How to Setup SSH Tunneling To Access AWS EC2
What is SSH Tunneling?
SSH tunneling, also known as SSH port forwarding, is a way to create a secure connection between a local computer and a remote server through an SSH protocol. This can be useful for securely accessing resources on a remote server, such as a database or web service, from a local machine.
How to use SSH Tunneling on AWS EC2?
On AWS, you can create an SSH tunnel to a remote server by using the "ssh" command on your local machine, followed by the appropriate options and the remote server's IP address or hostname.
For example, to create an SSH tunnel to a remote server with an IP address of "1.2.3.4", you could use the following command:
ssh -L local_port:remote_host:remote_port ec2-user@1.2.3.4
This command tells SSH to forward connections made to the local machine on "local_port" to the remote host on "remote_port".
You can also specify additional options like the key pair to use to connect to the ec2 instance and the identity file.
ssh -i "path/to/key.pem" -L local_port:remote_host:remote_port ec2-user@1.2.3.4
It is a good practice to use a security group to allow only your IP address to connect to your ec2 instance and the port number you are forwarding.
