An administrator has deployed an NC2 on AWS cluster and doesn ' t have connectivity...

To SSH into a Controller VM (CVM) in an NC2 on AWS cluster without on-premises connectivity, the administrator needs to ensure that the security settings allow SSH access from the Jump Host. This involves editing the User Management Network Security Group to permit SSH traffic from the Jump Host IP.

Deploy Jump Host:

Ensure the Jump Host is deployed in a public subnet with an Elastic IP (EIP) assigned for external access.

Edit User Management Network Security Group:

Locate the security group associated with the user management network.

Modify the inbound rules to allow SSH (port 22) from the Jump Host ' s IP address. This ensures that the Jump Host can establish an SSH connection to the CVM.

Steps to Edit Security Group:

Navigate to the EC2 dashboard in the AWS Management Console.

Select " Security Groups " under the " Network and Security " section.

Find and select the appropriate security group.

Edit the inbound rules to add a new rule:

Type: SSH

Protocol: TCP

Port Range: 22

Source: Custom IP (enter the Jump Host ' s public IP address)

Additional Configuration:

Ensure that the CVM itself allows SSH connections and that no internal firewall rules block the traffic.
