Hi,
It is not possible to run dpctl without passive listening port.
Please try the following.
1) Modify custom_script.py as follows.
(listenPort: port to listen on for dpctl connections.)
> / s1 = net.addSwitch( 's1' )/
> / s2 = net.addSwitch( 's2' )/
- s1 = net.addSwitch( 's1' )
- s2 = net.addSwitch( 's2' )
+ s1 = net.addSwitch('s1', cls=UserSwitch, listenPort=6634)
+ s2 = net.addSwitch('s2', cls=UserSwitch, listenPort=6635)
2) Execute the following command before running dpctl.
(ofprotocol: secure channel, a relay for OpenFlow messages)
$ ofprotocol tcp:127.0.0.1:6634 tcp:127.0.0.1:6635
thanks
