I am not very clear with what is active on my system.
On Red Hat based systems I used to do service networking restart and
hence I did the same here also.

How do I determine which one is in use.

After your message I did

 /etc/init.d/network-interface restart

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service network-interface restart

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the restart(8) utility, e.g. restart
network-interface
start: Unknown parameter: INTERFACE


and then I also tried


service network-interface restart
restart: Unknown parameter: INTERFACE

then following command seems to disconnect
service network-manager restart
and this is found to work.
But service networking restart does not work.
What is the difference between two and is there an
elegant way for this situation to find out what was active rather than
restarting network-*
