It would help a lot if we knew a bit more about the setup. Are *all* the
xx.xx.xx.xxs the same? Are they both on the same wired network? Have you
checked the firewall on whichever one is to be a server to check that it
allows SSH through? If you haven’t chosen a firewall, you might want to
either:

 * temporarily run
   service iptables stop
   to see if the firewall is causing problems

 * run system-config-firewall, and ensure that SSH is marked as trusted

 * or run
   service iptables status | egrep ":22 "
   and check that there is an output line. If not, you haven't enabled
   SSH through the firewall.

If none of that helps, then I suspect your computers are on different
networks. Can they both access the Internet correctly? What sort of
devices do they use to access the Internet?

Hope this helps,

James.
