| H A D | pkt-gen.c | diff 281746 Sun Apr 19 15:10:21 MDT 2015 adrian Update pkt-gen to optionally use randomised source/destination IPv4 addresses/ports. When doing traffic testing of actual code that /does/ things to the packet (rather than say, 'bridge.c'), it's typically a good idea to use a variety of cache-busting and flow-tracking-busting packet spreads. The pkt-gen method of testing an IP range was to walk it linearly - which is fine, but not useful enough. This can be used to completely randomize the source/destination addresses (eg to test out flow-tracking-busting) and to keep the destination fixed whilst randomising the source (eg to test out what a DDoS may look like.)
