Still in development, but certainly a step in the right direction. Seems a perfect runabout vehicle to get you to public transportation and to get groceries on the way home. Hopefully wider adoption can bring the price down. It would also function as a grid connected battery as mentioned in this "Living on Earth " segment. https://loe.org/shows/shows.html?programID=24-P13-00035

Upcoming EuroBSDCon OpenBSD talk Confidential Computing with OpenBSD by Hans-Jörg Höxer Confidential computing is a family of techniques to enhance security\ and confidentiality for data in use. One technical approach is strong\ isolation for virtual machines. AMDs Secure Encrypted Virtualization (SEV) offers several feature sets\ for isolation of guest virtual machines from an non-trusted host hypervisor\ and operating system. These feature sets include memory encryption,\ encryption of guest state including CPU registers and an attestation\ framework. In this talk we will explore some of the AMD SEV feature sets. We will\ describe how to use them to run OpenBSD as both * a confidential guest VM and * a host hypervisor providing a confidential execution environment. Topics covered are CPU feature detection, low level kernel initialization,\ memory management, virtio(4) device drivers and the virtual machine\ daemon vmd(8).

Upcoming EuroBSDCon OpenBSD talk Building a SD-WAN appliance suitable for an Australian Health Sector NFP/NGO by Jason Tubnor Latrobe Community Health Service (LCHS) - AS139466 - is a Not for Profit (NFP)/Non-Government Organisation (NGO) headquartered in Victoria, Australia. The organisation consists of 40 offices and 2 data centres across the States of Victoria and New South Wales with over 1,500 employees. All LCHS infrastructure is designed and managed in-house without the use of large-scale cloud infrastructure. Since 2015, BSD Unix has been used for various workloads within the organisation. This talk focuses on our next generation SD-WAN appliance built on OpenBSD technology using commodity hardware. Topics will include the network topology, design choices, various OpenBSD VPN and routing technologies and orchestrating build, deployment and management across the fleet using Ansible.

Upcoming EuroBSDCon OpenBSD talk A Packet's Journey Through the OpenBSD Network Stack by Alexander Bluhm When debugging network issues, it is important to understand when\ certain things happen. Tcpdump provides valuable insight, pf\ transforms packets, pseudo devices add features, and netstat counters\ show action. The call graph of the functions within the kernel is\ the base to comprehend the relation between these sources of\ information. The layering of kernel code in hardware drivers, pseudo devices,\ IP processing, forwarding and protocol layer is explained. The\ kernel provides the socket interface to userland processes. Packet\ forwarding happens within the kernel. Bridge code uses certain\ shortcuts. pf is a swiss knife that can manipulate traffic in\ multiple layers. IPsec has an independent interface that overrides\ routing. Routing itself and neighbor discovery is a necessary step\ that has its tentacles everywhere. Checksum calculation can be\ performed by hardware offloading. By using examples with a single packets, their way through the\ kernel is shown. The possible branches, configuration options, and\ measurement output are put in correlation.

Upcoming EuroBSDCon talk: Why (and how) we're migrating many of our servers from Linux to the BSDs by Stefano Marinelli A few years ago, we decided to migrate many of our servers (and many of those of our clients) from Linux to the BSDs - FreeBSD, OpenBSD, NetBSD - depending on the specific services. In this presentation, I will discuss the reasons behind our decision, the technical and organizational challenges we faced, the tangible benefits we have experienced, and why we believe this migration is successful. I will provide specific examples and real-life case studies. In an increasingly complex world, relying on simple, stable, and secure solutions is becoming more and more important, and the BSDs can make a significant contribution in this direction.

