All hope seemed lost until the Summer of 2017, when a fellow OpenBSD developer was contacted by a generous user (Thanks again, Lars!) offering to donate two Lemote Fuloong machines, and I was lucky enough to get one of those units.

NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines FreeBSD Network Troubleshooting (https://klarasystems.com/articles/freebsd-network-troubleshooting-understanding-network-performance/) FreeBSD has a full set of debugging features, and the network stack is able to report a ton of information. So much that it can be hard to figure out what is relevant and what is not.

NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines Tracing the History of ARM and FreeBSD (https://klarasystems.com/articles/tracing-the-history-of-arm-and-freebsd/) When we think of computers, we generally think of laptops and desktops. Each one of these systems is powered by an Intel or AMD chip based on the x86 architecture. It might feel like you spend all day interacting with these kinds of systems, but you would be wrong. Unix Tip: Make ‘less’ more friendly (https://ascending.wordpress.com/2011/02/11/unix-tip-make-less-more-friendly/) You probably know about less: it is a standard tool that allows scrolling up and down in documents that do not fit on a single screen. Less has a very handy feature, which can be turned on by invoking it with the -i flag. This

While still a nice introduction, the book by Adrian Cockcroft has become dated — claimed Roland in 2003, which believe it or not was 18 years ago... dRAID, Finally! (https://klarasystems.com/articles/openzfs-draid-finally/) Admins will often use wide RAID stripes to maximize usable storage given a number of spindles. RAID-Z deployments with large stripe widths, ten or larger, are subject to poor resilver performance for a number of reasons.

NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines Follow-up about FreeBSD jail advantages (https://rubenerd.com/follow-up-about-freebsd-jail-advantages/) I’ll admit I ran a lot of justifications together into a single paragraph because I wanted to get to configuring the jails themselves. They’re also, by and large, not specific to FreeBSD’s flavour of containerisation, though I still think it’s easily the most elegant implementation. Sometimes the simplest solution really is the best one.

(https://www.howtogeek.com/440147/did-linux-kill-commercial-unix/) Sales of commercial Unix have fallen off a cliff. There has to be something behind this dramatic decline.

NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines A Week With Plan 9 (https://thedorkweb.substack.com/p/a-week-with-plan-9) I spent the first week of 2021 learning an OS called Plan 9 from Bell Labs. This is a fringe Operating System, long abandoned by it’s original authors. It's also responsible for a great deal of inspiration elsewhere. If you’ve used the Go language, /proc, UTF-8 or Docker, you’ve used Plan 9-designed features. This issue dives into Operating System internals and some moderately hard computer science topics. If that sort of thing isn’t your bag you might want to skip ahead. Normal service will resume shortly.

A 'must have' security tool! (https://undeadly.org/cgi?action=article;sid=20210119113425) Pf-badhost is a very practical, robust, stable and lightweight security script for network servers. It's compatible with BSD based operating systems such as {Open,Free,Net,Dragonfly}BSD and MacOS. It prevents potentially-bad IP addresses that could possibly attack your servers (and waste your bandwidth and fill your logfiles), by blocking all those IPs contacting your server, and therefore it makes your server network/resources lighter and the log

I don't know how KV works day to day, but it seems pretty clear that the status quo has changed at most workplaces in the last several months, and it's hard to know if there are things we could be doing to stay productive while we're all at home, ordering delivery, and microwaving our mail.

VLANs are common place, and if you have done some network management or design then you are likely to have interacted with them. The second are FreeBSDs VNET virtual network stacks, a powerful network stack isolation technology that gives FreeBSD jails super powers. Ethernet VLAN (standardised by IEEE 802.1Q) are an extension to Ethernet and provide an essential method for scaling network deployments. They are used in all environments to enable reuse of common infrastructure by isolating por

Briggs Memorial Scholarship (http://blog.netbsd.org/tnf/entry/allen_k_briggs_memorial_scholarship) Allen Briggs was one of the earliest members of the NetBSD community, pursuing his interest in macBSD, and moving to become a NetBSD developer when the two projects merged. Allen was known for his quiet and relaxed manner, and always brought a keen wisdom with him; allied with his acute technical expertise, he was one of the most valued members of the NetBSD community. The Allen K.

NOTES This episode of BSDNow is brought to you by Tarsnap (https://www.tarsnap.com/bsdnow) Headlines The Origin of the Shell (https://multicians.org/shell.html) CTSS was developed during 1963 and 64. I was at MIT on the computer center staff at that time. After having written dozens of commands for CTSS, I reached the stage where I felt that commands should be usable as building blocks for writing more commands, just like subroutine libraries. Hence, I wrote "RUNCOM", a sort of shell driving the execution of command scripts, with argument substitution. The tool became instantly most popular, as it became possible to go home in the evening while leaving behind long runcoms executing overnight. It was quite neat for boring and repetitive tasks such as renaming, moving, updating, compiling, etc. whole directories of files for system

Along with quite a lot of new features, the announcement brings an end to the former distinction between "ZFS on Linux" and ZFS elsewhere (for example, on FreeBSD). This move has been a long time coming—the FreeBSD community laid out its side of the roadmap two years ago—but this is the release that makes it offici
