Yadifa is a lightweight and fast DNS server that supports DNSSEC validation. It is an open-source project and can be installed on various Linux distributions, including Debian. In this tutorial, we will learn how to install Yadifa on Debian latest.
Before proceeding with the installation process of Yadifa, you need to check if your system has the following prerequisites installed:
Before installing Yadifa DNS server, we need to update the Debian system to the latest version. To do so, open the terminal and execute the following command:
sudo apt update
sudo apt upgrade
This command will update the system and upgrade all installed packages to the latest versions.
To install Yadifa DNS server package on Debian, we need to add its repository to our system.
Run the following command to do so:
sudo sh -c 'echo "deb http://ftp.yadifa.eu/debian jessie main" > /etc/apt/sources.list.d/yadifa.list'
This command will create a new file /etc/apt/sources.list.d/yadifa.list and append the Yadifa repository URL to it.
Now, update the package lists by running the following command:
sudo apt update
Next, install the Yadifa DNS server by running the following command:
sudo apt install yadifa
This command will download and install Yadifa DNS server on our Debian system.
After installing Yadifa DNS server, we need to configure it to make it work.
Open the Yadifa configuration file /etc/yadifa/yadifa.conf using your favorite text editor:
sudo nano /etc/yadifa/yadifa.conf
Change the following parameters in the configuration file:
listen-on: Set it to the IP address of the network interface that you want Yadifa to listen on (for example, 192.168.1.10).zone: Define the DNS zone that Yadifa will serve (for example, example.com). We will create this zone in the next step.file: Define the path to the zone file that contains the DNS records for our DNS zone. We will create this file in the next step.Save the changes and exit the editor.
After configuring Yadifa, we need to create a DNS zone and its records.
Open the Yadifa zone file /etc/yadifa/example.com.zone using your favorite text editor:
sudo nano /etc/yadifa/example.com.zone
Add the following lines to the zone file:
$ORIGIN example.com.
$TTL 86400
@ IN SOA ns1.example.com. admin.example.com. (
2021091001 ; serial
86400 ; refresh
7200 ; retry
3600000 ; expire
86400 ; minimum
)
@ IN NS ns1.example.com.
ns1 IN A 192.168.1.10
@ IN MX 10 mail.example.com.
mail IN A 192.168.1.20
Save the changes and exit the editor.
After configuring the DNS zone and records, we can start the Yadifa DNS server:
sudo systemctl start yadifa
To enable Yadifa to start automatically at boot time, run the following command:
sudo systemctl enable yadifa
To test the Yadifa DNS server, run the following command:
dig @localhost example.com
This command will perform a DNS query for the example.com domain name and show the response from the Yadifa DNS server.
In this tutorial, we have learned how to install and configure Yadifa DNS server on Debian latest. Yadifa is a lightweight and fast DNS server that supports DNSSEC validation and can be used for various purposes, including serving DNS zones and resolving DNS queries.
