[Bug-XBoard] ICS protocol

[Jan Rummens]

Hi,

 

I’m doing some research for documenting the ICS protocol to better understand how FICS and ICC protocols behave. I did some reading on the web, but didn’t find any relevant documentation. I did some snooping on my network during a chess game and found some interesting stuff (see details below). Some of it is obvious by looking at it, but other isn’t, like these sequences -1 1 1 1 1 0 28, 3 1 1 1 1 0 28,… and 1 20 12 39 39 1200 1200 and 0 0 0.. etc. These and other things I would like to know. For example I see nowhere in my communication between myclient and server port 5000 the individual moves, only what I get back from the server (as listed below; does it use a different port for the individual moves?). First aim is to understand the client/server communication of a game.

Could you point me to some detailed writings (I already have the server code) or somebody that could answer my question?

 

 

Thanks,

Jan Rummens.
