reload /etc/network/interfaces with out rebooting - luv-main

2 Apr 2018

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.
