How to restart network in ubuntu server 14.04.04？

ubuntu networking network-interface ifconfig

Solution 1

Ifdown ethx ; ifup ethx

Should do it

"service networking restart" isnt working in ubuntu, because other services are dependent on it, theres a more complete answer here https://askubuntu.com/questions/561046/why-is-service-networking-restart-not-working-in-14-04

You are probably using Network-Manager so that would use:

sudo service network-manager restart

When in doubt try:

sudo ifdown <interface>
sudo ifup <interface>

That should work, if doing this over ssh combine the commands:

sudo ifdown <interface> && sudo ifup <interface>

Give that a try.

Looks like this issue is related to the following:
