Reading from ports using sockets

basically you got many programs connected to ports. What I need help on is connecting to one of those ports of my choice and reading data that comes through.

sl lets say this program voice.exe is running on port 2982. I can set it up so I can see whats coming out of my site on voice.exe and see if my ip adresses is going through etc.

You need to set your NIC in promiscuous mode to listen to the traffic that passes over it, then you can inspect the data yourself.
