Enable SSH access

By default, SSH is disabled on AWS Multi-Tier Solutions. This default configuration can be changed in two ways:

• At the time of deploying the AWS Multi-Tier Solution, ensure that the “SSH Source” field in the “Networking Configuration” section is set to “0.0.0.0/0”. The default setting for the template is set to “127.0.0.¹⁄₃₂” which disables remote SSH access; change this value to enable SSH access to the application server.

  

• Alternatively, after the AWS Multi-Tier Solution is displayed, enable SSH by following these steps:

  • Browse to the AWS CloudFormation dashboard and select the stack for which you wish to enable SSH.

  • From the “Actions” menu, click “Update Stack”.

    

  • You will be prompted to update the stack. Click “Next” until you arrive at the “Specify Details” page.

  • Locate the “Networking Configuration” section on the page and ensure that the “SSH Source” field is set to “0.0.0.0/0”.

    

  • Continue clicking “Next” until you arrive at the final page. Preview your changes and verify that the security group is scheduled for modification.

    

  • Click “Update” to update the stack and enable SSH access to the application server.
