Hi,
when examining the field "tcp.analysis.bytes_in_flight" in Wireshark Version
1.2.9 (SVN Rev 33171) it seems Wireshark doesn't always calculate the correct
value.
Attached you'll find a capture file and an excel sheet derived from it to
illustrate many occurrence of the wrong calculation. In the excel sheet I added
the column L == "Should be" with the manual calculated values.
The capture file was analyzed on a Windows XP SP3 with all the latest Microsoft
updates.
Best Regards,
Stefaan
