One of the main strong point on Linux, is that we are not forced to use a graphic interface to perform operations.
That can be view as a draw back but to perform operations faster and remotely, that's really useful.
Here are a few commands to manage network intefaces on Ubuntu :
- To print configuration
- To start or shutdown a specifcnetwork interface (e.g. eth0 )
$ sudo ifup eth0 $ sudo ifdown eth0
- To get a dhcp address
$ sudo dhclient
- To restart all network interfaces
$ sudo /etc/init.d/networking restart
These commands used to work ... but do not seem to work anymore with v. 14.04 ! ? !
