Headlines

FreeBSD 10 as a firewall

  • Back in 2012, the author of this site wrote an article stating you should avoid FreeBSD 9 for a firewall and use OpenBSD instead
  • Now, with the release of 10.0, he's apparently changed his mind and switched back over
  • It mentions the SMP version of pf, general performance advantages and more modern features
  • The author is a regular listener of BSD Now, hi Joe!

Network Noise Reduction Using Free Tools

  • Really long blog post, based on a BSDCan presentation, about fighting spam with OpenBSD
  • Peter Hansteen, author of the book of PF, goes through how he uses OpenBSD's spamd and other security features to combat spam and malware
  • He goes through his experiences with content filtering and disappointment with a certain proprietary vendor
  • Not totally BSD-specific, lots of people can enjoy the article - lots of virus history as well

FreeBSD ASLR patches submitted

  • So far, FreeBSD hasn't had Address Space Layout Randomization
  • ASLR is a nice security feature, see wikipedia for more information
  • With a giant patch from Shawn Webb, it might be integrated into a future version (after a vicious review from the security team of course)
  • We might have Shawn on the show to talk about it, but he's also giving a presentation at BSDCan about his work with ASLR

Old-style pkg_ tools retired

  • At last the old pkg_add tools are being retired in FreeBSD
  • pkgng is a huge improvement, and now portmgr@ thinks it's time to cut the cord on the legacy toolset
  • Ports aren't going away, and probably never will, but for binary package fans and new users that are used to things like apt, pkgng is the way to go
  • All pkg_ tools will be considered unsupported on September 1, 2014 - even on older branches

News Roundup

FreeBSD on OpenStack

  • OpenStack is a cloud computing project
  • It consists of "a series of interrelated projects that control pools of processing, storage, and networking resources throughout a datacenter, able to be managed or provisioned through a web-based dashboard, command-line tools, or a RESTful API."
  • Until now, there wasn't a good way to run a full BSD instance on OpenStack
  • With a project in the vein of Colin Percival's AWS startup scripts, now that's no longer the case!

FOSDEM BSD videos

  • This year's FOSDEM had seven BSD presentations
  • The videos are slowly being uploaded for your viewing pleasure
  • Not all of the BSD ones are up yet, but by the time you're watching this they might be!
  • Check this directory for most of 'em
  • The BSD dev room was full, lots of interest in what's going on from the other communities

The FreeBSD challenge finally returns!

  • Due to prodding from a certain guy of a certain podcast, the "FreeBSD Challenge" series has finally resumed
  • Our friend from the Linux foundation picks up with day 11 and day 12 on his switching from Linux journey
  • This time he outlines the upgrade process of going from 9 to 10, using freebsd-update
  • There's also some notes about different options for upgrading ports and some extra tips

PCBSD weekly digest

  • After the big 10.0 release, the PCBSD crew is focusing on bug fixes for a while
  • During their "fine tuning phase" users are encouraged to submit any and all bugs via the trac system
  • Warden got some fixes and the package manager got some updates as well
  • Huge size reduction in PBI format

Feedback/Questions


  • All the tutorials are posted in their entirety at bsdnow.tv
  • Last week's NTP tutorial got a small update if you're running a LAN-only server, as well as a couple links on how to turn it into a stratum 1 server with a GPS device
  • The SSH tutorial also got some updates
  • Send questions, comments, show ideas/topics, or stories you want mentioned on the show to feedback@bsdnow.tv
  • Watch live Wednesdays at 2:00PM Eastern (19:00 UTC)
