Any suggestions on what to run on a centos box to verify that the
server isn't compromised or being sniffed?  Thanks!

For "isn't compromised", you need a host integrity verification system like
Tripwire or AIDE (which is in the base repo). Expect to have to tweak the
config to cover the stuff you've got installed.

You can detect sniffing by checking for promiscuous interfaces on the LAN -
use proDETECT (http://sourceforge.net/projects/prodetect/) or a similar
tool for this purpose.

Alternatively, if you have the time and resources, you could run a
full-blown network intrusion detection system like Snort
