A secure system for training OS settings and server construction

高校教师对机房管理人员提出了许多要求。最令人讨厌的是，Windows和Linux环境都是必需的。为了满足这样的要求，广泛使用双引导系统。但在双引导系统上，学生必须等待几分钟才能在Windows和Linux之间切换。管理人员必须重复启动和关闭过程，才能将补丁应用到这两个操作系统。为了同时提供两个操作系统的环境，我们决定使用coLinux作为Windows应用程序运行Linux，并将其安装在我们的PC教室中。与VMware或虚拟PC等完全虚拟化技术相比，CoLinux是一种开源、轻量级的解决方案。Cygwin可能是另一种解决方案，但它对Linux的全部功能有一些限制，比如进程管理。CoLinux使原生Linux应用程序和Windows应用程序都可以在屏幕上同时运行。我们的解决方案还避免了Windows上的Microsoft Office和Linux上的Office Suite之间有时会出现的不兼容问题。

There are many requests from teachers to computer lab management staff in universities. The most annoying one is that both the Windows and Linux environment are required. To satisfy such a request, a dual-boot system is widely used. But on a dual-boot system, students must wait for minutes to switch between Windows and Linux. And management staff has to repeat the boot and shutdown process to apply patches to both operating systems. To provide both operating systems' environment simultaneously, we have decided to use coLinux to run Linux as a Windows application, and installed it in our PC classroom. coLinux, Cooperative Linux, is an open-source, lightweight solution, as compared to full virtualization techniques such as VMware or Virtual PC. Cygwin could be another solution, but it has some restrictions against the full capability of Linux such as process management. coLinux enables both native Linux applications and Windows applications to run simultaneously on the screen. Our solution also avoids incompatibility problems that sometimes occur between Microsoft Office on Windows and Office suites on Linux.
