To run the Half-Life/TFC decidated linux server, unpack the hlds_l3103.tar.gz file into a directory on your server. If you have the 3.1.0.1 or 3.1.0.2 version installed, you can just unpack hlds_l3103upgrd.tar.
Replies to halflife clients (or mods) that send out LAN game requests, imforming them of multiple hlds servers that are running. Great for LAN parties.
