Alright Sebastian, I've managed to get the virtual box a= nd Ubuntu running on the computer and I went to go see the packages I have = no idea which one to install there's a whole lot of them. Forgive me th= is is all new to me. Which one do I acquire and how to install it?

=C2=A0 =C2=A0 =C2=A0 =C2=A0 I only tested ubuntu 12.04LTS, but certainly I = would try the current 14.07 LTS today.

>=C2=A0 Well... I am new to all this stuff so I'm asking you to plea= se help me on the subject like after everything is up and running on the co= mputer,

=C2=A0 =C2=A0 =C2=A0 =C2=A0 Oh, sure I am happy to help you with getting be= tter data ;)

=C2=A0 =C2=A0 =C2=A0 =C2=A0 First step is getting the vitalized linux up an= d running, then python 2.7 (I assume that python will be part of the distri= bution), with matplotlib; and finally netperf-wrapper. I assume it might ta= ke a bit trying to figure out all the required packets installed, but it sh= ould be reasonably quick to get this up and running=E2=80=A6 Just give it a= try and let me know if/where you get stuck
=C2=A0 =C2=A0 =C2=A0 =C2=A0 It would be most excellent if you could documen= t the whole procedure somehow so we could put it somewhere on the net to ma= ke it easier in the future...

Best Regards
=C2=A0 =C2=A0 =C2=A0 =C2=A0 Sebastian
