Is the ypbind service running on the client machine (and of course
ypserv on the server)?
Also, NIS requires portmap, and the ports used by portmap and nis should
of course be opened in your firewall.
I think it is a portmapper or firewall issue; if the server is not running
or unreachable, the usual error is "YPBINDPROC_DOMAIN: Domain not bound"

First: do you really want telnet? By default, Fedora install ssh which
can do everything telnet can, but more secure (telnet transmits username
and password unencrypted over the network).
But if you really need telnet, install the package 'telnet-server' that
is available in Fedora (install from cd, or 'up2date telnet-server), and
enable the telnet service ('chkconfig telnet on').
Next, open the telnet port (23/tcp) in your firewall, probably only for
trusted hosts on your local network.
