An anonymous reader writes "Today, OpenBSD 5.3 has been released. It has many improvements, updates, and new stuff. Also, OpenSMTPD 5.3 is included. This is the first version of OpenSMTPD considered to be ready for production. Many pre-built packages are available for many architectures. OpenBSD 5.3 ships with various Desktop Environments, including Gnome 3.6, KDE 3.5, and XFCE 4.10." And don't forget the release song, "Blade Swimmer."

    OpenBSD is very cool. It's amazing what Theo and team have done over the years, and sadly, they don't get the cred they so richly deserve: OpenSSH, OpenBGP, pf, etc., and an awesome operating system that just works out of the box.

    I'm very surprised more has not been done with OpenBSD. If I ran a company of any kind, it would be OpenBSD on the servers and Linux on the desktop. I would trust nothing else on my servers. I've worked with OpenBSD professionally and it's a joy to use an easy, well-documented system.

    Kudos to you, Theo!

      Don't forget CARP! []
      • And another little gem - OpenNTPD []. Used on several embedded systems. Works like a charm, unlike the whimsical ntpd, which often simply refuses to do its job.
    • How is PCC coming along? Has the project made much headway in making its break from GCC?

      Why Linux on your desktop if you have OBSD on your servers? You could just as easily go w/ PC-BSD on your desktop/laptops, which would give you a complete BSD environment to work in. But yeah, I'd like to see OBSD be the basis of a firewall/routing OS like pFsense, but w/ IPv6 rather than IPv4 being the focus of expertize.

    Glad to see OpenBSD is continuing to push for better security.

    Has anybody been keeping tabs on performance, particularly on multicore systems? I'm curious what gains have been made there over recent years. I know that Linux and NetBSD have improved a lot, but what about OpenBSD?

    My favorite improvements:

    * OpenSMTPd - can't have too many solid mail servers out there
    * OpenSSH 6.2 - new crypto algorithms and other goodies
    * pf improvements - sloppy state tracking for ICMP
    * relayd and OpenBGPd improvements

    now the question is: how long until those trickle down to sister projects like FreeBSD or Debian/kFreeBSD?

    • Some of this suffers from Good Enough syndrome. Do you really need 5 different mail servers? Is the crypto algorithm underneath SSH the problem with people using SSH?

      Great stuff, and I'm sure its technically slick, but its (potentially) a lot of work to migrate this stuff to another platform, so why do it when there are reasonable alternatives?

    • by Lennie ( 16154 )

      pf improvements ? The last import of pf in OpenBSD was years ago.

      OpenBGPd has a really, really old port and depends on certain kernel interfaces currently only available on OpenBSD (although they could be ported to FreeBSD).

      It will take a long time, I'm afraid. :-(

      • Uh... You *do* realize that pf is OpenBSD native code? That they are constantly hacking on? They wrote it from ground up, why would they be importing *anything*?

        Are you perhaps thinking about Darren Reed's ipf which they cut out years ago, due to Darren's stupid licensing (free and net bsd can change and patch ipf code, but OpenBSD is banned from patching it, nyah nyah).

  • I know software versioning schemes aren't exactly consistent, but isn't 1.0 a tacit milestone for production-ready?
  • Released on May Day, eh? I see what you're up to, OpenBSD. That's a pretty red logo, too.

  • And don't forget the release song, "Blade Swimmer."

    You know that Voight-Kampf test of yours? Did you ever take that test yourself? Theo?

  • by klapaucjusz ( 1167407 ) on Wednesday May 01, 2013 @12:28PM (#43601401) Homepage
    Has anyone checked how correctly OpenSMTPd implements the SMTP protocol? The OpenBSD project has an unfortunate history of caring more about simplicity of implementation than correctness [] (see also this discussion []).
  • Can someone remind me which is the good one? OpenBSD or FreeBSD?
    • by Anonymous Coward

      Both are good. OpenBSD for security, FreeBSD for performance, NetBSD for toasters.

    • And PC-BSD for the Desktop. People seem to forget about that one, you know, the one with easy to install Packages (PBIs).

      • If a PBI is not available in AppCafe one can always use ports w/EasyPBI
      • You think this is unique to PC-BSD? Have you used the others because the summary tells you there are prebuilt binaries for OpenBSD and FreeBSD has packages as well ... As does NetBSD.

        I don't use NetBSD, and I don't use OpenBSD packages, but FreeBSD has had packages for at least 10 years, so since before PC-BSD forked ...

        Why do people bring up this kind of shit as if its not common to all BSDs?

        • PC-BSD ain't a fork of FBSD in the way, that say DragonFly BSD is. It's something that's developed in parallel by a team that's very much a part of the overall FBSD team, except that they are targetted towards desktop usage. So they've focussed on a few things not so important for FBSD, such as the PBI interface. I'd imagine that the next thing they should be working on is Wayland, which is not important for FBSD, but which would be very useful for PC-BSD.
    • that would depend on what you want to do and what you value in a server or desktop or laptop distribution.

      Just for an example, let's take one thing that is BAD about my favorite server distro, OpenBSD. The filesystem is very slow and inflexible compared to ZFS on FreeBSD, no advanced storage operations like clone, grow or snapshot

  • This is a truly fabulous operating system. And for the ones wondering about version numbers, OpenBSD increases it by 0.1 for every release. And a new version is released every 6 months. Also, besides the mailing lists, there is a small but pretty capable community at
