How to Install djbdns on Linux Mint

djbdns is an easy-to-use, secure, and reliable Domain Name System (DNS) software, designed to offer private and public DNS services to Internet users. It is an ideal solution for people who want to control their DNS services.

In this tutorial, we will go through the steps to install djbdns on your Linux Mint system.

Step 1: Requirements

Before installing djbdns, you need to make sure that your system meets the following requirements:

• A Linux Mint system with administrative privileges
• An Internet connection

Step 2: Download djbdns

Open your terminal and navigate to the directory where you want to download djbdns. Then use the wget command to download the latest version of djbdns:

$ cd /tmp
$ wget http://cr.yp.to/djbdns/djbdns-1.05.tar.gz

Step 3: Extract djbdns

Once the download is complete, extract the contents of the tarball using the tar command:

$ tar xzf djbdns-1.05.tar.gz

Step 4: Build djbdns

Next, change into the extracted directory and build the software using the make command:

$ cd djbdns-1.05
$ make

Step 5: Install djbdns

After the software has been built, install it by running the following command:

$ make setup check

This will install djbdns into the /usr/local directory.

Step 6: Configure djbdns

To configure djbdns, create a tinydns directory under /etc:

$ sudo mkdir /etc/tinydns

Then create a data directory and a root file inside the tinydns directory:

$ sudo mkdir /etc/tinydns/data
$ sudo touch /etc/tinydns/root

Create the data file

Open your favorite text editor and create a data file inside the tinydns/data directory:

$ sudo nano /etc/tinydns/data

Add the DNS records that you want to serve. Here is an example configuration:

example.com:192.168.1.10:86400
www.example.com.192.168.1.10:86400

This configuration would serve the IP address 192.168.1.10 for the example.com and www.example.com domains.

Create the run file

Create a run file inside the tinydns directory:

$ sudo nano /etc/tinydns/run

Add the following code:

#!/bin/sh
exec /usr/local/bin/tinydns

Make the run file executable:

$ sudo chmod +x /etc/tinydns/run

Step 7: Start the tinydns service

Start the tinydns service by running the following command:

$ sudo /etc/tinydns/run

Your computer is now serving DNS requests for the domains configured in the data file.

Conclusion

In this tutorial, you have learned how to install and configure djbdns on Linux Mint. This software is a reliable and secure solution for those who want to control their DNS services.
