How to save Steam ID bans in CS:S

What it does

Without this, bans vanish on restart. Add exec banned_user.cfg to server.cfg to load them.

The game's own description: Writes a list of permanently-banned user IDs to banned_user.cfg.

Run it on your server

On a SLASHPLAY server, type it in the Console tab of the server page; the reply shows right under it. A value set there lasts until the server restarts. To keep it, add the line to cstrike/cfg/server.cfg. New to this? Start a CS:S server first.
