It's easier to just change the port it listens on.  'sshd -vvv -p2022'
on the server, and 'ssh -vvv -p2022' on the client.  Alternately,
start a new sshd on a new port, connect to it, and restart the primary
sshd on the default port.  If you're concerned about something weird
happening.

If your firewall blocks stuff, maybe use port 80 (http) or 25 (smtp)
as your alternate, those are usually open.
