# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
iface lo inet loopback
# The primary network interface
iface eth0 inet static
root@Dev-srv:~# /etc/init.d/networking restart
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service networking restart
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop networking ; start networking. The restart(8) utility is also available.
