Hi Fujimoto
unfortunately, it is working in my laptop. I think the problem is in OS.
Because I am using ubuntu 16.04. Let me see to downgrade it.
Thanks

Hi, Tanvir
It seems to that there is another process using port 6653 or 6633. Please run:
netstat -nltp | grep 6633
netstat -nltp | grep 6653
to see what process is using the port.
Thanks,
Fujimoto

Hi All
Whenever I run Ryu, I get the following error message,
hub: uncaught exception: Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/ryu/lib/hub.py", line 54, in

return getattr(self._sock,name)(*args)

I know that it looks like a common. Now to get rid of that problem, I used the
following command,
tanvir@tanvir-Latitude-E7450:~/ryu/ryu/app$ ps -ef | grep ryu
tanvir 5804 2851 0 16:48 pts/10 00:00:00 grep --color=auto ryu
tanvir@tanvir-Latitude-E7450:~/ryu/ryu/app$
But, still I am getting the same error message. Could you please help me to get
rid of this problem??
