You can use SSH tunnels for any type of traffic. Using telnet to connect to a remote server, and routing the traffic through SSH for securityĪs you can see, we now have a telnet session opened to the remote server, but it’s a secured connection since it is being sent through the existing SSH tunnel that we established in the other terminal. – The remote server IP or domain name.Īt this point, every connection which uses port 4500 on the localhost will be redirected to remote port 23.user – The username to login to SSH on the remote server.23 – The remote port that we are trying to connect to.127.0.0.1 – This is our local system’s loopback address.4500 – The port on our local system which we will send traffic through.-L – This option tells SSH that we want to create a tunnel through port forwarding.$ ssh -L 4500:127.0.0.1:23 dissect what’s going on in this command. Keep in mind that a tunnel is erected only when the SSH connection is running. Since we are using a port higher than 1024, an ordinary user is able to create this port forward connection.

As an example, we will forward port 4500 on our local system to port 23 (telnet) on a remote system. SSH port forwarding works by forwarding traffic from a specific port on your local system to a port on the remote system. This will secure the protocol and make it safe to use. As an example, we’ll create port forwarding for the telnet protocol, which is usually avoided because of how it transfers data in clear text.

In this guide, we’ll go over the step by step instructions to show you how to use SSH port forwarding to create a secure tunnel for some other application. By principle, it works very similarly to a VPN. This is accomplished by creating a secure tunnel and then routing another protocol’s traffic through that tunnel. SSH port forwarding can be used to encrypt the traffic between two systems for pretty much any protocol. But the encrypted tunnels it creates are actually quite versatile and can be used for more than just remote server management or file transfer. SSH is known as a very secure protocol because it encrypts traffic end to end.

It’s also commonly used for SFTP to download or upload files. Most Linux users are familiar with the SSH protocol as it allows remote management of any Linux system.
