You're welcome to have a look, here's the tcpdump of both sides- I was able
to transfer 325000 bytes of a 2mb file with FSP (I've gotten higher with
various settings)
http://webtrotter.com/10_0_0_1.txt and http://webtrotter.com/10_0_0_2.txt
Note, I didn't do a raw dump with the data contained, just -vv, but the
files are still ~200kb.
I didn't see anything out of the ordinary- it just stalls. Again this is
with FSP set up with an infinite timeout. I didn't ping during the transfer
so it wouldn't confuse the dumps, but I can ping before, after and during as
stated previously.
