide to reflect changes Changes from Release 0.4 to release 1.0 --------------------------------------- Changed format of syslog messages to make writing scripts easier Added ability to use cleartext passwords instead of DES passwords Updated man page to reflect the fact that we use SIGUSR1 to re-read the config file. SIGHUP is now ignored. Updated the users guide. Changes from Release 1.0 to release 1.1 --------------------------------------- Release 1.1 corresponds to RCS version 1.64 of tac_plus (see tac_plus -v) A typo in the Solaris section of the Makefile has been fixed. The keyword 'des' has been introduced which must be used before all des encrypted passwords. The keyword 'password' has been changed to 'login', so password = f23sac783n has become login = des f23sac783n The convert.pl script knows about these changes. arap and chap now require the keyword 'cleartext' in front of their passwords. A cleartext, per-user, global password can now be configured, which works for login, arap and chap. The users_guide has been updated to include a list of all A/V pairs recognised by IOS 10.3(3) code. Some solaris binaries have been provided as a courtesy. Changes from Release 1.1 to release 2.0 --------------------------------------- generate_password.pl has been removed in favour of a C program generate_passwd.c The version number reported by tac_plus has been changed to agree with the release number. This is why the version has jumped to 2.0 skey was broken by changes made in 1.1. These are now fixed. Documentation has been added for the authorization AV pairs supported by IOS releases 10.3(3) and 11.0. Changes from Release 2.0 to release 2.1 --------------------------------------- There are now Makefile definitions for most of the major platforms. Minor changes to remove some spurious debugging output. A prematurely closed NAS connection will now call the authentication function with the abort flag set, so that it can do any clean up it requires. syslog messages will contain the string "unknown" for usernames and ports which are NULL, so that the messages always contain a fixed number of fields. The authentication code has been rearranged to better reflect the structure of the API. The "default user = permit" directive is still accepted but is now deprecated in favour of "default authorization = permit". A bug in the handling of substring AV pairs which caused the attribute "addr" to erroneously match "addr-pool" has been fixed. Added new files: enable.c generate_passwd.c skey_fn.c New #defines have been added to make it easier to port tacacs+ to new systems. Many more iterations are allowed before an error is declared. Changes from Release 2.1 to release 2.2 --------------------------------------- The expiry field in the shadow file on Solaris machines is now honored, if it exists. Added TAC_PLUS_AUTHEN_SVC_NASI Changes from Release 2.2 to release F3.0.13 ------------------------------------------- NEW REVISION OF THE PROTOCOL corresponding to tacacs+.spec.v1.63.ps (which see) to increase security in the case of compromised keys. Inbound pap logins and outbound pap password are now configurable as separate entries for each principal. Inbound pap logins are now declared by using a "pap = " configuration directive. Outbound PAP is now configured using "opap =". Substantial code rearrangement of authentication routines. Cleartext passwords can be up to 255 characters in length (previously only the first 8 characters were used). default service = permit is now fully recursive and now allows you to say default service = deny in case you belong to a group where the default is to permit. Include backward compatibility with old revision of the protocol (prior to v1.63). post_authorization scripts are now invoked for command authorization. Better sanity checking of authorization and accounting packets. The API has changed slightly. All character string fields in the identity structure are now allocated from the heap and can be up to 255 bytes long (instead of being character arrays of 32 and 64 bytes, as specified in the API document revision 1.30 or earlier). Double quotes can now appear inside strings if they are escaped with a backslash. Added code which limits the number of simultaneous sessions a user can have (see MAXSESS in the user's guide). The accounting "more" bit is gone (It was deprecated from the spec). Hooks are now in so that if you have DES code, you can do ARAP more securely, per the new protocol. The packet read/write routines now handle exceptions more gracefully. Lots of stuff added to the user's guide. If you use a port number other than the default, the pidfile has the port number appended to it, in case you are running multiple daemons. We also now remove the pidfile when the daemon terminates via SIGTERM. user = DEFAULT has been added, deprecating "default authorization = permit". See the user's guide. Arbitrary service types can now be configured in the config file. REARMSIGNAL has been added for those systems which install one-shot signal handlers which need to be rearmed after use (LINUX, HPUX). A \n can now be embedded within strings. Concede defeat. Allow SIGHUP as synonym for SIGUSR1. Avoid symbol buffer overflow by checking the maximum length of a string or token. Make peer DNS lookup on incoming connections optional. Do not close socket when servicing a SIGHUP Fix a bad bug where service/cmd declarations which were not contiguous were parsed but ignored (reported by Gabor Kiss). Patch maxsessions to not count the current port on a different NAS. Add various other fixes to maxsession code. Add timeout to finger read routine.

It allows a user to be part of many predefined groups that can allow different access to different devices based on ip, user, and source address. Do not play with do_auth untill you have a firm grasp on tac_plus! -u Username. Mandatory. $user -i Ip address of user. Optional. If not specified, all host_ entries are ignored and can be omitted. $address **Note: If you use IOS-XR, you MUST add -fix_crs_bug after $address due to a bug in IOS-XR -d Device address. Optional. If not specified, all device_ entries are ignored and can be omitted. $name -f Config Filename. Default is do_auth.ini. -l Logfile. Default is log.txt. -D Debug mode. Allows you to call the program without reading from stdin. Useful to test your configuration before going live. Sets a default command of "show users wides". Groups are assigned to users in the [users] section. A user must be assigned to one or more groups, one per line. Groups are defined in brackets, but can be any name. Each group can have up to 6 options as defined below. host_deny Deny any user coming from this host. Optional. host_allow Allow users from this range. Mandatory if -i is specified. device_deny Deny any device with this IP. Optional. device_permit Allow this range. Mandatory if -d is specified command_deny Deny these commands. Optional. command_permit Allow these commands. Mandatory. av_pairs list of av pairs to replace if found. Optional - be careful The options are parsed in order till a match is found. Obviously, for login, the commands section is not parsed. If a match is not found, or a deny is found, we move on to the next group. At the end, we have an implicit deny if no groups match. An simple example is as follows. [users] homer = simpson_group television_group stimpy = television_group [simpson_group] host_deny = 1.1.1.1 1.1.1.2 host_allow = 1.1.1.* device_permit = 10.1.1.* command_permit = .* [television_group] host_allow = .* device_permit = .* command_permit = show.* Example tacacs line: after authorization "/usr/bin/python /root/do_auth.pyc -i $address -fix_crs_bug -u $user -d $name -l /root/log.txt -f /root/do_auth.ini" (that's one line) Example av_pair: The following example will replace any priv-lvl with priv-lvl=1 ONLY if passed. Think of "av_pairs" as a find/replace function. av_pairs = priv-lvl=1 Brocade has a brocade-privlvl which I like. It maps priv-lvl to brocade-privlvl, but priv-lvl=1 results in interface privileges. Here is an example of how to map to brocade-privlvl=5 which has no modification rights. Unfortunately, it does require you to put in the IP's of your gear. The following group would go before other groups: [brocade_readonly] host_allow = .* device_permit = 192.168.1.* command_permit = .* av_pairs = priv-lvl,brocade-privlvl=5 You could also put "priv-lvl=15,brocade-privlvl=5" or whatever your tac_plus deamon is passing; as long as it's a match it accomplished the same thing. In this example, we essentially replace the whole av_pair resulting in the user having only read access. Alternatively, a good "disable account" can be created by simpley doing: av_pairs = brocade-privlvl=5 This results in the brocades having read/only, and the Cisco's go into disable because they don't understand it. (We're assuming that the user has no enable account or the priv-lvl is pointless) You could also add a shell role for nexus, which we will discuss next. (shell:roles="network-admin") NEXUS - Due to a slight change in the nexus, do_auth is able to discern if a device is a nexus or not. In tac_plus, do the following: service = exec { priv-lvl = 1 shell:roles=\"\\"network-operator\\"" idletime = 3 timeout = 15 } after authorization This configuration does NOT work without do_auth. However, WITH do_auth, do_auth will only send shell:roles to Nexus switches, allowing your other gear to work correctly. Simply put av_pairs in your do_auth, and it will figure it out for you. (If not, it won't touch them. The logic is simple: If (av_pairs in .ini): Then (do_stuff), Else (exit(2)- Don't modify 'em!)) Roles can also be modified in a do_auth group, as below: av_pairs = priv-lvl=15 shell:roles="network-admin" Also of note, you MUST USE DOUBLE QUOTES to get tac_plus to correctly pass "network-operator" in the service example above. UNLESS you are modifying the key with do_auth in av_pairs - it will fix the quotes. BUGS: You must know your regular expressions. If you enter a bad expression, such as *. instead of .*, python re will freak out and not evaluate the expression. (Thought about netaddr, but would you really install it?) CAVEATS: One group can not take away what another group grants via deny. If a match is not found, it will go on to the next group. If a deny is matched, it will go on to the next group. Order is crucial - the groups should go from more specific to less specific. In the above example, if television_group was put before simpson_group, simpson_group would never be called because televsion_group catches everything in device_permit.

