FreeBSD 10.1-BETA1 is out

• The first maintenance update in the 10.x series of FreeBSD is on its way
• Since we can’t see a changelog yet, the 10-STABLE release notes offer a glimpse at some of the new features and fixes that will be included in 10.1
• The vt driver was merged from -CURRENT, lots of drivers were updated, lots of bugs were fixed and bhyve also got many improvements from 11
• Initial UEFI support, multithreaded softupdates for UFS and many more things were added
• You can check the release schedule for the planned release dates
• Details for the various forms of release media can be found in the announcement

Remote headless OpenBSD installation

• A lot of server providers only offer a limited number of operating systems to be easily installed on their boxes
• Sometimes you’ll get lucky and they’ll offer FreeBSD, but it’s much harder to find ones that natively support other BSDs
• This article shows how you can use a Linux-based rescue system, a RAM disk and QEMU to install OpenBSD on the bare metal of a server, headlessly and remotely
• It required a few specific steps you’ll want to take note of, but is extremely useful for those pesky hosting providers

Building a firewall appliance with pfSense

• In this article, we learn how to easily set up a gateway and wireless access point with pfSense on a Netgate ALIX2C3 APU
• After the author’s modem died, he decided to look into a more do-it-yourself option with pf and a tiny router board
• The hardware he used has gigabit ports and a BSD-compatible wireless card, as well as enough CPU power for a modest workload and a few services (OpenVPN, etc.)
• There’s a lot of great pictures of the hardware and detailed screenshots, definitely worth a look

Receive Side Scaling – UDP testing

• Adrian Chadd has been working on RSS (Receive Side Scaling) in FreeBSD, and gives an update on the progress
• He’s using some quad core boxes with 10 gigabit ethernet for the tests
• The post gives lots of stats and results from his network benchmark, as well as some interesting workarounds he had to do
• He also provides some system configuration options, sysctl knobs, etc. (if you want to try it out)
• And speaking of Adrian Chadd…

BSD on laptops, wifi, drivers, various topics

News Roundup

Sendmail removed from OpenBSD

• Mail server admins around the world are rejoicing, because sendmail is finally gone from OpenBSD
• With OpenSMTPD being a part of the base system, sendmail became largely redundant and unneeded
• If you’ve ever compared a “sendmail.cf” file to an “smtpd.conf” file… the different is as clear as night and day
• 5.6 will serve as a transitional release, including both sendmail and OpenSMTPD, but 5.7 will be the first release without it
• If you still need it for some reason, sendmail will live in ports from now on
• Hopefully FreeBSD will follow suit sometime in the future as well, possibly including DragonFly’s mail transfer agent in base (instead of an entire mail server)

pfSense backups with pfmb

• We’ve mentioned the need for a tool to back up pfSense configs a number of times on the show
• This script, hosted on github, does pretty much exactly that
• It can connect to one (or more!) pfSense installations and back up the configuration
• You can roll back or replace failed hardware very easily with its restore function
• Everything is done over SSH, so it should be pretty secure

The Design and Implementation of the FreeBSD Operating System

• We mentioned when the pre orders were up, but now “The Design and Implementation of the FreeBSD Operating System, 2nd edition” seems to be shipping out
• If you’re interested in FreeBSD development, or learning about the operating system internals, this is a great book to buy
• We’ve even had all three authors on the show before!

OpenBSD’s systemd replacement updates

• We mentioned last week that the news of OpenBSD creating systemd wrappers was getting mainstream attention
• One of the developers writes in to Undeadly, detailing what’s going on and what the overall status is
• He also clears up any confusion about “porting systemd to BSD” (that’s not what’s going on) or his code ever ending up in base (it won’t)
• The top comment as of right now is a Linux user asking if his systemd wrappers can be ported back to Linux… poor guy

• Last week we mentioned that Ken was looking for help to port Lumina to other BSDs, and now it’s been done for OpenBSD and DragonFly – so now you can try it out there too
• Antoine Jacoutot sent a screenshot of Lumina on OpenBSD
• We’ll be at EuroBSDCon soon, so there will be a prerecorded episode next week
• When we’re not in Europe, you can usually watch live Wednesdays at 2:00PM Eastern (18:00 UTC)

The post The Promised WLAN | BSD Now 55 first appeared on Jupiter Broadcasting.

