When i execute "sudo mn --test pingall" in above you can see that one
controller is listening, but when you run "netstat -nl | grep 6633", it dosent
show the contoller.
So which controller process to kill ??
And can i have the command to kill these process??
Thank you,

sudo apt-get install telnet
Then:
netstat -nl | grep 6633
If 6633 is in the list, then kill the controller you have running.

There was a bug with a missing telnet package in that ubuntu version IIRC,
which printed a misleading error message. Also did you check using nest at
that no controller was actually running?

Hi,
I just setup Mininet 2.0.0d4 for ubuntu 12.10 and facing weird behaviour
Executing "sudo mn --test pingall" results an "Exception: Please shut down the
controller which is running on port 6633:"
Any fix for this ??
Thank you
