How to Install and Configure Bind9 DNS on Ubuntu 11.10

BIND, standing for “Berkeley Internet Name Domain”, is the most widely utilized Domain Name System (DNS) software on the internet for providing DNS services.

This tutorial will guide you through the process of installing and configuring BIND 9 DNS service on an Ubuntu server. The steps are designed for Ubuntu 11.10, but they may also be applicable to other versions with minor adjustments.

Step 1: Install BIND 9

To install BIND 9, open your terminal and run the following command:

sudo apt-get install bind9 -y

Step 2: Set Up and Configure a Zone

Next, you’ll need to set up and configure a zone. In this example, we’ll use “webhostinggeeks.local” as the zone name. To do this, open the named.conf.local file with the following command:

sudo vim /etc/bind/named.conf.local

Add a DNS zone to BIND9 by editing the named.conf.local file as shown below:

//
// Do any local configuration here
//
// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";
zone "webhostinggeeks.local" {
 type master;
 file "/etc/bind/db.webhostinggeeks.local";
 };
~

Step 3: Use an Existing Zone File as a Template

Copy an existing zone file and use it as a template for your new zone file. To do this, run the following command:

sudo cp /etc/bind/db.local /etc/bind/db.webhostinggeeks.local

Next, edit the new zone file db.webhostinggeeks.local:

sudo vim /etc/bind/db.webhostinggeeks.local

Change the configuration as shown below:

;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA ns.webhostinggeeks.local. root.webhostinggeeks.local. (
 2 ; Serial
 604800 ; Refresh
 86400 ; Retry
 2419200 ; Expire
 604800 ) ; Negative Cache TTL
;
@ IN NS ns.webhostinggeeks.local.
ns IN A 192.168.1.49
box IN A 192.168.1.49

Step 4: Restart BIND 9

Any changes made to the zone file will require BIND9 to be restarted before they take effect. To restart BIND9, run the following command:

sudo /etc/init.d/bind9 restart

Step 5: Point Your Server to the DNS Server

Ensure that your workstation or server ispointing to the DNS server. In this case, the Ubuntu server should point to itself since it’s running BIND9. To do this, edit the /etc/resolv.conf file:

sudo vim /etc/resolv.conf

Then, add the following line to the file:

nameserver 127.0.0.1

Step 6: Test Your BIND 9 Server

Finally, test your BIND9 server to ensure it’s working correctly. To do this, run the following commands:

nslookup
> set type=ns
> webhostinggeeks.local

The output should look something like this:

Server: 127.0.0.1
Address: 127.0.0.1#53
webhostinggeeks.local nameserver = ns.webhostinggeeks.local.
