Secure communications with OpenBSD and OpenVPN

  • Starting off today's theme of encryption...
  • A new blog series about combining OpenBSD and OpenVPN to secure your internet traffic
  • Part 1 covers installing OpenBSD with full disk encryption (which we'll be doing later on in the show)
  • Part 2 covers the initial setup of OpenVPN certificates and keys
  • Parts 3 and 4 are the OpenVPN server and client configuration
  • Part 5 is some updates and closing remarks

FreeBSD Foundation Newsletter

  • The December 2013 semi-annual newsletter was sent out from the foundation
  • In the newsletter you will find the president's letter, articles on the current development projects they sponsor and reports from all the conferences and summits they sponsored
  • The president's letter alone is worth the read, really amazing
  • Really long, with lots of details and stories from the conferences and projects

Use of NetBSD with Marvell Kirkwood Processors

  • Article that gives a brief history of NetBSD and how to use it on an IP-Plug computer
  • The IP-Plug is a "multi-functional mini-server was developed by Promwad engineers by the order of AK-Systems. It is designed for solving a wide range of tasks in IP networks and can perform the functions of a computer or a server. The IP-Plug is powered from a 220V network and has low power consumption, as well as a small size (which can be compared to the size of a mobile phone charger)."
  • Really cool little NetBSD ARM project with lots of graphs, pictures and details

Experimenting with zero-copy network IO

  • Long blog post from Adrian Chadd about zero-copy network IO on FreeBSD
  • Discusses the different OS' implementations and options
  • He's able to get 35 gbit/sec out of 70,000 active TCP sockets, but isn't stopping there
  • Tons of details, check the full post

News Roundup

OpenZFS office hours

  • Our buddy George Wilson sat down to take some ZFS questions from the community
  • You can see more info about it here

License summaries in pkgng

  • A discussion between Justin Sherill and some NYCBUG guys about license frameworks in pkgng
  • Similar to pkgsrc's "ACCEPTABLE_LICENSES" setting, pkgng could let the user decide which software licenses he wants to allow
  • Maybe we could get a "pkg licenses" command to display the license of all installed packages
  • Ok bapt, do it

The FreeBSD challenge continues

  • Checking in with our buddy from the Linux foundation...
  • The switching from Linux to FreeBSD blog series continues for his month-long trial
  • Follow up from last week: "As a matter of fact, I did check out PC-BSD, and wanted the challenge. Call me addicted to pain and suffering, but the pride and accomplishment you feel from diving into FreeBSD is quite rewarding."
  • Since we last mentioned it, he's decided to go from a VM to real hardware, got all of his common software installed, experimented with the Linux emulation, set up virtualbox, learned about slices/partitions/disk management, found BSD alternatives to his regularly-used commands and lots more

Ports gets a stable branch

  • For the first time ever, FreeBSD's ports tree will have a maintained "stable" branch
  • This is similar to how pkgsrc does things, with a rolling release for updated software and stable branch for only security and big fixes
  • All commits to this branch require approval of portmgr, looks like it'll start in 2014Q1


  • All the tutorials are posted in their entirety at
  • Send questions, comments, show ideas/topics, or stories you want mentioned on the show to
  • Watch live Wednesdays at 2:00PM Eastern (19:00 UTC)
  • The end of the year is the best time to donate to the FreeBSD foundation, and they also recently started accepting bitcoin donations
  • The OpenBSD foundation is also accepting bitcoin donations
  • I've been told the NetBSD foundation is working on bitcoin donations, but haven't gotten it going yet
  • Be sure to support the projects you use and love!
