Playing with sandboxing

• Sandboxing and privilege separation are popular topics these days - they're the goal of the new "shill" scripting language, they're used heavily throughout OpenBSD, and they're gaining traction with the capsicum framework
• This blog post explores capsicum in FreeBSD, some of its history and where it's used in the base system
• They also include some code samples so you can verify that capsicum is actually denying the program access to certain system calls
• Check our interview about capsicum from a while back if you haven't seen it already ***

OpenNTPD on by default

• OpenBSD has enabled ntpd by default in the installer, rather than prompting the user if they want to turn it on
• In nearly every case, you're going to want to have your clock synced via NTP
• With the HTTPS constraints feature also enabled by default, this should keep the time checked and accurate, even against spoofing attacks
• Lots of problems can be traced back to the time on one system or another being wrong, so this will also eliminate some of those cases
• For those who might be curious, they're using the "pool.ntp.org" cluster of addresses and google for HTTPS constraints (but these can be easily changed) ***

FreeBSD workshop in Landshut

• We mentioned a BSD installfest happening in Germany a few weeks back, and the organizer wrote in with a review of the event
• The installfest instead became a "FreeBSD workshop" session, introducing curious new users to some of the flagship features of the OS
• They covered when to use UFS or ZFS, firewall options, the release/stable/current branches and finally how to automate installations with Ansible
• If you're in south Germany and want to give similar introduction talks or Q&A sessions about the other BSDs, get in touch
• We'll hear more from him about how it went in the feedback section today ***

Swap encryption in DragonFly

• Doing full disk encryption is very important, but something that people sometimes overlook is encrypting their swap
• This can actually be more important than the contents of your disks, especially if an unencrypted password or key hits your swap (as it can be recovered quite easily)
• DragonFlyBSD has added a new experimental option to automatically encrypt your swap partition in fstab
• There was another way to do it previously, but this is a lot easier
• You can achieve similar results in FreeBSD by adding ".eli" to the end of the swap device in fstab, there are a few steps to do it in NetBSD and swap in OpenBSD is encrypted by default
• A one-time key will be created and then destroyed in each case, making recovery of the plaintext nearly impossible ***

USB thermometer on OpenBSD

• So maybe you've got BSD on your server or router, maybe NetBSD on a toaster, but have you ever used a thermometer with one?
• This blog post introduces the RDing TEMPer Gold USB thermometer, a small device that can tell the room temperature, and how to get it working on OpenBSD
• Wouldn't you know it, OpenBSD has a native "ugold" driver to support it with the sensors framework
• How useful such a device would be is another story though ***

NAS4Free now on ARM

• We talk a lot about hardware for network-attached storage devices on the show, but ARM doesn't come up a lot
• That might be changing soon, as NAS4Free has just released some ARM builds
• These new (somewhat experimental) images are based on FreeBSD 11-CURRENT
• Included in the announcement is a list of fully-supported and partially-supported hardware that they've tested it with
• If anyone has experience with running a NAS on slightly exotic hardware, write in to us ***

pkgsrcCon 2015 CFP and info

• This year's pkgsrcCon will be in Berlin, Germany on July 4th and 5th
• They're looking for talk proposals and ideas for things you'd like to see
• If you or your company uses pkgsrc, or if you're just interested in NetBSD in general, it would be a good event to check out ***

BSDTalk episode 253

• BSDTalk has released another new episode
• In it, he interviews George Neville-Neil about the 2nd edition of "The Design and Implementation of the FreeBSD Operating System"
• They discuss what's new since the last edition, who the book's target audience is and a lot more
• We're up to 90 episodes now, slowly catching up to Will... ***

FreeBSD quarterly status report

• The FreeBSD team has posted a report of the activities that went on between January and March of this year
• As usual, it's broken down into separate reports from the various teams in the project (ports, kernel, virtualization, etc)
• The ports team continuing battling the flood of PRs, closing quite a lot of them and boasting nearly 7,000 commits this quarter
• The core team and cluster admins dealt with the accidental deletion of the Bugzilla database, and are making plans for an improved backup strategy within the project going forward
• FreeBSD's future release support model was also finalized and published in February, which should be a big improvement for both users and the release team
• Some topics are still being discussed internally, mainly MFCing ZFS ARC responsiveness patches to the 10 branch and deciding whether to maintain or abandon C89 support in the kernel code
• Lots of activity is happening in bhyve, some of which we've covered recently, and a number of improvements were made this quarter
• Clang, LLVM and LLDB have been updated to the 3.6.0 branch in -CURRENT
• Work to get FreeBSD booting natively on the POWER8 CPU architecture is also still in progress, but it does boot in KVM for the time being
• The project to replace forth in the bootloader with lua is in its final stages, and can be used on x86 already
• ASLR work is still being done by the HardenedBSD guys, and their next aim is position-independent executable
• The report also touches on multipath TCP support, the new automounter, opaque ifnet, pkgng updates, secureboot (which should be in 10.2-RELEASE), GNOME and KDE on FreeBSD, PCIe hotplugging, nested kernel support and more
• Also of note: work is going on to make ARM a Tier 1 platform in the upcoming 11.0-RELEASE (and support for more ARM boards is still being added, including ARM64) ***

