[pox-dev] Requesting port statistics (problem with connection)

[Tmusic]

Hi,

Thanks!
I'm indeed running python 32bit in a VM.
Betta can run now, but topology discovery is not working.
When running the topology and openflow.topology components, I get following
error:

Traceback (most recent call last):
  File "/home/openflow/pox_workspace/OFcontroller/pox/boot.py", line 447,
in boot
    if _do_launch(argv):
  File "/home/openflow/pox_workspace/OFcontroller/pox/boot.py", line 187,
in _do_launch
    f(**params)
  File
"/home/openflow/pox_workspace/OFcontroller/pox/openflow/topology.py", line
316, in launch
    core.register("openflow_topology", OpenFlowTopology())
  File
"/home/openflow/pox_workspace/OFcontroller/pox/openflow/topology.py", line
66, in __init__
    if not core.listenToDependencies(self, self._wantComponents):
  File "/home/openflow/pox_workspace/OFcontroller/pox/core.py", line 481,
in __getattr__
    raise AttributeError("'%s' not registered" % (name,))
AttributeError: 'listenToDependencies' not registered

Topology seems to be ok, but PyDev indicates an unresolved import in
openflow.topology (xid_generator).

Any ideas?

Thanks,

Tim
