After you ping someone else's IPv6 URL, you can confirm that the LAN does not support IPv6. Therefore, we need to use tunneling technology to establish an IPv6 connection between two machines. 1. No IPv6 address is found on the testing server.

Vsftpd is one of the FTP server software on Linux. It supports many options, one of which allows OpenSSL to encrypt data, to some extent, this can make up for the defects of the inscription transmitted when ftp transfers the account password

Memory usage can be said to be extremely important to programmers, especially in large-scale data processing, how to reach the maximum memory bandwidth is the goal pursued by programmers. Starting from this section, we will discuss through a series

There are various versions of the sysctl. conf optimization solution on the Internet, most of which are copied and copied, making new users confused. To solve this problem, after two days of sorting and checking n more data, we will summarize the

Some people say that Linux does not have open office or libre office? Yes, but when we put DOC files or ppt files in Windows on libreoffice, we obviously can see that the format is completely different! All typographical la s are invalid! Therefore,

1. What is socket? A socket can be considered as a programming interface between a user process and the kernel network protocol stack.Socket can be used not only for inter-process communication on the local machine, but also for inter-process

I. Theoretical Basis The red/black tree is a binary search tree with a color attribute on each node. The color is red or black. In addition to the mandatory requirements for binary tree search, the following additional requirements are added for any

In the traditional UNIX model, when a process needs to be executed by another entity, the process derives (fork) A sub-process for processing. In UNIX, most network server programs are written in this way. That is, the parent process accepts

The author Email: zhh@httc.cn introduces the application of Linux in the embedded field, the development mode of host machine and target machine, and gives the realization process of the kernel in detail. This paper analyzes the structure of glibc

This section describes not only process viewing, but also what other users are doing because Linux is a multi-user system, therefore, this section also involves multiple users. At the same time, Linux is a multi-process system that often requires

Preface In the last few months, I have made a rough research on Linux kernel. Next I need to perform in-depth and detailed analysis. It mainly uses a Development Board of S3C2440 as the hardware entity. It includes the following content: 1
