Created by three guys who love BSD, we cover the latest news and have an extensive series of tutorials, as well as interviews with various people from all areas of the BSD community. It also serves as a platform for support and questions. We love and advocate FreeBSD, OpenBSD, NetBSD, DragonFlyBSD and TrueOS. Our show aims to be helpful and informative for new users that want to learn about them, but still be entertaining for the people who are already pros. The show airs on Wednesdays at 2:00PM (US Eastern time) and the edited version is usually up the following day.

70: Daemons in the North
It's our last episode of 2014, and we'll be chatting with Dan Langille about the upcoming BSDCan conference. We'll find out what's planned and what sorts of presentations they're looking for. As usual, answers to viewer-submitted questions and all the week's news, coming up on BSD Now - the place to B.. SD. This episode was brought to you by Headlines More conference presentation videos (http://2014.asiabsdcon.org/timetable.html.en) Some more of the presentation videos from AsiaBSDCon are appearing online Masanobu Saitoh, Developing CPE Routers Based on NetBSD (https://www.youtube.com/watch?v=ApruZrU5fVs) Reyk Floeter (http://www.bsdnow.tv/episodes/2014_09_03-its_hammer_time), VXLAN and Cloud-based Networking with OpenBSD (https://www.youtube.com/watch?v=ufeEP_hzFN0) Jos Jansen, Adapting OS X to the enterprise (https://www.youtube.com/watch?v=gOPfRQgTjNo) Pierre Pronchery (http://www.bsdnow.tv/episodes/2014_04_01-edgy_bsd_users) & Guillaume Lasmayous, Carve your NetBSD (https://www.youtube.com/watch?v=vh-TjLUj6os) Colin Percival (http://www.bsdnow.tv/episodes/2014_01_22-tendresse_for_ten), Everything you need to know about cryptography in 1 hour (https://www.youtube.com/watch?v=jzY3m5Kv7Y8) (not from AsiaBSDCon) The "bsdconferences" YouTube channel has quite a lot of interesting older BSD talks (https://www.youtube.com/user/bsdconferences/videos?sort=da&view=0&flow=grid) too - you may want to go back and watch them if you haven't already *** OpenBSD PIE enhancements (https://www.marc.info/?l=openbsd-cvs&m=141922027318727&w=2) ASLR (https://en.wikipedia.org/wiki/Address_space_layout_randomization) and PIE (https://en.wikipedia.org/wiki/Position-independent_executable) are great security features that OpenBSD has had enabled by default for a long time, in both the base system and ports, but they have one inherent problem They only work with dynamic libraries and binaries, so if you have any static binaries, they don't get the same treatment For example, the default shells (and many other things in /bin and /sbin) are statically linked In the case of the static ones, you can always predict the memory layout, which is very bad and sort of defeats the whole purpose (https://en.wikipedia.org/wiki/Return-oriented_programming) With this and a few related commits (https://www.marc.info/?l=openbsd-cvs&m=141927571832106&w=2), OpenBSD fixes this by introducing static self-relocation More and more CPU architectures are being tested and getting support too; this isn't just for amd64 and i386 - VAX users can rest easy It'll be available in 5.7 in May, or you can use a -current snapshot (http://www.openbsd.org/faq/faq5.html#BldBinary) if you want to get a slice of the action now *** FreeBSD foundation semi-annual newsletter (https://www.freebsdfoundation.org/press/2014dec-newsletter.html) The FreeBSD foundation publishes a huge newsletter twice a year, detailing their funded projects and some community activities As always, it starts with a letter from the president of the foundation - this time it's about encouraging students and new developers to get involved The article also has a fundraising update with a list of sponsored projects, and they note that the donations meter has changed from dollars to number of donors (since they exceeded the goal already) You can read summaries of all the BSD conferences of 2014 and see a list of upcoming ones next year too There are also sections about the FreeBSD Journal (http://www.bsdnow.tv/episodes/2014_01_29-journaled_news_updates)'s progress, a new staff member and a testimonial from NetApp It's a very long report, so dedicate some time to read all the way through it This year was pretty great for BSD: both the FreeBSD and OpenBSD foundations exceeded their goals and the NetBSD foundation came really close too As we go into 2015, consider donating to whichever (https://www.freebsdfoundation.org/donate) BSD (http://www.openbsdfoundation.org/donations.html) you (https://www.netbsd.org/donations/) use (http://www.dragonflybsd.org/donations/), it really can make a difference *** Modernizing OpenSSH fingerprints (https://www.marc.info/?l=openbsd-cvs&m=141920089614758&w=4) When you connect to a server for the first time, you'll get what's called a fingerprint of the host's public key - this is used to verify that you're actually talking to the same server you intended to Up until now, the key fingerprints have been an MD5 hash, displayed as hex This can be problematic (https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-November/033117.html), especially for larger key types like RSA that give lots of wiggle room for collisions, as an attacker