hi,
I am trying to establish SSL connection between OVS and OVS-Controller(
which as per the information on web, is possible). I am using *mininet* for
this.
I am able to generate keys and certificate for both controller and switch.
I am also able to do - ovs-vsctl set-ssl...command..
After this I started the OVS-controller using
sudo ovs-controller -v pssl:6633 -p /etc/openvswitch/ctl-privkey.pem -c
/etc/openvswitch/ctl-cert.pem -C
/var/lib/openvswitch/pki/switchca/cacert.pem
After the controller was started successfully, i tried to create a linear
topology in a python file -
def emptyNet():
net = Mininet( controller=OVSController )
net.addController( 'c0' )
h1 = net.addHost( 'h1' )
h2 = net.addHost( 'h2' )
s1 = net.addSwitch( 's1' )
net.addLink( h1, s1 )
net.addLink( h2, s1 )
net.start()
s1.cmd('ovs-vsctl set-controller s1 ssl:127.0.0.1:6633')
CLI( net )
net.stop()
if __name__ == '__main__':
setLogLevel( 'info' )
emptyNet()
But i get error while creating this.
*It prompts : close the controller already running on port 6633.*
I even tried changing port but no success. Also i tried changing the
controller=remoteController, but this also has not helped.
*I checked in openflow/config.h, and enabled HAVE_SSL flag. But no change
in o/p.*
Can you please help.
Thanks
Ruchika