The first is a mailing list run by spot.Colorado.EDU which discusses many things pertaining to Cisco products. It is not run by Cisco Systems, Inc. and is not part of Cisco's formal service request channels, however, many knowledgeable people, including staff members of Cisco Systems, Inc. voluntarily read and respond on the list. Requests to be added to or deleted from the list at spot.Colorado.EDU, along with other administrative issues concerning it can be sent to: cisco-request@spot.Colorado.EDU There is also a relatively new list called TACPLUS-L, run by disaster.com, created for the purpose of information exchange between TACACS+ Users. It is intended as a supplement to the list at spot.Colorado.EDU, aiding TACACS+ users and prospective users in many issues including but not limited to technical support, bug reports and workarounds, configuration information, recommendations for future versions of TACACS+, and general talk about TACACS+ development, implementation, administration, etc. Please note that neither of these lists is in fact connected with Cisco Systems, Inc. or any of its subsidiaries. Standard etiquette rules apply.

Also, Robert Kiessling maintains a TACACS+ FAQ at http://www.easynet.de/tacacs-faq. Lastly, I am always interested in seeing contributed patches, so consider mailing any modifications you make, as context diffs (be sure to indicate with the version your patches are based on), to tacacs-patches@cisco.com. As always, no support is implied, nor any assurance that patches will be made available via ftp (though that is my intent) or incorporated into any code. Definitions and Terms --------------------- NAS --- A Network Access Server e.g. a Cisco box, or any other *client* which makes tacacs+ authentication and authorization requests, or generates Tacacs+ accounting packets. Daemon -- A program which services network requests for authentication and authorization, verifies identities, grants or denies authorizations, and logs accounting records. passwd(5) files -- files conforming to Unix password style format, as documented in section 5 of the Unix manuals. AV pairs -- strings of text in the form "attribute=value" sent between a NAS and a tacacs+ daemon as part of the Tacacs+ protocol. Since a NAS is sometimes referred to as a server, and a daemon is also often referred to as a server, the term "server" has been avoided here in favor of the less ambiguous terms "NAS" and "Daemon". TACACS, XTACACS and TACACS+ --------------------------- Note that there are now at least 3 versions of authentication protocol that people commonly refer to as "TACACS". The first is ordinary tacacs, which was the first one offered on Cisco boxes and has been in use for many years. The second is an extension to the first, commonly called Extended Tacacs or XTACACS, introduced in 1990. The third one is TACACS+ (or T+ or tac_plus) which is what is documented here. TACACS+ is NOT COMPATIBLE with any previous versions of tacacs. In addition to the 3 versions of tacacs running on Cisco boxes, the fact that we distribute the source code to the daemon has meant that additional implementations of tacacs daemons have been produced by people who have made modifications to our source code. BUILDING TAC_PLUS ----------------- Tac_plus is known to build and run on the following platforms: AIXv3.2 (using -DAIX and bsdcc. See tac_plus.h for more details). HP/UX A.09.01 using -DHPUX i86 Solaris 2.4 (SUNOS 5.4), using SUNpro SW2.0.1 & -DSOLARIS Sun4 Solaris 2.4 using SUNpro SC3.0.1 and -DSOLARIS SUNOS 4.1.2 sparc-2 SUNOS 4.1.3 MIPS R3K SGI IRIX 4.05F (using -DMIPS) BSDI BSD/386 1.1 (using -DBSDI) FREEBSD 2.0-RELEASE (using -DFREEBSD) LINUX 1.2.8 (using -DLINUX) To build tac_plus, untar the tarfile distribution into a clean directory e.g. tar -xvf tac_plus.tar Edit the top of the Makefile to select the appropriate defaults for your system. Then type make tac_plus The default version can authenticate using its internal database, s/key or passwd(5) style files. Authorization is done via the internal database or via calls to external programs, which the administrator configures. To use S/KEY, you must obtain and build the s/key library (libskey.a) yourself. You can then compile in S/KEY support per the instructions for S/KEY in the Makefile. I got my S/KEY code originally from crimelab.com but now it appears the only source is ftp.bellcore.com. I suggest you try a web search for s/key source code. Note: S/KEY is a trademark of Bell Communications Research (Bellcore). Should you need them, there are routines for accessing password files (getpwnam,setpwent,endpwent,setpwfile) in pw.c. Lastly, you may also need to add lines to your /etc/services file to get tacacs+ to work correctly e.g. something along the lines of: tacacs tcp/49 You'll need to consult your system manuals for exact details of how to do this. A NOTE ABOUT ARAP, MSCHAP AND DES --------------------------------- You link tac_plus with the supplied DES library for ARAP and MSCHAP with configure's --enable-arapdes and --enable-mschapdes options. This is recommended, as it will allow you to process ARAP and MSCHAP requests on your daemon, which is more efficient, and also more secure than processing them on the NAS. Lastly, this limitation of MSCHAP, ARAP and DES has no bearing on the use of des passwords for regular logins. Regular logins also use DES but they do it via the "crypt" system call, which is usually found in a library on the Unix host where you compile your daemon. There are additional restrictions on doing MSCHAP (see the FAQ later in this document). CONFIGURING TAC_PLUS --------------------- Tac_plus is configured via a single configuration file. You can create a configuration file from scratch or, if you have passwd(5) and supplementary files from earlier versions of tacacs, you can convert these to configuration file format by running the supplied perl script tac_convert. CONVERTING EXISTING PASSWD(5) FILES ----------------------------------- To convert an existing passwd(5) file e.g. one used with an older version of tacacs, use the tac_convert perl script as follows: tac_convert [-g] [] 1). If you have no supplementary file, simply omit it. 2). If the groupid field of your passwd file does NOT represent a valid acl number (e.g if it's really a unix passwd file this field is a group id, not an acl number), just omit the -g flag. The rest of this document assumes that you are configuring tac_plus from scratch. CONFIGURING TAC_PLUS FROM SCRATCH --------------------------------- A configuration file consists of some top-level directives for setting defaults and for setting up the encryption key, followed by a declaration for each user and group you want to configure. Within each user or group declaration, there are declarations for authenticating and authorizing that user. 1). Configuring the encryption key If you want tac_plus to encrypt its packets (and you almost certainly *DO* want this, as there can be usernames and passwords contained in these packets), then you must specify an encryption key in the configuration file. The identical key must also be configured on any NAS which communicates with tac_plus. This is done using the statement key = "your key here" NOTE: You only need double quotes on the daemon if your key contains spaces. Confusingly, even if your key does contain spaces, you should NEVER use double quotes when you configure the matching key on the NAS. During debugging, it may be convenient to temporarily switch off encryption by not specifying any key. Be careful to remember to switch encryption back on again after you've finished debugging. The current code does not support host-specific keys (left as an exercise to the reader). On the NAS, you also need to configure the *same* key. Do this by issuing: aaa new-model tacacs-server key COMMENTS IN CONFIGURATION FILES ------------------------------- Comments can appear anywhere in the configuration file, starting with the # character and extending to the end of the current line. Should you need to disable this special meaning of the # character, e.g. if you have a password containing a # character, simply enclose the string containing it within double quotes. CONFIGURING USERS AND GROUPS ---------------------------- Each user may belong to a group (but only one group). Each group may in turn belong to one other group and so on ad infinitum. Users and groups are declared as follows. Here we declare two users "fred" and "lily", and two groups, "admin" and "staff". Fred is a member of group "admin", and group "admin" is in turn a member of group "staff". Lily is not a member of any group. user = lily { # user lily is not a member of any group # and has nothing else configured as yet } user = fred { # fred is a member of group admin member = admin } group = admin { # group admin is a member of group staff member = staff } group = staff { # group staff is not a member of any group } RECURSION AND GROUPS -------------------- In general, when the daemon looks up values e.g. passwords, it will look first to see if the user has her own password. If not, it looks to see if she belongs to a group and