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)?

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".

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

why? there are 3 manners of affecting the same result, but without modifying
the installed base and without needing to remember that change following the
next upgrade. embrace the unix methodology - assemble (pipe) simple tools
for complex results.

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.

FILTER_PWDS
Determines which passwords will be filtered from configs.

I don't want anything filtered from rancid; it's just email where I
want passwords to be filtered out. Maybe I could figure out how to
set DIFFSCRIPT to accomplish that, but I already had a script for
blanking out sensitive info for when the security office or whoever
wants to do an audit & demands a copy of all the configs. So I could
add a few lines to control_rancid and call a script I already knew
worked or spend who knows how long trying to figure how to set
DIFFSCRIPT .. and expediency won.

Lee

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.

Regards,
Lee
