Actually, I think the whole thing started on the mgetty list two years
ago.  Then it turned into a discussion between Marc and me, and since
I didn't had any idea how to solve this, Marc did his "rlogin" trick,
and fell silent.  A couple of weeks ago, it resurfaced, and Marc decided
to actually *warn* people about it...

To my knowledge, noboy had been aware of this exploit, or was even
actively using it.  It needs some evil thinking to figure out *all*
the nasties of this issue...
