IP ports

[John]

I'm trying to test a network application that I developed
and I think some other process has the UDP port that I am
expecting to use. Is there a tool that will show me which
processes have IP ports open and which port they have?

www.kerio.com have a free firewall that shows what ports are open and
sending/listening

Maybe SysInternals' TCP View does what you want.

netstat -a -o

gives a list of ports, and the process ID, which you can then lookup in
taskmanager, but TCPView from SysInternals is probably better.
