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).
