run more than one server on a pc at a time ?
 

Maybe one of you all can help me. Every time i try to run a second server i get this message from steam "Failed to start game (app already running)." Is there a work around for it as i would like to host at lest 3 more servers for this game on my linux box

free standing server needed and you will have to run it on different ports

If you have the capability to virtualize and a powerful enough server, you could run 3 different VMs on 3 different IPs.

Otherwise you will need a bunch of different port sets, and a powerful physical machine.

If you're going to host servers download SRCDS. As far as I recall, SRCDS allowed you to bypass most of steam to run a server. Also, don't VM your servers, you would waste a huge amount of system resources running virtual machines your host system. SRCDS is capable of binding to separate IPs, assuming your system has them bound. Otherwise you can use the -port flag to set an unique port on each server.
