This post has two intents: 1. Pose a question and find solution. 2. Warn others of an individual suspected of running said hack. Because the question is valid and the reporting of the individual may be taken as a witch hunt, I'll keep the two issues apart.
We had an individual come onto our server today and was quite disruptive. When we went to ban the player through in-game commands, PRoCon and console commands, we found there was no means to accomplish this. In-game commands and PRoCon returned no confirmation and the individual remained active in game. BC2 console commands also returned no confirmation. PB console returned a "ban failed" message. We suspect this was due to the individual's name, which is rather unique and listed below, or the individual was using a hack. Further, the individual had been previously banned by name some months prior yet was able to re-enter the server. Killing, kicking and banning were unresponsive through any means. In short, we were unable to exert any control over the player aside from moving him from attacker to defender and back. After two or three minutes of that, the player finally left. What would cause this and what do you suggest as means to avoid this in the future? We have manually added the individual to our ban list via name (again), GUID and IP. We'll see how useful that is.
For those interested, the individual's name is -_-_-_-___--~_- and the
last 8 of the GUID are 967bd8a6.
