Worried about time? BSDCan early registration ends April 30th! Worried about network time? Henning Brauer is giving the talk: OpenNTPD - 20 years and a few milliseconds later at BSDCan 2026:

OpenNTPD hit the OpenBSD CVS in late 2004. Now, 20 years and a few milliseconds later, it's time to look back, how it was received, and what changed.

We'll briefly look at the world 20 years wrt having systems' clocks synchronized (or not), the design of OpenNTPD and how it fundamentally differed from everything around back then, and how it was - intentionally or not - misunderstood by some with very little knowledge but a lot of opinion, and how FUD from 20 years ago is still around. We'll cover what changed in OpenNTPD after it went public, and what changed in OpenBSD to increase accuracy substantially. We'll also cover the later added constraint feature to further defend against getting fed incorrect time.

Want to learn how to filter packets on BSD? Come see the Network Management with the PF Packet Filter Toolset tutorial!

The OpenBSD Packet Filter (PF) is at the core of the network management toolset available to professionals working with the BSD family of operating systems.

The OpenBSD Packet Filter (PF) is at the core of the network management toolset available to professionals working with the BSD family of operating systems.

Understanding the networking toolset is essential to building and maintaining a functional envirionment. The present session will both teach principles and provide opportunity for hands-on operation of the extensive network tools available on OpenBSD and sister operating systems in a lab environment. Participants will be performing practical excercises in their choice of OpenBSD and FreeBSD environments. Basic to intermediate understanding of TCP/IP networking and basic Unix command line skills are expected and required for this session.

Topics covered include

The basics of and network design and taking it a bit further

Building rulesets

Keeping your configurations readable and maintainable

Seeing what your traffic is really about with your friend tcpdump(8)

Filtering, diversion, redirection, Network Address Translation

Handling services that require proxying (ftp-proxy and others)

Address tables and daemons that interact with your setup through them

The whys and hows of network segmentation, DMZs and other separation techniques

Tackling noisy attacks and other pattern recognition and learning tricks

Annoying spammers with spamd

Basics of and not-so basic traffic shaping

Monitoring your traffic

Resilience, High Availability with CARP and pfsync

Troubleshooting: Discovering and correcting errors and faults

Your network and its interactions with the Internet at large

Common mistakes in internetworking and peering

Keeping the old IPv4 world in touch with the new of IPv6

Are you looking to sharpen your Shell Scripting chops? Then you may be interested in the BSDCan Shell Scripting Tutorial for Beginners and Sysadmins with Mathias Eggers.

Anyone who works with BSD and other Unix- and Linux-like systems will sooner or later have to deal with the shell and shell scripts, e.g. automation of repetitive task or starting services in /etc/rc.d. Understanding scripts and how to meaningfully extend or rewrite them is the goal of this tutorial, which is mainly designed for beginners and sysadmins.

Simple shell scripts often consist of a sequence of arbitrary shell commands executed in a specific order to achieve a particular purpose. This is where the tutorial will begin, and I will then walk participants through the other components of a script using examples:

Variables

Sourcing

Control structures

Loops

In- and output redirection

Parameters and options

Functions

Testing scripts

From the tutorial the participants will get an impression of what could be achieved with the well-equipped toolbox the shell provides and use that knowledge for creating own scripts for their projects.

Participants should bring their own machines to try out the examples. I encourage everybody to ask questions and bring examples or problems from their daily work to the tutorial to foster a vivid discussion.

I've been writing shell scripts as part of my work since I got in contact with Unix in 1993 and have been teaching shell programming to apprentices for over ten years. This tutorial will be a shortened and in regards to rc-scripts extended version of that one-week course.
