Source Code. Help needed
 

Hello, i am writing a paper for university in which i try to get some information about the gnutella-net.

I am especially interested in an analysis concerning the ping, pong, query and queryreply messages.
In order to get these informations i would like to adapt the soucecode.

Unfotunately i have less experience in programming and am learning while writing this paper.

It would help me a great deal, if someone could tell me, which class or methods would be the best to start with.

Right now i am trying to find a position in the soucecode where the messages, passing my client, are read (maybe already identified as ping-, pong-, oder querymessage) and i can catch them and wirte them down into a file.

Thank you very much in advance.
