Starting PPPoE on boot in Ubuntu 9.04 Jaunty

I spend three hours trying to make sure that PPPoE started at boot time on my mothers computer. PPPoE works normally after running pppoeconf or pon dsl-provider, but for some reason would not reactivate on the next boot.

Turns out, I had to change:
iface eth0 inet manual
to
iface eth0 inet dhcp

in /etc/network/interfaces

After the change, PPPoE now starts automatically on boot.

If you need a hand:

• hit ALT+F2.


• Enter the following command:


• gksudo gedit /etc/network/interfaces


• Find the line that read iface eth0 inet manual.


• Change the word manual to dhcp


• Save the file and reboot!
