You'd have to use the clients in krb5-appl-clients and the telnetd in
krb5-appl-servers.  The 'telnet' in krb5-appl-clients has an -x flag
that encrypts the data stream.

I never use any of this anymore.  In fact, the only reason why I used
kerberized telnet was back before OpenSSH was as widespread, and
encrypted telnet was less overhead on the really old Suns I used.  I
just wanted to point out that the 'telnet' protocol is more than plain
text.
