Title: Fin directly after SYN/ACK
Hello,
I see the following behaviour on a SUSE Linux 2.6.16.27-0.9-smp kernel. With
the initial SYN having WS=0 the WS=9 in the 2'nd line isn't taken into account.
If so it looks to me that the windowsize of 12 is the reason that the FIN is
directly send. Is this the correct behaviour?
Many thanks in advance
