NOTE: The -X flag has changed in OpenSSH 3.8 and later, X11 forwarding is performed in a way that applications run as untrusted clients by default. Please refer to the SSH documentation for more.

% ssh -X can also change this option in the SSH configuration files. If it is not, you can enable it by calling SSH with the “-X” option. X11 forwarding is typically turned on by default in most *NIX distributions of SSH. Make sure the checkbox “Forward X11” is checked.Enter the hostname and any other desired information.

Either create a “New” entry, or select an existing one and click “Edit“.

Go to the menu item Favorites -> Edit Favorites.

MacSSH, and OpenSSH support both SSH2 and port forwarding.

NOTE: We recommend against using any SSH program that does not support SSH version 2. We outline a few examples below for common clients: To set up SSH port forwarding, you simply need to enable that option in your client. With SSH compression turned on, it can actually be faster to use SSH than not on low bandwidth connections.There is no need to modify permissions for foreign hosts, and no need to set your DISPLAY variable. In most situations, all you need to do is have your X server running. Most importantly, the transmission is secure.There are several reasons this is a preferred method to run X11 applications remotely: The result is that with very little configuration, this traffic is forwarded to your machine, encrypted in an SSH “tunnel”. This allows network traffic to be forwarded from the remote machine to your local box through SSH. Many, but not all SSH clients currently available support X11 Forwarding, and general port forwarding.
