Server 12.04 - Suddenly cannot access SSH on LAN

view story

http://askubuntu.com – I had ssh running on my LAN server. Suddenly (not sure what I did), I cannot access the LAN server via ssh. When I try, it just hangs for a while with no response and finally comes out with a timed out message. ssh: connect to host port 22: Connection timed out As I recall, maybe I got into some trouble trying to install phpmyadmin and pgmyadmin. Still cannot get that going either but this question is for SSH. I just can't reach my own LAN server from my own desktop. Not sure if it matters, but I have TWO network cards and one's meant for Internet connection and the other j (HowTos)
