Fair enough. I forget I've been using Unix-type systems since the mid 80s.

I still use inetd - it's a great piece of my toolkit. There have
been improvements and tweaks along the way, but it's a really quick
and convenient way to bring up a daemon written in nothing more than
shell script. Here's a trivial that appears to offer an FTP service but
actually doesn't:

    #!/bin/sh
    #
    echo "421-FTP not available here."
    echo "421 See http://www.example.com/no-ftp-here for alternatives"
    exit 0

If you create that as /usr/local/bin/no-ftp and make it executable,
drop the following line into inetd and send it a SIGHUP ("killall -HUP
inetd") you have a new service operational:

    ftp     stream  tcp     nowait  nobody  /usr/local/bin/no-ftp

Yes. On one's on LAN it's not so much the encryption as the functionality
that wins. And I can use one tool family (ssh) regardless of whether
the target is on my LAN or elsewhere.
