How to Install SPF Toolbox on OpenBSD

SPF Toolbox is a handy tool that allows you to check the SPF record for a domain. In this tutorial, we will be discussing how to install SPF Toolbox on OpenBSD.

Prerequisites

Before we start, make sure that you have the following:

  • A computer running OpenBSD
  • Root access on the computer
  • An internet connection

Step 1: Install Go

SPF Toolbox is developed in Go, so we need to install it first. OpenBSD includes the Go compiler in its base system. To install it, run the following command:

# pkg_add go

This will install Go on your system.

Step 2: Download and install SPF Toolbox

To download and install SPF Toolbox, follow these steps:

  1. Create a new directory for SPF Toolbox, and change into it:
$ mkdir spf-toolbox
$ cd spf-toolbox
  1. Download the source code for SPF Toolbox using the following command:
$ fetch https://github.com/mengzhuo/spftoolbox/archive/master.zip
  1. Unzip the downloaded file:
$ unzip master.zip
  1. Change into the spftoolbox directory:
$ cd spftoolbox-master
  1. Compile SPF Toolbox using the go command:
$ go build

This will create an executable file called spftoolbox in the current directory.

  1. Move the executable to the /usr/local/bin directory:
# mv spftoolbox /usr/local/bin

SPF Toolbox is now installed on your OpenBSD system.

Step 3: Use SPF Toolbox

To use SPF Toolbox, simply run the spftoolbox command followed by the domain you want to check. For example:

$ spftoolbox example.com

This will display the SPF record for the domain.

That's it! You have successfully installed and used SPF Toolbox on OpenBSD.
