[rancid] Need Help

[Harsha S Aryan]

hi,

below is my rancid config, i am unable to config files of my network device
as attachment in mail

can any one let me know how do i do.

cat /etc/rancid/
rancid.conf .rancid.conf.swp
***@Nagios:~# cat /etc/rancid/rancid.conf

#
# Under BASEDIR (i.e.: --localstatedir), there will be a "logs" directory
for
# the logs from rancid and a directory for each group of routers defined in
# LIST_OF_GROUPS (below). In addition to these, there will be a "CVS"
# directory which is the cvs (or Subversion) repository.
#
# Use a full path (no sym-links) for BASEDIR.
#
TMPDIR=/tmp; export TMPDIR
# Be careful changing this, it affects CVSROOT below. It should be a FQPN,
not
# relative.

# If RCSSYS is svn, this can be:
# - an (absolute) path (a subdirectory of BASEDIR by default).
# - any URL that subversion understands, but beware that:
# - no attempt will be made to create the repository when running
rancid-cvs.
# - authentication credentials, if necessary, MUST be cached (see the SVN
# book, Ch. 3, Network Model, Caching credentials) before
non-interactive
# commands can run, e.g. by running rancid-cvs after installation.

these
# requires manual conversions.

# be sure to read ../README regarding aliases.
#
# If your MTA configuration is broken or you want mail to be forwarded to a
# domain not the same as the local one, define that domain here. "@" must
be
# included, as this is simply appended to the usual recipients. It is NOT
# appended to recipients specified in rancid-run's -m option.

# By default, rancid mail is marked with precedence "bulk". This may be

setting
# it to "" or adding X- style headers. Individual headers must be separated
# by a \n.

device as attachment in mail

There is a tested series of steps for making rancid work under Ubuntu
14.04 here:
https://nsrc.org/workshops/2015/wacren-nmm/raw-attachment/wiki/Agenda/rancid-exercise.htm

If you follow those steps, it will work. Or if you get a problem, at
least you can point to exactly the step where it didn't work as expected.

One thing I see wrong in your config is this:

LIST_OF_GROUPS="switches"
LIST_OF_GROUPS="routers"

It's a single setting, so it should be:

LIST_OF_GROUPS="switches routers"

However that doesn't explain any permissions problems you might see. If
you get these you are probably running rancid as the wrong user, or
perhaps you ran rancid once as root, which will break all the
permissions required for it to be able to run as the rancid user
subsequently. If so you may be able to fix this using:

sudo chown -R rancid:rancid /var/lib/rancid

HTH,

Brian.

OK, then I can't help you - the code is open source, so find the bit
where it sends the mail, and modify it. You were already given the clue
for this: find where the code uses the SENDMAIL setting.

cd /path/to/rancid/source/code
grep -R SENDMAIL .

Regards,

Brian.

Actually:

grep -R MAILHEADERS .

works better for me (looks like rancid 2.3.6 doesn't have a SENDMAIL
setting). This will get you to the following bit of code:

# Mail out the diffs (if there are any).
if [ -s $TMP.diff ] ; then
(
echo "To: $mailrcpt"
echo "Subject: $subject"
echo "$MAILHEADERS" | awk '{L = "";LN = $0;while (LN ~ /\\n/)
{ I = index(LN,"\\n");L = L substr(LN,0,I-1) "\n";LN =
substr(LN,I+2,length(LN)-I-1);}print L LN;}'
echo ""
if which diffstat >/dev/null; then
diffstat $TMP.diff
fi
cat $TMP.diff
) | sendmail -t
fi

Brian.

if you use the alpha code, 3.2.99, you can set SENDMAIL in rancid.conf,
as i described in the previous message.