could generate a fake host key that gives the same MD5 string as the one you wanted to connect to This new change replaces the default MD5 and hex with a base64-encoded SHA256 fingerprint You can add a "FingerprintHash" line in your ssh_config to force using only the new type There's also a new option (https://www.marc.info/?l=openbsd-cvs&m=141923470520906&w=2) to require users to authenticate with more than one public key, so you can really lock down login access to your servers - also useful if you're not 100% confident in any single key type The new options should be in the upcoming 6.8 release *** Interview - Dan Langille - info@bsdcan.org (mailto:info@bsdcan.org) / @bsdcan (https://twitter.com/bsdcan) Plans for the BSDCan 2015 conference News Roundup Introducing ntimed, a new NTP daemon (https://github.com/bsdphk/Ntimed) As we've mentioned before in our tutorials (http://www.bsdnow.tv/tutorials/ntpd), there are two main daemons for the Network Time Protocol - ISC's NTPd and OpenBSD's OpenNTPD With all the recent security problems with ISC's NTPd, Poul-Henning Kamp (http://www.bsdnow.tv/episodes/2013_10_16-go_directly_to_jail) has been working on a third NTP daemon It's called "ntimed" and you can try out a preview version of it right now - it's in FreeBSD ports (https://www.freshports.org/net/ntimed/) or on Github PHK also has a few blog entries (http://phk.freebsd.dk/time/) about the project, including status updates *** OpenBSD-maintained projects list (http://mdocml.bsd.lv/openbsd_projects.html) There was recently a read on the misc mailing list (https://www.marc.info/?t=141961588200003&r=1&w=2) asking about different projects started by OpenBSD developers The initial list had marks for which software had portable versions to other operating systems (OpenSSH being the most popular example) A developer compiled a new list from all of the replies to that thread into a nice organized webpage Most people are only familiar with things like OpenSSH, OpenSMTPD, OpenNTPD and more recently LibreSSL, but there are quite a lot more This page also serves as a good history lesson for BSD in general: FreeBSD and others have ported some things over, while a couple OpenBSD tools were born from forks of FreeBSD tools (mergemaster, pkg tools, portscout) *** Monitoring network traffic with FreeBSD (https://forums.freebsd.org/threads/howto-monitor-network-traffic-with-netflow-nfdump-nfsen-on-freebsd.49724/) If you've ever been curious about monitoring network traffic on your FreeBSD boxes, this forum post may be exactly the thing for you It'll show you how to combine the Netflow, NfDump and NfSen suite of tools to get some pretty detailed network stats (and of course put them into a fancy webpage) This is especially useful for finding out what was going on at a certain point in time, for example if you had a traffic spike *** Trapping spammers with spamd (http://www.protoc.org/blog/2014/12/22/trapping-spammers-with-the-openbsd-spam-deferral-daemon) This is a blog post about OpenBSD's spamd (https://en.wikipedia.org/wiki/Spamd) - a spam email deferral daemon - and how to use it for your mail It gives some background on the greylisting approach to spam, rather than just a typical host blacklist "Greylisting is a method of defending e-mail users against spam. A mail transfer agent (MTA) using greylisting will "temporarily reject" any email from a sender it does not recognize. If the sender re-attempts mail delivery at a later time, the sender may be allowed to continue the mail delivery conversation." The post also shows how to combine it with PF and other tools for a pretty fancy mail setup You can find spamd in the OpenBSD base system (http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man8/spamd.8), or use it with FreeBSD (https://www.freshports.org/mail/spamd) or NetBSD (http://pkgsrc.se/mail/spamd) via ports and pkgsrc You might also want to go back and listen to BSDTalk episode 68 (https://archive.org/details/bsdtalk068), where Will talks to Bob Beck about spamd *** Feedback/Questions Sean writes in (http://slexy.org/view/s20rUK9XVJ) Brandon writes in (http://slexy.org/view/s20nfzIuT2) Anders writes in (http://slexy.org/view/s20wCBhFLO) David writes in (http://slexy.org/view/s20xGrBIyl) Kyle writes in (http://slexy.org/view/s2QHRaiZJW) *** Mailing List Gold NTP code comparison (https://www.marc.info/?l=openbsd-tech&m=141903858708123&w=2) - 192870 vs. 2898 (https://www.marc.info/?l=openbsd-tech&m=141905854411370&w=2) NICs have feelings too (https://lists.freebsd.org/pipermail/freebsd-hackers/2014-December/046741.html) Just think about it (https://www.marc.info/?l=openbsd-ports&m=141998130824977&w=2) ***

67: Must Be Rigged
