Connect to the Cloud Node Using SSH

Connect to the Cloud Node Using SSH

You can connect to your cloud node using SSH to change the default passwords, explore the InterSystems IRIS container, and interact with InterSystems IRIS using the InterSystems Terminal. The way in which you connect depends on the platform you are using, as follows:

• The GCP interface includes a built-in SSH connection option; just click the SSH button for the VM instance on the Compute Engine > VM Instances page. (There are other ways to connect, as described in the GCP documentation, but this is the simplest.)

• Azure uses the credentials you provided for the administrator account on the Create a virtual machine page when deploying the node. To connect using a separate program such as PuTTY, follow the instructions in Instances > Connect to Linux VMs under Virtual machines in AzureOpens in a new tab in the Azure documentation .

• AWS uses the public-private key pair you designated or created when launching the instance, and you must supply the program you use to make an SSH connection with the private key from this pair. You can connect with the popular program PuTTY using these steps:

  1. Open the PuTTYgen key generator program that is installed with PuTTY and do the following:

     1. Use the Load button to load the .pem private key file provided by AWS. (Remember to set the file type selector in the file browser dialog to All files (*.*) to display the .pem file you want to load.)

     2. Use the Save private key button to save the key in .ppk format.

  2. Open the PuTTY program itself and do the following:

     1. In the Host Name box, enter ubuntu@host, where host is either the DNS name or the IP address, for example ubuntu@ec2-34-000-53-213.compute-1.amazonaws.com or ubuntu@34.000.53.213.

     2. In the navigation tree on the left, expand SSH and select Auth, and at the Private key file for authentication prompt browse for the .ppk file you saved in the previous step.

     3. Click Open.

     Once you have successfully connected, you can save the connection settings in PuTTY so that fewer steps will be required to connect in the future.
