I see a lot of people don’t know how to setup their dedicated servers and this is a pity because bad settings have as a result bad mood to the players 
So, here’s a sample script for people that want to setup a linux (or win) dedicated server:
paste the following lines into a startup.sh file (and make it executable afterwards with a chmod a+x startup.sh):
screen -m -d
/usr/local/games/enemy-territory-test/etded
+set com_hunkmegs 256
+set com_zonemegs 32
+set dedicated 2
+set sv_pure 1
+set sv_maxRate 15000
+set sv_hostname “Hostname”
+set sv_punkbuster 1
+set g_teamforcebalance 1
+set g_dowarmup 0
+set match_minplayers 1
+set g_antilag 1
+map fueldump
dedicated controls if your server will show up in the main server list. 1 not to show, 2 to show up.
g_dowarmup controls if that “press F3 to start” message shows up before starting the match.
