![]() ![]() Itâs 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. An SSH tunnel is another method of rerouting some or all traffic from one location (like your local computer) through another (your remote server). SSH keys use asymmetric encryption and provide an even higher level of security. This means that if you execute the command below, then navigate to in a browser, you will be able to navigate to the webserver on port 80 through the SSH tunnel. SSH tunnels also offer increased security when youâre surfing on unfamiliar networks, for example in a hotel or coffee shop. The command will create an SSH tunnel on port 22 and route all traffic through this tunnel to the server. A SSH File Transfer Protocol, SFTP for short, will be used for this. If youâre transporting data from services that use an unencrypted protocol, you can use SSH forwarding to encrypt the data transfer. This is similar to a Virtual Private Network (VPN) but is nonetheless different - try not to mix the two up. You'll need to figure out what localport you can use, or you can set it up as 80 and route all HTTP traffic through REMOTE that way (easiest way to get a HTTP proxy when you need it). It will look like you are on this network, when you are in reality just accessing it using the SSH tunnel. 1 Answer Sorted by: 5 Set up a forwarding tunnel: ssh -NL :REMOTE:54000 userTRUSTED then connect to localhost:localport to get to remote:54000.For Destination, enter the destination address and port in the form remoteaddress:remoteport. The use of this virtual network allows certain restrictions on access to be bypassed. To do this in the PuTTY application on Windows, select Connection > SSH > Tunnels. In most cases, SSH port forwarding is used to create an encrypted connection between a local computer (the local host) and a remote computer. There are various use cases for secure shell port forwarding. ![]()
