Open a second local terminal and use nc to catch the data: nc localhost 5678 > local_copy.txt Use code with caution. 2. Using Amazon S3 as a Proxy (Most Common)
Run this in your local terminal using the AWS CLI Session Manager plugin : aws session manager download file locally
If you have S3 access, this is often the most reliable way to move large files or multiple directories. Open a second local terminal and use nc
aws ssm start-session --target i-0123456789abcdef0 \ --document-name AWS-StartPortForwardingSession \ --parameters '{"portNumber":["5678"],"localPortNumber":["5678"]}' Use code with caution. While AWS Session Manager does not have a
This method allows you to transfer files directly through an SSM tunnel without needing an S3 bucket or open SSH ports.
To , you can use several methods depending on your security requirements and available tools. While AWS Session Manager does not have a native cp command, you can achieve file transfers via port forwarding , S3 proxying , or AWS CLI integration . 1. Port Forwarding with Netcat (Native SSM)
Use netcat to pipe the file to a specific port (e.g., 5678): nc -l 5678 < /path/to/remote_file.txt Use code with caution.
