    Default Split DNS and Ubuntu Server 12.04 LTS problems

    I'm installing Zimbra with a Split DNS setup but I'm running into some significant issues getting the server to see the outside world (e.g. ping google) and resolve the internal DNS appropriately also.

    In the wiki page on Split DNS (since I've re-read it multiple times) it mentions editing resolv.conf. The issue however is that resolv.conf is automatically generated in Ubuntu Server 12.04 and the wiki makes no mention of that. It's been supremely frustration so perhaps it would be good for someone to review the steps in light of that fact and edit the wiki where necessary.

    So the question is, in Ubuntu Server 12.04, do I add the dns-search domain to the /etc/network/interfaces file or do I add them to /etc/resolvconf/resolv.conf.d/head?

    Also, I have other nameservers set up in my interfaces file

    Doesn't that only happen if you don't have a fixed IP.

    Yet another reason I don't like Ubuntu.

    Who, or what, configured those?

    Fixed IPs are pretty common in server environments.

    I'm not all that familiar with the differences between server distros like Ubuntu Server or CentOS

    I had to configure the additional nameservers since DNS outside of my NAT wasn't resolving and I couldn't ping google. I've had a a hell of a time even getting fixed IPs to work on this thing.
