Mike it looks like one of you systems is on the wireless and the other on
the Wired.

Can you run on both servers:
# apt-get install nmap
Then on each server:
# nmap -PN 192.168.0.3
# nmap -PN 192.168.0.4

and post that?

Okay that's possibly a path issue.

if you are in the directory you would enter:

# sudo ./ssh start

otherwise

# sudo /etc/init.d/ssh start
