[rancid] router config diffs

Post by Wayne Eisenberg
I just upgraded from 3.1 to 3.8, and all of a sudden I am getting emails every time there is a change in the config - 'router config diff' emails. I must have tweaked something in the previous version so that I wasn't getting them for every change in config, but I don't remember what. Is there a switch or conf variable that can turn it off? I just want to be notified if rancid can't contact a device.

please see the FAQ S2 Q4. your cvs working directory is most likely out
of sync somehow.

Hi,

I'm using SVN, not CVS.

I probably didn't do a good job of explaining. I'm not getting the same diff over and over. They are new versions, valid diffs. I don't see how svn could get out of sync, when the crontab was inactive (everything rem'ed out) so there was no activity during the upgrade. Before the upgrade, I know there were router config changes taking place and I did not get an email about them. Now I do. So I'm hunting for how to turn the notifications off.

I'm also noticing a .cvsignore file in the 'configs' folder in WebSVN. Not sure why that is there or if I should care. It wasn't there before the upgrade.

Thanks,
Wayne

I'd go with changing control_rancid. Search for

# Mail out the diffs (if there are any).
if [ -s $TMP.diff ] ; then

which looks like the line to change to turn notifications off. Or
check the FAQ:
Q. I just want to store configrurations, I do not want to receive diffs. How
can I accomplish this?
A. Use procmail to filter them out of your inbox.
OR, redirect the mail aliases in your MTA's aliases file or database to a
mailman list with no subscribers.
OR, redirect the mail aliases to /dev/null.
OR, set DIFFSCRIPT in rancid.conf to something that eats it's input, such
as "dd of=/dev/null bs=16k".

Ja. or if it is a diff repeatedly of something that ought to be ignored,
share examples.

Bingo. I found my tweak. Thanks, Lee! Instead of actually sending the email, I had just redirected it to /dev/null.

Maybe that could be a config choice in rancid.conf (if it were a global switch) or .cloginrc (if you wanted to turn off mail for specific devices or groups)?

Thanks, that's an interesting idea although what I was really thinking of was turning off the emailing of diffs, not totally disabling mail. (It would still be important to know if rancid lost contact with devices.)
If that were part of the official control_rancid, then it could be controlled by a variable in the rancid.conf file. Just a newbie idea.

For a global switch just use your version of sendmail instead of the system version:
$ cat sendmail
#!/bin/sh
#
# rancid insists on having sendmail
# so give it one
#
echo "" >> /tmp/sendmail.txt
date >> /tmp/sendmail.txt
echo "$*" >> /tmp/sendmail.txt
while read LINE
do
echo $LINE >> /tmp/sendmail.txt
done
echo "" >> /tmp/sendmail.txt

altho you'd probably want it to be just
exit

and if you ever want rancid to actually send mail, have your sendmail be a link to the real one.

Lee

I haven't tried this, but it sure looks like one could build rancid with
export SENDMAIL=/usr/local/bin/sendmail_alt
./configure --prefix= ..etc..

and have /usr/local/bin/sendmail_alt be just
exit

and that would take care of not sending emails or doing something
other than sending mail. Yes? but that means you'd have to build
rancid instead of just installing from some repository..

In any case, I went with changing control_rancid because there were a
few other things I wanted to do like filtering out passwords, keys,
hashes, etc. from the mail msg before sending it. So right after the
# Diff the directory and then checkin.
section I added

# -LR- begin: remove passwords, etc. from diff listing
/usr/local/bin/sanitize.sh $TMP.diff >$TMP.diff2
/bin/mv $TMP.diff2 $TMP.diff
# -LR- end : remove passwords etc. from diff listing

youre making that more difficult than necessary,

export SENDMAIL="dd of=/dev/null bs=32k"

but, you still want the admin email, imiho, and that will break it.

this too is possible without changing control_rancid; see rancid.conf(5)
for FILTER_PWDS & DIFFSCRIPT.