Upcoming EuroBSDCon OpenBSD talk OpenBSD vs. IPv6 by Florian Obser ** .ical](https://events.eurobsdcon.org/2024/talk/AV78U9.ics)09-21, 17:45–18:30 (Europe/Dublin), Foyer B ** We will give an overview of past, present and future work on IPv6 in OpenBSD. We will show how we replaced KAME stack code in both the kernel as well as userland with modern, privilege separated daemons for stateless address auto configuration. slaacd(8) runs on the host to solicit router advertisements and configures addresses and routes. rad(8) runs on the router to send router advertisements. A newly written daemon for DHCPv6, dhcp6leased(8), requests prefixes from an upstream ISP which then can be used by rad(8) for router advertisements. Next we will show the new IPv6 source address selection in the kernel, including support for the infamous Rule 5.5 of RFC 6724. In ongoing and future work we will touch on client-side address translation using pf(4)'s af-to feature to support the 464XLAT transition mechanism for v6-mostly networks.

Upcoming EuroBSDCon talk: vmd's multi-process device emulation: 2 releases later by Dave Voutila [** .ical](https://events.eurobsdcon.org/2024/talk/H7G3CS.ics)09-21, 14:45–15:30 (Europe/Dublin), Foyer B ** In OpenBSD 7.4, the native hypervisor, [vmd(8)](https://man.openbsd.org/vmd.8)became the only open source type-2 hypervisor to default to using a multi-process, privilege separated model for emulating block and network devices. This talk provides a look at the inspiration from Oracle's [contributions](https://blogs.oracle.com/linux/post/multiprocess-qemu-breaking-up-is-hard-to-do) to QEMU as a means of multi-layered defense, a review of the challenges and changes required to OpenBSD across 7.4 and 7.5, and a look at the road ahead.

Upcoming OpenBSD talk: Puffy does Realtime Hypermedia by Patrick Marchand Modern web development is intrinsically tied to javascript and frameworks have been pushing us further and further away from the initial model of the internet as a web of documents. In response to this, libraries like htmx and data-star have arisen to demonstrate ways to use hypermedia to create interactive applications. Hypermedia as the engine of application state (HATEOS) is a driving principle of these new libraries and by allowing the backend to drive the state of the frontend directly without requiring the user to write javascript code, they make it possible to do hypermedia on whatever you like (Otherwise known as the HOWL stack).  That means that with nothing but the OpenBSD base install and a small javascript shim (12kb at the time of writing), we can write realtime hypermedia applications. We will explore the case of a small web application that monitors the state of it's server and offers real time updates of it's metrics.

We're less than two weeks out from BSDCan! Read our latest update here: https://blog.bsdcan.org/2024/ We could use some help with registration, so please volunteer if you're interested in stuffing bags and getting to know other volunteers and the conference team. Let's talk about the first half of the conference: Tutorial Days ​ This is some of the most affordable professional training out there and we're grateful for the talented presenters who have offered their services to the community. We hope you'll check one or two of these sessions out if you're attending in person! If you get in early, Tuesday evening before the these tutorial days start there will be an informal meetup, the famed "Goat BOF," at Father and Sons (fnsottawa.com) where you can get a bite and say hello. For our first tutorial day on Wednesday, you can sign up to learn the basics of BGP with Max Stucchi, and dig deeply into the routing protocol that makes the internet work! (indico.bsdcan.org/event/1/cont…) Or join Tom Smyth to learn about managing OpenBSD networks with NSH, a command-line interface for network appliances. (indico.bsdcan.org/event/1/cont…) Thursday's tutorials include the conference classic introduction to PF by @pitrh, Max and Tom (indico.bsdcan.org/event/1/cont…) and our con chair @mwl will present half day tutorials about TLS (indico.bsdcan.org/event/1/cont…) and the hottest of topics: running your own mail server (indico.bsdcan.org/event/1/cont…). At 5pm on Thursday, after the last tutorials, head on over to the 90 University residence hall and step through the lobby and into the hacker lounge, where we will be handing out registration badges and packets to earlybirds. At 6pm there will be a brief informational Newcomer's Session you don't want to miss, and we hope after that point that con regulars will group up to help take first-time attendees out to see the town! This room will stay open later into the evening so you can hack or visit with friends. Or hack with friends! . . ​ Not registered yet?
