Hmmm. dncopy fails progressively - the first few 32K chunks transfer
correctly, albeit slowly, and then the transfer hangs. The receiving
computer is a uVaxII with a fairly slow disk, so it probably can't keep up
with the incoming data rate - this does indeed point to a flow control
problem. I'll try to get get the 2.4.2 kernel patch and see what happens.

Nothing in /var/log/messages.
