SSH doesn't require portmap. It uses a fixed well-known port. You
might not have sshd running on the destination machine. You could use
ps ax
to find out. If it's running, and the machines can ping each other, the
next thing to try is
telnet destination ssh
If a server answers, then you're reaching it, so the next place to
look for the answer is in the sshd config file. That's
/etc/ssh/sshd_config. There's some on-system documentation, and a
comprehensive book published by O'Reilly.
