DNS

The Domain Name System is really a must for any TCIP/IP network. It is a key component of the network. That is why it is the first service we will configure.

Here we will be using Bind, ISC's DNS server. Bind has a master/slave configuration, where the master gets the DNS changes and then updates the slave. It cannot run truly redundant, in the sense that only the master is allowed to get DNS changes, if the master is down, the slave cannot be updated.

DNS Master

Network

Since looking up the DNS servers IP-address does not make any sense, we will give the DNS server a statc IP-address. Edit /etc/networking/interfaces and make the following changes.

# The primary network interface
#allow-hotplug eth0
#iface eth0 inet dhcp

auto eth0
iface eth0 inet static
        address 192.168.1.34
        netmask 255.255.255.0
        gateway 192.168.1.1
        network 192.168.1.0
        gateway 192.168.1.1

Install BIND

apt-get install bind9

Configure BIND

Add the new zone file to /etc/bind/named.conf.local

include "/etc/bind/named.conf.kallenberg.dk";
