Today on BSD Now, the latest Dragonfly BSD release, RaidZ performance, another OpenSSL Vulnerability, and more; all this week on BSD Now. This episode was brought to you by Headlines DragonFly BSD 4.8 is released (https://www.dragonflybsd.org/release48/) Improved kernel performance This release further localizes cache lines and reduces/removes cache ping-ponging on globals. For bulk builds on many-cores or multi-socket systems, we have around a 5% improvement, and certain subsystems such as namecache lookups and exec()s see massive focused improvements. See the corresponding mailing list post with details. Support for eMMC booting, and mobile and high-performance PCIe SSDs This kernel release includes support for eMMC storage as the boot device. We also sport a brand new SMP-friendly, high-performance NVMe SSD driver (PCIe SSD storage). Initial device test results are available. EFI support The installer can now create an EFI or legacy installation. Numerous adjustments have been made to userland utilities and the kernel to support EFI as a mainstream boot environment. The /boot filesystem may now be placed either in its own GPT slice, or in a DragonFly disklabel inside a GPT slice. DragonFly, by default, creates a GPT slice for all of DragonFly and places a DragonFly disklabel inside it with all the standard DFly partitions, such that the disk names are roughly the same as they would be in a legacy system. Improved graphics support The i915 driver has been updated to match the version found with the Linux 4.6 kernel. Broadwell and Skylake processor users will see improvements. Other user-affecting changes Kernel is now built using -O2. VKernels now use COW, so multiple vkernels can share one disk image. powerd() is now sensitive to time and temperature changes. Non-boot-filesystem kernel modules can be loaded in rc.conf instead of loader.conf. *** #8005 poor performance of 1MB writes on certain RAID-Z configurations (https://github.com/openzfs/openzfs/pull/321) Matt Ahrens posts a new patch for OpenZFS Background: RAID-Z requires that space be allocated in multiples of P+1 sectors,because this is the minimum size block that can have the required amount of parity. Thus blocks on RAIDZ1 must be allocated in a multiple of 2 sectors; on RAIDZ2 multiple of 3; and on RAIDZ3 multiple of 4. A sector is a unit of 2^ashift bytes, typically 512B or 4KB. To satisfy this constraint, the allocation size is rounded up to the proper multiple, resulting in up to 3 "pad sectors" at the end of some blocks. The contents of these pad sectors are not used, so we do not need to read or write these sectors. However, some storage hardware performs much worse (around 1/2 as fast) on mostly-contiguous writes when there are small gaps of non-overwritten data between the writes. Therefore, ZFS creates "optional" zio's when writing RAID-Z blocks that include pad sectors. If writing a pad sector will fill the gap between two (required) writes, we will issue the optional zio, thus doubling performance. The gap-filling performance improvement was introduced in July 2009. Writing the optional zio is done by the io aggregation code in vdevqueue.c. The problem is that it is also subject to the limit on the size of aggregate writes, zfsvdevaggregationlimit, which is by default 128KB. For a given block, if the amount of data plus padding written to a leaf device exceeds zfsvdevaggregation_limit, the optional zio will not be written, resulting in a ~2x performance degradation. The solution is to aggregate optional zio's regardless of the aggregation size limit. As you can see from the graphs, this can make a large difference in performance. I encourage you to read the entire commit message, it is well written and very detailed. *** Can you spot the OpenSSL vulnerability (https://guidovranken.wordpress.com/2017/01/28/can-you-spot-the-vulnerability/) This code was introduced in OpenSSL 1.1.0d, which was released a couple of days ago. This is in the server SSL code, ssl/statem/statemsrvr.c, sslbytestocipherlist()), and can easily be reached remotely. Can you spot the vulnerability? So there is a loop, and within that loop we have an ‘if' statement, that tests a number of conditions. If any of those conditions fail, OPENSSLfree(raw) is called. But raw isn't the address that was allocated; raw is increment every loop. Hence, there is a remote invalid free vulnerability. But not quite. None of those checks in the ‘if' statement can actually fail; earlier on in the function, there is a check that verifies that the packet contains at least 1 byte, so PACKETget1 cannot fail. Furthermore, earlier in the function it is verified that the packet length is a multiple of 3, hence PACKETcopybytes and PACKET_forward cannot fail. So, does the code do what the original author thought, or expected it to do? But what about the next person that modifies that code, maybe changing or removing one of the earlier checks, allowing one of those if conditions to fail, and execute the bad code? Nonetheless OpenSSL has acknowledged that the OPENSSL_free line needs a rewrite: Pull Request #2312 (https://github.com/openssl/openssl/pull/2312) PS I'm not posting this to ridicule the OpenSSL project or their programming skills. I just like reading code and finding corner cases that impact security, which is an effort that ultimately works in everybody's best interest, and I like to share what I find. Programming is a very difficult enterprise and everybody makes mistakes. Thanks to Guido Vranken for the sharp eye and the blog post *** Research Debt (http://distill.pub/2017/research-debt/) I found this article interesting as it relates to not just research, but a lot of technical areas in general Achieving a research-level understanding of most topics is like climbing a mountain. Aspiring researchers must struggle to understand vast bodies of work that came before them, to learn techniques, and to gain intuition. Upon reaching the top, the new researcher begins doing novel work, throwing new stones onto the top of the mountain and making it a little taller for whoever comes next. People expect the climb to be hard. It reflects the tremendous progress and cumulative effort that's gone into the research. The climb is