if so, whether the group has a password defined. If not, this process continues through the hierarchy of groups (a group can be a member of another group) until a value is found, or there are no more groups. This recursive process occurs for lookups of expiration dates, for pap, arap and chap "secrets", and also for authorization parameters (see later). A typical configuration technique is thus to place users into groups and specify as many groupwide characteristics in the group declaration as possible. Then, individual user declarations can be used to override the group settings for selected users as needed. CONFIGURING USER AUTHENTICATION ------------------------------- User Authentication can be specified separately for PAP, ARAP, CHAP, and normal logins. In addition, a user global authentication method can be given that will be used if a per-protocol method is not specified. PAP, ARAP, CHAP, and global user authentication must be given in clear text. The following assigns the user mary five different passwords for ARAP, inbound and outbound CHAP, inbound PAP, outbound PAP, and normal login respectively: user = mary { arap = cleartext "arap password" chap = cleartext "chap password" pap = cleartext "inbound pap password" opap = cleartext "outbound pap password" login = des XQj4892fjk } The following assigns the user agnes a single password for all the above types of login (except outbound PAP): user = agnes { global = cleartext "Agnes global password" } NOTE: you cannot use a global user password for outbound PAP. This is because outbound PAP is implemented by sending the password from the daemon to the NAS. This is a security issue if the TACACS+ key is ever compromised. There are 4 ways to authenticate a user for login. 1). You can include a DES (or cleartext) password for a user or for a group that s/he is a member of, viz: user = joe { member = admin # this is lily's encrypted DES password. It overrides the admin # group's password login = des XQkR21zMB0TDU } user = fred { # fred is a member of group admin. He inherits the group's password # as he does not have his one of his own. member = admin } group = admin { # group admin has a cleartext password which all members share # unless they have their own password defined login = cleartext foobar } If no password is needed for this user, this can be accomplished with the 'nopassword' option: user = foo { login = nopassword } NOTE: The C program built from generate_passwd.c may be used to hand-generate encrypted passwords, or they may be taken from a Unix passwd (or shadow) file. 2). Authentication using passwd(5) files. For selected users, you can perform DES authentication using existing passwd(5) files instead of entering the password into the configuration file directly (though using passwd(5) files is noticeably less efficient for large files). You can specify this behavior per-user, by naming a passwd(5) file in the password declaration (instead of giving a DES password), as follows: user = fred { # look in file /etc/tac_plus_passwords to authenticate this user login = file /etc/tac_plus_passwords } 3). Authentication using s/key. If you have successfully built and linked in a suitable s/key library and compiled tac_plus to use s/key, you can then specify that a user be authenticated via s/key, as follows: user = fred { login = skey } 4). Authentication using PAM (Pluggable Authentication Modules) Assuming that your OS supports it, tac_plus can be configured to use PAM for authentication, which may make it possible to use LDAP, SecureID, etc if you have the appropriate PAM module. Use may require configuration of the PAM libraries themselves; see their documentation. user = fred { login = PAM } Be aware that when the tac_plus daemon runs as a non-root user (as is the default in FreeBSD /usr/ports), it will not be able to authenticate using the pam_unix.so module. This is because the system function getpwnam() called by pam_unix.so requires root privileges to retrieve the password to validate from the /etc/master.passwd or /etc/shadow file. The symptom will be that for each authentiction that is attempted, the password will appear to be wrong whether it was typed correctly or not. RECURSIVE PASSWORD LOOKUPS --------------------------- As stated earlier, authentication passwords are looked up recursively: The daemon looks first to see if the user has her own password. If not, it looks to see if she belongs to a group which has a password. This process recurses through the hierarchy of groups (a group can be a member of another group) until a password is found, or there are no more groups. CONFIGURING DEFAULT AUTHENTICATION ----------------------------------- By default, an unrecognized user will be denied authentication (NOTE: there is no way to authenticate someone with no username). At the top level of the configuration file, you can set the default authentication to use a passwd(5) file, viz: default authentication = file /etc/passwd The effect of this statement is that if a user does not appear in the configuration file, the daemon will attempt to authenticate the user using passwords from this file i.e. /etc/passwd in this example. If you have passwd(5) files from previous versions of tacacs daemons, this facility allows you to authenticate using the passwd(5) from older versions of tacacs, while you migrate to using the new configuration file. CONFIGURING EXPIRY DATES ------------------------ An entry of the form: user = lol { expires = "MMM DD YYYY" password = cleartext "bite me" } will cause the user's passwords to become invalid, starting on the expiry date. The only valid date format is e.g. "Jan 1 1980". Case is NOT significant. A expiry warning message is sent to the user when she logs in, starting at 14 days before the expiration date. On expiry, the administrator must re-set the expiry date in the configuration file in order to grant continued access. Expiry applies to all password types except "file" passwords. If passwd(5) files are being used for authentication, the "expires" field in the configuration file is not consulted. Instead, the daemon looks at the "shell" field of the password file entry for a valid expiry date. If Solaris shadow password files are used for authentication, the "expires" field in the configuration file is not consulted. The expiry field from the shadow password file (if it exists) is used as the expiration date. CONFIGURING AUTHENTICATION ON THE NAS ------------------------------------- On the NAS, to configure login authentication on all lines (including vty and console lines) aaa new-model aaa authentication login default tacacs+ NOTE: As soon as you issue this command, you will no longer be able to create new logins to your NAS without a functioning tacacs+ daemon appropriately configured with usernames and password, so make sure you have this ready. As a safety measure while setting up, we suggest you configure an enable secret and make it the last resort authentication method, so if your tacacs+ daemon fails to respond you will be able to use the NAS enable password to login. To do this, configure: enable secret foo aaa authentication login default tacacs+ enable If all else fails, and you find yourself locked out of the NAS due to a configuration problem, the section on "recovering from lost passwords" on Cisco's CCO web page will help you dig your way out. CONFIGURING ENABLE PASSWORDS ---------------------------- The default privilege level for an ordinary user on the NAS is usually 1. When a user enables, she can reset this level to a value between 0 and 15 by using the NAS "enable" command. If she doesn't specify a level, the default level she enables to is 15. You can enable via tacacs+ e.g. by configuring on the NAS: aaa authentication enable default tacacs+ then whenever you attempt to enable, an authentication request is sent with the special username $enab$ where is the privilege level you are attempting to enable to. (Note: in order to be compatible with earlier versions of tacacs, when the requested enable level is 15, the daemon will also try the username $enable$ before trying username $enab15$). For example, with the above declaration, in order to enable on the NAS, you need a user declaration like this one, on the daemon: user = $enab15$ { login = cleartext "the enable password for level 15" } Note: Be aware that this does have the side effect that you now have a user named $enab15$ who can then login to your NAS if she knows the enable password. Here is a similar declaration allowing users to enable to level 4: user = $enab4$ { login = des bsoF4OivQCY8Q } CONFIGURING AUTHORIZATION ------------------------- Authorization must be configured on both the NAS and the daemon to operate correctly. By default, the NAS will allow everything until you configure it to make authorization requests to the daemon. On the daemon, the opposite is true: The daemon will, by default, deny authorization of anything that isn't explicitly permitted. Authorization allows the daemon to deny commands and services outright, or to modify commands and services on a per-user basis. Authorization on the daemon is divided into two separate parts: commands and services. AUTHORIZING COMMANDS -------------------- Exec commands are those commands which are typed at a Cisco exec prompt. When authorization is requested by the NAS, the entire command is sent to the tac_plus daemon for authorization. Command authorization is configured by specifying a list of egrep-style regular expressions to match command arguments (see the supplied man page, regexp.3, for a full description of regular expressions) and an action which is "deny" or "permit". The following configuration example permits user Fred to run the following commands: telnet 131.108.13. and telnet 128..12.3 and show All other commands are denied (by default). user=fred { cmd = telnet { # permit specified telnets permit 131\.108\.13\.