Configuring X-Win32 for SSH Connections to LC Machines

These instructions assume that your desktop machine is a Windows PC and that the standard LLNL X-Win32 application has been installed with a valid license key.

  1. Start the X-Win32 application: Start > All Programs > X-Win32 > X-Win32

  2. The X-Win32 splash will appear for a few seconds and then go away.

  3. The X-Win32 Configuration dialog box will appear. Click on the Manual... button to setup a new connection:

  4. The Connection Method dialog box will then appear. Select ssh then click the Next button to continue.

    • The New Connection dialog box will appear. Enter the following:
    • Connection Name: A name for this connection - should probably match the intended machine you want to connect to.
    • Host: The real name of the machine
    • Login: Your LC login name on the machine
    • Command: For a CZ machine, this is the type of login window you prefer. Another choice might be /usr/bin/xterm. For an RZ machine, note that you must always connect to the rzgw gateway and then from there, ssh to the machine you want to actually login into.
    • Click the Save button when you are done

    Important: Leave the password boxes blank!
