What it does

The standard port is 27015. Set it on the launch line with -port when running several servers on one machine.

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 game/csgo/cfg/server.cfg. New to this? Start a CS2 server first.
