Hi

I need to develop a program that firstly, it opens the pcap file and then it should detect the p2p protocol or Traffic.Would u please guide me exactly that how can i detect the p2p protocols or traffic?

Of course I ve read that base on port and app signature we can identify it but port is not reliable coz it is changing all the time but I think signature is more trusting...So my second Q is how can I get the app or p2p signature from the pcap files?

Even if some one has the any implementation about itI would be so grateful to see the source code.

Thanks in advance
