I recently shut down my old HLDS control panel that allowed some basic features for linux servers running Half-Life based games and mods:
-Start/Restart/Stop running server
-Uploading for maps and auto entry to map cycle
-In web editing of configuration and map cycle files
I plan to restart this project and add some more features if there is a market for software like this still. I have been out of the half life game server scene for a while since I was at school but I am willing to retake this project if there are companies looking for a cheaper solution.
Let me know. Best way is to email me or send me a message on AIM.
