CrashBlock is a lightweight plugin which prevents two commonly known Source server crashing techniques. Simply named "the RCON method" and "connecting command approach".

The plugin is designed to provide a stop gap against server crashers whilst zBlock 4.5 is still in development.

This plugin will not be compatible with other plugins which attempt to combat these crash techniques - i.e. zBlock 4.5 Beta or RconLock.

Further we would like to advise server administrators to set strong rcon passwords as there are a few people reporting their server passwords are being discovered by brute-force attacks. For added security you may also set this password through a startup command-line parameter.
