Gamespy did drop the online DH2005 servers. There are still lots of players they gone very sad becoz of this. No one can see others online servers now.
I have found openspy.org webpage , they host this game server but not working. They have in general webpage and servers problem. I was thinking to host this game on my own server for the users. The thing is I have never done such a thing. What do I need and how do I need to setup this master server on my own host.
I have a shared Linux hosting.
Thank you
