Request help with Kandoo/Beehive Controller Startup

[Mark Kazunaga]

Greetings.  I appreciate any assistance you can provide.

I am trying to startup the Kandoo/Beehive controller in mininet, but am having problems with the command: 

go run main/main.go -laddr IP:PORT

I have been really struggling over the week in learning how to use go and the command.  I am not sure what to set the GOPATH to.  I am a very novice LINUX user.

I keep getting a "cannot find package error, although my GOROOT is /usr/local/go and GOPATH is set to /home/mininet/go

I guess you have cloned the controller by git not using "go get".

Just run this command:

go get github.com/packet/packet/src/go/packet

You can also remove your beehive-netctrl clone and install it using go:

go get github.com/kandoo/beehive-netctrl

Hope that helps!

It looks like that you are running an openflow controller (maybe another instance of beehive) on the same port (ie, 6634). You should kill that application.

Some other notes:

1. Run "go run main/main.go -help" to see the command line arguments.

2. -laddr is for the beehive listening port not for openflow. For openflow address, use "-of.addr=127.0.0.1:6633".

3. If you are running your a cluster (multiple beehive SDN controllers) on the same machine, please make sure that your listening port addresses for openflow and beehive are not the same.

Soheil, thank you.  I appreciate your help. 

It seems to have worked.  However, now I get this error:

mininet@mininet-vm:~/go/src/github.com/kandoo/beehive-netctrl/kandoo$   go run main/main.go -laddr 127.0.0.1:6634

Do you know how I can resolve this?
