Hi Ernesto,
it seems that I forgot to mention that you need to change into the buffer bloat/netperf-wrapper directory first:
so please try:
cd ~/bufferbloat/netperf-wrapper
followed by:
date ; ping -c 10 netperf-eu.bufferbloat.net ; ./netperf-wrapper --ipv4 -L 300 -H netperf-eu.bufferbloat.net rrul -p all_scaled --disable-Log -t netperf-wrapper_test
that hopefully should start netperf-wraper for good and display an image showing downlink bandwidth, uplink bandwidth and latency over time. Please note that this plot shows the average rates of 4 streams (for up and down), so for your total bandwidth you need to multiply the numbers by 4.
Akso note that with “netperf-wrapper —gui” you can select different plot types that can show total bandwidth or box whisker plots (just play with the GUI).
Best Regards
Sebastian

I assume it might take a bit trying to figure out all the required packets installed, but it should be reasonably quick to get this up and running… Just give it a try and let me know if/where you get stuck

Shaping at the rates you are interested in probably will take 100% CPU of the router, so there is no slack for running net server and netperf instances at the same time. Also I would recommend to use netperf-wrapper (https://github.com/tohojo/netperf-wrapper) instead of netperfrunner.sh as it allows so much nicer visualization of the queueing over time. netperfrunner.sh is great tool for quick testing and figuring out link capacities and worst case latency under load increase (LULI), but for more thorough comparisons it ain’t made. Netperf-wrapper will run under linux and macosx natively, but will also run (well enough) in a linux virtual machine on a windows box.
