Installing NSD on MXLinux Latest

Introduction

NSD (Name Server Daemon) is an open-source, fast, and lightweight DNS server that provides DNSSEC support. In this tutorial, we will guide you on how to install NSD on MXLinux Latest.

Prerequisites

Before starting the installation process, make sure that your system is up to date and you have sudo privileges.

Step 1: Install NSD

To install NSD on MXLinux Latest, open the terminal and execute the following command:

sudo apt-get install nsd

This command will install NSD along with its dependencies.

Step 2: Configure NSD

Once the installation process completes, we need to configure NSD to start serving DNS requests.

Open the NSD configuration file in your preferred text editor. In this example, we will use nano.

sudo nano /etc/nsd/nsd.conf

Configure NSD to listen on your server's IP address by modifying the following line:

server:
  ip-address: <your_server_IP_address>
  port: 53

Next, we need to define the DNS zones that the server will serve. For example, to serve a domain example.com, add the following zone configuration:

zone:
  name: "example.com"
  zonefile: "/etc/nsd/zones/example.com.zone"

Create a zone file for the domain and add the necessary DNS records:

sudo nano /etc/nsd/zones/example.com.zone

$TTL 3600
@       IN      SOA     ns1.example.com. admin.example.com. (
                        2019031400      ; serial, todays date+todays
                        3600            ; refresh, seconds
                        1800            ; retry, seconds
                        604800          ; expire, seconds
                        3600            ; minimum, seconds
                        )
                IN      NS      ns1.example.com.

ns1             IN      A       <your_server_IP_address>
www             IN      A       <your_server_IP_address>

Save and close the file.

Step 3: Start NSD

Restart the NSD service to apply the changes:

sudo systemctl restart nsd

Check the status of the NSD service:

sudo systemctl status nsd

If everything is configured correctly, you will see a status message indicating that NSD is running.

Conclusion

In this tutorial, we installed and configured NSD on MXLinux Latest. You can now use NSD as your DNS server and take advantage of its high performance and DNSSEC support.
