I run SSL on my home machine (Linux 2.0.23) and the machines I administer
(IRIX 5.3). I haven't tried the SSL telnet for Win yet.

Make sure you use the latest version of SSL-MZtelnet if you run IRIX, the
previous versions didn't work too good. Apart from that it works like a
charm.

Dreaming about an SSL POP server... ;)
