[pox-dev] Bind POX to Multiple IP Interfaces

[Murphy McCauley]

I think this MIGHT be as easy as making the launcher for of_01 multi-instance aware.  I don't have time to actually check, but here's a hacked version which at least doesn't crash immediately. :)  Maybe you can give it a shot?

def launch (port=6633, address="0.0.0.0", name=None, __INSTANCE__=None):
  if name is None:
    basename = "of_01"
    counter = 1
    name = basename
    while core.hasComponent(name):
      counter += 1
      name = "%s-%s" % (basename, counter)

  if core.hasComponent(name):
    log.warn("of_01 '%s' already started", name)
    return None

  global deferredSender
  if not deferredSender:
    deferredSender = DeferredSender()

  if of._logger is None:
    of._logger = core.getLogger('libopenflow_01')

  l = OpenFlow_01_Task(port = int(port), address = address)
  core.register(name, l)
  return l
