Kandoo - Beehive - Controller Error

[mg]

Hi folks,

Just wondered if I could get a little help. I'm doing some work on Distributed SDN Controllers for my dissertation and I'm having a little trouble getting Kandoo working with Mininet.

I have successfully installed Kandoo and appear to be able to run multiple kandoo controllers without issue. I have used the following commands:

Controller 1: go run main.go -addr 192.168.56.101:6644 -of.addr 192.168.56.101:6633 -v 1

Controller 2: go run main.go -addr 192.168.56.102:6655 -paddr 192.168.56.101:6644 -of.addr 192.168.56.102:6633 -v 1

Which produces the following output within Kandoo Controller 2:

The issue I have is when I try to connect Mininet to one of the controllers. I have used the following command:

sudo mn --controller remote,ip=192.168.56.102,port=6633 --topo linear,5

Which produces the following error messages within Kandoo Controller 2:

Subsequently a pingall fails within Mininet - I've tried manually setting the OpenFlow version 1.0 and 1.2 when loading Mininet but still no joy.

Is anyone able to advise what the issue could be?

Thanks for your time,

You'll need to use different state path -statepath as well.
