A couple folks have reported duplicate packet issues associated with
setting a delay.
In at least one report, the tcpdump capture was performed on the nistnet
system. I just attempted to recreate the problem. With:
[machA] <-> <NISTNet> <-> <machB>
I performed a ping from A to B and was running etherial on machA to
capture packets. I used a simple "--delay 1000" for each direction.
I saw no indication of duplication.
I suspect this is a case of the packet capture being incompatible
with the way NISTNet hooks the network on the NISTNet system.
Can either of you reproduce the problem when capturing packets external to
the NISTNet machine? If so, please describe your setup in enough detail
for me to replicate it. In particular, what were the 'cnistnet' commands
used?
