Setting up local DNS server using bind and webmin

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. A Domain Name Service resolves queries for these names into IP addresses for the purpose of locating computer services and devices worldwide.

BIND is the most widely used DNS software on the Internet. On Unix-like operating systems it is the de facto standard.

I am using Ubuntu 16.04 and the first step is to edit the host file:

nano /etc/hosts

Make it more like this

127.0.0.1       localhost
192.168.1.250   ns1.example.com

Install Bind9 DNS server

apt-get install bind9 bind9utils bind9-doc

Add the webmin repositories to sources.list and install webmin

echo "deb http://download.webmin.com/download/repository sarge contrib" >> /etc/apt/sources.list.d/webmin.list
echo "deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib" >> /etc/apt/sources.list.d/webmin.list
wget -O - http://www.webmin.com/jcameron-key.asc | apt-key add -
apt-get update
apt-get install -y webmin

After the installation you can login here

https://ns1.example.com or https://192.168.1.250

Browse Webmin->Webmin Servers Index to configure the webmin server.

Basic setup of DNS server

Create master zone: Servers -> BIND DNS Server -> Create Master Zone

Again to create the reserver zone

Create forwarding and transfers: Servers -> BIND DNS Server	-> Forwarding and Transfer

Now, we can add the server record.

Here is the example of setting tup.

Next post, we may set up the secondary DNS.
