Public-key-based authentication using SSH 1.x requires an RSA key pair.
Your client generates the RSA key pair, a public key and a private key, and stores them on the client.
The following is an example of generating an RSA key pair with an OpenSSH UNIX client. In the example, the identity.pub file is the public-key file that you copy to the storage system root volume.
% ssh-keygen -t rsa1 -b 1024 Generating public/private rsa1 key pair. Enter file in which to save the key (/u/john/.ssh/identity): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /u/john/.ssh/identity Your public key has been saved in /u/john/.ssh/identity.pub The key fingerprint is: 6a:c7:93:7c:b5:f4:12:87:81:56:5e:a2:62:40:07:8a john@unix1
The following commands append the public key to the /etc/sshd/user_name/.ssh/authorized_keys file on storage system sys1:
% mount sys1:/ /mnt_sys1 % cat identity.pub >> /mnt_sys1/etc/sshd/john/.ssh/authorized_keys
