agreed, it is much easier to alt+tab out of game, and click a players name, and click kick/ban rather than entering a string command in the console in game imo.

What is the cvar to take control over the server in-game then? rcon_password xxxxx something?

It could be useful until I get this program set up properly.

I've not tried this yet myself and I haven't seen a list of tried and tested rcon commands for C2 but here are the commands for C1:

Login as admin while in-game, you will need to then type the following in rcon
rcon_connect addr:[your server ip] port:[rcon port] pass:[rcon pass]
con_restricted 0

Get the list of players in the server
rcon_command status

Bans player for (ban_timout) minutes from server. [See ban_timeout]
rcon_command ban "[player name here] "

Removes player from ban list
rcon_command ban_remove "[player name here] "

Shows currently banned players
rcon_command ban_status

Ban timeout in minutes
rcon_command ban_timeout 30

Kicks player from game
rcon_command kick "[player name here] "

Kicks client with slot a slot from game.
rcon_command kickid [slot number]

Kills the player
rcon_command kill "[player name here] "

sv_gamerules
rcon_command sv_gamerules "PowerStruggle"

Change the map
rcon_command map [map name here]

Restart the round
rcon_command sv_restart

Switch to next level in rotation or restart current one
rcon_command g_nextlevel

Notify players of the next map to play
rcon_command net_next_map

Broadcasts a server message to all players in the server
rcon_command sv_say "[messag here] "

Thanks alot. I'll give it a try.
