In the unexpected case that the above command just success please try: 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=20 and again send the output=85 And finally if all the above succeeds please try=20 ./netperf-wrapper =97gui and send the output Hope that helps...

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=92t 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. > > > > > > Best Regards > > Sebastian > > > > > > On Oct 19, 2014, at 21:16 , Ernesto Elias = wrote: > > > > > root@cerowrt:~# /usr/lib/CeroWrtScripts/netperfrunner.sh > > > 2014-10-19 15:10:27 Testing netperf.bufferbloat.net (ipv4) with 4 = streams down a = = nd up while pinging gstatic.com.
