   # /sbin/chkconfig {service} {on|off}

Run /sbin/chkconfig --list to get the overall list. This covers both
/etc/rc.d scripts (configurable per run level) and xinetd. The config
files themselves are in /etc/xinetd.d/, but enable/disable is easier
using chkconfig.

The actual login is done by login, not telnetd. See the man page
for login(1). It explains that root login is only allowed on a
tty listed in /etc/securetty. You could open that up by adding
pts/0, etc., but it's probably not a good idea to do so.
