How do you make a dedicated server?

How do you make a server where you can leave and the server will still be there?

Can anyone please tell me?

(they call it a dedicated server.)

That's not what a dedicated server is. A dedicated server is when you start a game, but a player object isn't created for you, you're only able to work the game's console.

Use the -dedicated command line parameter. If you want it to actually advertise on the master server, I think you also have to use +internetserver 1.

Everything else you want the game to do for you, you can stick it in adedserv.cfg. Like autoexec.cfg, it autoruns when the game starts, except only in dedicated servers.

I think internetserver uses - as well, + is for things to run in the console, like skin and color.

Command line parameters are prefixed by -, and you can execute any console commands you want by prefixing them with +, yes. But I wasn't sure if there was actually a -internetserver parameter, as I've never hosted a dedicated server.

Thanks for telling me.

Neo, it is -internetserver.