OpenBSD 5.7 released

• OpenBSD has formally released another new version, complete with the giant changelog we've come to expect
• In the hardware department, 5.7 features many driver improvements and fixes, as well as support for some new things: USB 3.0 controllers, newer Intel and Atheros wireless cards and some additional 10gbit NICs
• If you're using one of the Soekris boards, there's even a new driver to manipulate the GPIO and LEDs on them - this has some fun possibilities
• Some new security improvements include: SipHash being sprinkled in some areas to protect hashing functions, big W^X improvements in the kernel space, static PIE on all architectures, deterministic "random" functions being replaced with strong randomness, and support for remote logging over TLS
• The entire source tree has also been audited to use reallocarray, which unintentionally saved OpenBSD's libc from being vulnerable to earlier attacks affecting other BSDs' implementations
• Being that it's OpenBSD, a number of things have also been removed from the base system: procfs, sendmail, SSLv3 support and loadable kernel modules are all gone now (not to mention the continuing massacre of dead code in LibreSSL)
• Some people seem to be surprised about the removal of loadable modules, but almost nothing utilized them in OpenBSD, so it was really just removing old code that no one used anymore - very different from FreeBSD or Linux in this regard, where kernel modules are used pretty heavily
• BIND and nginx have been taken out, so you'll need to either use the versions in ports or switch to Unbound and the in-base HTTP daemon
• Speaking of httpd, it's gotten a number of new features, and has had time to grow and mature since its initial debut - if you've been considering trying it out, now would be a great time to do so
• This release also includes the latest OpenSSH (with stronger fingerprint types and host key rotation), OpenNTPD (with the HTTPS constraints feature), OpenSMTPD, LibreSSL and mandoc
• Check the errata page for any post-release fixes, and the upgrade guide for specific instructions on updating from 5.6
• Groundwork has also been laid for some major SMP scalability improvements - look forward to those in future releases
• There's a song and artwork to go along with the release as always, and CDs should be arriving within a few days - we'll show some pictures next week
• Consider picking one up to support the project (and it's the only way to get puffy stickers)
• For those of you paying close attention, the banner image for this release just might remind you of a certain special episode of BSD Now... ***

Tor-BSD diversity project

• We've talked about Tor on the show a few times, and specifically about getting more of the network on BSD (Linux has an overwhelming majority right now)
• A new initiative has started to do just that, called the Tor-BSD diversity project
• "Monocultures in nature are dangerous, as vulnerabilities are held in common across a broad spectrum. Diversity means single vulnerabilities are less likely to harm the entire ecosystem. [...] A single kernel vulnerability in GNU/Linux that impacting Tor relays could be devastating. We want to see a stronger Tor network, and we believe one critical ingredient for that is operating system diversity."
• In addition to encouraging people to put up more relays, they're also continuing work on porting the Tor Browser Bundle to BSD, so more desktop users can have easy access to online privacy
• There's an additional progress report for that part specifically, and it looks like most of the work is done now
• Engaging the broader BSD community about Tor and fixing up the official documentation are also both on their todo list
• If you've been considering running a node to help out, there's always our handy tutorial on getting set up ***

PC-BSD 10.1.2-RC1 released

• If you want a sneak peek at the upcoming PC-BSD 10.1.2, the first release candidate is now available to grab
• This quarterly update includes a number of new features, improvements and even some additional utilities
• PersonaCrypt is one of them - it's a new tool for easily migrating encrypted home directories between systems
• A new "stealth mode" option allows for a one-time login, using a blank home directory that gets wiped after use
• Similarly, a new "Tor mode" allows for easy tunneling of all your traffic through the Tor network
• IPFW is now the default firewall, offering improved VIMAGE capabilities
• The life preserver backup tool now allows for bare-metal restores via the install CD
• ISC's NTP daemon has been replaced with OpenNTPD, and OpenSSL has been replaced with LibreSSL
• It also includes the latest Lumina desktop, and there's another post dedicated to that
• Binary packages have also been updated to fresh versions from the ports tree
• More details, including upgrade instructions, can be found in the linked blog post ***

