I've got a capture file that has missing segments for some of the TCP
I ran "tcptrace -l -e <dumpfile> > <summary>" to extract the payload of
the TCP sessions.
In generating the TCP stream extracts, tcptrace filled in the
missing data with NULLs. This is a reasonable implemention choice, but it
would be nice if tcptrace emitted a warning in this case.
(Before analyzing the data, I didn't know that the tcpdump was incomplete.
So, when I looked at the extract file, I thought the application was
sending corrupt data. It was only after looking at the long summary that I
realized tcpdump must have missed some segments. Having a warning about
the missing segments would have avoided the confusion.)
