Researchers at MIT have turned an innovative open source security technology known as Ksplice into a commercial product.

Ksplice Uptrack, whose general availability was announced today, eliminates the need to reboot Linux servers to perform monthly updates and security patches, the Cambridge, Mass. company said.

ZDnet wrote about the technology in early 2008 based on a tip from Linux Foundation's Ted Ts'o, who saw great promise with the technology.

The subscription service that is based on the MIT technology allows the Linux kernel to be updated live without restarting or disrupting applications: no downtime. This is key because of the frequent updating of the Linux kernel.

Ksplice Uptrack is now available for Red Hat Enterprise Linux, Ubuntu, Debian GNU/Linux, CentOS, Parallels Virtuozzo Containers, and OpenVZ. The subscription fee is 3.95 per month per system after a 30-day free trial. A free version is available for Ubuntu, the company also announced.

"On the coolness scale, this is like changing out a car's engine while speeding down the highway," said Keith Winstein, a business development spokesman for the company.

DreamHost, Media Temple and HostGator are among 40 early adopters of the technology.

Ksplice developer Jeff Arnold, a former MIT graduate student, is Ksplice Inc's CEO. Here's what he said upon the product release today: "Now system administrators can keep their systems up to date without coordinating outages, and they don't need to come in Sunday at 2 a.m. to take everything down," Arnold said in a press release. "They can avoid the biggest headache of server maintenance, with better availability and a smaller window of vulnerability than ever before."

  • Ksplice for Ubuntu

    Thanks! Now it will be a looong time between reboots here! Hadn't realized there was a free version for Ubuntu! Since I don't run a server I hadn't thought that the subscription price was worth it to lose the minimal inconvenience of rebooting for kernel updates!

    • Ksplice is cool but a bit over the top for desktops

      You still need to prepare and plan for the
      patch to happen. You still need to obtain the
      special ksplice prepared patch - it will not
      patch just any change.

      Considering that patches are available from
      Ubuntu by default, rebooting a desktop seems
      far less work that trying to keep it up.

      This is cool technology for single-server based
      operations. If you have a fail-over/cluster you
      can just take down the nodes one after another
      instead of subscribing to ksplice.

      But it sure is cool.

      • I dunno....

        ...[i]maybe[/i] I could see it in an enterprise
        setting since I hate rebooting my desktop. But for
        your home desktop if it requires any hassle at all
        I don't think its worth it. It certainly does ease
        the pain of kernel updates for servers. I can see
        it being pretty big there. But again like you
        said...the price probably wouldn't be worth if for
        clusters.

      • If you think about it...

        Well, if you think about it, it's perfect desktops, netbooks, or always on devices. Updating, patching, or upgrading certain important software while the system is still functioning would be preferable to rebooting constantly between updates. Hell, it would be great if they had a version that worked on any version of Windows.

      @leopards That is really a big question. Google's servers are the heart of Google's business. And it has long been a FEATURE, a FEATURE, not a LOOPHOLE, that one could privately modify the GPL code they use to run their business. Of course web applications are obviously SaaS. But where does one draw the line between those applications and the servers that host them? For example, take an insurance company running open source on their back end servers. At some point they decide to put a customer facing front end on those servers so that customers can access their accounts over the Net. Does that suddenly make that whole kaboodle Saas? If so, I am not sure I am comfortable with AGPL. In fact, I am not sure I am comfortable with this concept anyway since it undercuts one of the few provisions that make GPL software highly attractive to businesses that are not engaged in reselling the software itself. It really compromises the spirit of the GPL in some ways <a href="http://www.kralarabaoyunlari.com/">araba oyunlari</a> <a href="http://www.arabaoyunlarimiz.gen.tr/">araba oyunlari</a>

  • Very cool stuff...

    Someone on the Windows server team - take note - this is the kind of functionality that can give Linux an edge. Keep up with these killer features or expect to lose sales.
