Re: [rancid] router config diffs

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
