Create ssh tunnel8/27/2023 ![]() ![]() It’s important to note that SSH tunneling is frequently used by hackers, who build backdoors in internal networks so that attackers can easily access internal data. SSH keys use asymmetric encryption and provide an even higher level of security. SSH port forwarding enables two communicating systems to exchange data securely across the internet and through firewalls. SSH tunnels also offer increased security when you’re surfing on unfamiliar networks, for example in a hotel or coffee shop. Using PuTTY to Create an SSH Tunnel Find putty.exe in the PuTTY folder on your computer, for example, C:Program Files (x86)PuTTY. SSH tunneling, also known as SSH port forwarding, is how SSH tunnels network traffic through application ports from the localhost - the computer physically present - to a remote system or vice versa. ![]() A SSH File Transfer Protocol, SFTP for short, will be used for this. This guide will show you how to make a secure connection to your remote MySQL or MariaDB server from your local computer, using an SSH tunnel. If you’re transporting data from services that use an unencrypted protocol, you can use SSH forwarding to encrypt the data transfer.

How to Set up SSH Tunneling (Port Forwarding) Updated 8 min read SSH tunneling or SSH port forwarding is a method of creating an encrypted SSH connection between a client and a server machine through which services ports can be relayed. This is similar to a Virtual Private Network (VPN) but is nonetheless different - try not to mix the two up. It will look like you are on this network, when you are in reality just accessing it using the SSH tunnel. ![]() The use of this virtual network allows certain restrictions on access to be bypassed. In most cases, SSH port forwarding is used to create an encrypted connection between a local computer (the local host) and a remote computer. In order for the tunnel setup to succeed you must be allowed to connect via ssh as, just as if you had attempted to use ssh to create a terminal. There are various use cases for secure shell port forwarding. Learn how to setup a basic SSH tunnel to access remote server resources that may be blocked by a firewall or simply inaccessible over the internet. ![]()
