bhyve for Calamares Development

bhyve (pronounced “bee hive”) is a hypervisor for BSD systems (and Illumos / openSolaris). It is geared towards server workloads, but does support desktop-oriented operation as well. I spent some time wayyyy back in November wrestling with it in order to replace VirtualBox for Calamares testing on FreeBSD. The “golden hint” as far as I’m concerned came from Karen Bruner and now I have a functioning Calamares test-ground that is more useful than before.
“Calamares is a free and open-source independent and distro-agnostic system installer for Linux distributions.“

New Release: Only Footnotes
I’ve lost count of the number of people who have told me that they purchase my books only for the footnotes. That’s okay. I don’t care why people buy my books, only that they do buy them. Nevertheless, I am a businessman living under capitalism and feel compelled to respond to my market.
Allow me to present my latest release: Only Footnotes, a handsome hardcover-only compilation of decades of footnotes. From the back cover:
-----
Only Footnotes. Because that’s why you read his books.
Academics hate footnotes. Michael W Lucas loves them. What he does with them wouldn’t pass academic muster, but that doesn’t mean the reader should skip them. The footnotes are the best part! Why not read only the footnotes, and skip all that other junk?
After literal minutes of effort, Only Footnotes collects every single footnote from all of Lucas’ books to date.* Recycle those cumbersome treatises stuffed with irrelevant facts! No more flipping through pages and pages of actual technical knowledge looking for the offhand movie reference or half-formed joke. This slender, elegant volume contains everything the man ever passed off as his dubious, malformed “wisdom.”
Smart books have footnotes. Smarter books are only footnotes.
*plus additional annotations from the author. Because sometimes even a footnote needs a footnote.
----
With interior illustrations by OpenBSD’s akoshibe, this distinguished tome would make fine inspirational reading for a system administrator, network engineer, or anyone sentenced to a life in information technology. Available at all fine bookstores, and many mediocre ones!

Setup a Three Node Replicated GlusterFS Cluster on FreeBSD

GlusterFS (GFS) is the open source equivalent to Microsoft's Distributed Filesystem (DFS). It's a service that replicates the contents of a filesystem in real time from one server to another. Clients connect to any server and changes made to a file will replicate automatically. It's similar to something like rsync or syncthing, but much more automatic and transparent. A FreeBSD port has been available since v3.4, and (as of this post) is currently at version 8.0 with 9.0 being released soon.

After our AMA episode where I mentioned I was looking for older BSD Retail Copies, I was contacted by Andrew who hooked me up with a bunch of OpenBSD disks from the 4.x era. So shout out to him, and since that worked so well, I figured I'd give it another shot and ask that if anyone has any old Unixes that will run on an 8088, 8086, or 286 and you're willing to send me copies of the disks. I've recently dug out an old 286 system and I’d love to get a Unix OS on it. I know of Minix, Xenix and Microport, but I haven’t been able to find many versions of them. I've found Microport 1.3.3, and SCO Xenix... but that's about it. Let me know if you happen to have any other versions, or know where I can get them.

This helped recapture some of the “hallway track” that would be lost in an online conference.

BastilleBSD - native container management for FreeBSD

Some time ago, I had the requirement to use FreeBSD in a project, and soon the question came up if Docker and Kubernetes can be used.
On FreeBSD, Docker is not very well supported, and even if you can get it running, Linux is used in a Docker container. My experience with Docker on FreeBSD is awful, and so I started looking for alternatives.
A quick search on one of the most significant online search engines led me to Jails and then to BastilleBSD.

Tarsnap – cleaning up old backups

I use Tarsnap for my critical data. Case in point, I use it to backup my Bacula database dump. I use Bacula to backup my hosts. The database in question keeps track of what was backed up, from what host, the file size, checksum, where that backup is now, and many other items. Losing this data is annoying but not a disaster. It can be recreated from the backup volumes, but that is time consuming. As it is, the file is dumped daily, and rsynced to multiple locations.

MWL - BookSale

For those interested in such things, I recently posted my 60,000th tweet. This prodded me to try an experiment I’ve been pondering for a while.
Over at my ebookstore, two of my books are now on a “Name Your Own Price” sale. You can get git commit murder and PAM Mastery for any price you wish, with a minimum of $1.

