Hi All:
I'm seeing a strange issue on one of my Ubuntu systems. The python environment
is 2.7.3, after I installed ryu, I get an error stating port 8080 is already
being used.
ryu-manager
loading app ryu.controller.ofp_handler
instantiating app ryu.controller.ofp_handler of OFPHandler
hub: uncaught exception: Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/ryu/lib/hub.py", line 48, in
_launch
func(*args, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/ryu/controller/controller.py",
line 65, in __call__
self.server_loop()
File "/usr/local/lib/python2.7/dist-packages/ryu/controller/controller.py",
line 88, in server_loop
datapath_connection_factory)
File "/usr/local/lib/python2.7/dist-packages/ryu/lib/hub.py", line 85, in
__init__
self.server = eventlet.listen(listen_info)
File "/usr/lib/python2.7/dist-packages/eventlet/convenience.py", line 38, in
listen
sock.bind(addr)
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
error: [Errno 98] Address already in use
However, I have no process' runnining listening to port 8080
lsof -i :8080 <- Returns blank
However, ryu-manager runs fine on my redhat machine, which is also running
python 2.7.3
ryu-manager
loading app ryu.controller.ofp_handler
instantiating app ryu.controller.ofp_handler of OFPHandler
Does anyone have any ideas about this?
Much Thanks
Morgan Yang
