All: Thanks for the inputs. After reviewing this url http://www.uk.research.att.com/vnc/sshvnc.html and the one given below by David I finally understood what to do from Putty.
Here is what I did: 1. I connected via a normal SSH session to the server, and started the "vncserver" . This time the 'X desktop' was display number '2'. 2. From this format of vnc via secure ssh ssh -L x:localhost:y my_server >From Putty, I created another session . For this one from "SSH->Tunnel" I had the following: - X Display Location : localhost:0 - Added a forward port with : Source : 5903 (i.e x from above) Destination : localhost:5902 (from localhost:y) 3. I saved it. I may have to update the "SSH->Tunnel" regularly as I don't think vncserver will always run (see my query below on that). So I may get a different X display. 4. I started this connect and connected to the server. 5. From my windows I started vncviewer and typed The following: localhost:3 (this in effect is forwarding to port 5902) This happily asked me for the password and started the AfterStep X display manager. I suppose that I can assume that my connection is secure now. Right ? Ok now the vncserver issue. I probably don't need To do 1) is vncserver is always running. The destination port should then always be whatever The display was before. To connect then I just have to do step 4) from my saved forwarded connection and 5). So first off, is it safe to leave "vncserver" always up ? 2nd, How do I make "vncserver" permanently run on the server ? As a test, I just closed the Putty session for the forward connection, and got this message: *************************** Waiting for forwarded connections to terminate... The following connections are open: #0 unknown (remote did not supply name) (t4 r256 i0/0 o0/0 fd 9/9) *************************** I closed the vncviewer session, and this closed The Putty session. Now I restarted Putty for the same forward Connection, and started the vncviewer with localhost:3, and it still works. This tells me that vncserver once started always stays up once I started it. It will probably die when I re-start the server or kill the process. Am I right here ?