[0-9]+ permit 128\.[0-9]+\.12\.3 } cmd = show { # permit show commands permit .* } } NOTE: If an argument list you specify contains spaces or tabs, you must enclose it in double quotes. The command and arguments which the user types gets matched to the regular expressions you specify in the configuration file (in order of appearance). The first successful match performs the associated action (permit or deny). If there is no match, the command is denied by default. Conversely, the following configuration example can be used to deny the command: telnet 131.108.13. and permit all other arguments, since the last line will match any argument list. All other commands and services are permitted due to the "default service = permit" clause. Note: the default statement must be the first in the user clause user=fred { default service = permit cmd = telnet { # allow all fred's telnet commands except to 131.108.13.* deny 131\.108\.13\.[0-9]+ permit .* } } Note: Matches are not anchored, so "deny 131.108.13.[0-9]+" matches anywhere in the command. To anchor the match, use ^ at the beginning of the regular expression. Note: When a command has multiple arguments, users may enter them in many different permutations. It can be cumbersome to create regular expressions which will reliably authorize commands under these conditions, so administrators may wish to consider other methods of performing authorization e.g. by configuring NAS-local privileged enable levels on the NAS itself. COMMAND EXPANSION ----------------- For command authorization, the Cisco NAS expands all commands to their full names e.g. when you type "config t" on the NAS, this will be expanded to "configuration terminal" before being sent to the daemon so that you don't need to list all the possible contractions of a command. CONFIGURING DEFAULT AUTHORIZATION --------------------------------- There are 3 places where defaults for authorization may be configured. Unless specified to the contrary, the default is always to deny authorization. 1). To override the default denial of authorization for users who are not explicitly listed in the configuration file, the ersatz user DEFAULT, if defined, can be used for authorizing such users, viz: default authentication = file /etc/passwd user = DEFAULT { service = ppp protocol = ip { addr-pool=foobar } } In this example, users who do not appear elsewhere will be authenticated via the /etc/passwd file, and authorized by the contents of the user = DEFAULT entry. Note: For backward compatibility, the directive, default authorization = permit may still be specifed at the top level of the configuration file. This overrides the default denial of authorization for users who are not explicitly listed in the configuration file, permitting all authorization requests for such users. 2). At the user level i.e. inside the braces of a user declaration, the default for a user who doesn't have a service or command explicitly authorized is to deny that service or command. The following directive will permit the service or command by default instead: user = lol { default service = permit } NOTE: This directive must appear first inside the user declaration. 3). At the service authorization level i.e. inside the braces of a service declaration, arguments in an authorization request are processed according to the algorithm described later. Some actions when authorizing services (e.g. when matching attributes are not found) depend on how the default is configured. The following declaration changes the default from deny to permit for this user and service. user = lol { service = exec { default attribute = permit } } NOTE: This directive must appear before any others inside the service declaration. NOTE: for command authorization (as opposed to service authorization being discussed here), you specify deny .* or permit .* as the last line of the regular expression matches to create default behavior. AUTHORIZING EXEC STARTUP ------------------------- If you authorize some exec commands, you implicitly agree to allow that user to start an exec (it doesn't make sense to permit exec commands if an exec can't be started to run those commands) In addition to agreeing to allow an exec to start, you can supply some parameters whenever an exec starts e.g. an autocommand, a dialback string or a connection access list (acl). In the example below, when an exec is started on the NAS, an acl of 4 will be returned to the NAS: user=fred { # this following line permits an exec to start and permits # all commands and services by default default service = permit service = exec { # When an exec is started, its connection access list will be 4. # It also has an autocmd. acl = 4 autocmd = "telnet foobar" } cmd = telnet { # allow all fred's telnet commands except telnet to 131.108.13.* deny 131\.108\.13\.[0-9]+ permit .* } } NOTE: specifying an autocommand, or any other exec services, is part of EXEC AUTHORIZATION. For it to work, you must also configure exec authorization on your NAS e.g. aaa authorization exec tacacs+ AUTHORIZING EXEC, SLIP, PPP and ARAP SERVICES ---------------------------------------------- Authorizing exec, slip, PPP and arap services is done quite differently from command authorization. When authorizing these services, the NAS sends a request containing a number of attribute-value (AV) pairs, each having the form attribute=value (Note: during debugging, you may see AV pairs whose separator character is a "*" instead of a "=" sign. This is to signify that the value in a pair is optional. An "=" sign indicates a mandatory value. A "*" denotes an optional value). e.g. a user starting ppp/ip using an address of 131.108.12.44 would generate a request with the following AV pairs: service=ppp protocol=ip addr*131.108.12.44 You can use the NAS debugging command debug aaa authorization to see what authorization AV pairs are being used by the NAS. Note: If you are not on the router console, you will also need to issue a 'terminal monitor' command to see debug output. THE AUTHORIZATION PROCESS ------------------------- Authorizing a single session can result in multiple requests being sent to the daemon. For example, in order to authorize a dialin ppp user for IP, the following authorization requests will be made from the NAS: 1). An initial authorization request to startup ppp from the exec, using the AV pairs service=ppp, protocol=ip, will be made (Note: this initial request will be omitted if you are autoselecting ppp, since you won't know the username yet). This request is really done to find the address for dumb PPP (or SLIP) clients who can't do address negotiation. Instead, they expect you to tell them what address to use before PPP starts up, via a text message e.g. "Entering PPP. Your address is 1.2.3.4". They rely on parsing this address from the message to know their address. 2). Next, an authorization request is made from the PPP subsystem to see if ppp's LCP layer is authorized. LCP parameters can be set at this time (e.g. callback). This request contains the AV pairs service=ppp, protocol=lcp. 3). Next an authorization request to startup ppp's IPCP layer is made using the AV pairs service=ppp, protocol=ipcp. Any parameters returned by the daemon are cached. 