Solved it myself. Think it was an SELINUX problem. When I created the .cfg file under my id, having su'ed to root, I got the problem. When I deleted and recreated the .cfg file having logged in as root directly, the problem went away.

I get the following error on one of my MRTG config files when I run it from a cron job. I do not get the error when I run it from the command line. I have plenty of other config files run from the same cron job that run just fine.

ERROR: writing /etc/mrtg/00255520WLC1.ok.ok: Permission denied at /usr/bin/../lib64/mrtg2/MRTG_lib.pm line 1580.

Anyone seen this before?
