򐂰 Log in the user account used for remote access to the HMC. Generate the
ssh keys using the ssh-keygen command. In Example 2, we used the root
user account and specified the RSA algorithm for encryption. The security
keys are saved in the /.ssh directory.
Example 2 ssh-keygen output
root@julia/>ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (//.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in //.ssh/id_rsa.
Your public key has been saved in //.ssh/id_rsa.pub.
The key fingerprint is:
72:fb:36:c7:35:4a:20:0d:57:7f:68:ce:d0:33:be:40 root@julia
򐂰 Distribute the public key in file id_rsa.pub to the HMC. In Example 3, we use
the mkauthkeys command to register the key for the hscroot account. The key
will be saved in the file authorized_keys2 on the $HOME/.ssh directory on the
HMC.
