alright... sorry to bother you with more questions. Hopefully this one
won't be a problem.
I have an assignment in which I have to change the randomizing of the ip
address in the pcap file
For instance, if packet x goes from ip_a to ip_b, and the ip is randomized
to ip_c to ip_d, then all
instances of ip_a to ip_b should be changed to ip_c to ip_d. I'm not asking
how to implement this,
I just want to know where exactly in the source code are the ip addresses
being randomized (would
be nice to know the file, and line number). I just don't want to go messing
with random code and end
up breaking something. I guess I just want to know where I should edit in
the code to add this functionality.
Thanks a lot,
Dileep
