Your post made me remember what a dinosaur I am. I'd forgotten
that the recent versions of amanda allow several alternative
authorization protocols to be specified on a client by client
basis. Some of these use TCP. So the accuracy of my comment
is dependent on the OP's configuration. For the default, or
for older amanda versions, I believe it was accurate.
