In this tutorial, you will learn how to install Knot DNS, a high-performance authoritative-only DNS server, on the latest version of NixOS.
Before you begin, you will need the following:
You can install Knot DNS by running the following command in your terminal:
sudo nix-env -i knot
This will download and install Knot DNS on your NixOS system.
Once Knot DNS is installed, you need to configure it to use it as an authoritative-only DNS server.
sudo nano /etc/knot/knot.conf
server:
listen: [::]:53
rundir: /var/run/knot/
storage: "/var/lib/knot/"
log:
syslog: yes
severity: info
trace: no
acl:
acl_localnets: 127.0.0.1/32 ::1/128 192.168.0.0/16
template:
template_localnets: &template_localnets {
acl: acl_localnets
}
acl:
acl_my-network: 192.168.100.0/24
acl_dyn-block: !auth * *
zone:
- domain: "example.com"
file: "/etc/knot/example.com.zone"
template: *template_localnets
acl: [ acl_my-network, acl_dyn-block ]
In the above configuration file, the acl_localnets
section defines a list of IP addresses that are allowed to access the server. The template_localnets
section is a named configuration that includes the acl_localnets
list, and it is referenced by the zone
section.
To start the Knot DNS server, run the following command:
sudo systemctl start knot
You can then confirm that Knot DNS is running by checking its status:
sudo systemctl status knot
Now you know how to install Knot DNS and configure it as an authoritative-only DNS server on the latest version of NixOS. Enjoy using Knot to manage and secure DNS queries!
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
