Hmmm, someone already figured something out what kind of protocol and stuff they are using to query game- or masterservers!?

I already did some packet-sniffing but everything looks strange.

Please share your knowledge when you found something out, thank you :)

yes I have informations about this stuff.
practically of2 seems to use the Quazal network and so all the packets exchanged between client and server are encrypted with an algorithm that I reversed some weeks ago and for which I wrote a script for quickbms.

I have attached the decrypted and encrypted versions of the packets (first client query and first server reply, the data continues but I choosed only the first 2 for my example) you had in the dump you attached to your message.

I'm not fully sure if the data you collected is of another server or the connection with the master server for retrieving the server's list (because the data decrypted is a bit unusual from the classica "server's info"), anyway it's all there.
