Since Mac OS is very similar to UNIX-based operating system terminals and Linux, it is not possible to remotely log on to a Linux server without the use of Windows-like putty and CRT tools, requiring a simple 3-step password-free SSH remote.1: Generate the key. Under Mac Terminal, execute the following command:SSH-KEYGEN-T RSAThe default is to press ENTER on the line, do not have to make other changes, afte

The implementation is as follows: If you have two Linux servers A and b,a to implement password-free login b A execute ssh-keygen-t RSA will generate Id_rsa (private key)

that you sent over. If the two keys are the same, the server encrypts the "challenge" with the public key and sends it to the client. After the client receives a "challenge", it decrypts it with its own private key and sends it to the server. The second level does not require a password to be sent over the network compared to the first level.PS: Simply put, the client's public key is placed on the server, then the client can
