Intrepid Ibex : Static IP addresses not being saved ( Network manager )

Problem :

On reboot previously saved settings aren't restored, instead it defaults to "auto eth0".

Solution :

Make a new connection with your Static IP Details, and don't make it the "System Settings"

a) Don't touch the default "auto eth0" at all. Just copy your MAC address.

b) Make another connection with all your "Manual" settings.

IMPORTANT : Don't check the "System Settings" box on the new connection. Let "auto eth0" be the one with "System Settings".

What happens on reboot is that ubuntu will first try to make a connection on "auto eth0" and when it fails(provided that you aren't connected to a DHCP server), it moves over and makes connection on your new connection.

c) If this still doesn't work directly edit the "auto etho0" and ad you settings but, UNCHECK the "System setting" box.

And yes, things will have to different if you are connected to a DHCP server but still require Static IPs.

OR -- Remove the Gnome network manager, and then configure the interfaces manually.