Coming up this week on the show, we've got an interview with Patrick Wildt, one of the developers of Bitrig. We'll find out all the details of their OpenBSD fork, what makes it different and what their plans are going forward. We've also got all the week's news and answers to your emails, on BSD Now - the place to B.. SD. This episode was brought to you by Headlines Bitrig 1.0 released (http://article.gmane.org/gmane.os.bitrig.devel/6) If you haven't heard of it, Bitrig (https://www.bitrig.org/) is a fork of OpenBSD that started a couple years ago According to their FAQ (https://github.com/bitrig/bitrig/wiki/Faq), some of their goals include: only supporting modern hardware and a limited set of CPU architectures, replacing nearly all GNU tools in base with BSD versions and having better virtualization support They've finally announced their first official release, 1.0 This release introduces support for Clang 3.4, replacing the old GCC, along with libc++ replacing the GNU version It also includes filesystem journaling, support for GPT and - most importantly - a hacker-style console with green text on black background One of the developers answered some questions (https://news.ycombinator.com/item?id=8701936) about it on Hacker News too *** Is it time to try BSD? (http://www.technewsworld.com/story/81424.html) Here we get a little peek into the Linux world - more and more people are considering switching On a more mainstream tech news site, they have an article about people switching away from Linux and to BSD People are starting to get even more suspicious of systemd, and lots of drama in the Linux world is leading a whole new group of potential users over to the BSD side This article explores some pros and cons of switching, and features opinions of various users *** Poudriere 3.1 released (https://github.com/freebsd/poudriere/wiki/release_notes_31) One of the first things we ever covered on the show was poudriere (http://www.bsdnow.tv/tutorials/poudriere), a tool with a funny name that's used to build binary packages from FreeBSD ports It's come a long way since then, and bdrewery (http://www.bsdnow.tv/episodes/2014_07_16-network_iodometry) and bapt (http://www.bsdnow.tv/episodes/2014_01_01-eclipsing_binaries) have just announced a new major version This new release features a redesigned web interface to check on the status of your packages There are lots of new bulk building options to preserve packages even if some fail to compile - this makes maintaining a production repo much easier It also introduces a useful new "pkgclean" subcommand to clean out your repository of packages that aren't needed anymore, and poudriere keeps it cleaner by default as well now Check the full release notes for all the additions and bug fixes *** Firewalling with OpenBSD's pf and pfsync (https://www.youtube.com/watch?v=mN5E2EYJnrw) A talk by David Gwynne from an Australian conference was uploaded, with the subject matter being pf and pfsync He uses pf to manage 60 internal networks with a single firewall The talk gives some background on how pf originally came to be and some OpenBSD 101 for the uninitiated It also touches on different rulesets, use cases, configuration syntax, placing limits on connections, ospf, authpf, segregating VLANs, synproxy handling and a lot more The second half of the presentation focuses on pfsync and carp for failover and redundancy With two BSD boxes running pfsync, you can actually patch your kernel and still stay connected to IRC *** Interview - Patrick Wildt - patrick@bitrig.org (mailto:patrick@bitrig.org) / @bitrig (https://twitter.com/bitrig) The initial release of Bitrig News Roundup Infrastructural enhancements at NYI (http://freebsdfoundation.blogspot.com/2014/12/the-freebsd-cluster-infrastructural.html) The FreeBSD foundation put up a new blog post detailing some hardware improvements they've recently done Their eastern US colocation is hosted at New York Internet, and is used for FTP mirrors, pkgng mirrors, and also as a place for developers to test things There've been fourteen machines purchased since July, and now FreeBSD boasts a total of sixty-eight physical boxes there This blog post goes into detail about how those servers are used and details some of the network topology *** The long tail of MD5 (http://www.tedunangst.com/flak/post/the-long-tail-of-MD5) Our friend Ted Unangst is on a quest to replace all instances of MD5 in OpenBSD's tree with something more modern In this blog post, he goes through some of the different areas where MD5 still lives, and discovers how easy (or impossible) it would be to replace Through some recent commits, OpenBSD now uses SHA512 in some places that you might not expect Some other places (https://www.marc.info/?l=openbsd-cvs&m=141763065223567&w=4) require a bit more care… *** DragonFly cheat sheet (http://www.dragonflybsd.org/varialus/) If you've been thinking of trying out DragonFlyBSD lately, this might make the transition a bit easier A user-created "cheat sheet" on the website lists some common answers to beginner questions The page features a walkthrough of the installer, some shell tips and workarounds for various issues At the end, it also has some things that new users can get involved with to help out *** Experiences with an OpenBSD laptop (http://alxjsn.com/unix/openbsd-laptop/) A lot of people seem to be interested in trying out some form of BSD on their laptop, and this article details just that The author got interested in OpenBSD mostly because of the security focus and the fact that it's not Linux In this blog post, he goes through the steps of researching, installing, configuring, upgrading and finally actually using it on his Thinkpad He even gives us a mention as a good place to learn more about BSD, thanks!

