ZDoom

Right now I have the latest version of GZDoom from this repository http://debian.drdteam.org/ using a copy of DOOM II. What I want to do is make it so that it is a headless server with no server player that doesn't require a graphics device. How do i go about doing this? Optional, but I would also like it to be a 24/7 server with automatic games so that I don't have to interact with it.

Short answer: You can't because GZDoom doesn't work that way.

Longer answer: GZDoom's net code does not have a concept of "servers." Everybody is a peer. There is an arbitrator, but only in the sense that whoever entered the "host" command is in charge of changing maps, server cvars, etc. Because GZDoom requires you to have all players present that will be in the game at the time the game starts, and there is no in-game joining, running a 24/7 server would in fact require all players to leave the game running indefinitely.

You will probably want Zandronum instead.

Thanks, I'll check it out.
