I'm not entirely sure how OpenSSH decides which protocol version to
use.  It's entirely possible that there's a hand-shaking phase in the
connection process, during which the client and the server figure out
which versions of the protocol they support, and in what order.

So, it would seem that my earlier statement about it defaulting to
version 1 may not be correct.  Mea culpa.  (Most of the machines that I
deal with are running potato, which until recently was restricted to
protocol v1.  The one woody machine I run only talks to a potato
machine, so the fact that it supports protocol v2 was, until I installed
the security fixes, irrelevant.)
