OpenBSD Jumpstart

OpenBSD Jumpstart is a compact learning resource aimed at people who are new to OpenBSD and want to get a working system without reading scattered documentation first. It positions itself as a starting point rather than an exhaustive reference, and its chapter structure reflects that intent: each section introduces one area of day-to-day administration and moves on.

The material walks through installation, networking, the PF firewall, user management, packages, services, web hosting, virtual machines, updating, filesystems, kernels, and tuning. Later chapters point to useful packages and external resources, and a bonus section rounds out the guide. The same content is also offered as slides, which helps readers who prefer a presentation-style overview or want to teach the material to others.

This guide fits readers who already have basic UNIX familiarity and want to understand how OpenBSD differs in practice, especially its security-focused design and in-house tools such as OpenSSH, OpenSMTPD, and LibreSSL. It is less suited to experienced administrators seeking deep coverage of edge cases or kernel internals.

A sensible approach is to read the early chapters in order, then use the later ones as checklists while setting up a test machine or VPS. Because the guide targets version 8.0, readers should verify commands against current release notes before applying them to production systems.
