name appended with the ". pub" suffix. The program also requires the input of a cipher string (passphrase). Null indicates that there is no cipher language (the cipher language of the host key must be empty ). Passwords are very similar to passwords, but they can be a single sentence, containing words, punctuation marks, numbers, spaces, or any character you want. A good password should contain more than 30 characters, which are hard to guess. it may consist of uppercase/lowercase letters, digi

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
