I've got a program called tcpdump, written by Van Jacobsen at Lawrence
Berkeley Laboratory, (mailadds supposedly van@lbl-csam.arpa or 
van@lbl-rtsg.arpa), that was distributed as compiled code for Sun-3 
workstations.  It's a really useful tcp packet-listener and dumper.

However:  I need a Sun-4 version pretty badly.  Does anyone know if
Van's still out there, how to reach those addresses from uunet,
if there's a Sun-4 version of tcpdump, if there's a tool like tcpdump
for the Sun-4, or any of that?

What I'm really trying to do is track down some problems using tcp on
a PC connected to the Sun-3, but apparently Sun's NIT won't track 
packets destined for the host upon which the program is running,
so I can only see half the story, as there's only one Sun-3 on this
net.  However, there's a Sun-4, so if I could run tcpdump on the
Sun-4, I could see traffic between Sun-3 and PC with no problem...

If anyone's got any better ideas than tracking down Van and tcpdump0,
I'm willing to listen, of course.

Oh, also, we're a SunOS licensee, so if anyone has diffs for tcpdump
(I understand it's derived from Sun's own etherfind), I could possibly
apply them to the source we have and generate my own tcpdump.

Any help much appreciated!
