Call Of Duty: Black Ops 1

for admins:

...\Steam\steamapps\common\call of duty black ops\main\myFile.cfg
rcon host <IP>:<PORT>
rcon login <PASSWORD>
rcon teamstatus

...\Steam\steamapps\common\call of duty black ops\players\config_mp.cfg
bind L "rcon teamstatus"
bind O "exec myFile"

make config_mp.cfg read only or your changes will be lost. You will not be able to rename your classes, when the file is read-only. You can rename, but after the next game start the classes have the old names. This does not effect the class data like guns.

remember:

/rcon clientkick <ID>
/rcon banclient <ID>

<ID> is the first column from teamstatus
