If you need a different port, vncviewer -user remoteuser localhost::localport Now, to connect, simply type: vncviewer -user remoteuser localhostĪgain, if you have the same username on both machines you can leave out the -user argument. Note that if VNC runs on a different port (5900, perhaps), you'll need to change at least the second port number. If you have the same username on both machines, you don't need this. l tells ssh to use remoteuser as the username. L tells ssh to listen on this machine at port 5901 (the first), and when a program connects there, ssh sends everything it receives to itself on the remote machine, where it then connects it to that machine's port 5901 (the second). Though, from a laptop you probably don't want that.
I suggest you set up a key pair for authentication, then you don't need a password and could even set this up to run at boot. f prompts you for a password if necessary, then goes into the background. N tells ssh not to execute a command (we don't want a shell, just the port forwarding). Set up the tunnel from the client (windows) machine: ssh -N -f -L 5901:remotehost:5901 -l remoteuser remotehost I've just set this up on my machines, so I'll show how to set up the tunnel after you've gotten the server running. It might not be the fastest because of the ssh encryption. So, as I said in a comment, the most secure way is vnc over an ssh tunnel.
