How to Ban Players on Your Counter-Strike 2 Server

Ban players by SteamID or IP on your CS2 dedicated server using banid, banip, banned_user.cfg, and banned_ip.cfg.

CS2 inherits the Source ban system. Bans are applied with console/RCON commands and persisted to two files in game/csgo/cfg/:

Ban a Player by SteamID

Find the player's user ID with the status command (RCON or console).

Run:

banid <minutes> <userid>

<minutes> of 0 = permanent. Example: banid 0 12 permabans user ID 12.

Save the ban list to disk so it persists across restarts:

writeid

Find the user ID with status.

Run:

banip <minutes> <userid>

Save:

writeip

Make sure your server.cfg ends with:

exec banned_user.cfg
exec banned_ip.cfg
writeid
writeip

This loads the lists every time the server starts.

removeid <steamid>
writeid

removeip <ip>
writeip

You can also edit banned_user.cfg / banned_ip.cfg in the Files manager. Each line follows this format:

banid 0 STEAM_1:0:12345678

Stop the server before editing to avoid being overwritten by writeid/writeip.