seen as an intellectual pilgrimage, the labor a rite of passage. But the climb could be massively easier. It's entirely possible to build paths and staircases into these mountains. The climb isn't something to be proud of. The climb isn't progress: the climb is a mountain of debt. Programmers talk about technical debt: there are ways to write software that are faster in the short run but problematic in the long run. Poor Exposition – Often, there is no good explanation of important ideas and one has to struggle to understand them. This problem is so pervasive that we take it for granted and don't appreciate how much better things could be. Undigested Ideas – Most ideas start off rough and hard to understand. They become radically easier as we polish them, developing the right analogies, language, and ways of thinking. Bad abstractions and notation – Abstractions and notation are the user interface of research, shaping how we think and communicate. Unfortunately, we often get stuck with the first formalisms to develop even when they're bad. For example, an object with extra electrons is negative, and pi is wrong Noise – Being a researcher is like standing in the middle of a construction site. Countless papers scream for your attention and there's no easy way to filter or summarize them. We think noise is the main way experts experience research debt. There's a tradeoff between the energy put into explaining an idea, and the energy needed to understand it. On one extreme, the explainer can painstakingly craft a beautiful explanation, leading their audience to understanding without even realizing it could have been difficult. On the other extreme, the explainer can do the absolute minimum and abandon their audience to struggle. This energy is called interpretive labor Research distillation is the opposite of research debt. It can be incredibly satisfying, combining deep scientific understanding, empathy, and design to do justice to our research and lay bare beautiful insights. Distillation is also hard. It's tempting to think of explaining an idea as just putting a layer of polish on it, but good explanations often involve transforming the idea. This kind of refinement of an idea can take just as much effort and deep understanding as the initial discovery. + The distillation can often times require an entirely different set of skills than the original creation of the idea. Almost all of the BSD projects have some great ideas or subsystems that just need distillation into easy to understand and use platforms or tools. Like the theoretician, the experimentalist or the research engineer, the research distiller is an integral role for a healthy research community. Right now, almost no one is filling it. Anyway, if that bit piqued your interest, go read the full article and the suggested further reading. *** News Roundup And then the murders began. (https://blather.michaelwlucas.com/archives/2902) A whole bunch of people have pointed me at articles like this one (http://thehookmag.com/2017/03/adding-murders-began-second-sentence-book-makes-instantly-better-125462/), which claim that you can improve almost any book by making the second sentence “And then the murders began.” It's entirely possible they're correct. But let's check, with a sampling of books. As different books come in different tenses and have different voices, I've made some minor changes. “Welcome to Cisco Routers for the Desperate! And then the murders begin.” — Cisco Routers for the Desperate, 2nd ed “Over the last ten years, OpenSSH has become the standard tool for remote management of Unix-like systems and many network devices. And then the murders began.” — SSH Mastery “The Z File System, or ZFS, is a complicated beast, but it is also the most powerful tool in a sysadmin's Batman-esque utility belt. And then the murders begin.” — FreeBSD Mastery: Advanced ZFS “Blood shall rain from the sky, and great shall be the lamentation of the Linux fans. And then, the murders will begin.” — Absolute FreeBSD, 3rd Ed Netdata now supports FreeBSD (https://github.com/firehol/netdata) netdata is a system for distributed real-time performance and health monitoring. It provides unparalleled insights, in real-time, of everything happening on the system it runs (including applications such as web and database servers), using modern interactive web dashboards. From the release notes: apps.plugin ported for FreeBSD Check out their demo sites (https://github.com/firehol/netdata/wiki) *** Distrowatch Weekly reviews RaspBSD (https://distrowatch.com/weekly.php?issue=20170220#raspbsd) RaspBSD is a FreeBSD-based project which strives to create a custom build of FreeBSD for single board and hobbyist computers. RaspBSD takes a recent snapshot of FreeBSD and adds on additional components, such as the LXDE desktop and a few graphical applications. The RaspBSD project currently has live images for Raspberry Pi devices, the Banana Pi, Pine64 and BeagleBone Black & Green computers. The default RaspBSD system is quite minimal, running a mere 16 processes when I was logged in. In the background the operating system runs cron, OpenSSH, syslog and the powerd power management service. Other than the user's shell and terminals, nothing else is running. This means RaspBSD uses little memory, requiring just 16MB of active memory and 31MB of wired or kernel memory. I made note of a few practical differences between running RaspBSD on the Pi verses my usual Raspbian operating system. One minor difference is RaspBSD turns off the Pi's external power light after booting. Raspbian leaves the light on. This means it looks like the Pi is off when it is running RaspBSD, but it also saves a little electricity. Conclusions: Apart from these little differences, running RaspBSD on the Pi was a very similar experience to running Raspbian and my time with the operating system was pleasantly trouble-free. Long-term, I think applying source updates to the base system might be tedious and SD disk operations were slow. However, the Pi usually is not utilized for its speed, but rather its low cost and low-energy usage. For people who are looking for a small home server or very minimal desktop box, RaspBSD running on the Pi should be suitable.

