Just because you're using a crossover cable doesn't rule out firewall
or other such socket level interference.  I'm not saying that's your
problem, but using a crossover cable doesn't rule it out.

I haven't looked to see what changed between 2.5.0 and 2.5.2.  It's
all pretty basic socket stuff.  I wouldn't be surprised if that is
when the additional auth mechanisms (bsdudp, bsdtcp) were added.
However, if no one chimes in, it's not that hard to look yourself.  If
you can narrow it down a bit to where there seems to be a problem in
the code, the amanda-hackers@ list might be able to help more.
