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.
Use the username “rafay_admin” for this type of access
Illustrative screenshot below for access to a VM via OpenStack Console.
Although remote access to the VM via SSH is not required, if you would like enable this, follow the steps described below.
This will require you to operate at a degraded security level
Access OpenStack Console¶
Login as rafay_admin via console of VM in Horizon Dashboard
Switch to Root¶
sudo su -
Modify the file "/etc/ssh/sshd_config" to enable password based authentication over ssh.
Update "PasswordAuthentication" from "no" to "yes"
Enable SSH in VM¶
Enable ssh in the VM by typing the following command.
systemctl enable ssh
systemctl start ssh