We’ll be showing you how to set up a secure, SSL-only webserver. There’s also an interview with Eric Le Blan about community participation and FreeBSD’s role in the commercial server space. All that and more, on BSD Now – the place to B.. SD.

Headlines

Password gropers take spamtrap bait

• Our friend Peter Hansteen, who keeps his eyes glued to his log files, has a new blog post
• He seems to have discovered another new weird phenomenon in his pop3 logs
• “yes, I still run one, for the same bad reasons more than a third of my readers probably do: inertia”
• Someone tried to log in to his service with an address that was known to be invalid
• The rest of the post goes into detail about his theory of why someone would use a list of invalid addresses for this purpose

Inside the Atheros wifi chipset

• Adrian Chadd – sometimes known in the FreeBSD community as “the wireless guy” – gave a talk at the Defcon Wireless Village 2014
• He covers a lot of topics on wifi, specifically on Atheros chips and why they’re so popular for open source development
• There’s a lot of great information in the presentation, including cool (and evil) things you can do with wireless cards
• Very technical talk; some parts might go over your head if you’re not a driver developer
• The raw video file is also available to download on archive.org
• Adrian has also recently worked on getting Kismet and Aircrack-NG to work better with FreeBSD, including packet injection and other fun things

Trip report and hackathon mini- roundup

• A few more (late) reports from BSDCan and the latest OpenBSD hackathon have been posted
• Mark Linimon mentions some of the future plans for FreeBSD’s release engineering and ports
• Bapt also has a BSDCan report detailing his work on ports and packages
• Antoine Jacoutot writes about his work at the most recent hackathon, working with rc configuration and a new /etc/examples layout
• Peter Hessler, a latecomer to the hackathon, details his experience too, hacking on the installer and built-in upgrade function
• Christian Weisgerber talks about starting some initial improvements of OpenBSD’s ports infrastructure

DragonFly BSD 3.8.2 released

• Although it was already branched, the release media is now available for DragonFly 3.8.2

News Roundup

Defend your network and privacy, FreeBSD version

• Back in episode 39, we covered a blog post about creating an OpenBSD gateway – partly based on our router tutorial
• This is a follow-up post, by the same author, about doing a similar thing with FreeBSD
• He mentions some of the advantages and disadvantages between the two operating systems, and encourages users to decide for themselves which one suits their needs
• The rest is pretty much the same things: firewall, VPN, DHCP server, DNSCrypt, etc.

Don’t encrypt all the things

• Another couple of interesting blog posts from Ted Unangst about encryption
• It talks about how Google recently started ranking sites with HTTPS higher in their search results, and then reflects on how sometimes encryption does more harm than good
• After heartbleed, the ones who might be able to decrypt your emails went from just a three-letter agency to any script kiddie
• He also talks a bit about some PGP weaknesses and a possible future replacement
• He also has another, similar post entitled “in defense of opportunistic encryption“

New automounter lands in FreeBSD

• The work on the new automounter has just landed in 11-CURRENT
• With help from the FreeBSD Foundation, we’ll have a new “autofs” kernel option
• Check the SVN viewer online to read over the man pages if you’re not running -CURRENT
• You can also read a bit about it in the recent newsletter

OpenSSH 6.7 CFT

• It’s been a little while since the last OpenSSH release, but 6.7 is almost ready
• Our friend Damien Miller issued a call for testing for the upcoming version, which includes a fair amount of new features
• It includes some old code removal, some new features and some internal reworkings – we’ll cover the full list in detail when it’s released
• This version also officially supports being built with LibreSSL now
• Help test it out and report any findings, especially if you have access to something a little more exotic than just a BSD system
