without a password. The steps are as follows: 1. Execute ssh-keygen-t rsa on each server to generate the key pair:# Ssh-keygen-T RSA 2. After a key pair is generated on each server, copy the public key to the server that requires logon without a password:For example, the three servers 192.168.15.240, 192.168.15.241, a

to encrypt all 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.In addition, this article only disc
