OpenBSD automatic installation

  • A CFT (call for testing) was posted for OpenBSD’s new automatic installer process
  • Using this new system, you can spin up fully-configured OpenBSD installs very quickly
  • Allows you to PXE boot the system and load the answer file via HTTP by each machines MAC address, with fallback to a default config file
  • It will answer all the questions for you and can put files into place and start services
  • Great for large deployments, help test it and report your findings

FreeNAS install guide and blog posts

  • A multipart series on YouTube about installing FreeNAS
  • In part 1, the guy (who is possibly Dracula, with his very Transylvanian accent..) builds his new file server and shows off the hardware
  • In part 2, he shows how to install and configure FreeNAS, uses IPMI, sets up his pools
  • He pronounces gigabytes as jiggabytes and it’s hilarious
  • We’ve also got an unrelated blog post about a very satisfied FreeNAS user who details his setup
  • As well as another blog post from our old pal Devin Teske about his recent foray into the FreeNAS development world

FreeBSD 10.0-RC5 is out

  • Another, unexpected RC is out for 10.0
  • Includes an ABI change, you must recompile/reinstall all ports/packages if you are upgrading from a previous 10.0-RC
  • Minor fixes included, please help test and report any bugs
  • You can update via freebsd-update or from source
  • Hopefully this will be the last one before 10.0-RELEASE, which has tons of new features we’ll talk about
  • It’s been tagged -RELEASE in SVN already too!

OpenBSD 5.5-beta is out

  • Theo updated the branch status to 5.5-beta
  • A list of changes is available
  • Help test and report any bugs you find
  • Lots of rapid development with signify (which we mentioned last week), the beta includes some “test keys”
  • Does that mean it’ll be part of the final release? We’ll find out in May.. or when we interview Ted (soon)

iXsystems - Enterprise Servers and Storage For Open Source

iX doesn’t just make big servers for work, they also make little servers for home. The FreeNAS Mini is a compact little rig that will take up to 4 drives and makes a great home storage server.

BHyVe – the BSD hypervisor
+ Could you tell us a bit about yourselves and how you first got into BSD?
+ What’s your current roles in the FreeBSD project, and how did you get there?
+ What exactly is bhyve and how did the project get started?
+ What is the current status of bhyve? What guest OSes are supported?
+ What bugs remain when running different guest OSs?
+ How is support for AMD hardware virtualization progressing?
+ Is there any work on supporting older hardware that does not have EPT?
+ What will it take to be able to boot FreeBSD root-on-zfs inside bhyve?
+ Any progress on a ‘vfs hack’ to mount/passthru a file system (zfs dataset?) from the host to the guest, a la Jails?
+ How is the performance? How does the network performance compare to alternatives? How much benchmarking has been done?
+ What features have been added recently? (nmdm etc)
+ When is VGA support planned?
+ When might we see Windows (server) as a guest? What else would be required to make that happen?
+ What features are you planning for the future? How far do you plan to take bhyve (snapshots, live migration etc)

News Roundup

Hostname canonicalisation in OpenSSH

  • Blog post from our friend Damien Miller
  • This new feature allows clients to canonicalize unqualified domain names
  • SSH will know if you typed “ssh bsdnow” you meant “ssh” with new config options
