SSH connection problem

[Dustin Breese]

Cool, good job in debugging.

Now, your netstat output shows that the listener is only using ipv6,
so lets try forcing it to ipv4.  No idea if this is the issue or not
-- Does your laptop show the same netcat output?

To force to IPV4 on your desktop:
$ sudo vi /etc/ssh/sshd_config

At the top, uncomment
ListenAddress 0.0.0.0

And then
$ sudo /etc/init.d/ssh restart
