Hm, since that's an error from libpcap, there really isn't much that
we can do about it - the question is, what causes libpcap to create
that error? You didn't say what platform you were on, which might
help debugging... It sounds like the machine that you ran tcpdump on
has an incompatible libpcap from the machine that you ran tcptrace on;
is this possible?
