Steam is a content provider for games. The linux version is to set up game servers. (http://www.steampowered.com)

When I use the software (Steam) to install a game server (cstrike). It is shown by the output of Steam...

I am not behind a router for this server and my other linux box.

Also, instead of "Connection Reset by Peer", I can also get "Connection Reset" (without "by peer") or it can just hang.

BTW, I tried to reinstall knoppix on 3 different computers total: the original one, the other linux box, and my own PC (i used the same HD every time). And unfortunately, it NEVER worked.
