I am trying to determine the root of an issue I am having. How can I watch traffic destined to a specific port on my CentOS 5.1
box to see if its even hitting it? It would be udp traffic.

If you're using IPTABLES on your CentOS box, then you can "watch" the traffic hit your rules using "watch -d iptables -nvL". The -d will highlight changes (so you can spot them) and you should see the number of packets change as each packet is processed by your rules.
If you have a specific chain name that deals with your port, then add that after the -nvL in the command - e.g. "watch -d iptables -nvL myChain"
