The gephi_topo component isn't meant to work with a browser. It's meant to work with the Gephi graph visualization package (http://www.gephi.org).
So if you want to use it, the first thing you need to do is install Gephi. I think it comes with the graph streaming plugin, if not you can install it through its plugin manager. There's a screenshot on noxrepo.org that shows how to configure the plugin to work with POX. -- Murphy On Feb 10, 2014, at 1:02 AM, Rizwan Jamil <u_r_wel...@hotmail.com> wrote: > Dear Murphy! > > "pktgen" is loaded successfully.
