FAQ

To ensure the highest levels of security, we recommend that remote SSH access not be enabled on the VM instances. 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.

Access VM Instance

We recommend that customers that require this type of access use “Console” access from within vSphere. This approach ensures that access to the VM is only possible by “approved and authenticated” vSphere administrators.

Note

Use the username “rafay_admin” for this type of access.
