After you’ve completed the procedure that required passwordless root SSH, you may disable it for all nodes.
- Log in as root on the queen.
Issue the command to disable passwordless SSH, providing the IP address of each worker node in the instance:
# ncli sshkeys disable -n <IP1,IP2,...>
When specifying multiple node IP addresses using the -n option, they must be separated by a comma only, without spaces.
- Whenever you need to re-enable passwordless SSH (for example, when adding a node, upgrading, and so on) the procedure will direct you to do so.
