Often in the Linux between the SCP command transmission files, each time the need to enter the other machine password, very troublesome. This approach allows both parties to automatically pass the key authentication without having to enter the password manually:

login information and become a basic solution for Internet security, which has become a standard configuration for Linux systems.It should be noted that SSH is only a protocol, there are many implementations, both commercial and open source implementation. The implementation of this article is OpenSSH, it is free software, the application is very extensive.Encrypting all transmitted data so that the "man-in-the-middle" attack is not possible, and it

You can select either of them. Next StepYou can enter a password here (the password is required for Logon), or leave it blank.This is the password length. The default value is 1024. Next StepCreating a secret.Note that the se

Recently, a project needs to use a server as a dedicated deployment server, encountered some problems in the implementation process, as follows:1. The SSH default port of the server and the SSH port of the project Git repository are inconsistent 2. Deployment requires SSH key provided by the project and cannot use the
expected that more and more people will use it instead of SSH in the future.
SSH is composed of the client and server software. There are two incompatible versions: 1.x and 2.x. The client program using SSH 2.x cannot connect to the service program of SSH 1.x. OpenSSH 2.x supports both
Ps: how to change the SSH port in Ubuntu

Port 22 // The default ssh Port is 22.Port 25680 // change the Port number to 25680Ps: when changing a service port, it is best not to delete the original port number to avoid affecting others' use. Add a port first. After th

This error occurs because when you add a new key on GitHub, the ~/.ssh/id_rsa.pub content is copied incorrectly. Generally occurs under Linux, because Windows uses notepa++ to open this file and copy is generally not a problem, and Linux under the use of Vim to open and copy will be added to vim because of the addition of the key to add failure. The workaround is
