[pox-dev] POX error into Ubuntu 12.10

[Murphy McCauley]

It appears that something else is listening on the same port as POX (6633).  You can use lsof to find it.  Or just check the process list for likely candidates (other OpenFlow controllers or other instances of POX).

Or you could just switch which port POX listens to from 6633 to something else...