News Roundup

Open Household Router Contraption

• This article introduces OpenHRC, the "Open Household Router Contraption"
• In short, it's a set of bootstrapping scripts to turn a vanilla OpenBSD install into a feature-rich gateway device
• It also makes use of Ansible playbooks for configuration, allowing for a more "mass deployment" type of setup
• Everything is configured via a simple text file, and you end up with a local NTP server, DHCP server, firewall (obviously) and local caching DNS resolver - it even does DNSSEC validation
• All the code is open source and on Github, so you can read through what's actually being changed and put in place
• There's also a video guide to the entire process, if you're more of a visual person ***

OPNsense 15.1.10 released

• Speaking of BSD routers, if you're looking for a "prebuilt and ready to go" option, OPNsense has just released a new version
• 15.1.10 drops some of the legacy patches they inherited from pfSense, aiming to stay closer to the mainline FreeBSD source code
• Going along with this theme, they've redone how they do ports, and are now kept totally in sync with the regular ports tree
• Their binary packages are now signed using the fingerprint-style method, various GUI menus have been rewritten and a number of other bugs were fixed
• NanoBSD-based images are also available now, so you can try it out on hardware with constrained resources as well
• Version 15.1.10.1 was released shortly thereafter, including a hotfix for VLANs ***

IBM Workpad Z50 and NetBSD

• Before the infamous netbook fad came and went, IBM had a handheld PDA device that looked pretty much the same
• Back in 1999, they released the Workpad Z50 with Windows CE, sporting a 131MHz MIPS CPU, 16MB of RAM and a 640x480 display
• You can probably tell where this is going... the article is about installing NetBSD it
• "What prevents me from taking my pristine Workpad z50 to the local electronics recycling facility is NetBSD. With a little effort it is possible to install recent versions of NetBSD on the Workpad z50 and even have XWindows running"
• The author got pkgsrc up and running on it too, and cleverly used distcc to offload the compiling jobs to something a bit more modern
• He's also got a couple videos of the bootup process and running Xorg (neither of which we'd call "speedy" by any stretch of the imagination) ***

FreeBSD from the trenches

• The FreeBSD foundation has a new blog post up in their "from the trenches" series, detailing FreeBSD in some real-world use cases
• In this installment, Glen Barber talks about how he sets up all his laptops with ZFS and GELI
• While the installer allows for an automatic ZFS layout, Glen notes that it's not a one-size-fits-all thing, and goes through doing everything manually
• Each command is explained, and he walks you through the process of doing an encrypted installation on your root zpool ***

Broadwell in DragonFly

• DragonFlyBSD has officially won the race to get an Intel Broadwell graphics driver
• Their i915 driver has been brought up to speed with Linux 3.14's, adding not only Broadwell support, but many other bugfixes for other cards too
• It's planned for commit to the main tree very soon, but you can test it out with a git branch for the time being ***

Strange timer bug in FreeBSD 11

• Peter Wemm 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, offering a different patch to fix the issue and detect it early 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

• 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

• DragonFlyBSD, along with PCBSD and EdgeBSD, uses git as its version control system for the system source code
• In a series of posts, 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?

• 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 / @henningbrauer

OpenNTPD and its portable variant

News Roundup

Authenticated time in OpenNTPD

• 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 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 and Theo 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

• 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, 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

• A common question we get about our poudriere tutorial 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

• 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

• 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, giving a bit of interesting backstory
• According to Antti Kantee, "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

• 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 ***

Introducing OPNsense, a pfSense fork

• OPNsense is a new BSD-based firewall project that was recently started, forked from the pfSense codebase
• Even though it's just been announced, they already have a formal release based on FreeBSD 10 (pfSense's latest stable release is based on 8.3)
• The core team includes a well-known DragonFlyBSD developer
• You can check out their code on Github now, or download an image and try it out - let us know if you do and what you think about it
• They also have a nice wiki and some instructions on getting started for new users
• We plan on having them on the show next week to learn a bit more about how the project got started and why you might want to use it - stay tuned ***

Code rot and why I chose OpenBSD

• Here we have a blog post about rotting codebases - a core banking system in this example
• The author tells the story of how his last days spent at the job were mostly removing old, dead code from a giant project
• He goes on to compare it to OpenSSL and the hearbleed disaster, from which LibreSSL was born
• Instead of just bikeshedding like the rest of the internet, OpenBSD "silently started putting the beast into shape" as he puts it
• The article continues on to mention OpenBSD's code review process, and how it catches any bugs so we don't have more heartbleeds
• "In OpenBSD you are encouraged to run current and the whole team tries its best to make current as stable as it can. You know why? They eat their own dog food. That's so simple yet so amazing that it blows my mind. Developers actually run OpenBSD on their machines daily."
• It's a very long and detailed story about how the author has gotten more involved with BSD, learned from the mailing lists and even started contributing back - he says "In summary, I'm learning more than ever - computing is fun again"
• Look for the phrase "Getting Started" in the blog post for a nice little gem ***

