Hi Murphy, I am now sure that there is nothing listen on the 6633 port.
I have tried to reinstall pox with git clone http://github.com/noxrepo/pox and then, when I invoke pox.py forwarding.l2_learning the system shows the same errors messages. I test this comamnd line in several host and the problem persist. Please, could you help me? Many thanks in advance. 2013/5/4 Arturo Martín <[email protected]> > Ok, > > Thanks a lot Murphy.
