Using OpenSSH Certificate Authentication

  • SSH has a not-so-often-talked-about authentication option in addition to passwords and keys: certificates - you can add certificates to any current authentication method you're using
  • They're not really that complex, there just isn't a lot of documentation on how to use them - this post tries to solve that
  • There's the benefit of not needing a knownhosts file or authorizedusers file anymore
  • The post goes into a fair amount of detail about the differences, advantages and implications of using certificates for authentication

Back to FreeBSD, a new series

  • Similar to the "FreeBSD Challenge" blog series, one of our listeners will be writing about his switching BACK to FreeBSD journey
  • "So, a long time ago, I had a box which was running FreeBSD 4, running on a Pentium. 14 years later, I have decided to get back into FreeBSD, now at FreeBSD 10"
  • He's starting off with PCBSD since it's easy to get working with dual graphics
  • Should be a fun series to follow!

OpenBSD's recent experiments in package building

  • If you'll remember back to our poudriere tutorial, it lets you build FreeBSD binary packages in bulk - OpenBSD's version is called dpb
  • Marc Espie recently got some monster machines in russia to play with to help improve scaling of dpb on high end hardware
  • This article goes through some of his findings and plans for future versions that increase performance
  • We'll be showing a tutorial of dpb on the show in a few weeks

Securing FreeBSD with 2FA

  • So maybe you've set up two-factor authentication with gmail or twitter, but have you done it with your BSD box?
  • This post walks us through the process of locking down an ssh server with 2FA
  • With just a mobile phone and a few extra tools, you can enable two-factor auth on your BSD box and have just that little extra bit of protections

Big changes for OpenBSD 5.6

  • Although 5.5 was just frozen and the release process has started, 5.6 is already looking promising
