Lee <danieltim...@gmail.com> Nice feature, this look very usable for testing. I think my QA asked me for something similar. One nitpick is that script named pktgen_sample03_burst_single_flow.sh implies this is a single flow, but by specifying a port-range this will be more flows. I'm okay with adding this, as the end-user specifying a port-range should realize this. Thus, you get my ACK. Acked-by: Jesper Dangaard Brouer <bro...@redhat.com> Another thing you should realize (but you/we cannot do anything about) is that when the scripts use burst or clone, then the port (UDPDST_RND) will be the same for all packets in the same burst. I don't know if it matters for your use-case. -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
