Yeah that's true. And, you could just as well have used /bin/false :).
But, a better answer to his question of disabling telnet completely
is just removing the telnet line from /etc/inetd.conf. This will
really make all telnet connections impossible (I prefere the /bin/true
option myself, but he seemed to ask for disabling telnet altogether).
