Using Putty through VPN

January 2007

This process will describe using PuTTy to connect to MMM Linux systems and all X-Windows to display back to your remote PC.

Process

-   Establish a VPN Connection
-   Start Exceed
    -   Go to the 'Start' button --> All Programs --> Hummingbird ...
        --> Exceed --> Exceed
            When you execute this, the only thing you will see is a an
            icon down below in the taskbar

-   Open/Setup Putty
    -   Host Name:  name.mmm.ucar.edu
            name should be the name of the unix box you want to access
    -   Protocol:  SSH

    -   In the Left Pane, go to 'Connection --> SSH'
        -   Preferred SSH protocol version:  2

    -   In the Left Pane, to go 'Connection --> SSH --> X11
        -   Check the 'Enable X11 Forwarding' box

    -   Go Back to 'Session'
        -   In the 'Saved Sessions' field, type:  name
                this should be the name of the unix system you want to
                access
        -   Click the 'Save' Button

-   Run a saved Putty session
    -   In the 'Saved Sessions' section, you will see your saved session
    -   Double-click this session and it should run
-   X Forwarding steps after logging in
        After you log into your unix system, you will need to setenv
        DISPLAY to send your x-display to the right place
    -   After logging in, issue the following commands
        -   w
                look in the 'FROM' column of this output.  You will see
                the remote connection
        -   setenv DISPLAY vpn-client191.ucar.edu:0.0
                This is an example of how it might look if you are
                coming via VPN
        -   xclock
                This is just to test that x-forwarding is working
