Hi Yi
Thanks for your update. I have also noticed that I have to declare remote
controller to ryu using mininet topology. But, previously, six months back, I
did not face this type of problem. Ryu was working perfectly without this type
of declaration.
to start mininet topology, I use the following,
sudo python filename.py
1. do you know how I can get rid of this problem?
2. if I want to use multiple controller in the same mininet topology, how I
have to declare?
Thanks,
-Tanvir

Hi
The default controller is enabled, it will use port 665(3)3, and you can't
start Ryu controller.
To disable it, just set the remote controller.
May I ask how you start your mininet topology?

Sorry for late reply,

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):

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?
