Hi,
How to use OpenFlow controller in a normal python script? I see that the example in https://ryu.readthedocs.io/en/latest/writing_ryu_app.html#whetting-your-appetite can run successfully using command “/usr/bin/ryu run ~/l2.py”. I want to run the l2.py script with “python3 ~/l2.py” (by adding “if __name__ == "__main__":” and with some more coding. I tried to do something but did not work. I kept the “L2Switch” class from the example and in my main added “l2 = L2Switch()” and “l2.start()” but that does not work. I observed that the ports 6633 and 6653 are not open indicating that the OpenFlow controller has not started. With best regards, Govinda