(https://www.marc.info/?l=openbsd-tech&m=141614801713457&w=2) Even more DJB crypto somehow finds its way into OpenBSD's base system This time it's SipHash (https://131002.net/siphash/), a family of pseudorandom functions that's resistant to hash bucket flooding attacks while still providing good performance After an initial import (http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/crypto/siphash.c?rev=1.1&content-type=text/x-cvsweb-markup) and some clever early usage (https://www.marc.info/?l=openbsd-cvs&m=141604896822253&w=2), a few developers agreed that it would be better to use it in a lot more places It will now be used in the filesystem, and the plan is to utilize it to protect all kernel hash functions Some other places (http://www.bsdnow.tv/episodes/2013_12_18-cryptocrystalline) that Bernstein's work can be found in OpenBSD include the ChaCha20-Poly1305 authenticated stream cipher and Curve25519 KEX used in

(https://www.freebsd.org/releases/10.1R/announce.html) FreeBSD's release engineering team (http://www.bsdnow.tv/episodes/2013-09-11_engineering_powder_kegs) likes to troll us by uploading new versions just a few hours after we finish recording an episode The first maintenance update for the 10.x branch is out, improving upon a lot of things found in 10.0-RELEASE The vt driver was merged from -CURRENT and can now be enabled with a loader.conf switch (and can even be used on a PlayStation 3) Bhyve has gotten quite a lot of fixes and improvements from its initial debut in 10.0, including boot support for ZFS Lots of new ARM hardware is supported now, including SMP support for most of them A new kernel selection menu was added to the loader, so you can switch between newer and older kernels at boot time 10.1 is the first to support UEFI booting on amd64, which also has serial console support now Lots of third party software (OpenSSH, OpenSSL, Unbound..) and drivers have gotten updates to newer versions It's a worthy update from 10.0, or a good time to try the 10.x branch if you were avoiding the first .0 release, so grab an ISO (http://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-amd64/10.1/) or upgrade (https://www.freebsd.org/cgi/man.cgi?query=freebsd-update) today Check the detailed release notes

of their own unique features and changes *** arc4random - Randomization for All Occasions (https://www.youtube.com/watch?v=aWmLWx8ut20) Theo de Raadt gave an updated version of his EuroBSDCon presentation at Hackfest 2014 in Quebec The presentation is mainly about OpenBSD's arc4random function, and outlines the overall poor state of randomization in the 90s and how it has evolved in OpenBSD over time It begins with some interesting history on OpenBSD and how it became a security-focused OS - in 1996, their syslogd got broken into and "suddenly we became interested in security" The talk also touches on how low-level changes can shake up the software ecosystem and third party packages that everyone uses There's some funny history on the name of the function (being called arc4random despite not using RC4 anymore) and an overall status update on various platforms' usage of it Very detailed and informative presentation, and the slides can be found here (http://www.openbsd.org/papers/hackfest2014-arc4random/index.html) A great quote from the beginning: "We consider ourselves a community of (probably rather strange) people who work on software specifically for the purpose of trying to make it better. We take a 'whole-systems' approach: trying to change everything in the ecosystem that's under our control, trying to see if we can make it better. We gain a lot of strength by being able to throw backwards compatibility out the window. So that means that we're able to do research and the minute that we decide that something isn't right, we'll design an alternative for it and push it in. And if it ends up breaking everybody's machines from the previous stage to the next stage, that's fine because we'll end up in a happier place." *** Interview - Justin Cormack - justin@netbsd.org (mailto:justin@netbsd.org) / @justincormack (https://twitter.com/justincormack) NetBSD on Xen, rump kernels, various topics News Roundup The FreeBSD foundation's biggest donation (http://freebsdfoundation.blogspot.com/2014/11/freebsd-foundation-announces-generous.html) The FreeBSD foundation has a new blog post about the largest donation they've ever gotten From the CEO of WhatsApp comes a whopping one million dollars in a single donation It also has some comments from the donor about why they use BSD and why it's important to give back Be sure to donate to the foundation of whatever BSD you use when you can - every little bit helps, especially for OpenBSD (http://www.openbsd.org/donations.html), NetBSD (https://www.netbsd.org/donations/) and DragonFly (http://www.dragonflybsd.org/donations/) who don't have huge companies supporting them regularly like FreeBSD does *** OpenZFS Dev Summit 2014 videos (http://open-zfs.org/wiki/OpenZFS_Developer_Summit) Videos from the recent OpenZFS developer summit are being uploaded, with speakers from different represented platforms and companies Matt Ahrens (http://www.bsdnow.tv/episodes/2014_05_14-bsdcanned_goods), opening keynote (https://www.youtube.com/watch?v=XnTzbisLYzg) Raphael