How to Install BIND on Elementary OS

BIND (Berkeley Internet Name Domain) is an open-source Domain Name System (DNS) software used to translate domain names into IP addresses. This tutorial will guide you through the process of installing BIND on the latest version of Elementary OS.

Prerequisites

Before you start, make sure you have the following:

• Elementary OS installed
• An active internet connection
• A user account with sudo privileges

Step 1: Update packages

Start by updating your system's package list:

sudo apt-get update

Step 2: Installing BIND

Run the following command to install BIND:

sudo apt-get install bind9

This will install the latest version of BIND along with any dependencies.

Step 3: Configure BIND

After installation, you need to configure BIND. The configuration files for BIND are located in the /etc/bind/ directory.

Open the /etc/bind/named.conf.options file using your favorite text editor:

sudo nano /etc/bind/named.conf.options

Replace the options section with the following:

options {
        directory "/var/cache/bind";
        recursion yes;
        allow-recursion { localnets; localhost; };
        forwarders {
                8.8.8.8;
                8.8.4.4;
        };
        dnssec-validation auto;
        auth-nxdomain no;    # conform to RFC1035
        listen-on-v6 { any; };
};

Save and close the file.

Step 4: Start BIND

Start the BIND service using the following command:

sudo systemctl start bind9

To check the status of the service to make sure it started correctly, run:

sudo systemctl status bind9

Step 5: Verify BIND is functioning

Run the following command to verify that BIND is functioning:

dig example.com

Replace example.com with the domain you want to look up. The output should display the IP address associated with the domain.

Congratulations! You have successfully installed and configured BIND on your Elementary OS system.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
