[nznog] Andy Linton is now an OpenFlow expert

It took 2h. About 30m to make an OpenFlow controller PC out of bunch of trash, and boot my controller DVD. "ed" wasn't available on my controlled DVD so I made Andy use nano to configure it. That slowed us down quite a bit. 90m to put OpenFlow firmware on a 3780 switch, including walking up and down the hill to VUW get 1G SFPs. So if you have any questions about whether OpenFlow/SDN works/forwards packets in hardware - ask Andy. He knows. And has a live CD controller.
