This is a little convoluted only because most of the free versions of VNC don’t include encryption directly so in some cases you need to combine two programs to make it work. The Viewer: Connecting to the VNC Server using SSH encryption: If you forget what Display number your server is running on you can use the “vnccheck” command on katahdin.Ģ. Your display number will likely be different. You will use this information later when you want to connect to it. Log file is /home/guest/.vnc/katahdin:19.logĪt this point you have a VNC server running on display :19. Starting applications specified in /home/guest/.vnc/xstartup New ‘Katahdin:19 (guest)’ desktop is Katahdin:19Ĭreating default startup script /home/guest/.vnc/xstartup Xauth: creating new authority file /home/guest/.Xauthority You will require a password to access your desktops. The output of this command will look something like this: If this is the first time that you have run this command it will ask you to set up a password. To do this, first ssh in to your account and run the command: The first thing to do is to set up the VNC server on katahdin. The Server: Setting up the VNC server on Katahdin The Viewer program is run on a remote machine to connect to the server and display the servers desktop.

The Server program is run on the machine that you want to have access to. VNC has two parts, the VNC Server and the VNC Viewer (client). How this is set up depends on what SSH client you use and what vncviewer program you use. Since Katahdin has only the SSH port open to the outside, the VNC ports need to be tunneled through SSH to a port on your machine. It is possible to connect to the system securely using VNC with the help of SSH. VNC is a good way to be able to use that capability. It allows you to access your data via a graphical environment and run programs such as Matlab, ncview, etc. Katahdin is the login node for the Katahdin cluster.