This week, we'll be talking to Henning Brauer about OpenNTPD and its recently revived portable version. After that, we'll be discussing different ways to securely tunnel your traffic: specifically OpenVPN, IPSEC, SSH and Tor. All that and the latest news, coming up on BSD Now - the place to B.. SD. This episode was brought to you by Headlines Strange timer bug in FreeBSD 11 (https://lists.freebsd.org/pipermail/freebsd-current/2015-February/054295.html) Peter Wemm (http://www.bsdnow.tv/episodes/2014_09_24-beastly_infrastructure) wrote in to the FreeBSD -CURRENT mailing list with an interesting observation Running the latest development code in the infrastructure, the clock would stop keeping time after 24 days of uptime This meant things like cron and sleep would break, TCP/IP wouldn't time out or resend packets, a lot of things would break A workaround until it was fixed was to reboot every 24 days, but this is BSD we're talking about - uptime is our game An initial proposal was adding a CFLAG to the build options which makes makes signed arithmetic wrap Peter disagreed and gave some background (https://lists.freebsd.org/pipermail/freebsd-current/2015-February/054320.html), offering a different patch to fix (https://lists.freebsd.org/pipermail/svn-src-head/2015-February/067827.html) the issue and detect it early (https://lists.freebsd.org/pipermail/svn-src-head/2015-February/067828.html) if it happens again Ultimately, the problem was traced back to an issue with a recent clang import It only affected -CURRENT, not -RELEASE or -STABLE, but was definitely a bizarre bug to track down *** An OpenBSD mail server (http://technoquarter.blogspot.com/p/series.html) There's been a recent influx of blog posts about building a BSD mail server for some reason In this fancy series of posts, the author sets up OpenSMTPD in its native OpenBSD home, whereas previous posts have been aimed at FreeBSD and Linux In addition to the usual steps, this one also covers DKIMproxy, ClamAV for scanning attachments, Dovecot for IMAP and also multiple choices of spam filtering: spamd or SpamAssassin It also shows you how to set up Roundcube for building a web interface, using the new in-base httpd That means this is more of a "complete solution" - right down to what the end users see The series is split up into categories so it's very easy to follow along step-by-step *** How DragonFlyBSD uses git (http://lists.dragonflybsd.org/pipermail/users/2015-January/207421.html) DragonFlyBSD, along with PCBSD and EdgeBSD, uses git as its version control system for the system source code In a series (http://lists.dragonflybsd.org/pipermail/users/2015-January/207422.html) of posts (http://lists.dragonflybsd.org/pipermail/users/2015-January/207424.html), Matthew Dillon (the project lead) details their internal setup They're using vanilla git over ssh, with the developers' accounts set to git-only (no shell access) The maintainers of the server are the only ones with shell access available He also details how a cron job syncs from the master to a public box that anyone can check out code from It would be interesting to hear about how other BSD projects manage their master source repository *** Why not try PCBSD? (http://www.itwire.com/business-it-news/open-source/66900-fed-up-with-systemd-and-linux?-why-not-try-pc-bsd) ITwire, another more mainstream tech site, published a recent article about switching to PCBSD They interview a guy named Kris that we've never heard of before In the article, they touch on how easy it can potentially be for Linux users looking to switch over to the BSD side - lots of applications are exactly the same "With the growing adoption of systemd, dissatisfaction with Linux has reached proportions not seen in recent years, to the extent that people have started talking of switching to FreeBSD." If you have some friends who complain to you about systemd all the time, this might be a good article to show them *** Interview - Henning Brauer - henning@openbsd.org (mailto:henning@openbsd.org) / @henningbrauer (https://twitter.com/henningbrauer) OpenNTPD (http://openntpd.org/) and its portable variant News Roundup Authenticated time in OpenNTPD (https://www.marc.info/?l=openbsd-tech&m=142356166731390&w=2) We recorded that interview with Henning just a few days ago, and it looks like part of it may be outdated already While at the hackathon, some developers came up with an alternate way (https://www.marc.info/?l=openbsd-cvs&m=142355043928397&w=2) to get authenticated NTP responses You can now add an HTTPS URL to your ntpd.conf in addition to the time server pool OpenNTPD will query it (over TLS, with CA verification) and look at the date sent in the HTTPS header It's not intended to be a direct time source, just a constraint to keep things within reason If you receive regular NTP packets that are way off from the TLS packet, those will be discarded and the server(s) marked as invalid Henning (https://www.marc.info/?l=openbsd-tech&m=142363215730069&w=2) and Theo (https://www.marc.info/?l=openbsd-tech&m=142363400330522&w=2) also weigh in to give some of the backstory on the idea Lots more detail can be found in Reyk's email explaining the new feature (and it's optional of course) *** NetBSD at Open Source Conference 2015 Oita and Hamanako (https://mail-index.netbsd.org/netbsd-advocacy/2015/02/08/msg000678.html) It's been a while since we've featured one of these trip