Once the tunnel is in place, fire up your favorite VNC client and point it to 127.0.0.1 or localhost on port 59001: I’ll show an example of what options you need to select inside the Putty connection later. Here are some enlarged views so you can see what’s going on. This is a visual example of what the connection looks like: The one thing I will say is make sure you use a password when you start it up. I won’t go into how to set up a VNC Server on linux as there are plenty of tutorials out there that will cover it. I will then open a tunnel to another machine inside the remote network that will establish a connection to the VNC server running on that machine. In this scenario, I will be using my laptop at home to connect into a landing pad UNIX machine at work. Anyway- SSH tunnels can be a bit confusing to the lay person so I thought I’d do a graphical illustration to help that out. It’s just that a majority of my work is done from a windows machine and I refuse to install the bloated CYGWIN app on my machine just to get an ssh command line session. You aren’t limited to doing this with PuTTY or VNC. What if you need to be on the GUI console of the target machine inside the firewall and the firewall doesn’t allow the port you need to use?Įnter VNC and PuTTY. That’s all fine and dandy if you don’t need a GUI. Normally I just ssh in and then jump to the machine I need to be on. The general connection scheme is shown below.From time to time I have a need to connect to a system inside another remote network (usually my work).

In this example, we will create a local Port 8888, and the connection to it will be forwarded to the RDP port 3389 on a remote Windows computer. All connections to this port are forwarded to the specified port on a remote server via the SSH tunnel. In this mode, you create a local TCP port on your computer. RDP Access Through SSH Tunnel (Local TCP Forwarding) Double SSH tunnel connects computers without any dedicated pubic IP addresses behind NAT through an SSH server (if OpenVPN solution is not applicable).

Remote TCP forwarding is a remote port forwarding to a local computer.Local TCP forwarding is a local port forwarding to a remote server.Here are the typical usage scenarios of SSH tunneling: However, you can use the port forwarding technique through the SSH tunnel. It seems impossible since Remote Desktop port 3389 is blocked by the firewall. Your task is to connect to the Windows Server using the RDP client. All other ports are blocked by a hardware firewall or Windows Firewall. For example, you have a Windows Server with only SSH port open (TCP 22).

SSH tunneling is mostly used in the scenarios when you need to connect to a remote computer behind the firewall.
