Frederic Cambus (fcambus@) has published an article on his blog about the work that has been done to improve the text-console experience on OpenBSD. Well worth a read if, as a proper UNIX-sysadmin, you enjoy working in a text-only environment; but also if you spend most of your time in X!

Since we reported the first bits of powerpc64 support going into the tree on 16 May, work has progressed at a steady pace, resulting in snapshots now being available for this platform.So, if you have a POWER9 system idling around, go to your nearestmirrorand fetch this snapshot. Keep in mind that as this is still very early days, very little handholding is available - you are basically on your own.Read more…

I presented a talk on how I used OpenBGPd as a control plane for my ISP. I cover areas such as Routing fundamentals, a lightning introduction to BGP. An interesting aspect of the design is how the OpenBSD / OpenBGPdis used to control the routing information in my ISP yet theforwarding of packets is offloaded to hardware Layer 3 switches. I also outline my favourite new feature of OpenBGPd max prefix outwhich I'm sure will save my blushes if/when I fat finger my Prefix filters(although if my hair cut is anything to go by it is clear I have no shame anyway!).You can check out the talk here!Tom would welcome comments and feedback on the talk.I hope the talk will help others in deploying OpenBGPd and OpenBSD in their networks.I would also suggest that those interested in learning more about OpenBGPdcheck out Peter Hessler's Tutorial on OpenBGPd which served as anessential aid in getting comfortable in configuring BGP on OpenBSD / OpenBGPd.Peter usually runs the Tutorial in advance of BSD Conferences.I would like to give a big shout out to the people who write thecode in OpenBSD and OpenBGPd, and that your effort makes my life runningmy network and ISP easier.A huge word of thanks is due to Dan Langielle and theBSDCAN2020 Volunteers who organised the virtualBSDCAN 2020 conference this yearin quite difficult circumstances.

I had the pleasure ofsitting with Bob Beckat EuroBSDCon2018 in Bucharest and asking him some questions about theOpenBSD Project, its approaches and some of his favouriteaspects of the Operating System and its projects. Bobpatiently outlines the hows and whys of his involvementin the BSD project.Tom and Bob conduct a post-mortem on a training course onLibTLS Bob Delivered (excellently) in EuroBSDCon & BSDCAN.Bob discusses what online services he used in class fortraining students on LibTLS and why it can be a veryeffective teaching aid.Bob modestly plays down his ability to churn out LibTLS Developers.Bob also gives guidance on the approaches to contributing to the project.Bob reveals the code he least likes working on and why.Bob lets us know what he really thinks about documentation and its value to the community.Bob outlines an example of applying lessons learned from one bug to inform audits looking for similar bugs elsewhere in the OS and the software ecosystem that it supports.I enjoyed making the interview with Bob who answered thequestions with a remarkable combination of purpose and humour.Bob thanks again for your time, and putting up with myinterruptions and jokes :)
