Still don't know why you'd use these instead of ssh/sftp, though.

As noted here earlier, if you update OpenSSL you stand a good chance
of dropping ALL your ssh conections until you install a matching
ssh update.  Most sshd will not start if the openssl libs on the
disk are not the same exact version it was compiled with.

When I am updateing hosts hundreds or thousands of miles away in
an unattended facility I can not take chances on a fatal mistake
during an update.  A backdoor telnet has saved my butt many times.

Also seen cases where a trojaned sshd was installed on the target
machine, but it would not run due to configuration issues.  Having
a backdoor telnet means the system is back up in 5 minutes of
remote twiddling instead of dispatching someone to a remote co-lo.

Gotta keep the single points of failure to a minimum.
