Note that since you have not started any OpenFlow controller, you will get an error message like unable to contact the remote controller at 127.0.0.1:6633. Since the X11 forwarding is also enabled, you can start Wireshark to be able to capture the OpenFlow traffic. You can start Wireshark by entering the following command in your terminal (PuTTY):

mininet@mininet-vm:~$ wireshark &

This will open the Wireshark GUI and you can start capturing the network traffic and filtering the OpenFlow traffic as explained in Chapter 2, Implementing the OpenFlow Switch.

Now you can start your remote OpenFlow controller. This controller is in fact running inside your OpenFlow laboratory VM. So you need to go to your VM console and enter the following commands:

mininet@mininet-vm:~$ cd pox mininet@mininet-vm:~/pox$ ./pox.py forwarding.l2_learning
