Connecting to AWS Environments via SSH Using a Port Forwarded Connection

Are you struggling to connect to your AWS environments through a bastion host using an SSH client built into your IDE? If your SSH configuration seems too complex and isn't supported by your tools, don't worry! In this guide, we'll explore how to establish an SSH connection over a port forwarded link, enabling you to connect effortlessly to your desired environments.

Understanding the Challenge

When working in environments like AWS, many organizations employ bastion hosts to enhance security. This means you often have to set up complex SSH configurations to connect to different hosts behind a bastion. Here's an example of what that configuration might look like:

While this setup works great in some SSH clients, others, like CLion, may not support it straightforwardly. So, how can we connect to AWS environments without wrestling with unsupported configurations?

Solution: Setting Up Port Forwarding

Fortunately, we can use a simple solution to get around the restrictions of the IDE. By setting up a port forward using a different SSH client, like PuTTY, you can create a tunnel that later allows you to connect using your IDE. Here’s a step-by-step guide on how to do this:

Step 1: Setting Up Port Forwarding with PuTTY

Download and Install PuTTY: If you haven't already, download PuTTY from its official website and install it on your system.

Launch PuTTY: Open the application after installation.

Configure Your Connection:

In the "Host Name (or IP address)" field, enter your bastion host address (e.g., bastion.*.c1.some.com).

Ensure the port is set to 22 (default SSH port).

Set Up Tunneling:

Navigate to Connection > SSH > Tunnels.

In the "Source port" field, enter a local port number (e.g., 8080) that you want to use for accessing your AWS environments.

In the "Destination" field, enter your final AWS environment address, like *.c1.some.com:22.

Click the "Add" button to add the tunnel configuration.

Connect: Go back to the "Session" section, give your session a name, and click the "Open" button to connect to the bastion host. You'll now have a port forwarded connection established through PuTTY.

Step 2: Connecting from CLion

Open CLion IDE: Launch your IDE where you want to make the SSH connection.

Configure SSH Settings: In the SSH settings of CLion, configure the Host to localhost and the Port to the local port you configured in PuTTY (e.g., 8080).

Enter Credentials: Use the AWS user credentials (awsuser) to log in.

This method should allow you to connect to your AWS environment even though your IDE does not support SSH tunneling natively.

Final Thoughts

The ability to connect to AWS environments through SSH using port forwarding opens up a world of possibilities, especially when integrated with your favorite IDE like CLion. By setting up PuTTY to create a port forward and then connecting through your IDE, you can work seamlessly without compromising security. Remember, this solution is valuable for any SSH client that lacks native tunneling support, so feel free to explore and apply it wherever necessary.

By taking advantage of this SSH workaround, you can continue your development work efficiently and securely. Happy coding!
