Network Management with the OpenBSD Packet Filter Toolset (T5) EuroBSDCon 2025

The OpenBSD Packet Filter (PF) is at the core of the network management toolset available to professionals working with the OpenBSD and FreeBSD operating systems. Understanding the PF subsystem and the set of networking tools that interact with it is essential to building and maintaining a functional environment. The present session will both teach networking and security principles and provide opportunity for hands-on operation of the extensive network tools available on OpenBSD and FreeBSD in a lab environment. Basic to intermediate understanding of TCP/IP networking is 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 (tcpdump is your friend) 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 The tutorial is lab centered and fast paced. Time allowing and to the extent necessary, we will cover recent developments in the networking tools and variations between the implementations in the OpenBSD and FreeBSD operating systems. Participants should bring a laptop for the hands on labs part and for note taking. The format of the session will be compact lectures interspersed with hands-on lab excercises based directly on the theory covered in the lecture parts. This session is an evolutionary successor to previous sessions. Slides for the most recent version of the PF tutorial session are up at https://nxdomain.no/~peter/pf_fullday.pdf, to be updated with the present version when the session opens.

Look what I found in the #Zagreb City Museum! :%d the dirt from your dishes with #vim, it was never easier!

Several old Croatian advertisement posters for "VIM", which seems to be some kind of dish-washing agent.

Turns out - I have an extra ticket for #EuroBSDCon2025 (including the social event). Instead of refunding it, I would like to give it away for free to whoever would like it - ideally to someone around the area of the event who could not make it otherwise (no questions asked).

Send me a DM if you're interested. :)
