I play a lot of online games.. And I've already found a lot of "cracks" for them online.. but then I saw myself in front of 2 problems:

1. None of them work on LINUX plataforms (and I hate Windows);
2. None of them are "perfect".

So, I'd like to build one by myself.

I know that these kind of games run on an client-server system. And, when I click, for exemple, on the screen to "use an item" like eating some food, the client sends a COMMAND (probably a function) to the server, and then the server identify the command, run the process, and send back the action.

So, the point is.. Im using UBUNTU. I'd like to know, if there's any way to IDENTIFY the COMMAND that is sent when I do the action, while the program is running. I don't know if I made myself clear, but I hope so =P.

Or, If u don't know, if u could suggest any website, tuturials, e-books or something where I could find such answers...

Thanks in advance for the help.

Hugs!!
