Agreed.  It is the SSH protocol, but it is not the SSH *service*.  It
violates the standard (as you note).

If I write a trojan that uses HTTP to process requests, then park it on
31337, I do not have an HTTP serv(er|ice).  I have a trojan which happens
to use the HTTP protocol.

No, not at all.  There's a big difference between a *standardized service*
and it's underlying protocols.  In order to be SSH, it must comply with
all of the standards for SSH.  Otherwise, you get a M$ Windows product.

I understood that risk during the first post, and deliberately made note
of that.

As a non member of the appropriate standards bodies, what I would like is
irrelevant.  If you assess a site, and report that they have ssh running
on port 31337, you are not providing factual data - you are providing an
uninformed opinon, which is *wrong*.

Except for you, I think everyone else *got* the point.

Then I'm being difficult.  But in the end, this is my attempt to realign
your thinking on it.  That you are immobile is not something I can help.
