CIRC users may access the CIRC systems in two different ways: using command-line and/or using a graphical user interface (GUI). A GUI connection is used when you wish to visually interact with your jobs and can be done through the BlueHive login node. New users may find a GUI interface easier than a command-line connection. To login to the CIRC machines, follow the steps below based on your operating system and according to the type of login you wish to use.

Connect using the Command Line

  1. Connect to the VPN (if necessary)

  2. Open Terminal.app (/Applications/Utilities/Terminal.app)

  3. At the prompt, type:

    ssh YourNetIDHere@bluehive.circ.rochester.edu

    and press enter or return.

  4. Enter your NetID password when prompted and press enter. A message will appear that indicates you have logged in successfully. You are now logged in to BlueHive.

    Note: You will not see anything appear as you type your password!

Connect using a Graphical User Interface

A GUI connection is used when you wish to visually interact with your jobs and can be done through the BlueHive login node. The tutorials below list instructions on how to install and use several GUI programs suggested for use on the CIRC machines. Instructions for using the X2Go GUI are presented.

The X2Go Client is free to download and works on any system. The CIRC recommends this method as it provides the fastest access to CIRC systems.

  1. Download a copy of X2Go and XQuartz if not already installed:

  2. For X2go, open the disk image (.dmg) file, and drag the application to your Applications folder.

  3. Note that installing XQuartz may require a system reboot

  4. Launch X2Go from your Applications folder. You will be presented with a blank connection setup window. Enter a name for this connection, bluehive.circ.rochester.edu as the host name, your unique NetID assigned by the University as login, and GNOME as the session.

  5. Adjust preferences in the Connection and Settings window to your liking. You can increase quality by changing speed to LAN in the Connection tab, and edit the default window size in Settings.

  6. In the Settings tab, uncheck Client-side printing support.

  7. In the Shared Folders tab, uncheck `Use SSH port forwarding to tunnel file system connections through firewalls` and make sure there are no shared folders listed.

  8. Click OK once you are done configuring options.

  9. You can then double-click on the session you have created to connect to BlueHive.

To exit X2Go, simply close the window.
