How do I add new nameservers in 12.04?

[VMOS]

for our servers we use 3 nameservers, 1 gets added when the server is built and we put the other 2 into /etc/resolv.conf

I've just built a 12.04 server and when I open resolv.conf, it tells me

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

Hmmmmm

So I added the new ones into /etc/network/interfaces but I can't get them into resolv.conf.

If I run resolvconf -u, I get this error

resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything.


I've tried a few other things but nothing that's even produced an error. any suggestions?

I haven't had anything overwrite the resolv.conf on Ubuntu server 12.04. Desktop, yes, but not server.

Just add them to /etc/resolv.conf and go from there.

You can just add them to resolv.conf but i believe it resets on reboot.

You would be right.

You can uninstall resolvconf and reboot then edit your name servers, or you can just use resolvconf to add them:

Please refer to the Ubuntu server guide: https://help.ubuntu.com/12.04/server...ame-resolution

It should work adding the information to your interfaces file, but you would need to re-start the interface or re-boot he computer to have it take effect (I think).

Resolvconf is actually set through /etc/network/interfaces. You set up your interface then specify your dns-nameservers, dns-search and a domain if you like. On reboot, resolvconf will pick up these details and populate /etc/resolv.conf


You can force the reset by restarting your network.

Found this, which resolved most of the issues i was having

In my case the service resolvconf was installed with 12.04 and I ended up having to add the lines to the file /etc/resolvconf/resolv.conf.d/base for them to stay.

Did you install the server version of 12.04 or one of the desktop versions? As Charles says, I'm pretty sure the server version doesn't use the resolvconf/dnsmasq setup found on the desktop versions.

However the "official" method to add nameserver entries if your machine is using the resolvconf method is to add them into /etc/network/interfaces like this:

auto eth0 
iface eth0 inet static  
address 192.168.1.2  
gateway 192.168.1.1
network 192.168.1.0  
broadcast 192.168.1.255
dns-nameservers 8.8.8.8 8.8.4.4

Note the "s" at the end of "nameservers". You need to use "nameservers" even if you have only one.

Thanks for this information! I am running ubuntu 12.10 behind a old zonet router. I could ping IP but not domain names. This did the trick.
