There is also a german interview with the coder ... hereFAQ wrote: How can I enable BattlEye protection on my game server?
Start BattlEye (on your system, not on the server), go to Admin->Add Server and enter the required server RCon data (not your BF2CC account data!). Click OK and wait for a confirmation to pop up. If succeeded, your game server is now being protected by the BE Master Server. You can close BattlEye now.
How can I disable BattlEye protection on my game server?
Do the same as ^, but this time go to Admin->Remove Server.
How can I play on a BE-protected game server?
Just start BattlEye and join the server.
What happens if a player doesn't run BattlEye / cheats on my BE-protected server?
A server message is displayed that all players can see ingame.
What means the message "Violation #X detected"?
It means that a hack has been detected on the player's system.
Chances are that these violations are caused by memory corruptions other than cheats/hacks, e.g. by game-hooking applications or a virus. But either way, the player has to make sure that his system & BF2 is clean (note: BF2 mods are no problem at all!) - if he is not able to, he can't/mustn't play.
