I am using Ubuntu 14.04 and I am trying to connect to my university network via VPN. I installed Cisco VPN and seems to be working normally. I connect to the network and it says connected, but when I check the IP address of my machine, I see that it is still using the local IP and not the one from the university. If I check the syslog with the following command:
less /var/log/syslog | grep NetworkManager
I get in many places the message
NetworkManager: <warn> /sys/devices/virtual/net/cscotun0: couldn't determine device driver; ignoring...
I suppose the problem is related to that. Is there an easy way to fix this problem?
