I believe there is a dumper->taper connection, for direct-to-tape
dumps.  That's how I read docs/PORT.USAGE, anyway -- see the bits
on stream_server() and stream_client().  But both of those
processes run on the same host, so it's still hard to see how a
firewall could get between them.

Unless Amanda's running on the firewall machine itself -- which
I'd consider an unsafe idea anyway!

It looks as though the ones that succeeded all dumped via holding
disk, so in those cases there was indeed no need for dumpers and
taper to talk directly.

Yeah, that was the part that got my attention too!  But then,
it's 2.4.2, so maybe that bug's been fixed.

be the landing area where the crew was, and the Earth, all in the view
of my window. I couldn't help but think that there in front of me was
all of humanity, except me.
