Can you decode bnet server packages? about gowarcraft3 HOT 6 CLOSED

The Battle.net protocol for WC3 has changed since patch 1.30.2 (released a few months ago), which means a lot of Battle.net code in this repository is outdated and will only work for private servers such as PvPGN.

For now, you can still decode packets for ladder games (see w3gsdump), but I assume that might change in the future if Blizzard gets around to updating the game protocol as well. Look at https://github.com/dethredic/WC3StreamerOverlay for a project that uses this approach and does what you're describing in point 1.

I'm not aware of a solution that lets you edit packets on the wire, pcap only lets you capture and observe them.

I'm afraid this repo will not be too useful for you in that case. Battle.net stuff has been kept to a minimum, and it's mostly just chat functionality at the moment. For the quick game features, I think you get far by configuring/editing PvPGN.

Yeah, you can indeed intercept packets and act as a man-in-the-middle, but the Warcraft client tries to verify that it's communicating with official servers (which is why you need w3l to connect to PvPGN and why gproxy uses LAN functionality by default).

Before 1.30.2, there's a RSA verification of the server IP. After 1.30.2, there's a TLS server certificate verification. If you want the client to connect to a non-official server (i.e. PvPGN or your intercept program), you need to disable these checks, which is what w3l does, you can't disable them by altering packets.

Thanks for the assistance!