Carvalho, Platform Overview: ZFS on OSv (https://www.youtube.com/watch?v=TJLOBLSRoHE) Brian Behlendorf, Platform Overview: ZFS on Linux (https://www.youtube.com/watch?v=_MVOpMNV7LY) Prakash Surya, Platform Overview: illumos (https://www.youtube.com/watch?v=UtlGt3ag0o0) Xin Li, Platform Overview: FreeBSD (https://www.youtube.com/watch?v=xO0x5_3A1X4) All platforms, Group Q&A Session (https://www.youtube.com/watch?v=t4UlT0RmSCc) Dave Pacheco, Manta (https://www.youtube.com/watch?v=BEoCMpdB8WU) Saso Kiselkov, Compression (https://www.youtube.com/watch?v=TZF92taa_us) George Wilson (http://www.bsdnow.tv/episodes/2013_12_04-zettabytes_for_days), Performance (https://www.youtube.com/watch?v=deJc0EMKrM4) Tim Feldman, Host-Aware SMR (https://www.youtube.com/watch?v=b1yqjV8qemU) Pavel Zakharov, Fast File Cloning (https://www.youtube.com/watch?v=-4c4gsLi1LI) The audio is pretty poor (https://twitter.com/OpenZFS/status/534005125853888512) on all of them unfortunately *** BSDTalk 248 (http://bsdtalk.blogspot.com/2014/11/bsdtalk248-dragonflybsd-with-matthew.html) Our friend Will Backman is still busy getting BSD interviews as well This time he sits down with Matthew Dillon, the lead developer of DragonFly BSD We've never had Dillon on the show, so you'll definitely want to give this one a listen They mainly discuss all the big changes coming in DragonFly's upcoming 4.0 release *** MeetBSD 2014 videos (https://www.meetbsd.com/) The presentations from this year's MeetBSD conference are starting to appear online as well Kirk McKusick (http://www.bsdnow.tv/episodes/2013-10-02_stacks_of_cache), A Narrative History of BSD (https://www.youtube.com/watch?v=DEEr6dT-4uQ) Jordan Hubbard (http://www.bsdnow.tv/episodes/2013_11_27-bridging_the_gap), FreeBSD: The Next 10 Years (https://www.youtube.com/watch?v=Mri66Uz6-8Y) Brendan Gregg, Performance Analysis (https://www.youtube.com/watch?v=uvKMptfXtdo) The slides can be found here (https://www.meetbsd.com/agenda/) *** Feedback/Questions Dominik writes in (http://slexy.org/view/s20PXjp55N) Steven writes in (http://slexy.org/view/s2LwEYT3bA) Florian writes in (http://slexy.org/view/s2ubK8vQVt) Richard writes in (http://slexy.org/view/s216Eq8nFG) Kevin writes in (http://slexy.org/view/s21D2ugDUy) *** Mailing List Gold Contributing without code (https://www.marc.info/?t=141600819500004&r=1&w=2) Compression isn't a CRIME (https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-November/033176.html) Securing web browsers (https://www.marc.info/?t=141616714600001&r=1&w=2) ***
63: A Man's man(1)
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."

62: Gift from the Sun
We're away at MeetBSD this week, but we've still got a great show for you. We'll be joined by Pawel Dawidek, who's done quite a lot of things in FreeBSD over the years, including the initial ZFS port. We'll get to hear how that came about, what he's up to now and a whole lot more. We'll be back next week with a normal episode of BSD Now - the place to B.. SD. This episode was brought to you by Interview - Pawel Jakub Dawidek - pjd@freebsd.org (mailto:pjd@freebsd.org) Porting ZFS, GEOM, GELI, Capsicum, various topics
61: IPSECond Wind
This week on the show, we sat down with John-Mark Gurney to talk about modernizing FreeBSD's IPSEC stack. We'll learn what he's adding, what needed to be fixed and how we'll benefit from the changes. As always, answers to your emails and all of this week's news, on BSD Now - the place to B.. SD. This episode was brought to you by Headlines BSD panel at Phoenix LUG (https://www.youtube.com/watch?v=3AOF7fm-TJ0) The Phoenix, Arizona Linux users group had a special panel so they could learn a bit more about BSD It had one FreeBSD user and one OpenBSD user, and they answered questions from the organizer and the people in the audience They covered a variety of topics, including filesystems, firewalls, different development models, licenses and philosophy It was a good "real world" example of things potential switchers are curious to know about They closed by concluding that more diversity is always better, and even if you've got a lot of Linux boxes, putting a few BSD ones in the mix is a good idea *** Book of PF signed copy auction (http://bsdly.blogspot.com/2014/10/the-book-of-pf-3rd-edition-is-here.html) Peter Hansteen (who we've had on the show (http://www.bsdnow.tv/episodes/2014_04_30-puffy_firewall)) is auctioning off the first signed copy of the new Book of PF All the profits from the sale will go to the OpenBSD Foundation (http://www.openbsd.org/donations.html) The updated edition of the book includes all the latest pf syntax changes, but also provides examples for FreeBSD and NetBSD's versions (which still use ALTQ, among other differences) If you're interested in firewalls, security or even just advanced networking, this book is a great one to have on your shelf - and the money will also go to a good cause Michael Lucas (http://www.bsdnow.tv/episodes/2013_11_06-year_of_the_bsd_desktop) has challenged Peter (https://www.marc.info/?l=openbsd-misc&m=141429413908567&w=2) to raise more for the foundation than his last book selling - let's see who wins Pause the episode, go bid on it (http://www.ebay.com/itm/321563281902) and then come back! *** FreeBSD