We'll cover when packets are inspected, when rules are evaluated and how states are used. Along the way we'll cover what DTrace probes can show us, what some of pfctl's counters mean and just how many times pf can look at a single packet. This talk is intended for firewall admins looking for a deeper understanding and aspiring pf developers. It is not a "How to use pf" talk. early25-8-a-packet-s-journey-through-pf Kristof Provost en false https://events.bsdnl.nl/early25/talk/WDHDZY/ https://events.bsdnl.nl/early25/talk/WDHDZY/feedback/ Pandora Talk 2025-04-12T13:30:00+02:00 13:30 01:00 In this talk, we'll take a visual and educational journey to the stars. We'll follow the adventures of the spaceship BSD-NL 2025 (since NCC-1701 was already taken) on their voyage of exploration. From its humble beginnings at the space dock, we'll see how ZFS was integrated into the ships systems and how the chief storage engineer saved the crew numerous times during their encounters in (disk) space. Come along for the ride and learn all about the cool features that ZFS provides. You may think this is all science-fiction technology, yet it is available right here and now, for free. early25-6-disk-space-the-final-frontier Benedict Reuschling en I've been teaching ZFS and its concepts for a number of years in a classic, text-heavy slide presentation style. While this was successful, I noticed that over the years, it was hard to keep the audience's attention over a longer period of time. With the availability of image generators, I thought I'd flip this around: creating a visually appealing presentation of these topics with the learning objectives woven into story of space exploration. The more and more images that were generated, the more ideas I got, sparking my creativity like never before. This resulted in the presentation you're going to see. Basic concepts of ZFS (pools, datasets, RAID-levels, compression, snapshots) are presented in a visual style, both appealing to the audience and getting the points across at the same time. With this talk, I hope I can motivate others to abandon text-heavy slide presentations and move towards a visual style of demonstrating their topic. The story driven approach helps the audience see the benefits of ZFS (in this case) and allows them to learn the basics in a way that is fun and interesting. false https://events.bsdnl.nl/early25/talk/VKEQJW/ https://events.bsdnl.nl/early25/talk/VKEQJW/feedback/
