With the wide application of Linux operating systems, especially the development of Linux in the embedded field, more and more people are devoted to Linux kernel-level development. Faced with the ever-growing Linux kernel source code, developers will face the same problem after completing their own kernel code, that is
Mago education has been in operation for two years and has trained more than 170 Linux System Engineers. Most of the students who are still in school are employed in Shanghai and Beijing. After time verification, our courses and teaching can closely follow the requirements of Linux O M and
indicating that the process cannot be closed. In this case, the Administrator must terminate the top process and then use the su command to change the account to log on. Then shut down the abnormal process. The system administrator can shut down multiple processes at the same time. The method is simple, that is, enter multiple process numbers to be disabled at the same time. Process numbers must be separated by commas.

As a desktop operating system, Linux's man-machine interface is not flattering. However, as a network operating system, its ease of use (for NOS) and high performance are difficult to find its right. Of course, this does not mean that the operation is very simple, but that if you can master some skills, both system settings and network management can become easy.

Linux has many advantages in terms of functionality, price, and performance. However, as an open operating system, it inevitably has some security risks. This article will tell you how to solve these hidden dangers and provide a secure operation platform for applications.

However, when a vulnerability is revealed, the system administrator is negligent in patching the vulnerability, which can easily cause intrusion. What's worse, hackers can obtain the root shell.
