Just curious if there is a way to turn off the crond logging to /var/log/messages. It already logs to /var/log/cron and frankly I'm sick of messages getting to be 168Mb every two days. So I am trying to disable everything that logs worthless or redundant info and cron is the biggest culprit. Already disabled named logging which was another culprit.

Thanks in advance.

Which logger do you use?
You can likely set up a filter to send the messages to /dev/null rather than /var/log/messages

I use syslog. In the syslog.conf it shows:

*.info;mail.none;authpriv.none;cron.none /var/log/messages

Which if I am not mistaken means its not supposed to log any cron messages in messages....but it does?!? A broken cron perhaps?

EDIT: Turns out the message it coming from pam whenever cron runs... is there a way to turn off pam reporting cron jobs without adding auth.none to the exclusion list...that's pretty important info generally except when cron does it.

Also if anyone knows how to completely eliminate all "last message repeated" messages would be handy. I only care if it ever happened and don't want any repeat messy-ges.
