Dear Murphy! "pktgen" directory was created after executing "modprobe pktgen" command. However its directory contains only the following two files:/proc/net/pktgen/pgctrl/proc/net/pktgen/kpktgend_X And does not contain any other file like:/proc/net/pktgen/ethX Moreover the output of command "# cat /proc/net/pktgen/kpktgend_0" is:Running: Stopped: Result: NA Now I do not know what commands to execute in order to enable CONFIG_NET_PKTGEN to compile and build pktgen.o either in kernel or as module. I have searched alot on the internet but haven't got an answer. For information, I also executed the following commands:# cd /lib/modules/`uname -r`# find . -name "pktgen.*o" -print And the output was:./kernel/net/core/pktgen.ko I need help!

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. And I can see the misc.gephi_topo component from Carp now. Now I have executed the following command as mentioned on the POX Wiki webpage:./pox.py openflow.discovery misc.gephi_topo host_tracker forwarding.l2_learning But when I try to open "http://127.0.0.1:8282/"; in my browser, only {"dn": {"filter": "ALL"}} is displayed and that too after a long time. And the log displays the following error message:INFO:misc.gephi_topo:Client connect ERROR:lib.ioworker:Socket <GephiWorker> error 104 during recv: Connection reset by peer INFO:misc.gephi_topo:Client disconnect I switched to Dart but no success. I thought I did not have the Gephi plugin for Graph Streaming installed. So I have downloaded its zip file from:https://marketplace.gephi.org/plugin/graph-streaming/ But I don't know how to install this plugin, as I am a new Linux user. Can you please guide? And is this the solution? Regards!

But it does not have the directory named "proto" inside "/home/mininet/pox/pox" directory. But the components mentioned to be inside the "proto" directory on the POX Wiki webpagehttps://openflow.stanford.edu/display/ONL/POX+Wiki are present in the "misc" directory instead. But the problem is that this "misc" directory does not contain the "gephi_topo" component. So can anyone share this component with me? I'd recommend you not complicate your life and just upgrade your POX to carp or dart. You can probably do this with just "git checkout carp" from the POX directory. If your VM has internet connectivity, you should do a "git pull" first to make sure you're getting the latest. Secondly, I want to use "pktgen" which is supposed to be present in the "/proc/net/pktgen/" directory. But there is no "pktgen" directory present in the "/proc/net/" directory. So from where and how can I install "pktgen" in my Miniet 2.1.0 VM? This is part of the Linux kernel, often built as a module. It's probably installed and just not loaded. From a root prompt, do "modprobe pktgen" and see if /proc/net/pktgen appears. -- Murphy
