Don't allow incoming telnet

[Rory Campbell-Lange <rory@campbell-lange.net>]

Hi.
How do I stop telnet sessions coming IN?
(I only want users to use ssh)

grep telnet /etc/services shows:
    telnet          23/tcp
    rtelnet         107/tcp    # Remote Telnet
    rtelnet         107/udp
    
 telnet /etc/services shows:
    telnet         stream  tcp     nowait  \
    telnetd.telnetd /usr/sbin/tcpd  /usr/sbin/in.telnetd
    
Presumably I can just uncomment the /etc/services entry?

Thanks for any help
Rory
