RANCiD is a "Really Awesome New Cisco confIg Differ" developed to
maintain CVS (or Subversion or git) controlled copies of router configs.

*** The Following Information is Very Important ****
Rancid 3.0 converts several device scripts (the remaining will follow) to
libraries used by the single script, named rancid, to parse device output.
It also requires perl 5.10 minimum.  Also see the UPGRADING file.

Rancid 2.3 introduces a new directory layout.  It has been changed to more
closely follow the standard path hierarchy, which is defined by the FHS
standard and autoconf, and/or make these locations more easily configurable
within rancid.

The obvious advantage of this is making rancid more easily packagable; i.e.:
NetBSD pkgsrc, FreeBSD port, Linux RPM, etc.

Please please please please read the UPGRADING file for more information.

The following (non-exhaustive list) are included as part of the installation
and configuration tools:

Makefile.am	processed by automake to produce Makefile.in
Makefile.in	processed by configure to produce Makefile
acinclude.m4	sets some GNU autoconf options
aclocal.m4	Output of GNU autoconf script

depcomp		part of GNU autoconf
install-sh	GNU autoconf shell script to simulate BSD style install
missing		part of GNU autoconf
mkinstalldirs	GNU autoconf shell script to make installation directories

rancid will also need to have the following packages:
gnudiff		gnudiff provides the uni-diff (-u) option.  If you do not have
		a diff that supports -u, configure will set-up rancid to use
		'diff -c' or 'diff -C'.
perl5		perl version 5.10 or greater available from www.cpan.org
expect		http://expect.nist.gov/  We highly suggest that you stick to
		expect 5.24.1 (or so).  This seems to work best.  Note that
		you need to have the accompanying tcl &/ tk.
tcl		Required by expect.

and, rancid will also need to have one of the following packages; your choice:
cvs		Code revision system available from prep.ai.mit.edu:/pub/gnu
git		Code revision system, an alternative to cvs.  Use the configure
		option --with-git to configure for git.
svn		Code revision system, an alternative to cvs.  Available from
		http://subversion.tigris.org/tarballs/.  Use the configure
		option --with-svn to configure for Subversion.
		To convert from CVS to SVN, find the cvs2svn python script,
		then:
		cd ~rancid
		cvs2svn --trunk= --trunk-only -s `pwd`/.svn --keywords-off \
			`pwd`/CVS
		sh -c '. /path/to/etc/rancid.conf ; for g in $LIST_OF_GROUPS; \
			do svn co file://`pwd`/.svn/$g; done'

Bill Fenner (now maintained by others) has a cgi script for interacting
with CVS repositories via a web interface.  This provides a great way to
view rancid diffs and full configs, especially for those unfamiliar with
cvs.  There are similar tools for Subversion and git.  The package is not
included, but can be found here:

	http://www.freebsd.org/projects/cvsweb.html


Quick Installation Guide (an example):

1) ./configure [--prefix=<basedir>]
   By default, rancid will be installed under /usr/local/rancid (the default
   "prefix").  This can be overridden with the --prefix option.  E.g.:

	./configure --prefix=/home/rancid

   Rancid uses autoconf's "localstatedir" as the location of it's logs,
   CVS, Subversion or git respository, and directories where it's groups are
   placed.  The user who will run rancid (from cron, etc) will need write
   access to these directories.  By default, this is <prefix>/var, or
   /home/rancid/var following the example above.

   We realize that this is not optimal, but it follows the standards.  We
   suggest that this be altered to include the package name, like so:

	./configure --prefix=/home/rancid \
			--localstatedir=/home/rancid/var/rancid

   The user who will run rancid must have write permission in "localstatedir".

   See ./configure --help for other configure options, including which SCM
   should use.  Now is the time to choose the SCM..

2) make install

   If rancid is being installed in system locations, then the install will
   likely need to be done as root.  eg:

   make; sudo make install

3) Modify <sysconfdir>/rancid.conf (e.g.: <basedir>/etc/rancid.conf).  The
   variable LIST_OF_GROUPS is a space delimited list of router "groups".
   E.g.:
	LIST_OF_GROUPS="backbone aggregation switches"

4) Put .cloginrc in the home directory of the user who will run rancid.
   .cloginrc must be not be readable/writable/executable by "others",
   i.e.: .cloginrc must be mode 0600 or 0640.

5) Modify .cloginrc.

   Test to make sure that you can log into every router.  The login scripts
   support options m and M to help debug the .cloginrc; see clogin(1).

   Note: the JunOS that user you use *must* log into a cli shell (which
   is the default on a juniper), not a unix shell.

   See the file cloginrc.sample, located in <datadir> (<basedir>/share/rancid),
   for examples and a good starting point.  Also take a look at the cloginrc
   manual page, 'man -M <basedir>/man cloginrc'.

   See the cloginrc(5) manpage.

