How to Install djbdns on Manjaro

Djbdns is a secure and reliable Domain Name System (DNS) software created by Daniel J. Bernstein. It is the default DNS software used in many Linux distributions that require secure and fast DNS resolution.

Requirements

Before we begin, ensure that you have the following requirements:

A Manjaro installation with root access
A stable internet connection

Installation

To install djbdns on Manjaro, follow the steps below:

Open the terminal on your Manjaro system. You can use the shortcut Ctrl + Alt + T.
Install djbdns using the pacman package manager by running the following command:

sudo pacman -S djbdns

After the installation is complete, you need to configure the djbdns software.

First, create a new directory for the configuration files:
```
sudo mkdir -p /etc/djbdns
```
Then, copy the default configuration files to the directory you just created:
```
cd /etc/djbdns
sudo cp /var/lib/djbdns/* .
```
Once you have copied the default configuration files, you need to update them to match your network settings.

Open the data file using your preferred text editor:
```
sudo nano data
```
In the data file, you will see some default entries like this:
```
.:127.0.0.1
localhost.:127.0.0.1
```
You need to replace these entries with your own domain name and IP address records.

For example, suppose your domain name is example.com, and your IP address is 10.0.0.2. You would replace the entries with:
```
.:10.0.0.2
example.com.:10.0.0.2
```
After you have updated the data file, you need to create a root file to define the root of the DNS hierarchy.

Open the root file using your preferred text editor:
```
sudo nano root
```
In the root file, add the following line:
```
example.com:ns.example.com
```
Replace example.com with your domain name, and ns.example.com with the hostname of your DNS name server.
Next, you need to start the tinydns service to make the configuration changes take effect:
```
sudo sv start /var/service/tinydns
```
The tinydns service will now start, and your DNS resolution is now managed by djbdns.

Conclusion

Djbdns can provide secure and reliable DNS resolution for your Manjaro system. By following the steps outlined in this tutorial, you can easily install and configure djbdns on your Manjaro system.