reports, but the Japanese NetBSD users group is still doing them This time the conferences were in Oita and Hamanako (https://mail-index.netbsd.org/netbsd-advocacy/2015/02/11/msg000679.html), Japan Machines running NetBSD included the CubieBoard2 Allwinner A20, Raspberry Pi and Banana Pi, Sharp NetWalker and a couple Zaurus devices As always, they took lots of pictures from the event of NetBSD on all these weird machines *** Poudriere in a jail (http://www.tobeannounced.org/2015/02/poudriere-in-a-jail/) A common question we get about our poudriere tutorial (http://www.bsdnow.tv/tutorials/poudriere) is "how do I run it in a jail?" - this blog post is about exactly that It takes you through the networking setup, zpool setup, nginx setup, making the jail and finally poking the right holes in the jail to allow poudriere to work its magic *** Bruteblock, another way to stop bruteforce (http://easyos.net/articles/bsd/freebsd/bruteblock_protection_against_bruteforce_attacks_in_ssh) We've mentioned a few different ways to stop ssh bruteforce attempts in the past: fail2ban, denyhosts, or even just with pf's built-in rate limiting Bruteblock is a similar tool, but it's not just for ssh logins - it can do a number of other services It can also work directly with IPFW, which is a plus if you're using that as your firewall Add a few lines to your syslog.conf and bruteblock will get executed automatically The rest of the article takes you through the different settings you can configure for blocking *** New iwm(4) driver and cross-polination (https://www.marc.info/?l=openbsd-cvs&m=142325218626853&w=2) The OpenBSD guys recently imported a new "iwm" driver for newer Intel 7260 wireless cards (commonly found in Thinkpads) NetBSD wasted no time in porting it over (https://mail-index.netbsd.org/source-changes/2015/02/07/msg062979.html), giving a bit of interesting backstory According to Antti Kantee (http://www.bsdnow.tv/episodes/2013_10_23-a_brief_intorduction), "it was created for OpenBSD by writing and porting a NetBSD driver which was developed in a rump kernel in Linux userspace" Both projects would appreciate further testing if you have the hardware and can provide useful bug reports Maybe FreeBSD and DragonFly will port it over too, or come up with something that's partially based on the code *** PCBSD current images (http://blog.pcbsd.org/2015/02/pc-bsd-11-0-current-images-now-available/) The first PCBSD -CURRENT images should be available this weekend This image will be tagged 11.0-CURRENTFEB2015, with planned monthly updates For the more adventurous this will allow testing both FreeBSD and PCBSD bleeding edge *** Feedback/Questions Antonio writes in (http://slexy.org/view/s2E4NbJwzs) Richard writes in (http://slexy.org/view/s2FkxcSYKy) Charlie writes in (http://slexy.org/view/s217EgA1JC) Ben writes in (http://slexy.org/view/s21vlCbGDt) *** Mailing List Gold A systematic effort (https://lists.gnu.org/archive/html/emacs-devel/2015-02/msg00360.html) GCC's lunch (https://lists.gnu.org/archive/html/emacs-devel/2015-02/msg00457.html) Hopes and dreams (https://marc.info/?l=openbsd-cvs&m=142331891908776&w=2) *** Discussion Comparison of ways to securely tunnel your traffic OpenVPN (https://openvpn.net/index.php/open-source.html), OpenBSD IKED (http://www.openiked.org/), FreeBSD IPSEC (https://www.freebsd.org/doc/handbook/ipsec.html), OpenSSH (http://www.openssh.com/), Tor (https://www.torproject.org/) ***

This week on the show, we'll be starting a two-part series detailing the activities of various BSD foundations. Ed Maste from the FreeBSD foundation will be joining us this time, and we'll talk about what all they've been up to lately. All this week's news and answers to viewer-submitted questions, coming up on BSD Now - the place to B.. SD. This episode was brought to you by Headlines Key rotation in OpenSSH 6.8 (http://blog.djm.net.au/2015/02/key-rotation-in-openssh-68.html) Damien Miller (http://www.bsdnow.tv/episodes/2013_12_18-cryptocrystalline) posted a new blog entry about one of the features in the upcoming OpenSSH 6.8 Times changes, key types change, problems are found with old algorithms and we switch to new ones In OpenSSH (and the SSH protocol) however, there hasn't been an easy way to rotate host keys... until now With this change, when you connect to a server, it will log all the server's public keys in your known_hosts file, instead of just the first one used during the key exchange Keys that are in your known_hosts file but not on the server will get automatically removed This fixes the problem of old servers still authenticating with ancient DSA or small RSA keys, as well as providing a way for the server to rotate keys every so often There are some instructions in the blog post for how you'll be able to rotate host keys and eventually phase out the older ones - it's really simple There are a lot of big changes coming in OpenSSH 6.8, so we'll be sure to cover them all when it's released *** NetBSD Banana Pi images (https://mail-index.netbsd.org/port-arm/2015/01/30/msg002809.html) We've talked about the Banana Pi (http://www.bananapi.org/p/product.html) a bit before - it's a small ARM board that's comparable to the popular Raspberry Pi Some NetBSD -current images were posted on the mailing list, so now you can get some BSD action on one of these little devices There are even a set of prebuilt pkgsrc packages, so you won't have to compile everything