Hi.
I've posted a tcpdump output ("tcpdump -i de0 -w
scp_local_to_remote.pcap") to the URL below.
http://homepage2.nifty.com/dumb_show/unix/work/scp_local_to_remote.pcap
In this output I ran "scp /boot/kernel/kernel remote_host:"
on the system, and interruped it after 5 minutes
(local_host = "scorpio", remote_host = "pisces").