4). Next, during PPP's address negotiation phase, each time the remote peer requests a specific address, if that address isn't in the cache obtained in step 3, a new authorization request is made to see if the peers requested address is allowable. This step can be repeated multiple times until both sides agree on the remote peer's address or until the NAS (or client) decide they're never going to agree and they shut down PPP instead. As you can see from the above, a program which plans to handle authorization must be able to handle a variety of requests and respond appropriately. AUTHORIZATION RELIES ON AUTHENTICATION -------------------------------------- Since we pretty much rely on having a username in authorization requests to decide which addresses etc. to hand out, it is important to know where the username for a PPP user comes from. There are generally 2 possible sources 1). You force the user to authenticate by making her login to the exec and you use that login name in authorization requests. This username isn't propagated to PPP by default. To have this happen, you generally need to configure the "if-needed" method, e.g. aaa authentication login default tacacs+ aaa authentication ppp default if-needed 2). Alternatively, you can run an authentication protocol, PAP or CHAP (CHAP is much preferred), to identify the user. You don't need an explicit login step if you do this (so it's the only possibility if you are using autoselect). This authentication gets done before you see the first LCP authorization request of course. Typically you configure this by doing: aaa authentication ppp default tacacs+ int async 1 ppp authentication chap If you omit either of these authentication schemes, you will start to see authorization requests in which the username is missing. CONFIGURING SERVICE AUTHORIZATION --------------------------------- A list of AV pairs is placed in the daemon's configuration file in order to authorize services. The daemon compares each NAS AV pair to its configured AV pairs and either allows or denies the service. If the service is allowed, the daemon may add, change or delete AV pairs before returning them to the NAS, thereby restricting what the user is permitted to do. The complete algorithm by which the daemon processes its configured AV pairs against the list the NAS sends, is given below. The Authorization Algorithm --------------------------- Find the user (or group) entry for this service (and protocol), then for each AV pair sent from the NAS: If the AV pair from the NAS is mandatory: a). look for an exact attribute,value match in the user's mandatory list. If found, add the AV pair to the output. b). If an exact match doesn't exist, look in the user's optional list for the first attribute match. If found, add the NAS AV pair to the output. c). If no attribute match exists, deny the command if the default is to deny, or, d). If the default is permit, add the NAS AV pair to the output. If the AV pair from the NAS is optional: e). look for an exact attribute,value match in the user's mandatory list. If found, add DAEMON's AV pair to output. f). If not found, look for the first attribute match in the user's mandatory list. If found, add DAEMONS's AV pair to output. g). If no mandatory match exists, look for an exact attribute,value pair match among the daemon's optional AV pairs. If found add the DAEMON's matching AV pair to the output. h). If no exact match exists, locate the first attribute match among the daemon's optional AV pairs. If found add the DAEMON's matching AV pair to the output. i). If no match is found, delete the AV pair if the default is deny, or j). If the default is permit add the NAS AV pair to the output. k). After all AV pairs have been processed, for each mandatory DAEMON AV pair, if there is no attribute match already in the output list, add the AV pair (but add only ONE AV pair for each mandatory attribute). RECURSIVE AUTHORIZATION ----------------------- Remember that authorization is also recursive over groups, in the same way that password lookups are recursive. Thus, if you place a user in a group, the daemon will look in the group for authorization parameters if it cannot find them in the user declaration. EXAMPLES -------- key = "your key here" user=fred { login = des mEX027bHtzTlQ name = "Fred Flintstone" member = administrators expires = "May 23 2005" arap = cleartext "Fred's arap secret" chap = cleartext "Fred's chap secret" service = exec { # When Fred starts an exec, his connection access list is 5 acl = 5 # We require this autocmd to be done at startup autocmd = "telnet foo" } # All commands except show system are denied for Fred cmd = show { # Fred can run the following show command permit system deny .* } service = ppp protocol = ip { # Fred can run ip over ppp only if he uses one # of the following mandatory addresses. If he supplies no # address, the first one here will be mandated addr=131.108.12.11 addr=131.108.12.12 addr=131.108.12.13 addr=131.108.12.14 # Fred's mandatory input access list number is 101 inacl=101 # We will suggest an output access list of 102, but the NAS may # choose to ignore or override it optional outacl=102 } service = slip { # Fred can run slip. When he does, he will have to use # these mandatory access lists inacl=101 outacl=102 } } user = wilma { # Wilma has no password of her own, but she's a group member so # she'll use the group password if there is one. Same for her # password expiry date member = admin } group = admin { # group members who don't have their own login password will be looked # up in /etc/passwd login = file /etc/passwd # group members who have no expiry date set will use this one expires = "Jan 1 1997" } USING PROGRAMS TO DO AUTHORIZATION ---------------------------------- There are some limitations to the authorization that can be done using a configuration file. The main ones are that you're constrained by the algorithm the daemon uses, and that the configuration is basically static, so if you're trying to use it to allocate dynamic things (such as addresses from a pool) that vary over time, you need another mechanism. One solution is to arrange for the daemon to call your own user-supplied programs to control authorization. These "callouts" permit almost complete control over authorization, allowing you to read all the fields in the authorization packet sent by the NAS including all its AV pairs, and to set authorization status and send a new set of AV pairs to the NAS in response. USING AV PAIRS FOR AUTHORIZATION -------------------------------- During authorization, the NAS sends an authorization request packet containing various fields of interest and a set of AV pairs (see the tacacs+ protocol specification for a list of fields and pairs). Fields from the authorization packet can be supplied to the programs you call on their command line, by using the appropriate dollar variables in the configuration file (see below). AV pairs from the authorization packet are fed to the program's standard input, one per line. The program is expected to process the AV pairs and write them to its standard output, one per line. What happens then is determined by the exit status of the program. NOTE: AV pairs are text strings with the format attribute=value. Unlike the configuration file which allows spaces when specifying AV pairs, there should be no spaces surrounding the "=" sign when using the programmatic interface. CALLING SCRIPTS BEFORE AUTHORIZATION ------------------------------------ You can specify a per-user program to be called before any other attempt to authorize is made by using a "before" clause e.g. user = auth1 { before authorization "/usr/local/bin/pre_authorize $user $port $address" } The AV pairs sent from the NAS will be supplied to this program's standard input, one pair per line. Fields from the initiating authorization packet which the NAS sends to the daemon can also be passed to the program by using dollar variables in the command line. A complete list of available variables is as follows (consult the API specification for more details). user -- user name name -- Nas name port -- Nas port address -- Nac address (remote user location) priv -- privilege level (a digit, 0 to 15) method -- (a digit, 1 to 4) type -- (a digit, 1 to 4) service -- (a digit, 1 to 7) status -- (pass, fail, error, unknown) Unrecognized variables will appear as the string "unknown". If the program returns a status of 0, authorization is unconditionally permitted. No further processing is done on this request and no AV pairs are returned to the NAS. If the program returns a status of 1, authorization is unconditionally denied. No further processing is done on this request and no AV pairs are returned to the NAS. If the program returns a status of 2, authorization is permitted. The program is expected to modify the AV pairs that it receives on its standard input (or to create entirely new ones) and to write them, one per line, to its standard output. The new AV pairs will be sent to the NAS with a status of AUTHOR_STATUS_PASS_REPL. No further processing takes place on this request. If the program returns a status of 3, authorization is denied, but all attributes returned by the program via stdout are returned to the NAS. Also, whatever the program returns on stderr is placed into the server-msg field and returned to the NAS as well. Any other status value returned from the program will cause an error to be returned to the NAS. Note that a status of 2 is not acceptable when doing command authorization. CALLING PROGRAMS AFTER AUTHORIZATION ------------------------------------ You can specify a per-user program to be called after authorization processing has been carried out by the daemon (but before the authorization status and AV pairs have been transmitted to the NAS). The program can optionally modify the AV pairs being sent back to the NAS and change the authorization status if required. group = auth1 { # call /usr/local/bin/post_authorize passing it the username, port # and current authorization status. after authorization "/usr/local/bin/post_authorize $user $port $status" } The AV pairs resulting from the authorization algorithm that the daemon proposes to return to the NAS, are supplied to the program on standard input, one AV pair per line, so they