Foundation goes to EuroBSDCon (http://freebsdfoundation.blogspot.com/2014/10/freebsd-foundation-goes-to-eurobsdcon.html) Some people from the FreeBSD Foundation went to EuroBSDCon this year, and come back with a nice trip report They also sponsored four other developers to go The foundation was there "to find out what people are working on, what kind of help they could use from the Foundation, feedback on what we can be doing to support the FreeBSD Project and community, and what features/functions people want supported in FreeBSD" They also have a second report (http://freebsdfoundation.blogspot.com/2014/10/eurobsdcon-trip-report-kamil-czekirda.html) from Kamil Czekirda A total of $2000 was raised at the conference *** OpenBSD 5.6 released (http://www.openbsd.org/56.html) Note: we're doing this story a couple days early - it's actually being released on November 1st (this Saturday), but we have next week off and didn't want to let this one slip through the cracks - it may be out by the time you're watching this Continuing their always-on-time six month release cycle, the OpenBSD team has released version 5.6 It includes support for new hardware, lots of driver updates, network stack improvements (SMP, in particular) and new security features 5.6 is the first formal release with LibreSSL, their fork of OpenSSL, and lots of ports have been fixed to work with it You can now hibernate your laptop when using a fully-encrypted filesystem (see our tutorial (http://www.bsdnow.tv/tutorials/fde) for that) ALTQ, Kerberos, Lynx, Bluetooth, TCP Wrappers and Apache were all removed This will serve as a "transitional" release for a lot of services: moving from Sendmail to OpenSMTPD, from nginx to httpd (http://www.bsdnow.tv/episodes/2014_09_03-its_hammer_time) and from BIND to Unbound Sendmail, nginx and BIND will be gone in the next release, so either migrate to the new stuff between now and then or switch to the ports versions As always, 5.6 comes with its own song and artwork (http://www.openbsd.org/lyrics.html#56) - the theme this time was obviously LibreSSL Be sure to check the full changelog (http://www.openbsd.org/plus56.html) (it's huge) and pick up a CD or tshirt (http://www.openbsd.org/orders.html) to support their efforts If you don't already have the public key releases are signed with, getting a physical CD is a good "out of bounds" way to obtain it safely Here are some cool images of the set (https://imgur.com/a/5PtFe) After you do your installation or upgrade (http://www.openbsd.org/faq/upgrade56.html), don't forget to head over to the errata page (http://www.openbsd.org/errata56.html) and apply any patches listed there *** Interview - John-Mark Gurney - jmg@freebsd.org (mailto:jmg@freebsd.org) / @encthenet (https://twitter.com/encthenet) Updating FreeBSD's IPSEC stack News Roundup Clang in DragonFly BSD (https://www.dragonflydigest.com/2014/10/22/14942.html) As we all know, FreeBSD got rid of GCC in 10.0, and now uses Clang almost exclusively on i386/amd64 Some DragonFly developers are considering migrating over as well, and one of them is doing some work to make the OS more Clang-friendly We'd love to see more BSDs switch to Clang/LLVM eventually, it's a lot more modern than the old GCC most are using *** reallocarray(): integer overflow detection for free (http://lteo.net/blog/2014/10/28/reallocarray-in-openbsd-integer-overflow-detection-for-free/) One of the less obvious features in OpenBSD 5.6 is a new libc function: "reallocarray()" It's a replacement function for realloc(3) that provides integer overflow detection at basically no extra cost Theo and a few other developers have already started (https://secure.freshbsd.org/search?project=openbsd&q=reallocarray) a mass audit of the entire source tree, replacing many instances with this new feature OpenBSD's explicit_bzero was recently imported into FreeBSD, maybe someone could also port over this too *** Switching from Linux blog (http://bothsidesofthence.tumblr.com/) A listener of the show has started a new blog series, detailing his experiences in switching over to BSD from Linux After over ten years of using Linux, he decided to give BSD a try after listening to our show (which is awesome) So far, he's put up a few posts about his initial thoughts, some documentation he's going through and his experiments so far It'll be an ongoing series, so we may check back in with him again later on *** Owncloud in a FreeNAS jail (https://www.youtube.com/watch?v=z6VQwOl4wE4) One of the most common emails we get is about running Owncloud in FreeNAS Now, finally, someone made a video on how to do just that, and it's even jailed A member of the FreeNAS community has uploaded a video on how to set it up, with lighttpd as the webserver backend If you're looking for an easy way to back up and sync your files, this might be worth a watch *** Feedback/Questions Ernõ writes in (http://slexy.org/view/s2XEsQdggZ) David writes in (http://slexy.org/view/s21EizH2aR) Kamil writes in (http://slexy.org/view/s24SAJ5im6) Torsten writes in (http://slexy.org/view/s20ABZe0RD) Dominik writes in (http://slexy.org/view/s208jQs9c6) *** Mailing List Gold That's not our IP (https://mail-index.netbsd.org/source-changes/2014/10/17/msg059564.html) Is this thing on?

