Open DNS, wireless 11.10ubuntu

Asked by Mark on 2007-10-29

Hi. Am trying to set up Open DNS as per the instructions at:- https://www.opendns.com/start?device=ubuntu
but all I get after following the instructions is:-

ifdown: interface eth0 not configured
Ignoring unknown interface eth0=eth0.

Has anyone else had a similar problem?

Its reporting so cause your Network Device is not referred to as eth0. Might be something else (Wireless ones sometimes have different names)

Doing that command is not so necessary, you can even reboot instead. Cause basically what ifdown and ifup do in sequence is to restart your Internet Networking.

Look into your Network applet under System > Admin. to find out what your device is called. It might even be eth1 or like that.

Or to avoid all these hassles, simply reboot and you're done setting up OpenDNS.

You can test your OpenDNS after reboot by visiting here:
http://www.opendns.com/buttons/

The 3rd buttons shows you're using OpenDNS if you're successfully using it.

Hi. Thanks for your input. I still can't use Open DNS. Could you do me a "walk-through" of all the steps I need to take?

Thanks

From a terminal, issue the command 'sudo pico /etc/resolv.conf' then remove any current entries and add the following 2 lines:
nameserver 208.67.222.222
nameserver 208.67.220.220
hit <crtl>+<x> to save and exit, then issue the command 'sudo /etc/init.d/networking restart'
You should now be using OpenDNS's DNS servers. This method ensures you use OpenDNS regardless of what your network interface is named.
Thanks,
David P.

David. Tried your suggestion, but unfortunately after rebooting things were back to where they started!

Mark, to view what devices are on, please open your internet connection... and from terminal:
sudo ifconfig -a
copy and paste content here....
Thank you

We should also establish if you are using DHCP on your workstation, and if it is behind a router. If the answer to both is yes, then you should make the opendns changes in your router. Otherwise please lay out the network setup you use.

David Portwood (dzportwood) said : #7

You could also just follow these instructions, then reboot, without worrying about what your network interface is named:
$ sudo cp /etc/resolv.conf /etc/resolv.conf.auto
$ sudo gedit /etc/dhcp3/dhclient.conf
# append the following line to the document
prepend domain-name-servers 208.67.222.222,208.67.220.220;
# save and exit

David. I think I hadn't input the new line correctly - as soon as I did it worked perfectly. Thanks for your help.
