Configure SSH
To configure SSH between two hosts so that a connection does not require a password, perform the
following steps:
1.
Log in to the host that you want to configure as the local host (hereafter, "host 1"). (The second
host serves as the remote host.)
Example
2.
Enter the ssh-keygen -t rsa command to generate a public/private RSA key pair. The CLI prompts
you for a folder in which to store the key.
Example
3.
Press the Enter key to store the key in the default directory (/root/.ssh). The CLI prompts you to
enter a password.
NOTE: Do not enter a password!
Example
4.
Press the Return key to bypass the password option. The CLI prompts you to re-enter the
password.
Example
5.
Press the Return key again (once again, omit a password). The CLI displays the fingerprint of the
host.
