I understand all that.

You'd think. And as I said, this has been working for years, on three or
four OEM's hardware. Suddenly, there's this new box from Penguin that's
IBM-based, and it's using something called "openether.org" firmware, and
it takes minutes between timeouts, instead of seconds. I'm talking to the
OEM, but trying to figure out what's going on. I haven't found a timeout
on the server side, though I suspect there is one, but I really *don't*
want to make it 20 min. I've also just been googling, trying to find out
if -mapfile for tftp will let me rename what it's looking for to
"default", but that search is going nowhere, fast.

I'm under the impression I know - the client *tells* me what it's looking
for, in the order above, but it sits there, and sits there, before it
tries the next option.
