I am making a small presentation on battle.net protocol, bnetd and reverse engineering.
I would need someone with original W3 to get Wireshark, start a live capture, login to original W3 server and join a channel. Once you do this, save the packet dump and send it to me in a PM.
If you'd like to help but don't know how to use wireshark I can help you over Teamviewer.
It would be greatly appreciated.
