ssh request times out.
I can connect via ssh to my workstation locally, just not from other
machines *i.e. ssh <workstation> works when run on <workstation> but not
when run on a different computer).
Debugging output isn't any help. It shows the connection being attempted
then eventually timing out.
Assuming their names are workstation and server, give us the
output of the following. Use ctrl-c to cancel things as
necessary.

I can get to the server from workstation using ssh. I just can't do it
in the other direction. On server, I can ping workstation but:
$ telnet workstation 22
Trying 192.168.1.20...
telnet: Unable to connect to remote host: Connection timed out
Whereas the other way, I get a protocol mismatch error.
