Hi,

If you are using the FULL version of the software, two modules are useful:

-RASM (ACE Analyst Real Application Simulation Module).

-SITL (System In The Loop) for injecting real traffic into the simulation

Both are sufficient to import tcpdump files into your simulation.

I'm not sure about the academic version - maybe these modules are not available for academic scenarios.

Kind regards,

Matthias

Thank you Mattias for your reply, but how i can get tcpdump file before import him into OPNET ?

To get a TCP dump file run the command as follows

$ tcpdump -i -s 65535 -w

You will have to specify the correct interface and the name of a file to save into. In addition, you will have to terminate the capture with ^C when you believe you have captured enough packets.
