Linux network settings 3-ssh tool usage Note 1. ssh tool usage principle ssh (SecureShellClient) is installed on windows, while on linux There is a service called sshd, this service occupies port 22, which is started by default. However, port 22 is not trusted by default and must be set manually. This explains the problems encountered in using ssh. Question 1: windows and linux can be pinged, but the ssh to

access by detecting the host field . There are many websites, such as www.sina.com.cn, www.126.com, and so on. Some Web sites are not restricted to access by IP addresses, but when using IP addresses to access the site, the IP address is relocated to the appropriate domain name. If the input http://141.146.8.66 is relocated to the http://www.oracle.com/index.html, the input http://129.42.60.212 will be relocated to http://www.ibm.com/us/ On The ping command can also get the IP address of a doma

Installation of Linux systems:1.linux System Installation Method three kinds:1. Install the Linux system independently.2. Install the Linux system on the virtual machine.A. Install the virtual machine, basically go all the way down.B. Install Linux.Partitioning is key when C.linux is installed./boot partition 100M./swap swap partition. Typically twice times the physical memory, no more than 256M./root root partition. As large as possible.3. Dual syste

Finally, I will show you a good example based on the above C # network programming knowledge. This instance is a client application using Socket based on synchronization mode. It first establishes an end point by parsing the Server IP address and creates a Socket connection based on Streaming Socket, the protocol used is TCP. Through this Socket, you can send the command to get the web page, use this Socket to get the default web page on the server, a

Before the identity authentication and data encryption and decryption, identity authentication can ensure that the data source is not a problem, data encryption and decryption can ensure that the data is intercepted by eavesdroppers can also prevent eavesdroppers to know the content of the data, to achieve the safe transmission of data, but also to determine the data received without eavesdropping tampering, which involves data integrity check.HashA hash is an irreversible mapping that computes

This chapter describes several mechanisms for user space programs to communicate with the kernel or read kernel information. 1) procfs (/proc)Both procfs and sysctl can export internal kernel information, but procfs is used to export read-only data, while sysctl exports data that can be read and written. Most network functions register one or more files in/proc during initialization. When you read this file, the kernel will call a set of kernel funct
