Back in the good ole days before we had systemd I could edit /etc/network/interfaces and have networking restarted by doing a start stop on /etc/init.d/networking. But with systemd this doesn't seem to work. As well as running # /etc/init.d/networking restart I've tried # systemctl restart networking.service # service networking restart And the above commands with an explicit start then stop instead of restart. But any changes made to etc/network/interfaces aren't applied. On the survey the commands above appear to be doing nothing. I'm not using network-manager but resolvconf is installed and is populating /etc/resolv.conf, although only after a reboot. In the systemd world how do you restart networking with new settings with our rebooting? thanks in advance.