OpenBSD vs FreeBSD security features

• From the author of both the OpenBSD and FreeBSD secure gateway articles we've featured in the past comes a new entry about security
• The article goes through a list of all the security features enabled (and disabled) by default in both FreeBSD and OpenBSD
• It covers a wide range of topics, including: memory protection, randomization, encryption, privilege separation, Capsicum, securelevels, MAC, Jails and chroots, network stack hardening, firewall features and much more
• This is definitely one of the most in-depth and complete articles we've seen in a while - the author seems to have done his homework
• If you're looking to secure any sort of BSD box, this post has some very detailed explanations of different exploit mitigation techniques - be sure to read the whole thing
• There are also some good comments on DaemonForums and lobste.rs that you may want to read ***

The password? You changed it, right?

• Peter Hansteen has a new blog post up, detailing some weird SSH bruteforcing he's seen recently
• He apparently reads his auth logs when he gets bored at an airport
• This new bruteforcing attempt seems to be targetting D-Link devices, as evidenced by the three usernames the bots try to use
• More than 700 IPs have tried to get into Peter's BSD boxes using these names in combination with weak passwords
• Lots more details, including the lists of passwords and IPs, can be found in the full article
• If you're using a BSD router, things like this can be easily prevented with PF or fail2ban (and you probably don't have a "d-link" user anyway) ***

Get started with FreeBSD, an intro for Linux users

• Another new BSD article on a mainstream technology news site - seems we're getting popular
• This article is written for Linux users who may be considering switching over to BSD and wondering what it's all about
• It details installing FreeBSD 9.3 and getting a basic system setup, while touching on ports and packages, and explaining some terminology along the way
• "Among the legions of Linux users and admins, there seems to be a sort of passive curiosity about FreeBSD and other BSDs. Like commuters on a packed train, they gaze out at a less crowded, vaguely mysterious train heading in a slightly different direction and wonder what traveling on that train might be like" **

OpenSMTPD status update

• The OpenSMTPD guys, particularly Gilles, have posted an update on what they've been up to lately
• As of 5.6, it's become the default MTA in OpenBSD, and sendmail will be totally gone in 5.7
• Email is a much more tricky protocol than you might imagine, and the post goes through some of the weirdness and problems they've had to deal with
• There's also another post that goes into detail on their upcoming filtering API - a feature many have requested
• The API is still being developed, but you can test it out now if you know what you're doing - full details in the article
• OpenSMTPD also has portable versions in FreeBSD ports and NetBSD pkgsrc, so check it out ***

OpenCrypto changes in FreeBSD

• A little while back, we talked to John-Mark Gurney about updating FreeBSD's OpenCrypto framework, specifically for IPSEC
• Some of that work has just landed in the -CURRENT branch, and the commit has a bit of details
• The ICM and GCM modes of AES were added, and both include support for AESNI
• There's a new port - "nist-kat" - that can be used to test the new modes of operation
• Some things were fixed in the process as well, including an issue that would leak timing info and result in the ability to forge messages
• Code was also borrowed from both OpenBSD and NetBSD to make this possible ***

First thoughts on OpenBSD's httpd

• Here we have a blog post from a user of OpenBSD's new homegrown web server that made its debut in 5.6
• The author loves that it has proper privilege separation, a very simple config syntax and that it always runs in a chroot
• He also mentions dynamic content hosting with FastCGI, and provides an example of how to set it up
• Be sure to check our interview with Reyk about the new httpd if you're curious on how it got started
• Also, if you're running the version that came with 5.6, there's a huge patch you can apply to get a lot of the features and fixes from -current without waiting for 5.7 ***

Steam on PCBSD

• One of the most common questions people who want to use BSD as a desktop ask us is "can I run games?" or "can I use steam?"
• Steam through the Linux emulation layer (in FreeBSD) may be possible soon, but it's already possible to use it with WINE
• This video shows how to get Steam set up on PCBSD using the Windows version
• There are also some instructions in the video description to look over
• A second video details getting streaming set up ***

FreeBSD quarterly status report

• FreeBSD has gotten quite a lot done this quarter
• Changes in the way release branches are supported - major releases will get at least five years over their lifespan
• A new automounter is in the works, hoping to replace amd (which has some issues)
• The CAM target layer and RPC stack have gotten some major optimization and speed boosts
• Work on ZFSGuru continues, with a large status report specifically for that
• The report also mentioned some new committers, both source and ports
• It also covers GNATS being replaced with Bugzilla, the new core team, 9.3-RELEASE, GSoC updates, UEFI booting and lots of other things that we've already mentioned on the show
• "Foundation-sponsored work resulted in 226 commits to FreeBSD over the April to June period" ***

