There's nothing wrong with the tcpdump data (I suspect). You're
running up against a tcptrace limit that is confusing me, though. The
program wants to "name" each host pair. The first in a2b, then c2d,
etc... zzy2zzz, etc. Those names are used in the textual output and
as the names of the files that it can create. The length of those
names is supposed to be limited to 8 characters, which my comment in
plotter.c:HostLetter() says should "limit" you to 209Billion hosts per
file. I don't imagine you're facing that limitation, so something
else must be happening.
My first suggestion, if you're up for it, is to do a little debugging
in the HostLetter function (it's short) to show you what is going
wrong. If you're not comfortable doing that, could you please put a
copy of your binary input file someplace that we can get to it and
then send us a pointer. Then I can have one of our students find the
problem. It's very puzzling...
