To ensure the highest levels of security, we recommend that remote SSH access not be enabled on the VMs. SSH type of access is not required for any operations performed by administrators. The Controller provides a zero trust, remote diagnostics and control channel that can be leveraged securely as long as
The VM is operational and
The VM has network connectivity to the Controller.
We recommend that customers that require this type of access use “Console” access from within OpenStack Console. This approach ensures that access to the VM is only possible by “approved and authenticated” OpenStack administrators.
Note
Use the username “rafay_admin” for this type of access
