what happens is that when sats advertises 0 sized window (frame
#1704) and viluvere still sends a single byte to it (rfc793 allows
to do this) (frame #1705) then sats increases his window to 65536
(frame #1706). i think that there is bug in tcp_receive_window
function (tcp.h). when rcv_wup is < rcv_nxt the answer should be 0
not -1.
This is fixed in my sources which will be merged to Linus shortly.
Later,
