Instructions

  1. Generate key pairs on the Client.
[user@rhel8 ~]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa):  <<<  keep empty
Enter passphrase (empty for no passphrase):                    <<<  keep empty
Enter same passphrase again:                                   <<<  keep empty
Your identification has been saved in /home/user/.ssh/id_rsa.
Your public key has been saved in /home/user/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:eVWNNWLhKu/CUTELDr6K4YwCnD1q1TfZG7MumlGW/JY user@rhel8.peeps.lab

The key's randomart image is:
+---[RSA 3072]----+
|             +o=.|
|       . . oo.o o|
|      . o . =.   |
|      ...o +.    |
|. o .  =S.o.     |
|.o = .o=.*+      |
|. * +.o oE*.     |
|.+ + .o..=.      |
|o    o. o...     |
+----[SHA256]-----+

 

  1. Change to the .ssh directory.
[user@rhel8 ~]$ cd .ssh/

 

  1. Use ls to view the files.
[user@rhel8 .ssh]$ ls
id_rsa  id_rsa.pub  known_hosts

 

  1. Rename the id_rsa.pub to authorized_keys.
[user@rhel8 .ssh]$ mv id_rsa.pub authorized_keys

 

  1. Use ls to view the files.
[user@rhel8 .ssh]$ ls
authorized_keys  id_rsa  known_hosts

 

  1. Use SCP to upload the key to the ".ssh" directory on the Unity.
[user@rhel8 .ssh]$ scp authorized_keys service@XX.XX.XX.XX:/home/service/.ssh
