Networking misconfiguration

Asked by Jon Charge

I attempted to reconfigure my network, however, I've royally messed it up. I have internet connectivity, but I've also have a few mis-configurations I think. I was attempting to reconfigure my network to permit

DSL MODEM -> DESKTOP -> LAPTOP

But I don' need that anymore, and have undone what I could.

I staill have symptoms like, when attempting to restart my network...

--START PASTE--

jon@cloud:~$ sudo /etc/init.d/networking restart
[sudo] password for jon:
 * Reconfiguring network interfaces... Ignoring unknown interface eth0=eth0.
                                                                         [ OK ]

--END PASTE--

Ignoring unknown interface?

And here is my interfaces file...

--START PASTE-- /etc/network/interfaces

auto lo
iface lo inet loopback

--END PASTE--

What I would like to know...

1) How do I debug this

2) Is there a way to just reset the entire network settings to when it came "out of the box" reset to defaults?

Thank you for your help,

Jon

Do you use a desktop or server install? The desktop has a gui app called nm-aplet which can help If you use the server we wil need to be sneakier

Then network manager will help you set the addresses, or you can use the file:

/etc/network/interfaces