initially The email includes some steps to get everything working and an overview of what comes with the image Also check the wiki page (https://wiki.netbsd.org/ports/evbarm/allwinner/) for some related boards and further instructions on getting set up On a related note, NetBSD also recently got GPU acceleration working (https://blog.netbsd.org/tnf/entry/raspberry_pi_gpu_acceleration_in) for the Raspberry Pi (which is a first for their ARM port) *** LibreSSL shirts and other BSD goodies (https://www.marc.info/?l=openbsd-misc&m=142255048510669&w=2) If you've been keeping up with the LibreSSL saga and want a shirt to show your support, they're finally available to buy online There are two versions, either "keep calm and use LibreSSL (https://shop.openbsdeurope.com/images/shop_openbsdeurope_com/products/large/TSHIRTLSSL.jpg)" or the slightly more snarky "keep calm and abandon OpenSSL (https://shop.openbsdeurope.com/images/shop_openbsdeurope_com/products/large/TSHIRTOSSL.jpg)" While on the topic, we thought it would be good to make people aware of shirts for other BSD projects too You can get some FreeBSD, PCBSD (https://www.freebsdmall.com/cgi-bin/fm/scan/fi=prod_bsd/se=pc-bsd) and FreeNAS stuff (https://www.freebsdmall.com/cgi-bin/fm/scan/fi=prod_bsd/se=shirts) from the FreeBSD mall site (https://www.freebsdmall.com/cgi-bin/fm/scan/fi=prod_bsd/se=tshirt) OpenBSD recently launched their new store (https://www.openbsdstore.com), but the selection is still a bit limited right now NetBSD has a couple places (https://www.netbsd.org/gallery/devotionalia.html#cafepress) where you can buy shirts and other apparel with the flag logo on it We couldn't find any DragonFlyBSD shirts unfortunately, which is a shame since their logo (http://www.dragonflybsd.org/images/small_logo.png) is pretty cool Profits from the sale of the gear go back to the projects, so pick up some swag and support your BSD of choice (and of course wear them at any Linux events you happen to go to) *** OPNsense 15.1.4 released (https://forum.opnsense.org/index.php?topic=35.0) The OPNsense guys have been hard at work since we spoke to them (http://www.bsdnow.tv/episodes/2015_01_14-common_sense_approach), fixing lots of bugs and keeping everything up to date A number of versions have come out since then, with 15.1.4 being the latest (assuming they haven't updated it again by the time this airs) This version includes the latest round of FreeBSD kernel security patches, as well as minor SSL and GUI fixes They're doing a great job of getting upstream fixes pushed out to users quickly, a very welcome change A developer has also posted an interesting write-up titled "Development Workflow in OPNsense (http://lastsummer.de/development-workflow-in-opnsense/)" If any of our listeners are trying OPNsense as their gateway firewall, let us know how you like it *** Interview - Ed Maste - board@freebsdfoundation.org (mailto:board@freebsdfoundation.org) The FreeBSD foundation (https://www.freebsdfoundation.org/donate)'s activities News Roundup Rolling with OpenBSD snapshots (http://homing-on-code.blogspot.com/2015/02/rolling-with-snapshots.html) One of the cool things about the -current branch of OpenBSD is that it doesn't require any compiling There are signed binary snapshots being continuously re-rolled and posted on the FTP sites for every architecture This provides an easy method to get onboard with the latest features, and you can also easily upgrade between them without reformatting or rebuilding This blog post will walk you through the process of using snapshots to stay on the bleeding edge of OpenBSD goodness After using -current for seven weeks, the author comes to the conclusion that it's not as unstable as people might think He's now helping test out patches and new ports since he's running the same code as the developers *** Signing pkgsrc packages (https://mail-index.netbsd.org/tech-pkg/2015/02/02/msg014224.html) As of the time this show airs, the official pkgsrc (http://www.bsdnow.tv/tutorials/pkgsrc) packages aren't cryptographically signed Someone from Joyent has been working on that, since they'd like to sign their pkgsrc packages for SmartOS Using GNUPG pulled in a lot of dependencies, and they're trying to keep the bootstrapping process minimal Instead, they're using netpgpverify, a fork of NetBSD's netpgp (https://en.wikipedia.org/wiki/Netpgp) utility Maybe someday this will become the official way to sign packages in NetBSD? *** FreeBSD support model changes (https://lists.freebsd.org/pipermail/freebsd-announce/2015-February/001624.html) Starting with 11.0-RELEASE, which won't be for a few months probably, FreeBSD releases are going to have a different support model The plan is to move "from a point release-based support model to a set of releases from a branch with a guaranteed support lifetime" There will now be a five-year lifespan for each major release, regardless of how many minor point releases it gets This new model should reduce the turnaround time for errata and security patches, since there will be a lot less work involved to build and verify them Lots more detail can be found in the mailing list post, including some important changes to the -STABLE branch, so give it a read *** OpenSMTPD, Dovecot and SpamAssassin (http://guillaumevincent.com/2015/01/31/OpenSMTPD-Dovecot-SpamAssassin.html) We've been talking about setting up your own BSD-based mail server on the last couple