Well, first you have to set a static IP on your server (assuming it is behind a NAT router). Next you must do port-forwarding on your router to port 7777/UDP and optionally 7787/UDP if you will be advertizing the server globally. Install & patch the UT2004 server binaries and install any extra map packs you might want. Next you configure your ~/.ut2004/System/UT2004.ini to suit your server's needs. Finally, launch the server as un unprivileged user. To start my UT2004 Onslaught server, I have a tiny little script like the following:
Code:
#!/bin/sh
cd /usr/local/games/ut2004/System/
./ucc-bin server ONS-ArcticStronghold?game=Onslaught.ONSOnslaughtGame
The server can be fine-tuned from the web interface, which can be enabled in that UT2004.ini I mentioned earlier. It runs on port 8000 by default, but you don't have to forward any ports for that unless you plan on accessing the web console from outside of your LAN.