can be modified if required. Fields from the incoming authorization packet which the NAS sent to the daemon can also be passed to the program on its command line by specifying dollar variables in the command line (see previous section). The program is expected to process the AV pairs and write them to its standard output, one per line. What happens then is determined by the exit status of the program: If the program returns a status of 0, authorization continues as if the program had never been called. Use this if e.g. you just want a program to send mail when an authorization occurs, without otherwise affecting normal authorization. If the program returns a status of 1, authorization is unconditionally denied. No AV pairs are returned to the NAS. No further authorization processing occurs on this request. If the program returns a status of 2, authorization is permitted and any AV pairs returned from the program on its standard output are sent to the NAS in place of any AV pairs that the daemon may have constructed. Any other value will cause an error to be returned to the NAS by the daemon. WARNINGS AND CAUTIONS --------------------- Customers attempting to write authorization scripts will find the NAS debugging command "debug aaa authorization" invaluable. Pre and post authorization programs are invoked by handing the command line to the Bourne shell. On many Unix systems, if the shell doesn't find the specified program it returns a status of one, which denies authorization. However, at least one Unix system (BSDI) returns a status code of 2 under these circumstances, which will permit authorization, and probably isn't what you intended. Note also that if your program hangs, the authorization will time out and return an error on the NAS, and you'll tie up a process slot on the daemon host, eventually running out of resources. There is no special code to detect this in the daemon. Unless you make special arrangements, the daemon will run as root and hence the programs it invokes will also run as root, which is a security weakness. It is strongly recommended that you use absolute pathnames when specifying programs to execute, and that you use the Makefile options TACPLUS_USERID and TACPLUS_GROUPID so that the daemon is not running as root when calling these programs, The daemon communicates with pre and post authorization programs over a pair of pipes. Programs using the standard i/o library will use full buffering in these circumstances. This shouldn't be a problem for most programs, since they'll read AV pairs till they see end of file on input, and they'll flush all output when they exit. Note that when avpairs containing spaces are listed in the configuration file, you need to enclose them in double quotes so that they are parsed correctly. Avpairs which are returned via standard output do not need delimiters and so should not be enclosed in double quotes. CONFIGURING AUTHORIZATION ON THE NAS ------------------------------------ If authorization is not explicitly configured on the NAS, no authorization takes place i.e. effectively, everything is permitted. Note that this is the converse of what happens on the daemon, where anything not explicitly permitted is denied by default. To configure command authorization on the NAS, issue the following NAS configuration commands: aaa authorization commands 1 tacacs+ aaa authorization commands 15 tacacs+ This will make the NAS send tacacs+ requests for all level 1 (ordinary user) and level 15 (privileged level) commands on all lines/interfaces. NOTE: As soon as you configure the above on your NAS, you will only be permitted to execute NAS commands which are permitted by your tacacs+ daemon. So make sure you have configured, on the daemon, an authenticated user who is authorized to run commands, or you will be unable to do much on the NAS after turning on authorization. Alternatively, or in addition, you may also want to configure the following: aaa authorization commands 1 tacacs+ if-authenticated This will use tacacs+ authorization for level 1 (user-level commands) but if problems arise, you can just switch off the tacacs+ server and authorization will then be granted to anyone who is authenticated. The following daemon configuration should be sufficient to ensure that you can always login as username "admin" (with a suitable password) and run any command as that user: user = admin { default service = permit login = des kppPfHq/j6gXs } ACCOUNTING ----------- There is only one configurable accounting parameter -- the accounting file name. All accounting records are written, as text, to this filename. The filename is configured as follows at the top-level of the configuration file: accounting file = Since accounting requests occur (and are serviced) asynchronously, it is necessary to lock the accounting file so that two writers don't simultaneously update it. The daemon uses the fcntl call to do this locking, so it is recommended that the accounting file reside on a local filesystem. Although fcntl locking over NFS is supported on some Unix implementations, it is notoriously unreliable. Even if your implementation is reliable, locking is likely to be extremely inefficient over NFS. NAS CONFIGURATION ----------------- To get accounting records equivalent to previous versions of tacacs, the following is sufficient. "Stop" records contain elapsed time for connections and exec sessions. aaa accounting network stop-only tacacs+ aaa accounting exec stop-only tacacs+ CONFIGURING CALLBACK WITH TACACS+ --------------------------------- Note: Callback is available only in IOS 11.1 and later, and can only be controlled via Tacacs+ for ASYNC lines. ISDN callback can be configured on the NAS but cannot be controlled via AAA. Here is an example of AAA configuration (with exec and network accounting enabled): NAS configuration: aaa new-model tacacs-server host XX.XX.XX.XX tacacs-server key fookey aaa accounting exec wait-start tacacs+ aaa accounting network wait-start tacacs+ ! Example of AAA configuration for Exec: aaa authentication login execcheck tacacs+ aaa authorization network tacacs+ service exec-callback : line 4 login authentication execcheck ! Example of AAA configuration for ARAP: aaa authentication arap arapcheck tacacs+ aaa authorization network tacacs+ arap callback : line 4 arap authentication arapcheck ! Example of AAA-specific configuration for PPP callback: aaa new-model aaa authentication ppp pppcheck tacacs+ aaa authorization network tacacs+ : int async 6 ppp authentication chap pppcheck ppp callback accept Daemon configuration: Example of remote TACACS+ server CONFIG file entry for username `foobar': user = foobar { arap = cleartext AAAA login = cleartext LLLL chap = cleartext CCCC pap = cleartext PPPP opap = cleartext OOOO service = ppp protocol = lcp { callback-dialstring=123456 } service = arap { callback-dialstring=2345678 } service = exec { callback-dialstring=3456789 callback-line=7 nocallback-verify=1 } } DEBUGGING CONFIGURATION FILES ----------------------------- When creating configuration files, it is convenient to check their syntax using the -P flag to tac_plus e.g. tac_plus -P -C will syntax check the configuration file and print any error messages on the terminal. DEBUGGING A RUNNING SERVER -------------------------- There is a myriad of debugging values that can be used in conjunction with the -d flag to produce debugging output in @TACPLUS_LOGFILE@. For example, starting the daemon with tac_plus -C CONFIG -d 16 will put authentication debugging into @TACPLUS_LOGFILE@. You can view this information by using the tail command. tail -f @TACPLUS_LOGFILE@ See the man page for more information. CHANGING CONFIGURATIONS ----------------------- To change a configuration file, you must edit the configuration file and then send the daemon a SIGUSR1. This will cause it to reinitialize itself and re-read the configuration file. On startup, tac_plus creates the file @TACPLUS_PIDFILE@, if possible, containing its process id. If you invoke the daemon so that it listens on a non-standard port, the file created is @TACPLUS_PIDFILE@. instead, where is the port number the daemon is listening on. Assuming you are listening on the default port 49, something like the following should work: # kill -USR1 `cat @TACPLUS_PIDFILE@` It's a good idea to check that the daemon is still running after sending it a SIGUSR1, since a syntactically incorrect configuration file will cause the daemon to die. NOTE: The perl script generate_passwd.pl may be used to hand-generate encrypted passwords, or they may be taken from a Unix passwd file. CANNED CONFIGURATIONS --------------------- Here are some canned configurations for getting demos started: 1). A canned configuration for login authentication only. This allows user fred to login with password "abcdef". If the tacacs+ server dies, the enable secret will be accepted as a login password instead. DAEMON: key = # repeat as necessary for each user user = fred { login = cleartext abcdef } NAS: aaa new-model enable secret foobar ! use tacacs+. If server dies, use the enable secret password aaa authentication login default tacacs+ enable tacacs-server host tacacs-server key 2). A canned configuration for command authorization. This will allow user fred to login with password abcdef and to run the privileged (level 15) commands 'write terminal' and 'configure'. All other privileged commands will be denied. The "none" keyword in the NAS configuration line means that if the tacacs+ server dies, any command will be allowed. DAEMON: key = # repeat as necessary for each user user = fred { login = cleartext abcdef cmd = write { permit terminal } cmd = configure { permit .