SETTING UP AN SSH TUNNEL FOR REMOTE OBSERVING

   On Mac, Windows and some Linux, the -via option is not available. On 
   a Mac, run
     ssh -f -L 590N:fusion00:590N YOURLOGIN@remote.naic.edu sleep 14400
   in a terminal window. Then open Vncviewer (just use the icon) and select
     display > open -- localhost:N
   in both lines, N is the important number from above.
   For Linux, use the same first line; then run 
     vncviewer localhost:N
   For Windows, download Putty, set 
     Session > Host name              = remote.naic.edu
     Session > Protocol               = ssh
     Connection > Auto-login username = YOURLOGIN
     Connection > Tunnels  
       Source port  = 590N
       Destination  = fusion00:590N
   And connect. In VNCViewer, open 
      localhost:N
