[ns] emulate network (hope to get an answer)

[Rami .Z.]

i want to build a scenrio when the user have problem connecting to the 
internet
due to miss configured dns or network problem .

my real network  topology is

A---->B----->C

i already manage to capture icmp packets sent from A to B and inject them to 
the simulated network.
bu i wonder if it is possible to avoide the simulated network? i mean to 
generate ns2 trace file
completely based on whatever C capture
for example :
C caputre sent packets
C capture recv packets
so on the trace fill i will this result without any simulated network ?

the reason is that i want to avoid any protocol depandency.


please, can anyone guid me somewhere?

Thnx
