How to Install Knot DNS on OpenBSD

Knot DNS is a high-performance, authoritative-only DNS server that can be quickly installed on OpenBSD. In this tutorial, we will guide you through the process of installing Knot DNS on OpenBSD.

Prerequisites

• A running OpenBSD system
• Root access to the system
• An active internet connection

Step 1: Install Dependencies

The first step is to install the dependencies required for installing Knot DNS on OpenBSD.

$ sudo pkg_add -I libxml2 libedit libtool libuv gcc git

Step 2: Download Knot DNS Source Code

In this step, we will download Knot DNS source code from the official website.

$ git clone https://gitlab.labs.nic.cz/knot/knot-dns.git

Step 3: Compile and Install Knot DNS

After downloading the Knot DNS source code, navigate to the directory where it is saved and run the following commands to build and install Knot DNS.

$ cd knot-dns
$ ./bootstrap.sh
$ mkdir build
$ cd build
$ ../configure --prefix=/usr/local --sysconfdir=/etc/knot --localstatedir=/var
