I am trying to use the packet sniffer example in the examples folder of the GWCA repository

I am looking to identify a specific packet, which I don't believe there is a header for yet. I know it's a dumb question - can someone explain to me, step by step, how I would go about using this packet sniffer? Or, if there is a better option, how I would go about sniffing all GStoC packets?
Any help is much appreciated
