A must-have for Linux terminals! The secret of driver-free wireless network card
1. Background of Linux driver-free wireless network card In the current era of digital informatization, wireless networks have been integrated into our daily lives and have become an indispensable part. For Linux terminal users, a wireless network card with excellent compatibility and excellent stability is particularly critical. Therefore, the driver-free version of the wireless network card is very popular among users for its convenience, speed and remarkable effects. This kind of driver-free wireless network card not only saves the tedious steps of installing drivers in a Linux system environment, but also brings a better user experience. In the past, although the Linux system provided support for some brands or models of wireless network cards, some network cards still faced driver problems, causing trouble to users. However, thanks to science

Linux stand-alone log audit
1: First check whether sudo and rsyslog services are installed. 2: If the service is not found, you can use yum to install related services. 3: Add content to the /etc/rsylog.conf file. 4: Check the content. After completing the above four steps, stand-alone log auditing is simple. Completed, if someone uses the sudo command to operate, we will check the log file to monitor the operation command and explain: This setting will only monitor when other users use the sudo command, but will not monitor other ordinary operations.

Open source performance appraisal system: innovative performance evaluation, transparent, fair and cost-win-win
1. The concept of open source performance appraisal system. The open source performance appraisal system uses open source technology and community sharing concepts to provide organizations with independent customization and management evaluation process functions, allowing enterprises to make objective, fair and scientific personal performance evaluations. This system not only helps enterprises improve internal management efficiency, but also helps stimulate collaboration and competition among employees, thereby driving further improvements in the performance of the overall organization. In a modern society with highly developed informatization, many companies have discovered the limitations of traditional performance considerations. In this regard, the open source performance appraisal system emerged as an innovative solution strategy. Using open source technology, companies can break through the limitations of the traditional closed management model, improve the sensitivity and efficiency of employee performance evaluation, and ensure a fair evaluation process.

12 common IP commands in the iproute installation package
Year after year, we have been using the ifconfig command to perform network-related tasks, such as checking and configuring network card information. But ifconfig is no longer maintained and has been deprecated in recent versions of Linux! The ifconfig command has been replaced by the ip command. The ip command is somewhat similar to the ifconfig command, but it is much more powerful and has many new functions. The ip command completes many tasks that the ifconfig command cannot. This tutorial will discuss the 12 most common uses of the ip command, so let’s get started. Case 1: Check the network card information. Check the network information such as IP address, subnet and other network card information. Use the ipaddrshow command: [linuxtechi@

Chicken and rabbit in the same cage - detailed explanation of the algorithm
Let’s talk about the importance of algorithms with the help of teacher Kaifu Li: “Algorithms are one of the most important cornerstones in the field of computer science, but they have been ignored by some domestic programmers. Many students have seen that some companies require a variety of programming languages when recruiting. There is a misunderstanding that learning computers means learning various programming languages, or that learning the latest languages, technologies, and standards is the best way to pave the way. In fact, everyone has been misled by these companies. Although programming languages should be learned, But learning computer algorithms and theories is more important, because computer languages and development platforms are changing with each passing day, but what remains the same are those algorithms and theories, such as data structures, algorithms, compilation principles, and computer architecture. , relational database original

How the Linux file system works: Everything in the index node and directory entry is a file
How the Linux file system works Index nodes and directory entries Everything in Linux is a file. Ordinary files, directories, block devices, sockets, and pipes must also be managed through a unified file system. Linux allocates two data structures to each file, an index node and a directory entry, which are mainly used to record the meta-information and directory structure of the file. The index node is the unique identifier of each file. The directory entry maintains the tree structure of the file system. The relationship between the directory entry and the index node is many-to-one. It can be simply understood as: a file can have multiple names. The aliases created for files through hard links will correspond to different directory entries. Such directory entries are essentially still linked to the same file, so their index nodes are the same. The smallest unit of the c drive is a track (512B), however

Common examples of tcpdump
tcpdump is a very commonly used network packet analysis tool that can be used to display TCP/IP and other network data packets transmitted to the system through the network. tcpdump uses the libpcap library to capture network packets. This library is available in almost all Linux/Unix. tcpdump can read the contents from the network card or a previously created packet file, or it can write the packets to a file for subsequent use. You must be root or use sudo privileges to run tcpdump. In this article, we will demonstrate how to use the tcpdump command through some examples, but first let us take a look at how to install tcpdump in various Linux operating systems. Install

The order in which underlying hardware device drivers are inserted into the linked list (driver)
What are drivers: Drivers encapsulate the operations of underlying hardware devices and provide function sockets to the lower layers. Device classification: The Linux system divides devices into three categories: character devices, block devices, and network devices. Character device: refers to a device that can only read and write byte by byte. It cannot randomly read a certain data in the device's video memory. Data must be read in order. Character devices are stream-oriented device Linux driver development. Common character devices include mice, keyboards, serial ports, consoles, and LED devices. Block device: refers to a device that can read a certain thickness of data from any location on the device. Block devices include hard drives, disks, USB flash drives, SD cards, etc. Network device: A network device can be a hardware device, such as a network card; but it can also be a pure
