To start this setup, you need an additional piece of information. First, you must have your SSH package installed. In Linux, they are the OpenSSH packages. Check your distribution to decide what package you need to install (some installed it as standard packages). Secondly, you need a Windows SSH Client (other OS version, like MAC, are also available). I recommend PuTTY. It is a wonderful free SSH client and you can download them from this link. Download the document as well and read them carefully. The other good free SSH client are: Tera Term Pro + TTSSH: An SSH Extension to Tera Term, SSH Secure Shell Client by SSH.com (only free for non-commercial use). I will break down again into steps, so it is easy for you to follow.
Open up the command putty.exe by double-click it. It will brings up the interface. First, setup the connection info in Host Name (or use IP) field and select SSH (SSH is using port 22). In Connection Category, find the Connection tree. In SSH, expand it and you will see Tunnels window. Click "Enable X11 forwarding". It is setting the default to X display at "localhost:0". Now, go back to Session and save this session with a name you like. I normally use the Host Name to make me easily remember where I am connecting to.
In the example of Hummingbird Exceed, this is what you need to do. (For other X client, the setup is similar). Open up the Xconfig from your Exceed folder. In your "Screen Definition", change to "Multiple" Window mode and save it. Next, open up your "Communication" icon and set the Startup mode to "Passive".
Now you are done. To test it, first using PuTTY (or other SSH client) to connect to your server. The first time connection, it will ask you whether you want to cache the Security Key or not. (Yes is normal choice). Once log in is done, fire up your Exceed. It will stay in the background. Now you can execute any of your X application and it should forward the X application via SSH to your local screen. For example:
$ xclock & |
We should now see the Xclock is running on your local screen.
Now you see the difference is that you do not see all your X Window. You are simply running X application one by one and forwarding via SSH to your local screen. Therefore, you need to know the command for running each X application. All the control are done via SSH client window. To me, the security is worth the slightly inconvenience!
For user running the X-Win32, you can use this link for your SSH + X11 forwarding setup.
