What is the difference between Linux and Unix?

As Linux quickly replaces the server platform with the Unix,unix veteran, there are a number of differences between Linux and UNIX.

The idea behind any UNIX version is that the vendor provides all the full service to the customer. Software development in a UNIX environment requires proprietary tools to ensure its integrity. Linux philosophy is--everything is open source; The source code for any driver or software component must be open so that users can integrate them optimally.

These two platforms look very similar, but if you don't know the many nuances and definitions between UNIX and Linux, you can create some problems.

UNIX proprietary tools are largely absent from the list of Linux Server software. For example, a UNIX administrator uses EMC's PowerPath tools to connect a redundant Storage Area network (SAN) to a server. On Linux, PowerPath cannot be deployed. The high performance file system and Volume Manager software previously purchased for UNIX servers are licensed and cannot be used on Linux. Does this mean that Linux is an inferior platform? Maybe it's just different from the performance you expect.

The main difference between Linux and Unix is that everything in Linux is open source and therefore free to use. By contrast, paying $ thousands of for software for old servers is always a bad feeling. For PowerPath, for example: all Linux hairstyles have native tools--linux Device Mapper multipath drivers, with the same effects as PowerPath. Even EMC recommends that users use this tool to connect to Linux servers and San devices.

On Linux servers, the volume manager is used to manage storage, which can save expensive licensing fees. Linux comes with a logical Volume manager, which you can use to flexibly configure storage. UNIX administrators should have little problem with the use of these tools, but they still do not believe that free and open source software is as reliable as expensive proprietary solutions.

In some cases, specific proprietary software can also be used on Linux distributions. They are usually matched with purchased hardware. If you have this hardware in your Linux distribution's hardware support list, you will not experience any problems. Linux vendors work with hardware vendors to optimize operations and support. Hardware vendors typically only support enterprise-grade Linux distributions, including SuSE, Oracle, Ubuntu, and Red Hat. Free distributions may encounter situations where hardware is not working well.

UNIX administrators typically use the ifconfig command to monitor the server's network usage. The command also exists on Linux, which was discarded after Kernel 2.0 was released in 1996. Thereafter, the IP command is the only way to monitor the IP situation in the system. This command has many parameter options to facilitate the management and monitoring of the network.

Even if you are an experienced UNIX administrator, consider some technical training so that technology and experience can fill the gap between UNIX and Linux. AC qq:2881064152 Bun
