How To Kick Everyone From A Counter Strike Source Server
1. Place Buffer1.cfg and Buffer2.cfg in your cfg folder. If it doesn't exist, make it (see below)
(Commonly C:\User\program files\steam\steamapps\Account name\counter-strike source\cstrike\cfg)
2. Go in game, open the developer's console, and type in the following (you may change bind key):
Bind M "wait;exec Buffer1;exec Buffer2"
(If developer's console doesn't open, go to options, keyboard, advanced, enable developer's console)
3. Go in game and rapidly hit the M key to crash the server. Depending on how fast you hit it, it should
take anywhere from 15-30 seconds to crash. Don't stop hitting the key until you get a message:
"Client # has overflowed reliable channel."