This episode was brought to you by Headlines BSD Devroom CFP (https://lists.fosdem.org/pipermail/fosdem/2014-October/002038.html) This year's FOSDEM conference (Belgium, Jan 31st - Feb 1st) is having a dedicated BSD devroom They've issued a call for papers on anything BSD-related, and we always love more presentations If you're in the Belgium area or plan on going, submit a talk about something cool you're doing There's also a mailing list (https://lists.fosdem.org/listinfo/bsd-devroom) and some more information in the original post *** Bhyve SVM code merge (https://lists.freebsd.org/pipermail/freebsd-virtualization/2014-October/002905.html) The bhyve_svm code has been in the "projects" tree of FreeBSD, but is now ready (https://svnweb.freebsd.org/base?view=revision&revision=273375) for -CURRENT This changeset will finally allow bhyve to run on AMD CPUs, where it was previously limited to Intel only All the supported operating systems and utilities should work on both now One thing to note: bhyve doesn't support PCI passthrough on AMD just yet There may still be some issues (https://lists.freebsd.org/pipermail/freebsd-virtualization/2014-October/002935.html) though *** NetBSD at Open Source Conference Tokyo (https://mail-index.netbsd.org/netbsd-advocacy/2014/10/20/msg000671.html) The Japanese NetBSD users group held a booth at another recent open source conference As always, they were running NetBSD on everything you can imagine One of the users reports back to the mailing list on their experience, providing lots of pictures and links Here's an interesting screenshot of NetBSD running various other BSDs in Xen (https://pbs.twimg.com/media/B0NnfcbCEAAmKIU.jpg:large) *** More BSD switchers every day (https://www.reddit.com/r/unix/comments/2il383/question_about_the_bsd_community_as_a_whole/) A decade-long Linux user is considering making the switch, and asks Reddit about the BSD community Tired of the pointless bickering he sees in his current community, he asks if the same problems exist over here and what he should expect So far, he's found that BSD people seem to act more level-headed about things, and are much more practical, whereas some FSF/GNU/GPL people make open source a religion There's also another semi-related thread (https://www.reddit.com/r/BSD/comments/2jpxj9/question_about_the_current_state_of_freebsd/) about another Linux user wanting to switch to BSD because of systemd and GNU people There are some extremely well written and thought-out comments in the replies (in both threads), be sure to give them all a read Maybe the OPs should've just watched this show *** Interview - Olivier Cochard-Labbé - olivier@cochard.me (mailto:olivier@cochard.me) / @ocochardlabbe (https://twitter.com/ocochardlabbe) The BSD Router Project News Roundup FreeBSD -CURRENT on a T420 (https://www.banym.de/freebsd/install-freebsd-11-on-thinkpad-t420) Thinkpads are quite popular with BSD developers and users Most of the hardware seems to be supported across the BSDs (especially wifi) This article walks through installing FreeBSD -CURRENT on a Thinkpad T420 with UEFI If you've got a Thinkpad, or especially this specific one, have a look at some of the steps involved *** FreeNAS on a Supermicro 5018A-MHN4 (https://www.teckelworks.com/2014/10/building-a-freenas-server-with-a-supermicro-5018a-mhn4/) More and more people are migrating their NAS devices to BSD-based solutions In this post, the author goes through setting up FreeNAS on some of his new hardware His new rack-mounted FreeNAS machine has a low power Atom with eight cores and 64GB of RAM - quite a lot for its small form factor The rest of the post details all of the hardware he chose and goes through the build process (with lots of cool pictures) *** Hardening procfs and linprocfs (http://hardenedbsd.org/article/shawn-webb/2014-10-15/hardening-procfs-and-linprocfs) There was an exploit published recently for SFTP in OpenSSH, but it mostly just affected Linux There exists a native procfs in FreeBSD, which was the target point of that exploit, but it's not used very often The Linux emulation layer also supports its own linprocfs, which was affected as well The HardenedBSD guys weigh in on how to best solve the problem, and now support an additional protection layer from writing to memory with procfs If you want to learn more about ASLR and HardenedBSD, be sure to check out our interview with Shawn (http://www.bsdnow.tv/episodes/2014_08_27-reverse_takeover) too *** pfSense monitoring with bandwidthd (http://pfsensesetup.com/bandwidth-monitoring-with-bandwidthd/) A lot of people run pfSense on their home network, and it's really useful to monitor the bandwidth usage This article will walk you through setting up bandwidthd to do exactly that bandwidthd monitors based on the IP address, rather than per-interface It can also build some cool HTML graphs, and we love those pfSense graphs Have a look at our bandwidth monitoring and testing (http://www.bsdnow.tv/tutorials/vnstat-iperf) tutorial for some more ideas *** Feedback/Questions Dave writes in (http://slexy.org/view/s2b5ZZ5qCv) Chris writes in (http://slexy.org/view/s20aVvhv2d) Zeke writes in (http://slexy.org/view/s2Vmwxy1QM) Bostjan writes in (http://slexy.org/view/s2LB6MKoNT) Patrick writes in (http://slexy.org/view/s2xxB9uOuV) *** Mailing List Gold More (https://www.marc.info/?l=openbsd-tech&m=141357595922692&w=2) old bugs (https://www.marc.info/?l=openbsd-cvs&m=141358124924479&w=2) The Right Font™ (https://www.marc.info/?l=openbsd-cvs&m=141332534304117&w=2) (see also (https://twitter.com/blakkheim/status/522162864409546753)) ***

