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
