I assume the quickest way to find out if the remote host supports ssh
is to just try a connection on the ssh port on that machine.

I just tried to connect to port 22 on my desktop machine (which is
not reachable because it's behind a firewall).  I used
open-network-stream.  It's been waiting for a couple of minutes
already, and no timeout in sight.¹

Presumably, ssh would be the first thing to try (over telnet and ftp).

I stand by my previous opinion: do not try to auto-detect whether ssh
or telnet or Kerberos login or SSL-Telnet or ftp or whatnot should be
used.  Let the user specify this.

But do try to autodetect the other parameters, once the network
application has been set.  For example, autodetect whether base64
encoding or uuencoding should be used.  Possibly it's also possible
to figure out whether and out-of-band method should be used.


¹ Is this experiment unfair due to our specific firewall
  configuration?  I'm not a networking expert.
