MRTG Permission Denied

I do not believe there are two mrtg cron jobs running. The errors I'm collecting are being logged to a file that I've listed in the cron job.

I've updated the cron job to put mrtg.ok into /tmp/. Since there are no timestamps in the log, I'll note that my log file last updated 1/5 at 1:00.

Hi John,
Do you have SELinux enabled?
Let's check:

Code: Select all

# sestatus

Vinh,

We do not have SELinux enabled.

Thanks .... now I understand that you do have SELinux turned on.

Moving the mrtg.ok and mrtg.lock files to /tmp/ looks to have resolved the permissions issue.

This topic can be closed. Thanks
