Diverse uses: Linux (1)

Article Title: diverse uses to show you a variety of Linux (1 ). Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Linux, as an open operating system, has been welcomed by many users since its publication. Some technical workers perform secondary development on this basis, so there are various versions and usage of Linux. Today, no matter whether your goal is security, storage, music, or even religion, there is a Linux suitable for you. This cannot be called a miracle in the IT world.

Linux adopts an open-source strategy. technical developers can customize a customized Linux, or even operate the Linux kernel. Developers can increase or decrease the components and services of the program as needed.

In addition, because Linux is a free software, some hardware manufacturers will develop pre-installed software packages for PCs or servers as needed to provide them to users. Based on this preinstalled Linux, you can easily create your own user environment or adjust it to a specific application.

With years of development, Linux has become a complete set of categories and a wide variety, including operating system components and various application software. Next we will focus on the Firewall Application Linux-IPCop and m0n0wall; a Linux SAN/NAS device-OpenFiler; two Ubuntu Studio and Musix for music applications; two versions of Ubuntu Linux-the Christian and Muslim editions-are specially optimized for these two categories of users.

IPCop Management Interface

A variety of Linux will make many people dazzled, but this is also the charm of Linux-you can also implement your ideas above.

IPCop

The IPCop firewall system is a branch of SmoothWall LinuX (now called SmoothWall Express). It is based on the Red Hat Linux operating system. However, the latest version of IPCop is based on LFS (Linux From Scratch, Linux ).

In a typical Linux system, the interaction between users and the operating system is either through X-Windows (a window) or through text commands. IPCop is different from the previous method. Once started, IPCop enables the Web server and manages the network through the graphical management interface of the host. When you start IPCop for the first time and enter the management interface, you must configure the topology details of the enterprise intranet protected by IPCop.

IPCop divides the user's network into three color coding areas. The green area is the safest: the green area of IPCop is isolated from other areas by isolation devices. Devices in the green zone must connect to the IPCop server through a hardware network. The next outer ring in the green area protects the blue area, including wireless network devices. The blue-zone isolation device is also implemented by the IPCop firewall system. However, because wireless access is allowed in the area, it has a certain security risk compared with the direct connection of the green area network cable.

The security ring on the outermost layer of IPCop is in the orange area, and the local network of this Part has been exposed to the wider Internet. The orange area is of course a "red" area, which belongs to the outside world. For IPCop, the "red" area is totally out of control. It should be noted that each zone must be connected to an IPCop server through a dedicated Nic. The simplest IPCop system will also have a red zone and a green zone.
