Oh no please so its not so with Quake III dedicated!
 

Please dont tell me that I have to stay logged into SSH in order for my Quake server to run? I logged out of putty and noticed my server went offline, I logged back into putty and ran the quake server.cfg command and my server came back up. Please do not say that I have to leave my putty window open for Quake to run :( Is there another way to keep the quake server running without logging out of SSH?

Ok, I was told by email to do this:

you can use the "screen" command to run the server in a detached screen and
thus it won't close when you exit.

Just add "screen" in front of the command to load the server binary.

i.e. "screen -dmS quakeserver ./quake"

However when I run the screen command it says screen is not a valid command. What am I doing wrong?
