This question doesn't really have anything to do with POX, and I'm not an expert with pktgen, so you may have more luck asking for support elsewhere.
A few notes below.

You just need to learn how to use it. This is done by writing commands to one of the special files in /proc, and there are scripts to simplify this. It's partially documented in the Linux kernel documentation for the module, and more fully documented in the paper about pktgen: http://landley.net/kdocs/ols/2005/ols2005v2-pages-19-32.pdf Good luck. -- Murphy > I need help! > > Subject: Re: [pox-dev] "gephi_topo.py" component and "pktgen" missing > From: murphy.mccau...@gmail.com > Date: Mon, 10 Feb 2014 13:29:06 -0800 > CC: pox-dev@lists.noxrepo.org > To: u_r_wel...@hotmail.com > > The gephi_topo component isn't meant to work with a browser.
