Enabling FreeBSD on AArch64

• One of the things the FreeBSD foundation has been dumping money into lately is ARM64 support, but we haven't heard too much about it - this article should change that
• Since it's on a mainstream ARM site, the article begins with a bit of FreeBSD history, leading up to the current work on ARM64
• There's also a summary of some of the ARM work done at this year's BSDCan, including details about running it on the Cavium ThunderX platform (which has 48 cores)
• As of just a couple months ago, dtrace is even working on this new architecture
• Come 11.0-RELEASE, the plan is for ARM64 to get the same "tier 1" treatment as X86, which would imply binary updates for base and ports - something Raspberry Pi users often complain about not having ***

OpenBSD's tcpdump detailed

• Most people are probably familiar with tcpdump, a very useful packet sniffing and capturing utility that's included in all the main BSD base systems
• This video guide is specifically about the version in OpenBSD, which has gone through some major changes (it's pretty much a fork with no version number anymore)
• Unlike on the other platforms, OpenBSD's tcpdump will always run in a chroot as an unprivileged user - this has saved it from a number of high-profile exploits
• It also has support for the "pf.os" system, allowing you to filter out operating system fingerprints in the packet captures
• There's also PF (and pflog) integration, letting you see which line in your ruleset triggered a specific match
• Being able to run tcpdump directly on your router is pretty awesome for troubleshooting ***

More FreeBSD foundation at BSDCan

• The FreeBSD foundation has another round of trip reports from this year's BSDCan
• First up is Kamil Czekirda, who gives a good summary of some of the devsummit, FreeBSD-related presentations, some tutorials, getting freebsd-update bugs fixed and of course eating cake
• A second post from Christian Brueffer, who cleverly planned ahead to avoid jetlag, details how he got some things done during the FreeBSD devsummit
• Their third report is from our buddy Warren Block, who (unsurprisingly) worked on a lot of documentation-related things, including getting more people involved with writing them
• In true doc team style, his report is the most well-written of the bunch, including lots of links and a clear separation of topics (doc lounge, contributing to the wiki, presentations...)
• Finally, the fourth one comes to us from Shonali Balakrishna, who also gives an outline of some of the talks
• "Not only does a BSD conference have way too many very smart people in one room, but also some of the nicest." ***

DragonFly on the Chromebook C720

• If you've got one of the Chromebook laptops and weren't happy with the included OS, DragonFlyBSD might be worth a go
• This article is a "mini-report" on how DragonFly functions on the device as a desktop, and
• While the 2GB of RAM proved to be a bit limiting, most of the hardware is well-supported
• DragonFly's wiki has a full guide on getting set up on one of these devices as well ***

News Roundup

Introducing LiteBSD

• We definitely don't talk about 4.4BSD a lot on the show
• LiteBSD is "a variant of [the] 4.4BSD operating system adapted for microcontrollers"
• If you've got really, really old hardware (or are working in the embedded space) then this might be an interesting hobby project to look info ***

HardenedBSD announces ASLR completion

• HardenedBSD, now officially a full-on fork of FreeBSD, has declared their ASLR patchset to be complete
• The latest and last addition to the work was VDSO (Virtual Dynamic Shared Object) randomization, which is now configurable with a sysctl
• This post gives a summary of the six main features they've added since the beginning
• Only a few small things are left to do - man page cleanups, possibly shared object load order improvements ***

Unlock the reaper

• In the ongoing quest to make more of OpenBSD SMP-friendly, a new patch was posted that unlocks the reaper in the kernel
• When there's a zombie process causing a resource leak, it's the reaper's job to deallocate their resources (and yes we're still talking about computers, not horror movies)
• Initial testing has yielded positive results and no regressions
• They're looking for testers, so you can install a -current snapshot and get it automatically
• An updated version of the patch is coming soon too
• A hackathon is going on right now, so you can expect more SMP improvements in the near future ***

The importance of mentoring

• Adrian Chadd has a blog post up about mentoring new users, and it tells the story of how he originally got into FreeBSD
• He tells the story of, at age 11, meeting someone else who knew about making crystal sets that became his role model
• Eventually we get to his first FreeBSD 1.1 installation (which he temporarily abandoned for Linux, since it didn't have a color "ls" command) and how he started using the OS
• Nowadays, there's a formal mentoring system in FreeBSD
• While he talks about FreeBSD in the post, a lot of the concepts apply to all the BSDs (or even just life in general) ***

OpenBSD automatic installation

• A CFT (call for testing) was posted for OpenBSD's new automatic installer process
• Using this new system, you can spin up fully-configured OpenBSD installs very quickly
• It will answer all the questions for you and can put files into place and start services
• Great for large deployments, help test it and report your findings ***

FreeNAS install guide and blog posts

• A multipart series on YouTube about installing FreeNAS
• In part 1, the guy (who is possibly Dracula, with his very Transylvanian accent..) builds his new file server and shows off the hardware
• In part 2, he shows how to install and configure FreeNAS, uses IPMI, sets up his pools
• He pronounces gigabytes as jiggabytes and it's hilarious
• We've also got an unrelated blog post about a very satisfied FreeNAS user who details his setup
• As well as another blog post from our old pal Devin Teske about his recent foray into the FreeNAS development world ***

FreeBSD 10.0-RC5 is out

• Another, unexpected RC is out for 10.0
• Minor fixes included, please help test and report any bugs
• You can update via freebsd-update or from source
• Hopefully this will be the last one before 10.0-RELEASE, which has tons of new features we'll talk about
• It's been tagged -RELEASE in SVN already too! ***

OpenBSD 5.5-beta is out

• Theo updated the branch status to 5.5-beta
• A list of changes
• Help test and report any bugs you find
• Lots of rapid development with signify (which we mentioned last week), the beta includes some "test keys"
• Does that mean it'll be part of the final release? We'll find out in May.. or when we interview Ted (soon) ***

Hostname canonicalisation in OpenSSH

• Blog post from our friend Damien Miller
• This new feature allows clients to canonicalize unqualified domain names
• SSH will know if you typed "ssh bsdnow" you meant "ssh bsdnow.tv" with new config options
• This will help clean up some ssh configs, especially if you have many hosts
• Should make it into OpenSSH 6.5, which is "due really soon" ***

Dragonfly on a Chromebook

• Some work has been done by Matthew Dillon to get DragonflyBSD working on a Google Chromebook
• These couple of posts detail some of the things he's got working so far
• Changes were needed to the boot process, trackpad and wifi drivers needed updating...
• Also includes a guide written by Dillon on how to get yours working ***

Spider in a box

• "Spiderinabox" is a new OpenBSD-based project
• Using a combination of OpenBSD, Firefox, XQuartz and VirtualBox, it creates a secure browsing experience for OS X
• Firefox runs encapsulated in OpenBSD and doesn't have access to OS X in any way
• The developer is looking for testers on other operating systems! ***

PCBSD weekly digest

• PCBSD 10 has entered into the code freeze phase
• They're focusing on fixing bugs now, rather than adding new features
• The update system got a lot of improvements
• PBI load times reduced by up to 40%! what!!! ***
