SSH Client checks for the connection on a specific given port and when it receives a connection request, it tunnels the connection to a specific port on a remote SSH server. Local forwarding is the practice of forwarding a port from the client machine(Local SSH Client) to the remote machine(SSH Server) and then the connection is forwarded to another port of the destination machine. SSH Tunneling is also known as SSH Forwarding and it is an easy and effective way of transporting data that use an encrypted protocol(FTP), bypassing firewalls and accessing geographically restricted content.
Apart from the file transmission, SSH Tunneling can also be used to access intranet services across firewalls and to implement VPN. Simply, you can say that it is a tunnel to transfer data from one place to another in a secure way. SSH Tunneling is the way of transmitting unencrypted traffic or data through an encrypted channel.

In our today’s article, we will see how to set up SSH Tunneling and route your traffic securely via SSH tunnels. SSH Tunneling is a practice of creating a secured and encrypted SSH connection between a server machine and a client machine through which data can be transferred and service can be relayed. Therefore, SSH Tunneling is used to transmit data in a fast and secured manner from source to client machine and vice versa. If you are connecting with a different Linux device on a different network then you would have to expose it to the public internet and that may put your system and files at the risk.
