Could you do a transfer of about 5MB and capture the entire TCP session with tcpdump on the source *and* target machine at the same time? I'll have a look at it to find out why TCP is unable to open the window. tcpdump -n -i bge0 -p -w dump_source "tcp host 1.2.3.4" And then make the two files available somewhere I can download them. -- Andre
