port forward

ssh -L port:localhost:port username@hostname

ssh -i ~/my-aws-key.pem -N -f -L 8000:localhost:27017 ubuntu@ec2-54-252-168-106.ap-southeast-2.compute.amazonaws.com

• -i ~/my-aws-key.pem specifies the path to the ssh private key file to use for authentication. -N instructs ssh not execute a remote command, so it won't open a remote shell on the server. -f instructs ssh to run in the background. -L 8000:localhost:27017 tells ssh to connect your local (L) port 8000 to the address + port localhost:27017 on the server, in other words to MongoDB running locally on the server. ubuntu@ec2-54-252-168-106.ap-southeast-2.compute.amazonaws.com is the username and address to the AWS EC2 server that I used for testing.
