[Ryu-devel] Error[98] address already in use.

[Kiran K. <rok...@gm...>]

Hi team,
I'm using the vm version "sdnhub-ryu-starter-kit.ova" (
http://yuba.stanford.edu/~srini/downloads/sdnhub-ryu-starter-kit.ova).

While running the commands

cd /home/ubuntu/ryu && ./bin/ryu-manager --verbose ryu/app/simple_switch_13.py

I got the following error.

hub: uncaught exception: Traceback (most recent call last):

error: [Errno 98] Address already in use

Please suggest me what might have been the problem.

Thanks & Regards
