The problems to date have been related to executing the CGI's (ala
http://64.233.187.104/search?q=cache:npfOizO28JIJ:www.meulie.net/forum_v
iewtopic.php%3F21.729+nagios+selinux&hl=en) but it would still be my
first, best guess as to the cause of your problem. You'll probably find
messages in one of your system log files containing with "avc:  denied
..." with the specific reason for the denial. I'd suggest you take a
look at
http://fedora.redhat.com/docs/selinux-apache-fc3/sn-debugging-and-custom
izing.html#sn-policy-debugging, specifically at audit2allow to help
determine policy changes.

You're the first that I know of to have problems with external commands.
I don't use SELinux so I can't be specific but perhaps those links, plus
http://fedora.redhat.com/docs/selinux-apache-fc3/ will be useful to you.
Perhaps someone else who uses SELinux can chime in as well.

If you do determine that it's SELinux that's the problem, a synopsis
back to the list for the archives would be useful.

Thanks,

If you're going to leave SELinux enabled you should probably understand
more about it than just how it affects Nagios.
