Hello again Sebastian,
this is the output that i have gotten when entering the command and
following your directions
ubuntu at ubuntu:~/bufferbloat$ 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
