i believe that -z sll isn't supposed to work with telnetd-ssl (the daemon
package pulled in by ssltelnet). -z ssl is intended for when you talk to a
server that begins speaking ssl right away, for example an https server.
The telnetd, on the other hand, accepts connections as any normal telnetd
in order to maintain compatibility; it negotiates the ssl connection
later. So if your telnet program goes in speaking ssl, telnetd can't
understand it.

The fix: use -z secure on the telnet client instead of -z ssl if you want
to force a secure connection. Or, use -z ssl on the server as well as the
client (and note that non-ssl telnet clients won't be able to connect to
your telnetd).
