With tunneling enabled, the application contacts to a port on the local host that the SSH client listens on. The SSH connection is used by the application to connect to the application server. This SSH connection is encrypted, protects confidentiality and integrity, and authenticates communicating parties. The secure connection over the untrusted network is established between an SSH client and an SSH server. SSH tunneling enables adding network security to legacy applications that do not natively support encryption. This means that the application data traffic is directed to flow inside an encrypted SSH connection so that it cannot be eavesdropped or intercepted while it is in transit.
It also provides a way to secure the data traffic of any given application using port forwarding, basically tunneling any TCP/IP port over SSH. SSH is a standard for secure remote logins and file transfers over untrusted networks.
It can also be used to implement VPNs (Virtual Private Networks) and access intranet services across firewalls. It can be used to add encryption to legacy applications. SSH tunneling is a powerful tool for securely accessing remote servers and services, and it is widely used in situations where a secure connection is necessary but not available directly.SSH ( Secure Shell ) tunneling is a method of transporting arbitrary networking data over an encrypted SSH connection. For example, you might use an SSH tunnel to securely access a remote network, bypassing a firewall or other security measures.Īlternatively, you might use an SSH tunnel to securely access a local network resource from a remote location, such as a file server or printer. There are many different ways to use SSH tunneling, depending on your needs.

This can be useful for accessing services that are only available on the remote server, or for bypassing restrictions or firewalls that block certain types of traffic. With SSH tunneling, you can redirect traffic from a local port on your computer to a port on a remote server. It can also be used to bypass network restrictions or to securely access services on a network that might not be otherwise secure. SSH tunneling is often used to securely access services that are not directly exposed to the internet, such as a database server or a networked application. It allows a user to connect to a server over an encrypted connection, and then forward traffic from their local machine to the remote server, or vice versa securely over an SSH ( Secure Shell) connection.Īnd also allows you to establish a secure connection between two computers over an insecure network, such as the internet.
SSH tunneling, also known as SSH port forwarding, is a mechanism for creating a secure connection between a local computer and a remote server through which network traffic can be forwarded.
