SSH password-less remote login to Linux host

SSH (Secure Shell) is a security protocol designed for remote login sessions and other network services.

With SSH, You can remotely log on to other Linux Hosts, but you need to enter a password. If you log on to 10.3.93.213, you must enter a password.

To achieve password-less logon, you can use the ssh-keygen command to generate a public key, and then copy the public key to the host to be remotely logged on.

Enter the ssh-keygen command and press enter three times in a row.

Go to the. ssh folder and you will see two files generated:

Id_rsa.pub is the public key. Use the scp command to copy it to the. ssh folder 10.3.93.212.

If the authorized_keys file of 10.3.93.212 already exists, copy id_rsa.pub and run cat id_rsa.pub> authorized_keys.

SSH 10.3.93.212 again. You can log on without a password.
