Telnet is disabled by default on all Red Hat linuxes since 7.1 because
it's a HUGE FRIGGIN' security hole.  Never, EVER use telnet.  Use
ssh instead.  With telnet, EVERYTHING goes over the net in cleartext
(including passwords).  ssh encrypts everything using a (default)
blowfish encryption algorithm.

If you must use telnet (very, very bad idea), edit /etc/xinetd.d/telnet
and change the "disable = yes" to "disable = no", then restart xinetd
by:

	/etc/rc.d/init.d/xinetd restart

or

	service xinetd restart