6) Modify /etc/aliases
   Rancid sends the diffs and other administrative emails to rancid-<GROUP>
   and problems to rancid-admin-<GROUP>, where <GROUP> is the "GROUP" of
   routers.  This way you can separate your backbone routers from your
   access routers or separate based upon network etc...  Different router
   uses forced different people being interested in router "groups" -
   thus this setup.  Make sure email to rancid-<GROUP> works.  /etc/aliases
   can be maintainable by Majordomo or another maillist software or may just
   forward to a remote machine, but make sure the user that runs rancid can
   post to the list.

   The Precedence header set to bulk or junk and setting the other RFC3834
   auto-responder headers *hopefully* avoids replies from auto-responders and
   other vacation type mail filters.

   The --enable-mail-plus option to configure will set each of the "rancid-"
   addresses mentioned above to "rancid+".  See sendmail's operation manual
   for more information on handling of '+'.

   The --enable-adminmail-plus configure option will set each of the
   "rancid-admin-" addresses mentioned above to "rancid-admin+".  If this
   option is not used, the value of --enable-mail-plus is assumed.  That is,
   the addresses will be "rancid+", if it is specified.

   There are several mail-related options in rancid.conf.

   See the rancid.conf manpage.  Also see the manual for your MTA to
   determine the format of and procedure for adding aliases.

7) Run rancid-cvs.
   This creates all of the necessary directories and config files for
   each of the groups in LIST_OF_GROUPS and imports them into CVS (or
   Subversion or git).  This will also be run each time a new group is added.
   Do not create the directories or CVS repository manually, allow rancid-cvs
   to do it.  Also see 'man -M <basedir>/man rancid-cvs'.

8) For each "group", modify the router.db file in the group directory.
   The file is of the form "router;mfg;state" where "router" is
   the name (we use FQDN) of the router, mfg is the manufacturer
   from the set of (cat5|cisco|juniper) (see router.db.5 for a complete
   list and description), and "state" is either up or down.  Each router
   listed as "up" will have the configuration grabbed.  Note: manufacturer
   cat5 is intended only for cisco catalyst switches running catalyst (not
   IOS) code.

   e.g.: <localstatedir>/<group>/router.db:
	cisco-router.domain.com;cisco;up
	adc-mux.domain.com;ezt3;up
	foundry-switch-router.domain.com;foundry;up
	juniper-router.domain.com;juniper;up
	redback-dsl-router.domain.com;redback;down
	extreme-switch.domain.com;extreme;down

9) For first-time users or new installations, run bin/rancid-run (with no
   arguments) and check the resulting log file(s) (in logs/*) for errors.
   Repeat until there are no errors.

10) Put rancid-run in cron to be called however often you want it to
   run for each group (rancid-run [<GROUP>]).  If you run it less
   often than once/hour, check the setting of OLDTIME in etc/rancid.conf.
   E.g.:
	# run config differ hourly
	1 * * * * <BASEDIR>/bin/rancid-run
	# clean out config differ logs
	50 23 * * * /usr/bin/find <localstatedir>/logs -type f -mtime +2 -exec rm {} \;

11) Note: If you are using any of these programs (other than rancid-run) out
    of cron or from a shell, make sure that you set your $PATH correctly so
    that they work.  E.g.: if you are using clogin, it can call id, telnet,
    ssh, and/or rsh.

    configure already makes sure that $PATH is set correctly in
    etc/rancid.conf for rancid-run, so you could use the $PATH from there. e.g.:

	50 23 * * * . <sysconfdir>/rancid.conf; clogin -c 'sh vers' router

12) Send any bugs, suggestions or updates to rancid@shrubbery.net.
    See the web page at http://www.shrubbery.net/rancid.  We have
    created the standard mailing lists for those interested;
    rancid-announce@shrubbery.net and rancid-discuss@shrubbery.net.
    Subscribe by sending an email whose body contains "subscribe
    rancid-<announce or discuss>" to majordomo@shrubbery.net.

    If you are reporting problems, please include the version of rancid,
    expect, and your OS in the email.


Problem with clogin/telnet hanging within rancid or scripts?

If you have experienced rancid (or more precisely, telnet) hanging on a
solaris 2.6 box; check to be sure you have the following two o/s patches
installed (see showrev -p).  There may be more recent versions of these
patches and they are likely included with 2.7 and 2.8: 

Patch-ID# 105529-08
Keywords: security tcp rlogin TCP ACK FIN packet listen
Synopsis: SunOS 5.6: /kernel/drv/tcp patch

Patch-ID# 105786-11
Keywords: security ip tcp_priv_stream routing ip_enable_group_ifs ndd
Synopsis: SunOS 5.6: /kernel/drv/ip patch

Another contributor to rancid "hanging", with or without the o/s patches
mentioned above, is a bug in expect/tcl.  We've noticed that expect (from
5.24.1 forward), and whatever tcl happens to compile with it, exhibits a
problem on Linux and Solaris where rancid's scripts hang waiting for input
from the device.  Patches to expect are available on the rancid web page.

Also, for rancid 2.3 and later, changes were made to the login scripts
which use some more elaborate regexes that have failed with expect versions
prior to 5.40.  While 5.40 works, it still seems to need the patch offered
on the rancid web page for Linux and Solaris.

See www.shrubbery.net/rancid for additional notes on this.  Also the
UPGRADING file that comes with the distribution.
