Hi, I'm using pktgen to create DNS query packets for internal testing (I tweaked the source code a bit). It's certainly fast enough, but I'd need some more functionality to build a more comprehensible DNS testing suite. First I'd need a range of IP addresses, for instance the first DNS query would come from 1.1.1.1, the next from 1.1.1.2 etc. As far as I know, port X's IP is assigned only once (for instance set ip src 0 1.1.1.1/24). Is there a clever way to change this? If you consider this a useful feature, I'll submit the code of course.
Best regards, Mark
