It seems like nagios user is not allowed to run cron jobs... Do you have cron.allow or cron.deny on this system?

Code: Select all

cat /etc/cron.allow
cat /etc/cron.deny

What the the permissions on /usr/bin/crontab?

Code: Select all

ls -l /usr/bin/crontab

Can you also run the following command and show the output?

Code: Select all

grep nosuid /etc/fstab

I added nagios to cron.allow
Still dont see the cron running.

Below are the output details :

Code: Select all

cat /etc/cron.allow
root
nagios

cat /etc/cron.deny

[lmiltchev]

Have you tried restarting crond after adding nagios to the /etc/cron.allow?

Code: Select all

service crond restart

Try this or better yet, restart the server (if this is possible at the moment) to see if this is going to fix the issue. If the issue is still present, check the logs for clues one more time:

Code: Select all

tail -50 /var/log/cron
tail -50 /var/log/secure

There must be a mod that you made while hardening this server, that prevents nagios to run cron jobs. Do you remember what changes have you made? Also, make sure that fixes that you are trying are not reverted automatically by Puppet.

Seems like cron failed because nagios user did not have a home dir.
I created one manually, all crons seem to work fine now.

Thanks a lot for your assistance.
