I see.  SSH doesn't solve all problems, and therefore must be
worthless.

Now let's look at kerberized telnet.  Someone logs in via
kerberized telnet over an insecure network, then decides to
change his/her password.  Oops.

Someone could screw up OTP SSH+KRB5 logins over IPSec if using a
compromised box with a keylogger installed.  Does that mean each
of these technologies is worthless?

Definitely.  Alas, I'm seeing more "it won't happen to me" than
in the past.  It's almost as if the "logic" is "I hear more about
this, but haven't noticed anything awful, and therefore must be
invincible."
