Connecting to Galileo from Linux

  • Running Programs:

    • OpenNX
      If you need to run programs that have graphical interfaces (things you click on, rather than just text you type), the best choice for communicating with Galileo is OpenNX. It is by far the fastest way to run graphical applications on Galileo. For information about how to use it, see the following link:

      Using OpenNX to talk to Galileo >>

      OpenNX will work fine for non-graphical programs, too.

    • Other alternatives
      Alternatively you can use SSH instead of OpenNX to connect to Galileo. Just open a terminal windor and type:
      ssh username@galileo.phys.virginia.edu
      or, equivalently:
      ssh galileo.phys.virginia.edu -l username
      If you need to run graphical programs, you'll have to make sure that SSH is configured to forward X connections from Galileo to your computer. If SSH isn't already configured this way on your computer by default, you can turn on X forwarding each time you use ssh by adding the "-X" option to the command, like this:
      ssh -X username@galileo.phys.virginia.edu
      Note that graphical applications will be orders of magnitude more sluggish when run this way than they would be when run through OpenNX.

  • Copying Files to and from Galileo:

    • From the command line:

      From the Linux command line, you can copy files to and from Galileo using sftp, scp or rsync. If you're only copying a few files, you may find sftp the most convenient of the three choices. To use it, just type:

      sftp username@galileo.phys.virginia.edu

      and log in. You'll then be able to use command like "dir", "cd", "get" and "put" to list your files on Galileo, change to another directory there, get a file, or put a file, respectively. You can also type "help" for more information.

      If you need to copy a whole directory (or tree of directories), you should look at the rsync command. For example, to copy everything from a directory called "data" on your local computer into a directory of the same name under your home directory on Galileo, you could type this (on your local computer):

      rsync -rv ~/data/ username@galileo.phys.virginia.edu:data/

      (Note the trailing slashes. They're important.)
      For complete information about using rsync, type "man rsync" on your local computer.

    • Using graphical tools:

      • Gnome

        If you're using the Gnome desktop environment, you can do the following to create an icon on your desktop that will, when clicked, open a file browser showing your home directory on Galileo:

        1. Right-click on the desktop, and select "Create Launcher" from the menu.
        2. For "Type", choose "Location" from the drop-down menu.
        3. In the "Name" box enter something like "My home directory on Galileo".
        4. In the "Location" box enter:

          sftp://username@galileo.phys.virginia.edu/home/username

          where "username" is your user ID (something like "mst3k", for example).

        5. You can leave the "Comment" box blank, then click "OK".
        6. You should now have a new icon on your desktop. When you click it, you should be prompted for your password, and then shown your Galileo home directory in a file browser.
      • KDE

        If you're using the KDE desktop environment, you can do the following to create an icon on your desktop that will, when clicked, open a file browser showing your home directory on Galileo:

        1. Right-click on the desktop, and select "Create New..." --> "Link to Location (URL)" from the menu.
        2. In the "File name" box enter something like "My home directory on Galileo".
        3. In the "Enter link to location" box enter:

          sftp://username@galileo.phys.virginia.edu

          where "username" is your user ID (something like "mst3k", for example).

        4. You should now have a new icon on your desktop. When you click it, you should be prompted for your password, and then shown your Galileo home directory in a file browser.
