Looks like sshd isn't running to me.

To be sure go to a tell & type: telnet host 22

(where host is your remote host).

If you get:

telnet: Unable to connect to remote host: Connection refused

Then there is nothing bound to the port (or a firewall setup to reject
packets, but this is less likely).

If you get a different response, tell us what it is & we can assist in
diagnosing it from this.

Type:

ps ax | grep ssh

And see if you get a line mentioning sshd.

Ah ok.  Now I'm really interested to hear the results of the
ps ax | grep ssh

Hopefully it won't come to that :)

Do a netstat -a | grep LISTEN and see what, if anything, is listening on
port 22.

Random thoughts: something bound to port 22 ahead of your favourite sshd,
there is a problem with a library & sshd isn't starting properly, config
change broke sshd.

Get back to us with answers to the above questions.  This will help as
diagnose.

Cheers,
