FreeBSD Jails – Deep Dive into the Beginning of FreeBSD Containers

In recent years, containers and virtualization have become a buzzword in the Linux community, especially with the rise of Docker and Kubernetes. What many people probably don’t realize is that these ideas have been around for a very long time. Today, we will be looking at Jails and how they became part of FreeBSD.

FreeBSD Jobs

• The FreeBSD Foundation is looking for a Senior Arm Kernel Engineer
• The FreeBSD Foundation is also looking for an Open Source Project Coordinator. *** ### helloSystem Releases New ISOs For This macOS-Inspired BSD Desktop OS > The helloSystem motto is being a "desktop system for creators with focus on simplicity, elegance, and usability. Based on FreeBSD. Less, but better!" The desktop utilities are written with PyQt5. *** ### A Trip into FreeBSD > I normally deal with Linux machines. Linux is what I know and it's what I've been using since I was in college. A friend of mine has been coaxing me into trying out FreeBSD, and I decided to try it out and see what it's like. Here's some details about my experience and what I've learned. *** ###Tarsnap

NetBSD on a Cobalt Qube 2

• The Cobalt Qube was a very expensive networking appliance around 2000
• In 2014, you can apparently get one of these MIPS-based machines for about forty bucks
• This blog post details getting NetBSD installed and set up on the rare relic of our networking past
• If you're an old-time fan of RISC or MIPS CPUs, this'll be a treat for you
• Lots of great pictures of the hardware too ***

OpenBSD vs. AFL

• In their never-ending security audit, some OpenBSD developers have been hitting various parts of the tree with a fuzzer
• If you're not familiar, fuzzing is a semi-automated way to test programs for crashes and potential security problems
• The program being subjected to torture gets all sorts of random and invalid input, in the hopes of uncovering overflows and other bugs
• American Fuzzy Lop, in particular, has provided some interesting results across various open source projects recently
• So far, it's fixed some NULL pointer dereferences in OpenSSH, various crashes in tcpdump and mandoc and a few other things
• AFL has an impressive list of CVEs (vulnerabilities) that it's helped developers discover and fix
• It also made its way into OpenBSD ports, FreeBSD ports and NetBSD's pkgsrc very recently, so you can try it out for yourself ***

GNOME 3 hits the FreeBSD ports tree

• While you've been able to run GNOME 3 on PC-BSD and OpenBSD for a while, it hasn't actually hit the FreeBSD ports tree.. until now
• Now you can play with GNOME 3 and all its goodies (as well as Cinnamon 2.2, which this also brings in) on vanilla FreeBSD
• Be sure to check the commit message and /usr/ports/UPDATING if you're upgrading from GNOME 2
• You might also want to go back and listen to our interview with Joe Marcus Clark about GNOME's portability ***

News Roundup

DragonFlyBSD 4.0 released

• A new major version of DragonFly, 4.0.1, was just recently announced
• This version includes support for Haswell GPUs, lots of SMP improvements (including some in PF) and support for up to 256 CPUs
• It's also the first release to drop support for i386, so it joins PCBSD in the 64 bit-only club
• Check the release notes for all the details, including networking and kernel improvements, as well as some crypto changes ***

Can we talk about FreeBSD vs Linux

• Hackernews had a recent thread about discussing Linux vs BSD, and the trolls stayed away for once
• Rather than rehashing why one is "better" than the other, it was focused on explaining some of the differences between ecosystems and communities
• If you're one of the many people who watch our show just out of curiosity about the BSD world, this might be a good thread to read
• Someone in the comments even gave bsdnow.tv a mention as a good resource to learn, thanks guy ***

OpenBSD IPSEC tunnel guide

• If you've ever wanted to connect two networks with OpenBSD gateways, this is the article for you
• It shows how to set up an IPSEC tunnel between destinations, how to lock it down and how to access all the machines on the other network just like they were on your LAN
• The article also explains some of the basics of IPSEC if you're not familiar with all the terminology, so this isn't just for experts
• Though the article itself is a few years old, it mostly still applies to the latest stuff today
• All the tools used are in the OpenBSD base system, so that's pretty handy too ***

DragonFly starts work on IPFW2

• DragonFlyBSD, much like FreeBSD, comes with more than one firewall you can use
• Now it looks like you're going to have yet another choice, as someone is working on a fork of IPFW (which is actually already in its second version, so it should be "IPFW3")
• Not a whole lot is known yet; it's still in heavy development, but there's a brief roadmap page with some planned additions
• The guy who's working on this has already agreed to come on the show for an interview, but we're going to give him a chance to get some more work done first
• Expect that sometime next year, once he's made some progress ***