* } } NAS: aaa new-model ! all level 15 (privileged commands). If server dies, allow everything aaa authorization commands 15 tacacs+ none tacacs-server host tacacs-server key 3). Canned configuration for network access authorization. This config allows "fred" to login to line 1 with password abcdef (or to and to run ppp using chap authentication. The chap password is "lab". DAEMON: key = # repeat as necessary for each user user = fred { login = cleartext abcdef chap = cleartext lab service = ppp protocol = ip { addr=1.0.0.2 } } NAS: aaa new-model ! authenticate exec logins (if not autoselecting) aaa authentication login default tacacs+ ! authorize network services via tacacs+ aaa authorization network tacacs+ ! use tacacs+ for authenticating ppp users aaa authentication ppp default tacacs+ tacacs-server host tacacs-server key interface Async1 ip address 1.0.0.1 255.0.0.0 async default ip address 172.21.14.55 encapsulation ppp async dynamic address async mode interactive ! use chap to authenticate ppp users ppp authentication chap line 1 ! need "modem inout" here and flow control if using a modem 4). Canned configuration for ARAP. NAS: aaa new-model aaa authentication arap default guest tacacs+ aaa authorization network tacacs+ aaa accounting network start-stop tacacs+ ! appletalk routing arap network ! interface Ethernet0 appletalk cable-range appletalk zone ! tacacs-server host tacacs-server key ! line 1 location a modem modem answer-timeout 0 modem InOut autoselect arap autoselect during-login arap enable speed flowcontrol hardware Daemon: key = "some key" user = lol { arap = cleartext service = arap { } } Authorization AV pairs ---------------------- The following authorization AV pairs are supported by 10.3(3) onwards except where specifically noted. The following AV pairs specify which service is being authorized. They are typically accompanied by protocol AV pairs and other, additional pairs from the lists below. service=arap service=shell (for exec startup, and also for command authorizations) service=ppp service=slip service=system (not used). service=raccess Used for managing reverse telnet connections e.g. user = jim { login = cleartext lab service = raccess { port#1 = nasname1/tty2 port#2 = nasname2/tty5 } } Requires IOS configuration aaa authorization reverse-access tacacs+ See the IOS docs for more details. protocol=lcp The lower layer of PPP, always brought up before IP, IPX, etc. is brought up. protocol=ip Used with service=ppp and service=slip to indicate which protocol layer is being authorized. protocol=ipx Used with service=ppp to indicate which protocol layer is being authorized. protocol=atalk with service=ppp or service=arap protocol=vines For vines over ppp. protocol=ccp Authorization of CCP. Compression Control Protocol). No other av-pairs associated with this. protocol=cdp Authorization of CDP (Cisco Discovery Protocol). No other av-pairs associated with this. protocol=multilink Authorization of multilink PPP. See 'max-links' and 'load-threshold'. protocol=unknown For undefined/unsupported conditions. Should not occur under normal circumstances. cmd (EXEC) If the value of cmd is NULL e.g. the AV pair is cmd=, then this is an authorization request for starting an exec. If cmd is non-null, this is a command authorization request, It contains the name of the command being authorized e.g. cmd=telnet cmd-arg (EXEC) During command authorization, the name of the command is given by an accompanying "cmd=" AV pair, and each command argument is represented by a cmd-arg AV pair e.g. cmd-arg=archie.sura.net NOTE: 'cmd-arg' should never appear in a configuration file. It is used internally by the daemon to construct a string which is then matched against the regular expressions which appear in a cmd clause in the configuration file. acl (ARAP, EXEC) For ARAP this contains an access-list number. For EXEC authorization it contains an access-class number, e.g. acl=2. which is applied to the line as the output access class equivalent to the configuration command line access-class 2 out An outbound access-class is the best way to restrict outgoing telnet connections. Note that a suitable access list (in this case, numbered 2) must be predefined on the NAS. inacl (PPP/IP/IPX) This AV pair contains an IP or IPX input access list number for slip or PPP e.g. inacl=2. The access list itself must be pre-configured on the Cisco box. Per-user access lists do not work with ISDN interfaces unless you also configure a virtual interface. After 11.2(5.1)F, you can also use the name of a predefined named access list, instead of a number, for the value of this attribute. Note: For IPX, inacl is only valid after 11.2(4)F. inacl# (PPP/IP, PPP/IPX, 11.2(4)F) This AV pair contains the definition of an input access list to be installed and applied to an interface for the duration of the current connection, e.g. inacl#1="permit ip any any precedence immediate" inacl#2="deny igrp 0.0.1.2 255.255.0.0 any" Attributes are sorted numerically before they are applied. For IP, standard OR extended access list syntax may be used, but it is an error to mix the two within a given access-list. For IPX, only extended access list syntax may be used. See also: sho ip access-lists sho ip interface sho ipx access-lists sho ipx interface debug aaa author debug aaa per-user outacl (PPP/IP, PPP/IPX) This AV pair contains an IP or IPX output access list number for SLIP. PPP/IP or PPP/IPX connections e.g. outacl=4. The access list itself must be pre-configured on the Cisco box. Per-user access lists do not work with ISDN interfaces unless you also configure a virtual interface. PPP/IPX is supported in 11.1 onwards only. After 11.2(5.1)F, you can also use the name of a predefined named access list, as well as a number, for the value of this attribute. outacl# (PPP/IP, PPP/IPX, 11.2(4)F) This AV pair contains an output access list definition to be installed and applied to an interface for the duration of the current connection, e.g. outacl#1="permit ip any any precedence immediate" outacl#2="deny igrp 0.0.9.10 255.255.0.0 any" Attributes are sorted numerically before they are applied. For IP, standard OR extended access list syntax may be used, but it is an error to mix the two within a given access-list. For IPX, only extended access list syntax may be used. See also: sho ip access-lists sho ip interface sho ipx access-lists sho ipx interface debug aaa author debug aaa per-user addr (SLIP, PPP/IP) The IP address the remote host should be assigned when a slip or PPP/IP connection is made e.g. addr=1.2.3.4 routing (SLIP, PPP/IP) Equivalent to the /routing flag in slip and ppp commands. Can have as its value the string "true" or "false". timeout (11.0 onwards, ARAP, EXEC) Sets the time until an arap or exec session disconnects unconditionally (in minutes), e.g. timeout=60 autocmd (EXEC) During exec startup, this specifies an autocommand, like the autocommand option to the username configuration command, e.g. autocmd="telnet foo.com" noescape (EXEC) During exec startup, this specifies "noescape", like the noescape option to the username configuration command. Can have as its value the string "true" or "false", e.g. noescape=true nohangup (EXEC) During exec startup, this specifies "nohangup", like the nohangup option to the username configuration command. Can have as its value the string "true" or "false", e.g. nohangup=true priv-lvl (EXEC) Specifies the current privilege level for command authorizations, a number from zero to 15 e.g. priv_lvl=5. Note: in 10.3 this attribute was priv_lvl i.e. it contained an underscore instead of a hyphen. zonelist (ARAP) An Appletalk zonelist for arap equivalent to the line configuration command "arap zonelist" e.g. zonelist=5 addr-pool (11.0 onwards, PPP/IP, SLIP) This AV pair specifies the name of a local pool from which to get the IP address of the remote host. Note: addr-pool works in conjunction with local pooling. It specifies the name of a local pool (which needs to be pre-configured on the NAS). Use the ip-local pool command to declare local pools, e.g on the NAS: ip address-pool local ip local pool foo 1.0.0.1 1.0.0.10 ip local pool baz 2.0.0.1 2.0.0.20 then you can use Tacacs+ to return addr-pool=foo or addr-pool=baz to indicate which address pool you want to get this remote node's address from, e.g. on the daemon: user = lol { service = ppp protocol = ip { addr-pool=foo } } route (11.1 onwards, PPP/IP, SLIP). This AV pair specifies a route to be applied to an interface. During network authorization, the "route" attribute may be used to specify a per-user static route, to be installed via