Problem
Is there some basic utility to open a specific network TCP port on my machine? I need to test how my program deals with ports in the listening state.

Fix for: Utility to open TCP port to listen state
Low Risk
netcat should do what you want. Have it listen on you machine and echo stuff to STDOUT: when you want it to close when the connection ends, don't use -k
