We often need to log on to the Unix/Linux System Using SSH, and use SCP to transmit data. We always need to enter a password. Isn't it annoying?SSH supports multiple login authentication methods. The default mode is keyboard-interactive, that is, the one that manually enters the password. In practical applications, you sometimes need to log on to the SSH server without a password. For example, Mpi jobs need to use SCP to transmit data between WNs (non-interactive mode ). In this case, public key
