The chkconfig utility that ships with Red Hat can be used to manage 
xinetd services, too:

  # list what chkconfig can manage
  /sbin/chkconfig --list

  # tweak /etc/xinetd.d/telnet to turn on telnet server and HUP xinetd 
  # to activate it
  /sbin/chkconfig telnet on

  # check syslog to make sure we got what we wanted
  tail -n 40 /var/log/messages

At that point, you can edit /etc/xinetd.d/telnet to add, say, 
host-based exclusions using "only_from" or "no_access" directives. The 
xinetd.conf(5) man page is helpful in that regard.