A new OpenBSD HTTPD is born

• Work has begun on a new HTTP daemon in the OpenBSD base system
• A lot of people are asking "why?" since OpenBSD includes a chrooted nginx already - will it be removed? Will they co-exist?
• Initial responses seem to indicate that nginx is getting bloated, and is a bit overkill for just serving content (this isn't trying to be a full-featured replacement)
• It's partially based on the relayd codebase and also comes from the author of relayd, Reyk Floeter
• This has the added benefit of the usual, easy-to-understand syntax and privilege separation
• There's a very brief man page online already
• It supports vhosts and can serve static files, but is still in very active development - there will probably be even more new features by the time this airs
• Will it be named OpenHTTPD? Or perhaps... LibreHTTPD? (I hope not) ***

pkgng 1.3 announced

• The newest version of FreeBSD's second generation package management system has been released, with lots of new features
• It has a new "real" solver to automatically handle conflicts, and dynamically discover new ones (this means the annoying -o option is deprecated now, hooray!)
• Lots of the code has been sandboxed for extra security
• You'll probably notice some new changes to the UI too, making things more user friendly
• A few days later 1.3.1 was released to fix a few small bugs, then 1.3.2 shortly thereafter and 1.3.3 yesterday ***

FreeBSD after-install security tasks

• A number of people have written in to ask us "how do I secure my BSD box after I install it?"
• With this blog post, hopefully most of their questions will finally be answered in detail
• It goes through locking down SSH with keys, patching the base system for security, installing packages and keeping them updated, monitoring and closing any listening services and a few other small things
• Not only does it just list things to do, but the post also does a good job of explaining why you should do them
• Maybe we'll see some more posts in this series in the future ***

• MWL's new book about the FreeBSD storage subsystems now has an early draft available
• Early buyers can get access to an in-progress draft of the book before the official release, but keep in mind that it may go through a lot of changes
• Topics of the book will include GEOM, UFS, ZFS, the disk utilities, partition schemes, disk encryption and maximizing I/O performance
• You'll get access to the completed (e)book when it's done if you buy the early draft
• The suggested price is $8 ***

Why BSD and not Linux?

• Yet another thread comes up asking why you should choose BSD over Linux or vice-versa
• Lots of good responses from users of the various BSDs
• Directly ripping a quote: "Features like Ports, Capsicum, CARP, ZFS and DTrace were stable on BSDs before their Linux versions, and some of those are far more usable on BSD. Features like pf are still BSD-only. FreeBSD has GELI and ipfw and is "GCC free". DragonflyBSD has HAMMER and kernel performance tuning. OpenBSD have upstream pf and their gamut of security features, as well as a general emphasis on simplicity."
• And "Over the years, the BSDs have clearly shown their worth in the nix ecosystem by pioneering new features and driving adoption of others. The most recent on OpenBSD were 2038 support and LibreSSL. FreeBSD still arguably rules the FOSS storage space with ZFS."
• Some other users share their switching experiences - worth a read ***

More g2k14 hackathon reports

• Following up from last week's huge list of hackathon reports, we have a few more
• Landry Breuil spent some time with Ansible testing his infrastructure, worked on the firefox port and tried to push some of their patches upstream
• Andrew Fresh enjoyed his first hackathon, pushing OpenBSD's perl patches upstream and got tricked into rewriting the adduser utility in perl
• Ted Unangst did his usual "teduing" (removing of) old code - say goodbye to asa, fpr, mkstr, xstr, oldrdist, fsplit, uyap and bluetooth
• Luckily we didn't have to cover 20 new ones this time! ***

BSDTalk episode 243

• The newest episode of BSDTalk is out, featuring an interview with Ingo Schwarze of the OpenBSD team
• The main topic of discussion is mandoc, which some users might not be familiar with
• mandoc is a utility for formatting manpages that OpenBSD and NetBSD use (DragonFlyBSD and FreeBSD include it in their source tree, but it's not built by default)
• We'll catch up to you soon, Will! ***
