Public-key-based authentication using SSH 1.x requires an RSA key pair.
The following is an example of generating an RSA key pair with an OpenSSH UNIX client:
% 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
In this example, the identity.pub file is the public-key file that you copy to the storage system root volume.
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
