Build and use the Linux development environment-SSH and ssh SSH is short for Secure Shell, developed by the Network Working Group of IETF. SSH is a security protocol built on the application layer and transport layer. SSH is a reliable protocol designed for remote logon ses

About git ssh-key: solves the problem of multiple local ssh-keys, gitssh-keyWhen setting github, the official instructions require that the current id_rsa be backed up and a new private key be generated for github login. If this is done, the new private key cannot continue to log on to the previous machine. This method is a bit violent...Fortunately, ssh allows u

Trivial-do you want to set SSH password-free or ssh-free?

How to use a one-time password to securely log on to Linux through SSH, and use a password to log on to linux through ssh Some people say that security is not a product, but a process. Although the SSH protocol is designed to use encryption technology to ensure security, if improperly used, others can still damage your system, such as weak passwords, key leaks, a

Principle: Key authentication needs to rely on the key, first create a pair of keys (including public keys and keys, and the public key encrypted data can only be decrypted with the key), and put the public key to the need for a remote server. This way, when you log on to a remote server, the client software sends a request to the server requesting authentication with your secret key. After the server receives the request, first in the host directory of the server you look for your public key, a