episodes Here we have another post from a user setting up OpenSMTPD, including Dovecot for IMAP and SpamAssassin for spam filtering A lot of people regularly ask the developers (http://permalink.gmane.org/gmane.mail.opensmtpd.general/2265) how to combine OpenSMTPD with spam filtering, and this post should finally reveal the dark secrets In addition, it also covers SSL certificates, PKI and setting up MX records - some things that previous posts have lacked Just be sure to replace those "apt-get" commands and "eth0" interface names with something a bit more sane… In related news, OpenSMTPD has got some interesting new features coming soon (http://article.gmane.org/gmane.mail.opensmtpd.general/2272) They're also planning to switch to LibreSSL by default (https://github.com/OpenSMTPD/OpenSMTPD/issues/534) for the portable version *** FreeBSD 10 on the Thinkpad T400 (http://lastsummer.de/freebsd-desktop-on-the-t400/) BSD laptop articles are becoming popular it seems - this one is about FreeBSD on a T400 Like most of the ones we've mentioned before, it shows you how to get a BSD desktop set up with all the little tweaks you might not think to do This one differs in that it takes a more minimal approach to graphics: instead of a full-featured environment like XFCE or KDE, it uses the i3 tiling window manager If you're a commandline junkie that basically just uses X11 to run more than one terminal at once, this might be an ideal setup for you The post also includes some bits about the DRM and KMS in the 10.x branch, as well as vt *** PC-BSD 10.1.1 Released (http://blog.pcbsd.org/2015/02/1810/) Automatic background updater now in Shiny new Qt5 utils OVA files for VM's Full disk encryption with GELI v7 *** Feedback/Questions Camio writes in (http://slexy.org/view/s2MsjllAyU) Sha'ul writes in (http://slexy.org/view/s20eYELsAg) John writes in (http://slexy.org/view/s20Y2GN1az) Sean writes in (http://slexy.org/view/s20ARVQ1T6) (TJ's lengthy reply (http://slexy.org/view/s212XezEYt)) Christopher writes in (http://slexy.org/view/s2DRgEv4j8) *** Mailing List Gold Special Instructions (https://lists.freebsd.org/pipermail/freebsd-questions/2015-February/264010.html) Pretending to be a VT220 (https://mail-index.netbsd.org/netbsd-users/2015/01/19/msg015669.html) ***

This time on the show, we've got an interview with Kristaps Džonsons, the creator of mandoc. He tells us how the project got started and what its current status is across the various BSDs. We also have a mini-tutorial on using PF to throttle bandwidth. This week's news, answers to your emails and even some cheesy mailing list gold, coming up on BSD Now - the place to B.. SD. This episode was brought to you by Headlines Updates to FreeBSD's random(4) (https://svnweb.freebsd.org/base?view=revision&revision=273872) FreeBSD's random device, which presents itself as "/dev/random" to users (https://news.ycombinator.com/item?id=8550457), has gotten a fairly major overhaul in -CURRENT The CSPRNG (cryptographically secure pseudo-random number generator) algorithm, Yarrow, now has a new alternative called Fortuna Yarrow is still the default for now, but Fortuna can be used with a kernel option (and will likely be the new default in 11.0-RELEASE) Pluggable modules can now be written to add more sources of entropy These changes are expected to make it in 11.0-RELEASE, but there hasn't been any mention of MFCing them to 10 or 9 *** OpenBSD Tor relays and network diversity (https://lists.torproject.org/pipermail/tor-relays/2014-November/005661.html) We've talked about getting more BSD-based Tor nodes (http://lists.nycbug.org/mailman/listinfo/tor-bsd) a few times in previous episodes The "tor-relays" mailing list has had some recent discussion about increasing diversity in the Tor network, specifically by adding more OpenBSD nodes With the security features and attention to detail, it makes for an excellent dedicated Tor box More and more adversaries are attacking Tor nodes, so having something that can withstand that will help the greater network at large A few users are even saying they'll convert their Linux nodes to OpenBSD to help out Check the archive for the full conversation, and maybe run a node yourself (http://www.bsdnow.tv/tutorials/tor) on any of the BSDs The Tor wiki page on OpenBSD is pretty out of date (https://lists.torproject.org/pipermail/tor-dev/2014-November/007715.html) (nine years old!?) and uses the old pf syntax, maybe one of our listeners can modernize it *** SSP now default for FreeBSD ports (https://lists.freebsd.org/pipermail/freebsd-ports/2014-November/096344.html) SSP, or Stack Smashing Protection (https://en.wikipedia.org/wiki/Buffer_overflow_protection), is an additional layer of protection against buffer overflows that the compiler can give to the binaries it produces It's now enabled by default in FreeBSD's ports tree, and the pkgng packages will have it as well - but only for amd64 (all supported releases) and i386 (10.0-RELEASE or newer) This will only apply to regular ports and binary packages, not the quarterly branch that only receives security updates If you were using the temporary "new Xorg" or SSP package repositories instead of the default ones, you need to switch back over NetBSD made this the default on i386 and amd64 two years ago (https://www.netbsd.org/releases/formal-6/NetBSD-6.0.html) and OpenBSD made this the default on all architectures twelve years ago (https://www.marc.info/?l=openbsd-cvs&m=103881967909595&w=2) Next time you rebuild your ports, things should be automatically hardened without any extra steps or configuration needed *** Building an OpenBSD firewall and router (https://www.reddit.com/r/BSD/comments/2ld0yw/building_an_openbsd_firewall_and_router/) While we've discussed the software and configuration of an OpenBSD router, this Reddit thread focuses more on the hardware side The OP lists some of his potential choices, but was originally looking for something a bit cheaper than a Soekris Most agree that, if it's for a business especially, it's worth the extra money to go with something that's well known in the BSD community They also list a few other popular alternatives: ALIX or the APU series from PC Engines, some Supermicro boards, etc. Through the comments, we also find out that QuakeCon runs OpenBSD on their network Hopefully most of our listeners are running some kind of BSD as their gateway - try it out (http://www.bsdnow.tv/tutorials/openbsd-router) if you haven't already *** Interview - Kristaps Džonsons - kristaps@bsd.lv (mailto:kristaps@bsd.lv) Mandoc, historical man pages, various topics Tutorial Throttling bandwidth with PF (http://www.bsdnow.tv/tutorials/openbsd-router#queues) News Roundup NetBSD at Kansai Open Forum 2014 (https://mail-index.netbsd.org/netbsd-advocacy/2014/11/08/msg000672.html) Japanese NetBSD users invade yet another conference, demonstrating that they can and will install NetBSD on everything From a Raspberry Pi to SHARP Netwalkers to various luna68k devices, they had it all As always, you can find lots of pictures in the trip report *** Getting to know your portmgr lurkers (http://blogs.freebsdish.org/portmgr/2014/11/04/getting-to-know-your-portmgr-lurker-ak/) The lovable "getting to know your portmgr" series makes its triumphant return This time around, they interview Alex, one of the portmgr lurkers that joined just this month "How would you describe yourself?" "Too lazy." Another post (http://blogs.freebsdish.org/portmgr/2014/11/08/getting-to-know-your-portmgr-lurker-ehaupt/) includes a short interview with Emanuel, another new lurker We discussed the portmgr lurkers initiative with Steve Wills a while back (http://www.bsdnow.tv/episodes/2014_10_01-the_daemons_apprentice) *** NetBSD's ARM port gets SMP (https://blog.netbsd.org/tnf/entry/working_arm_multiprocessor_support) The ARM port of NetBSD now has SMP support, allowing more than one CPU to be used This blog post on the website has a list of supported boards: Banana Pi, Cubieboard 2, Cubietruck, Merrii Hummingbird A31, CUBOX-I and NITROGEN6X NetBSD's release team is working on getting these changes into the 7 branch before 7.0 is released There are also a few nice pictures in the article *** A high performance mid-range NAS (http://pivotallabs.com/high-performing-mid-range-nas-server-part-2-performance-tuning-iscsi/) This blog post is about FreeNAS and optimizing iSCSI performance It talks about using mid-range hardware with FreeNAS and different tunables you can change to affect performance There are some nice graphs and lots of detail if you're interested in tweaking some of your own settings They conclude "there is no optimal configuration; rather, FreeNAS can be configured to suit a particular workload" *** Feedback/Questions Heto writes in (http://slexy.org/view/s2xGCUj8mC) Brad writes in (http://slexy.org/view/s2SJ8xppDJ) Tyler writes in (http://slexy.org/view/s20Ktl6BMk) Tim writes in (http://slexy.org/view/s2AsrxU0ZQ) Brad writes in (http://slexy.org/view/s21yn0xLv2) *** Mailing List Gold Suspicious contributions (https://www.marc.info/?t=141379917200003&r=1&w=2) La puissance du fromage (https://www.marc.info/?l=openbsd-cvs&m=141538800019451&w=2) Nothing unusual here (https://mail-index.netbsd.org/tech-ports/2002/07/05/0000.html) ***

This week on the show, it's all about Lumina. We'll be giving you a visual walkthrough of the new BSD-exclusive desktop environment, as well as chatting with the main developer. There's also answers to your emails and all the latest news, on BSD Now - the place to B.. SD. This episode was brought to you by Headlines Portscout ported to OpenBSD (http://blog.jasper.la/portscout-for-openbsd/) Portscout is a popular utility used in the FreeBSD ports infrastructure It lets port maintainers know when there's a new version of the upstream software available by automatically checking the distfile mirror Now OpenBSD porters can enjoy the same convenience, as it's been ported over You can view the status online (http://portscout.jasper.la/) to see how it works and who maintains what (http://portscout.jasper.la/index-total.html) The developer who ported it is working to get all the current features working on OpenBSD, and added a few new features as well He decided to fork and rename it (https://jasperla.github.io/portroach/) a few days later *** Sysadmins and systemd refugees flocking to BSD (https://www.reddit.com/r/freebsd/comments/2fgb90/you_have_your_windows_in_my_linux_or_why_many/) With all the drama in Linux land about the rapid changes to their init system, a lot of people are looking at BSD alternatives This "you got your Windows in my Linux (http://www.infoworld.com/d/data-center/you-have-your-windows-in-my-linux-249483)" article (and accompanying comments) give a nice glimpse into the minds of some of those switchers Both server administrators and regular everyday