Do you have connectivity to controller? What is the result of ping controller?

To me, the error name or service not known indicates that the name controller is not translated to an IP address. One possibility: NetworkManager is running and interfering with your manual network setup.

Why are you installing Pike, by the way? It is almost two years old. The current release is Stein, and Train will be released in two months.
