Then, move it to another port!

1) login and su to root.
2) edit /etc/services.
3) Comment out the line with 'telnet    23/tcp' with the # character.
4) (optional) place a comment at the end of that line as to where you've 
moved telnet to.
5) scroll down the list in /etc/services and find a nice 'fit' for telnet. 
Insert telnet at a new port.
6) Restart inetd: '/etc/rc.d/init.d/inetd restart'

Everyone is scanning for telnet on port 23. It is only a broad port scan 
that will detect telnet on another port.
