Hello All,
Two devices tries to communicate.
1st device tries to initiate TCP connection. But instead SYN packet with
conventional window size = 65535 or MSS,
it sends packet with window size = 0.
2nd device replies not.
I have reread RFCs and not found direct answer.
Does ISN (initial sequence number) is data or not and should be
applicable window size for it?
Wireshark, for example, does not display information about window size
in first SYN packet.
The question is who is guilty 1st or 2nd? :)
Oleg