We also get to hear about how he got on the core team, and we just might find out why NetBSD is so popular over there! Answers to all your emails, the latest news, and even a brand new segment, on BSD Now - the place to B.. SD. This episode was brought to you by Headlines BSD talks at XDC 2014 (https://www.youtube.com/channel/UCXlH5v1PkEhjzLFTUTm_U7g/videos) This year's Xorg conference featured a few BSD-related talks Matthieu Herrb, Status of the OpenBSD graphics stack (https://www.youtube.com/watch?v=KopgD4nTtnA) Matthieu's talk details what's been done recently in Xenocara the OpenBSD kernel for graphics (slides here (http://www.openbsd.org/papers/xdc2014-xenocara.pdf)) Jean-Sébastien Pédron, The status of the graphics stack on FreeBSD (https://www.youtube.com/watch?v=POmxFleN3Bc) His presentation gives a history of major changes and outlines the current overall status of graphics in FreeBSD (slides here (http://www.x.org/wiki/Events/XDC2014/XDC2014PedronFreeBSD/XDC-2014_FreeBSD.pdf)) Francois Tigeot, Porting DRM/KMS drivers to DragonFlyBSD (https://www.youtube.com/watch?v=NdM7_yPGFDk) Francois' talk tells the story of how he ported some of the DRM and KMS kernel drivers to DragonFly (slides here (http://www.x.org/wiki/Events/XDC2014/XDC2014TigeotDragonFlyBSD/XDC-2014_Porting_kms_drivers_to_DragonFly.pdf)) *** FreeBSD Quarterly Status Report (https://www.freebsd.org/news/status/report-2014-07-2014-09.html) The FreeBSD project has a report of their activities between July and September of this year Lots of ARM work has been done, and a goal for 11.0 is tier one support for the platform The release includes reports from the cluster admin team, release team, ports team, core team and much more, but we've already covered most of the items on the show If you're interested in seeing what the FreeBSD community has been up to lately, check the full report - it's huge *** Monitoring pfSense logs using ELK (http://elijahpaul.co.uk/monitoring-pfsense-2-1-logs-using-elk-logstash-kibana-elasticsearch/) If you're one of those people who loves the cool graphs and charts that pfSense can produce, this is the post for you ELK (ElasticSearch, Logstash, Kibana) is a group of tools that let you collect, store, search and (most importantly) visualize logs It works with lots of different things that output logs and can be sent to one central server for displaying This post shows you how to set up pfSense to do remote logging to ELK and get some pretty awesome graphs *** Some updates to IPFW (https://svnweb.freebsd.org/base?view=revision&revision=272840) Even though PF gets a lot of attention, a lot of FreeBSD people still love IPFW While mostly a dormant section of the source tree, some updates were recently committed to -CURRENT The commit lists the user-visible changes, performance changes, ABI changes and internal changes It should be merged back to -STABLE after a month or so of testing, and will probably end up in 10.2-RELEASE Also check this blog post (http://blog.cochard.me/2014/10/ipfw-improvement-on-freebsd-current.html) for some more information and fancy graphs *** Interview - Hiroki Sato (佐藤広生) - hrs@freebsd.org (mailto:hrs@freebsd.org) / @hiroki_sato (https://twitter.com/hiroki_sato) BSD in Japan, technology conferences, various topics News Roundup pfSense on Hyper-V (https://virtual-ops.de/?p=600) In case you didn't know, the latest pfSense snapshots support running on Hyper-V Unfortunately, the current stable release is based on an old, unsupported FreeBSD 8.x base, so you have to use the snapshots for now The author of the post tells about his experience running pfSense and gives lots of links to read if you're interested in doing the same He also praises pfSense above other Linux-based solutions for its IPv6 support and high quality code *** OpenBSD as a daily driver (https://www.reddit.com/r/openbsd/comments/2isz24/openbsd_as_a_daily_driver/) A curious Reddit user posts to ask the community about using OpenBSD as an everyday desktop OS The overall consensus is that it works great for that, stays out of your way and is quite reliable Caveats would include there being no Adobe Flash support (though others consider this a blessing..) and it requiring a more hands-on approach to updating If you're considering running OpenBSD as a "daily driver," check all the comments for more information and tips *** Getting PF log statistics (https://secure.ciscodude.net/2014/10/09/firewall-log-stats/) The author of this post runs an OpenBSD box in front of all his VMs at his colocation, and details his experiences with firewall logs He usually investigates any IPs of interest with whois, nslookup, etc. - but this gets repetitive quickly, so.. He sets out to find the best way to gather firewall log statistics After coming across a perl script (http://www.pantz.org/software/pf/pantzpfblockstats.html) to do this, he edited it a bit and is now a happy, lazy admin once again You can try out his updated PF script here (https://github.com/tbaschak/Pantz-PFlog-Stats) *** FlashRD 1.7 released (http://www.nmedia.net/flashrd/) In case anyone's not familiar, flashrd is a tool to create OpenBSD images for embedded hardware devices, executing from a virtualized environment This new version is based on (the currently unreleased) OpenBSD 5.6, and automatically adapts to the number of CPUs you have for building It also includes fixes for 4k drives and lots of various other improvements If you're interested in learning more, take a look at some of the slides and audio from the main developer on the website *** Feedback/Questions Antonio writes in (http://slexy.org/view/s20XvSa4h0) Don writes in (http://slexy.org/view/s20lGUXW3d) Andriy writes in (http://slexy.org/view/s2al5DFIO7) Richard writes in (http://slexy.org/view/s203QoFuWs) Robert writes in (http://slexy.org/view/s29WIplL6k) *** Mailing List Gold Subtle trolling (https://marc.info/?l=openbsd-cvs&m=141271076115386&w=2) Old bugs with old fixes (https://marc.info/?l=openbsd-cvs&m=141275713329601&w=2) A pig reinstall (https://lists.freebsd.org/pipermail/freebsd-ports/2014-October/095906.html) Strange DOS-like environment (https://lists.freebsd.org/pipermail/freebsd-doc/2014-October/024408.html) ***