ZFS vs HAMMER FS

• One of the topics we've seen come up from time to time is how FreeBSD's ZFS and DragonFly's HAMMER FS compare to each other
• They both have a lot of features that traditional filesystems lack
• A forum thread was opened for discussion about them both and what they're typically used for
• It compares resource requirements, ideal hardware and pros/cons of each
• Hopefully someone will do another new comparison when HAMMER 2 is finished
• This is not to be confused with the other "hammer" filesystem ***

Portable OpenNTPD revived

• With ISC's NTPd having so many security vulnerabilities recently, people need an alternative NTP daemon
• OpenBSD has developed OpenNTPD since 2004, but the portable version for other operating systems hasn't been actively maintained in a few years
• The older version still works fine, and is in FreeBSD ports and NetBSD pkgsrc, but it would be nice to have some of the newer features and fixes from the native version
• Brent Cook, who we've had on the show before to talk about LibreSSL, decided it was time to fix this
• While looking through the code, he also found some fixes for the native version as well
• You can grab it from Github now, or just wait for the updated release to hit the repos of your OS of choice ***

Interview - Ian Sutton - ian@kremlin.cc

BSD replacements for systemd dependencies

News Roundup

pkgng adds OS X support

• FreeBSD's next-gen package manager has just added support for Mac OS X
• Why would you want that? Well.. we don't really know, but it's cool
• The author of the patch may have some insight about what his goal is though
• This could open up the door for a cross-platform pkgng solution, similar to NetBSD's pkgsrc
• There's also the possibility of pkgng being used as a packaging format for MacPorts in the future
• While we're on the topic of pkgng, you can also watch bapt's latest presentation about it from ruBSD 2014 - "four years of pkg" ***

Secure secure shell

• Almost everyone watching BSD Now probably uses OpenSSH and has set up a server at one point or another
• This guide provides a list of best practices beyond the typical "disable root login and use keys" advice you'll often hear
• It specifically goes in-depth with server and client configuration with the best key types, KEX methods and encryption ciphers to use
• There are also good explanations for all the choices, based both on history and probability
• Minimal backwards compatibility is kept, but most of the old and insecure stuff gets disabled
• We've also got a handy chart to show which SSH implementations support which ciphers, in case you need to support Windows users or people who use weird clients ***

Dissecting OpenBSD's divert(4)

• PF has a cool feature that not a lot of people seem to know about: divert
• It lets you send packets to userspace, allowing you to inspect them a lot easier
• This blog post, the first in a series, details all the cool things you can do with divert and how to use it
• A very common example is with intrusion detection systems like Snort ***

Screen recording on FreeBSD

• This is a neat article about a topic we don't cover very often: making video content on BSD
• In the post, you'll learn how to make screencasts with FreeBSD, using kdenlive and ffmpeg
• There are also notes about getting a USB microphone working, so you can do commentary on whatever you're showing
• It also includes lots of details and helpful screenshots throughout the process
• You should make cool screencasts and send them to us ***

• The "bsdconferences" YouTube channel has quite a lot of interesting older BSD talks too - you may want to go back and watch them if you haven't already ***

OpenBSD PIE enhancements

• ASLR and PIE 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
• With this and a few related commits, 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 if you want to get a slice of the action now ***

FreeBSD foundation semi-annual newsletter

• 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'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 BSD you use, it really can make a difference ***

Modernizing OpenSSH fingerprints

• 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, 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 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 ***

Plans for the BSDCan 2015 conference

News Roundup

Introducing ntimed, a new NTP daemon

• As we've mentioned before in our tutorials, 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 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 or on Github
• PHK also has a few blog entries about the project, including status updates ***

OpenBSD-maintained projects list

• There was recently a read on the misc mailing list 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

• 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

• This is a blog post about OpenBSD's 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, or use it with FreeBSD or NetBSD via ports and pkgsrc
• You might also want to go back and listen to BSDTalk episode 68, where Will talks to Bob Beck about spamd ***

Crazed Ferrets in a Berkeley Shower

• In 2000, MWL wrote an essay for linux.com about why he uses the BSD license: "It’s actually stood up fairly well to the test of time, but it’s fourteen years old now."
• This is basically an updated version about why he uses the BSD license, in response to recent comments from Richard Stallman
• Very nice post that gives some history about Berkeley, the basics of the BSD-style licenses and their contrast to the GNU GPL
• Check out the full post if you're one of those people that gets into license arguments
• The takeaway is "BSD is about making the world a better place. For everyone." ***
