[pox-dev] Using POX controller with openwrt

[Murphy McCauley]

I can't answer the OpenWRT parts, but see inline...

I wouldn't specify the address unless I had a good reason.  Also, 6633 is the default, so you don't need to specify it.  So basically, I wouldn't specifically enter openflow.of_01 and its options in this line.

You shouldn't generally need to run POX with special permissions, so you shouldn't need to sudo.

You aren't running a POX component that actually takes care of forwarding.  Even if everything was working correctly, POX isn't actually setting up flows here so ping won't work.

All together, I'd say a better commandline to start out with would be the first one shown in the POX manual (in the "Quick Start" box in the "Invoking POX" section):
./pox.py samples.pretty_log forwarding.l2_learning

You should be able to at least see if switches are connecting.  If you're still having trouble, turn up the logging and post your logs to the mailing list.  (You can increase the logging detail with ./pox.py samples.pretty_log --DEBUG forwarding.l2_learning).
