Enabling key-based access from uvm1 to uvm26

The aadmin@uvm0 user needs to be able to connect via SSH as the aadmin user to uvm26.

Copying the public key to the managed node

Executed:

aadmin@uvm0:~$ ssh-copy-id aadmin@uvm26

Details

    aadmin@uvm0:~$ ssh-copy-id aadmin@uvm26
    /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/aadmin/.ssh/id_ed25519.pub"
    The authenticity of host 'uvm26 (192.168.2.126)' can't be established.
    ED25519 key fingerprint is SHA256:YjaCxj1K8A2Ae7OjsmgvtCzZ27xj/lsakL6veZua3es.
    This key is not known by any other names.
    Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
    /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
    /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
    aadmin@uvm26's password:
 
    Number of key(s) added: 1
 
    Now try logging into the machine, with:   "ssh 'aadmin@uvm26'"
    and check to make sure that only the key(s) you wanted were added.

Testing the key-based access

Executed:

aadmin@uvm0:~$ ssh aadmin@uvm26

Details

    aadmin@uvm0:~$ ssh aadmin@uvm26
