Hi Ernesto,
so I would recommend to first install git from a terminal in your ubuntu
virtual machine:
sudo apt-get install git
then create a directory where to store horse netperf-wrapper:
mkdir -p ~/bufferbloat ; cd ~/bufferbloat
then clone the netperf-wrapper repository:
git clone git@https://github.com/tohojo/netperf-wrapper
now you can test what is missing by calling:
./netperf-wrapper
this will most likely complain about missing components, please send the output
of this command so we can take it from there.
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
and again send the output…
And finally if all the above succeeds please try
./netperf-wrapper —gui
and send the output
Hope that helps...
Best Regards
Sebastian
