Kylin OS – more details and download links

My last post on Kylin, China’s secure, FreeBSD based operating system, has raised quite a bit of interest and people have been asking for download links.

I’ve done some more research into Kylin, and came across the main Kylin website: (Chinese). The government seems to have set up a company, Kyrin,  to research, develop, promote, educate and deploy Kylin in government departments and commercial enterprices, e.g.

  • China Construction Bank
  • North China Electric Power
  • Xiangcai Securities
  • Shanghai Unicom

Kirin also develops load balancing servers, NAS storage systems,  secure network storage (SecStor) and a Linux based Kylin version.

It’s interesting to note that NeoKylin, or any replacement for Kylin, is developed by China Standard Software and the National University of Defense Technology, and not by Kirin.

What is the reasoning (for the government) to begin developing a new product? Was Kylin with its proprietary security layer not secure enough? Or, is NeoKylin just another domestic Chinese product built with government sponsorship and funding like redflag-linux?

For the record, Kylin 2.1 is Freebsd 5.3 + linux_base-fc4. If you’re familiar with Chinese, you may download Kylin 2.1 from

I’ve not been able to get my fingers on Kylin 3.0 (yet).

    actually i won’t try it due the fact freebsd engine version is too old to support acceptable range of pc desktops/laptops, why they adopted 5.3 version? it’s a 2004 version!

  2. Gerard says

    It’s quite old indeed, but I’m aware of servers still running FreeBSD 4.x. For modern desktop systems you may need something more advanced.

  3. Sean says

    So which is being encouraged for business use?
    Kylin, NeoKylin, Red Flag Linux, or Asianux?
    And are these all being actively developed and updated?

    I’ve not tried any BSD distro yet…
    Am I correct in my understanding that programs written for BSD can’t just be copied over to Linux and recompiled? Or vice versa.

    Western businesses setting up shop in China are NOT going to deploy a BSD or Linux based OS if their corresponding western business apps will not run on those OS’s… on the other hand even if they do run on the BSD or Linux, then any Chinese version of those OS’s need to be up-to-date and compatible with the western equivalents.
