List the ten most commonly used Linux commands-general Linux technology-Linux technology and application information. For more information, see the following. Currently, Linux is inseparable from commands, so we still need to learn a little bit about English. In

See include/linux/list.h for all list functionsI copied some functions from include/linux/list.h to my own list.c, and practiced a bit.No other purpose, is to be proficient. After all, a lot of list functions have been tried in the Linux kernel code.The function of

I have just passed the hlist-related functions and macro definitions, and I have done some work here. I hope it will be useful for you to learn about Linux in the future. /* The Linux linked list designer (think that double-ended double-chain tables (next, Prev) are "too wasteful" for hash tables ", therefore, we have designed a set of hlist data structures for

Summary:Based on the list definition of the Linux kernel, this paper attempts to complete the related interface design, and constructs the test case to realize the usage of the list interface.Body:Let's start by looking at the list interfaces provided by the Linux kernel as

Article Title: list of common error reports for Linux email servers. 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. Server 400 Error Report Q: 421 Server too busy A: Unable to conn

As a developer, especially a server application developer, It is very helpful to know a proper amount of common Linux commands. Many daily tasks, such as viewing server logs, Data File Processing, and batch modification, do not need to be implemented using the main development language. Instead, you only need to master and use some commands and tools. However, as developers and system administrators, the degree of learning

Command list for viewing hardware information in LinuxGuideMany commands can be used to view hardware information on Linux systems. Some commands can only print the specific hardware component information such as CPU and memory, and others can view the information of multiple hardware components.This tutorial will show you the most common commands for viewing information about various hardware devices and c

The top ten programmers in the software history, Linux inventor on the list-Linux general technology-Linux technology and application information. The following is a detailed description. No matter how you rank it, Linux inventors can make the

List, numbered 1 ~ The 31 signal is a traditional Unix-supported signal, which is an unreliable signal (non-real-time) numbered 32 ~ The 63 signal was expanded later, called a reliable signal (real-time signal ). The difference between unreliable and reliable signals is that the former does not support queuing and may cause signal loss, while the latter does not. Below we will discuss the signal number smaller than sigrtmin. 1) sighupThis signal is

offNospoof on 3. prevent DoS attacksSetting resource limits for all users of the system can prevent DoS attacks. Such as the maximum number of processes and memory usage.For example, you can add the following lines in/etc/security/limits. conf:* Hard core 0* Hard rss 5000* Hard nproc 20Then, you must edit the/etc/pam. d/login file to check whether the following row exists.Session required/lib/security/pam_limits.soThe preceding command prohibits debugging files. The maximum number of processes

, you can disable Telnet/FTP. To make the change take effect, run the following command:# Killall-HUP inetdBy default, most Linux systems allow all requests, and using TCP_WRAPPERS to enhance system security is a breeze. You can modify/etc/hosts. deny and/etc/hosts. allow to add access restrictions. For example, setting/etc/hosts. deny to "ALL: ALL" can deny ALL access by default. Then add the allowed access to the/etc/hosts. allow file. For example,

This structure is moved from list.h to Types.h, and the core's attention to the circular list is visible.Defined in Include/linux/types.hstruct List_head {struct List_head *next, *prev;};Macros in the Include/linux/list.hInitialize a linked list node named name#define LIST_HEAD_INIT (name) { (name), (name)}#define LIS

IntroducedIt is well known that most of the Linux kernel is written in GNU C language. C is different from other languages, it does not have a good data structure object or standard object library support. So you can borrow the Linux kernel source tree Circular doubly linked list is a very good thing to make people happy.In the Include/

In linux, linuxftp cannot view the file list. After ftp is configured on the linux server today, logon is normal. After ftp is used to log on, all directories can be accessed by manually writing paths, but no data is visible to folders and file lists. Later, I analyzed the cause and found that the result was related to selinux. So after selinux is disabled, I tri

after this operation, you can compile nohup sigtest 3 and shell, the content is as follows: sigtest in fact, any way to turn the process into an orphan process can be done, including fork's immediate termination of the parent process.2. sigchld SignalAfter a sub-process dies, it sends a sigchld signal to the parent process.When a process calls the exit command to end its own life, it is not actually destroyed, but it leaves a data structure called Zombie (the system calls exit, it is used to

Configure the access control list (ACL) of Linux) Using Liunx with permission control is a simple task. It can define the permissions of any user, group, and other. Whether on a desktop computer or without many virtual Linux instances, or when users do not want to share files between them, this is a great job. However, if you are in a large organization, you run
