You could try 'nmap localhost' on that machine to ensure that ssh is running on that port.
Could it also be a protocol version problem? Like, the client is using protocol 1, but the sshd is only allowing protocol 2 connections?
You could also try an rpm -qa --last and see if there might have been an update near the time that it stopped working.