Tacacs+. The daemon side declaration is: service=ppp protocol=ip { route=" [ ]" } This indicates a temporary static route that is to be applied. ", and []" are expected to be in the usual dotted-decimal notation, with meanings the same as for the familiar "ip route" configuration command on a NAS. If gateway is omitted, the peer's address is taken to be the gateway. The route is expunged once the connection terminates. route# (PPP/IP/IPX, 11.2(4)F) Same as the "route" attribute, except that these are valid for IPX as well as IP, and they are numbered, allowing multiple routes to be applied e.g. route#1="3.0.0.0 255.0.0.0 1.2.3.4" route#2="4.0.0.0 255.0.0.0" or, for IPX, route#1="4C000000 ff000000 30.12.3.4" route#2="5C000000 ff000000 30.12.3.5" See also: sho ip route sho ipx route debug aaa author debug aaa per-user callback-rotary (11.1 onwards, valid for ARAP, EXEC, SLIP or PPP) The number of a rotary group (between 0 and 100 inclusive) to use for callback e.g. callback-rotary=34. Not valid for ISDN. callback-dialstring (11.1 onwards, valid for ARAP, EXEC, SLIP or PPP) sets the telephone number for a callback e.g. callback-dialstring=408-555-1212. Not valid for ISDN. callback-line (11.1 onwards, valid for ARAP, EXEC, SLIP or PPP) The number of a tty line to use for callback e.g. callback-line=4. Not valid for ISDN. nocallback-verify (11.1 onwards, valid for ARAP, EXEC) Indicates that no callback verification is required. The only valid value for this parameter is the digit one i.e. nocallback-verify=1. Not valid for ISDN. idletime (11.1 onwards, EXEC) Sets a value, in minutes, after which an IDLE session will be terminated. N.B. Does NOT work for PPP. tunnel-id (11.2 onwards, PPP/VPDN) This AV pair specifies the username that will be used to authenticate the tunnel over which the individual user MID will be projected. This is analogous to the "NAS name" in the "vpdn outgoing" command. ip-addresses (11.2 onwards, PPP/VPDN) This is a space separated list of possible IP addresses that can be used for the end-point of the tunnel. In 11.2(5.4)F, this attribute was extended as follows: 1) comma (',') is also consider as a delimiter For example the avpair can now be written as ip-addresses = 172.21.9.26,172.21.9.15,172.21.9.4 2) '/' is considered a priority delimiter. When you have a number of Home Gateway routers, it is desirable to consider some as the primary routers and some as backup routers. The '/' allow you to config the routers into priority groups, so that the NAS will try to forward the users to the high priority routers, before forwarding to the low priority one. For example in the following avpair: ip-addresses = "172.21.9.26 / 172.21.9.15 / 172.21.9.4" 172.21.9.26 is considered to be priority 1 172.21.9.15 is considered to be priority 2 172.21.9.4 is considered to be priority 3 The NAS will try to forward the users to 172.21.9.26, before trying 172.21.9.15. If the NAS can't forward users to 172.21.9.26, it will try 172.21.9.15 next. If it fails with 172.21.9.15, it will then try forwarding to 172.21.9.4. source-ip (PPP/VPDN, now deprecated, only existed in releases 11.2(1.4) thru 11.2(4.0.2)). This specifies a single ip address will be used as the source of all VPDN packets generated as part of the VPDN tunnel (see the equivalent source-ip keyword in the IOS vpdn outgoing command). nas-password (PPP/VPDN, 11.2(3.4)F, 11.2(4.0.2)F) During L2F tunnel authentication, nas-password specifies the password for the NAS. gw-password (PPP/VPDN, 11.2(3.4)F, 11.2(4.0.2)F) During L2F tunnel authentication, gw-password specifies the password for the home gateway. rte-ftr-in# (PPP -- IP/IPX, 11.2(4)F) This AV pair specifies an input access list definition to be installed and applied to routing updates on the current interface, for the duration of the current connection. For IP, both standard and extended Cisco access list syntax is recognised, but it is an error to mix the two within a given access-list. For IPX, only Cisco extended access list syntax is legal. Attributes are sorted numerically before being applied. For IP, the first attribute must contain the name of a routing process and its identifier (except for rip, where no identifier is needed), e.g. rte-fltr-in#0="router igrp 60" rte-fltr-in#1="permit 0.0.3.4 255.255.0.0" rte-fltr-in#2="deny any" For IPX, no routing process is needed, e.g. rte-fltr-in#1="deny 3C01.0000.0000.0001" rte-fltr-in#2="deny 4C01.0000.0000.0002" See also: show ip access-lists show ip protocols sho ipx access-lists sho ipx interface debug aaa author debug aaa per-user Related IOS commands: IP: router [no] distribute-list in IPX: ipx input-network-filter rte-ftr-out# (PPP/IP, 11.2(4)F) This AV pair specifies an input access list definition to be installed and applied to routing updates on the current interface, for the duration of the current connection. For IP, both standard and extended Cisco access list syntax is recognised, but it is an error to mix the two within a given access-list. Attributes are sorted numerically before being applied.

During IPCP address negotiation, if an ip pool name is specified for a user (see the addr-pool attribute), a check is made to see if the named pool is defined on the NAS. If it is, the pool is consulted for an ip address. If the required pool is not present on the NAS (either in the local config, or as a result of a previous download operation), then an authorization call to obtain it is attempted, using the special username: -pools where is the configured name of the NAS. Note: This username can be changed using the IOS configuration directive e.g. aaa configuration config-name nas1-pools-definition.cisco.us The pool-def attribute is used to define ip address pools for the above authorization call e.g. user = foo { login = cleartext lab service = ppp protocol = ip { addr-pool=bbb } } user = nas1-pools { service = ppp protocol = ip { pool-def#1 = "aaa 1.0.0.1 1.0.0.3" pool-def#2 = "bbb 2.0.0.1 2.0.0.10" pool-def#3 = "ccc 3.0.0.1 3.0.0.20" pool-timeout=60 } } In the example above is a configuration file fragment for defining 3 pools named "aaa", "bbb" and "ccc" on the NAS named "nas1". When the user "foo" refers to the pool named "bbb", if the pool "bbb" isn't defined, the NAS will attempt to download the definition contained in the "nas1-pools" entry. The other pools will also be defined at the same time (or they will be ignored if they are already defined). Since this procedure is only activated when an undefined pool is referenced, one way to redefine a pool once it has been downloaded is to manually delete the definition e.g. by logging into the NAS, enabling, and configuring: config t no ip local pool bbb ^Z When a pool is deleted, there is no interruption in service for any user who is currently using a pool address. If a pool is deleted and then subsequently redefined to include a pool address that was previously allocated, the new pool will pick up the allocated address and track it as expected. Since downloaded pools do not appear in the NAS configuration, any downloaded pool definitions automatically disappear whenever a NAS reboots. These pools are marked as "dynamic" when they appear in the output of the "show ip local pools" NAS command. Since it is desirable not to have to manually delete pools to redefine them, the AV pair pool-timeout= can be used to timeout any downloaded pool definitions. The timeout is in minutes. The effect of the pool-timeout attribute is to start a timer when the pool definitions are downloaded. When the timer expires, the pools are deleted. The next reference to a deleted pool via will cause a re-fetch of the pool definitions. This allows pool changes to be made on the daemon and propagated to the NAS in a timely manner. See also: sho ip local pool sho ip local pool IOS commands: ip local pool old-prompts (PPP/SLIP) This attribute is integrated into the following IOS images: 11.2(7.4)P 11.2(7.4) 11.1(13.1) 11.(16.2) 11.1(13.1)AA 11.1(13.1)CA 11.1(13.1)IA 11.2(8.0.1)F 11.0(16.2)BT) This attribute allows providers to make the prompts in T+ appear identical to those of earlier systems (tacacs and xtacacs). This will allow administrators to upgrade from tacacs/xtacacs to T+ transparently to users. The difference between the prompts is as follows: In xtacacs, when the user types "slip" or "ppp" the system prompts for an address followed by a password, whereas T+ prompts only for an address. In xtacacs, if the user types "slip host" or "ppp host", the system prompts for a password. In T+, there is no prompt. Using this attribute, T+ can be made to mimic the prompting behaviour of xtacacs, by configuring network authorization on IOS, and using the "old-prompts=true" attribute value pair for slip and ppp/ip, viz: user = joe { global = cleartext foo service = exec { } service = slip { default attribute = permit old-prompts=true } service = ppp protocol = ip { default attribute = permit old-prompts=true } } i.e. the prompts are controlled by the addition of the "old-prompts=true" attribute. max-links (PPP/multilink - Multilink parameter; 11.3) This AV pair restricts the number of multilink bundle links that a user can have.
