I'm having issues with a machine that stopped replicating with mysql. It's managed by a guy on another continent but recently I've had to get involved.

The server is running Ubuntu server 9.10

I can't log in with SSH, there is no response. On the server itself I can ssh to localhost fine.

I thought maybe it's the firewall rules. I'm no expert on IP Tables, but I believe that's not the issue as I removed all the rules. But it still won't let me in.

Any ideas? it's acting from other machines as though the service isn't listening, but I know that it is. It's like this for all services.
