Step 2: Install Knot DNS

After adding the repository, update your package list and install Knot DNS by running the following command:

$ sudo apt update
$ sudo apt install knot-dns

Step 3: Configure Knot DNS

Once the installation is complete, it's time to configure Knot DNS. The configuration files are located in '/etc/knot/'.

First, backup the default configuration file by renaming it:

$ sudo mv /etc/knot/knot.conf /etc/knot/knot.conf.bak

Next, create a new configuration file by running the following command:

$ sudo nano /etc/knot/knot.conf

Paste the following configuration into the file:

server:
    listen: [::1, 0.0.0.0]
    user: knot
    group: knot

log:
    - target: syslog
      any: info

zone:
    - domain: .
      acl: 0.0.0.0/0

Save the file and exit.

Step 4: Start the Knot DNS service

$ sudo systemctl start knot

To check the status of the Knot DNS service, run:

$ sudo systemctl status knot

Conclusion

At this point, you should have successfully installed Knot DNS on your Linux Mint machine. You can now use the Knot DNS server as your authoritative DNS server.
