Yep.  Try SSH.  Besides being nine quintillion times more secure, it's
generally included by default on Fedora systems.

My first guess for your NFS issue would be the firewall.  Check
`system-config-firewall` if it's a graphical system or
`system-config-firewall-tui` on the console and make sure the ports
are open, unless you already configured it manually with iptables.

If SSH isn't working, it probably isn't open in the firewall either,
_even if it says it is_ thanks to a longstanding annoying bug.  Try
disabling it and reenabling it in the firewall config to get it to
work.