users are switching away from Linux, as more and more distros give them no choice but to use systemd Fortunately, the BSD communities are usually very welcoming of switchers - it's pretty nice on this side! *** OpenBSD's versioning schemes (http://www.tedunangst.com/flak/post/OpenBSD-version-numbers) Ted Unangst explains the various versioning systems within OpenBSD, from the base to libraries to other included software In contrast to FreeBSD's release cycle, OpenBSD isn't as concerned with breaking backwards compatibility (but only if it's needed to make progress) This allows them to innovate and introduce new features a lot more easily, and get those features in a stable release that everyone uses He also details the difference between branches, their errata system and lack of "patch levels" for security Some other things in OpenBSD don't have version numbers at all, like tmux "Every release adds some new features, fixes some old bugs, probably adds a new bug or two, and, if I have anything to say about it, removes some old features." *** VAXstation 4000 Model 90 booting NetBSD (https://www.youtube.com/watch?v=zLsgFPaMPyg) We found a video of NetBSD booting on a 22 year old VAX workstation, circa 1992 This system has a monstrous 71 MHz CPU and 128MB of ECC RAM It continues in part two (https://www.youtube.com/watch?v=YKzDXKmn66U), where we learn that it would've cost around $25,000 when it was released! The uploader talks about his experiences getting NetBSD on it, what does and doesn't work, etc It's interesting to see that such old hardware isn't necessarily obsolete just because newer things have come out since then (but maybe don't try to build world on it...) *** Interview - Ken Moore - ken@pcbsd.org (mailto:ken@pcbsd.org) The Lumina desktop environment Special segment Lumina walkthrough News Roundup Suricata for IDS on pfSense (http://pfsensesetup.com/suricata-intrusion-detection-system-part-one) While most people are familiar with Snort as an intrusion detection system, Suricata is another choice This guide goes through the steps of installing and configuring it on a public-facing pfSense box Part two (http://pfsensesetup.com/suricata-intrusion-detection-system-part-two/) details some of the configuration steps One other cool thing about Suricata - it's compatible with Snort rules, so you can use the same updates There's also another recent post (http://www.allamericancomputerrepair.com/Blog/Post/29/Install-Snort-on-FreeBSD) about snort as well, if that's more your style If you run pfSense (or any BSD) as an edge router for a lot of users, this might be worth looking into *** OpenBSD's systemd API emulation project (http://bsd.slashdot.org/story/14/09/08/0250207/gsoc-project-works-to-emulate-systemd-for-openbsd) This story was pretty popular in the mainstream news this week For the Google Summer of Code, a student is writing emulation wrappers for some of systemd's functions (https://twitter.com/blakkheim/status/509092821773848577) There was consideration from some Linux users to port over the finished emulation back to Linux, so they wouldn't have to run the full systemd One particularly interesting Slashdot comment snippet (http://bsd.slashdot.org/comments.pl?sid=5663319&cid=47851361): "We are currently migrating a large number (much larger than planned after initial results) of systems from RHEL to BSD - a decision taken due to general unhappiness with RHEL6, but SystemD pushed us towards BSD rather than another Linux distro - and in some cases are seeing throughput gains of greater than 10% on what should be equivalent Linux and BSD server builds. The re-learning curve wasn't as steep as we expected, general system stability seems to be better too, and BSD's security reputation goes without saying." It will NOT be in the base system - only in ports, and only installed as a dependency for things like newer GNOME (http://blogs.gnome.org/ovitters/2014/09/07/systemd-in-gnome-3-14-and-beyond/) that require such APIs In the long run, BSD will still be safe from systemd's reign of terror, but will hopefully still be compatible with some third party packages like GNOME that insist on using it *** GhostBSD 4 previewed (http://www.linuxbsdos.com/2014/05/19/preview-of-ghostbsd-4-0/) The GhostBSD project is moving along, slowly getting closer to the 4 release This article shows some of the progress made, and includes lots of screenshots and interesting graphical frontends If you're not too familiar with GhostBSD, we interviewed the lead developer (http://www.bsdnow.tv/episodes/2014_03_12-ghost_of_partition) a little while back *** NetBSD on the Banana Pi (http://rizzoandself.blogspot.com/2014/09/netbsd-on-banana-pi.html) The Banana Pi is a tasty alternative to the Raspberry Pi, with similar hardware specs In this blog post, a NetBSD developer details his experiences in getting NetBSD to run on it After studying how the prebuilt Linux image booted, he made some notes and started hacking Ethernet, one of the few things not working, is being looked into and he's hoping to get it fully supported for the upcoming NetBSD 7.0 They're only about $65 as of the time we're recording this, so it might be a fun project to try *** Feedback/Questions Antonio writes in (http://slexy.org/view/s28iKdBEbm) Garegin writes in (http://slexy.org/view/s21Wfnv87h) Erno writes in (http://slexy.org/view/s2Fzryxhdz) Brandon writes in (http://slexy.org/view/s2ILcqdFfF) ***
