Hi Sake,

 

Here you go: http://denuitlaat.be/tcp/windowscaled1.pcap .
It shows that a session is started with a SYN and the option ws is present (ws = 2). The segments following do not show a scaled window size.

 

Regards,

jo

Hi Jo,

 

The window size should consistently be displayed within one TCP session. Between sessions, there could be difference, because either there is no scaling, or the SYN, SYN/ACK were not present in the tracefile. If that does not explain the differences you see, could you provide a small capture showing this issue?

 

Cheers,

Sake

Hi,

 

Is there a reason why sometimes in a connection which received a window scaler (syn;syn,ack) , the window size is

shown as “number (scaled)” and sometimes just as “number” (non scaled) in the next segments. Cause in the last case its not

possible to know the exact window size as the window scale factor is non present in the segments after the syn; syn,ack.

Kind regards,

Jo
