Since you're using a remote controller, but have no pointed out which IP mininet must connect to, the default IP it tries to connect is 127.0.0.1, tcp port 6633. But you didn't show here how you started the controller. My guess is that you didn't. To use the 'internal' mininet OpenFlow controller, do not use the '--controller' switch, although I think this is not the case, since you are trying to sniff the OF message exchange. -- Att Lucas Brasilino MSc Student @ Federal University of Pernambuco (UFPE) / Brazil twitter: @lucas_brasilino
