I'd like to install on Ubuntu 12.04 a DNS server using BIND9.
As a first step, I'd just like to configure it as a forwarder for my box
only.
This is what I do:
1. I deactivate `dnsmasq` editing
`/etc/NetworkManager/NetworkManager.conf` by commenting the `dns=dnsmasq`
line.
Before, the `/etc/resolv.conf` file contained a `nameserver 127.0.0.1`
line, and now there is a `nameserver 10.0.2.3` line (my actual DNS server
working in a VirtualBox environment). I think it's right, and name
resolution (using `dig`) still works.
2. I download BIND9 and the suggested packages with `sudo apt-get install
bind9 bind9utils bind9-doc`
3. In `/etc/bind/named.conf.options` I edit the
// forwarders {
// 0.0.0.0;
// };
block with the
forwarders {
10.0.2.3;
};
block.
4. In `/etc/dhcp/dhclient.conf` I de-comment the `#prepend
domain-name-servers 127.0.0.1;` line; using DHCP for my network interface,
this allows to have `nameserver 127.0.0.1` as first line on
`/etc/resolv.conf`; if I had a static configuration, I would just add a
`dns-nameservers 127.0.0.1` line in `/etc/network/interfaces`.
5. Now I restart all services (resolvconf, dhclient, bind9).
Well, from this point nothing works.
Using Wireshark I can see a lot of DNS queries to/from 10.0.2.3 and also
to/from root-servers, but `dig` continues to fail with `status: SERVFAIL`.
Why?
