I just got around to playing with it, and it seems that the problem we
discussed previously depends on the type of interface that tcpdump
listens to.  The program likes Ethernet dumps, but not (kernel) PPP
dumps.  I haven't tried any other interfaces.

townhouse:~$ tcpdump -i ed1 -w ed1.trace
tcpdump: listening on ed1
^C
2 packets received by filter
0 packets dropped by kernel


townhouse:~$ tcptrace ed1.trace 
1 args remaining, starting with 'ed1.trace'
Ostermann's tcptrace -- version 4.0.2 -- Wed Jul 16, 1997

Running file 'ed1.trace'
2 packets seen, 2 TCP packets traced
*** 1 packets were too short to process at some point
        (use -w option to show details)
  1: charon.townhouse.org:1650 - skellar.townhouse.org:23 (a2b)    1>    1<  (reset)


townhouse:~$ tcpdump -i ppp0 -w ppp0.trace
tcpdump: listening on ppp0
^C
30 packets received by filter
0 packets dropped by kernel


townhouse:~$ tcptrace ppp0.trace 
1 args remaining, starting with 'ppp0.trace'
Ostermann's tcptrace -- version 4.0.2 -- Wed Jul 16, 1997

Running file 'ppp0.trace'
Don't understand packet format (9)
