Even though there is some information on how to setup a dedicated server source server on a Linux based system the articles are often old or to generic for my liking. I have written this article to help other people setup a Day of Defeat source (DOD:S) server on a Ubuntu 8.04.1 system.
Downloading the software from steampowered.com
The first thing to do is to download the Source Dedicated Server from steampowered. So on the linux server I create a folder on the dod user account and download the binary with the following commands.
dod@dirac:~$ mkdir srcds_l dod@dirac:~$ cd srcds_l dod@dirac:~/srcd_l$ wget http://www.steampowered.com/download/hldsupdatetool.bin
