Because you're either (a) not running the 'ssh' command with enough
verbosity to get the full error text, OR (b) your choice of tool simply
does not have the capability to print that verbosity.

The message you posted a few mails ago - "DH Key exchange failed" - is
nearly always because the two sides cannot agree on a key modulo.

And yet you've still provided no proof one way or the other.  We really
are trying to help you get to the bottom of this (or, well, at least I
was) -- but you're not exactly helping me help you.

Given that port 22 is the standard port for SSH, I would be VERY
surprised that an ISP would get in the way of it.  I mean, sure, they
might've goofed - but if they were blocking it, you WOULD NOT be getting
far enough to have a diffie-hellman key exchange failure.  That's one of
the last parts of the handshake between an ssh server and ssh client ...

Well, since it seems you don't actually want help getting to the bottom
of the issue, good luck to you then.
