Common Configuration Tasks

A list of common configuration tasks to ensure that your computer can connect to the NGS computing resources made available by the University of Pittsburgh Center for Simulation and Modeling

  1. If you do not already have one, please download an SSH client for your machine. On Macs, the SSH command is available via the Terminal application (look in the Utilities folder inside of Applications). On Windows machines, you will need to download a separate program. A commonly used (free) SSH client for windows is PuTTY.

  2. Download a secure FTP client for your laptop (if you do not already have one). A simple (graphical) secure FTP client for both Mac and Windows OS is Cyberduck. On Windows systems, you can also use the PuTTY SFTP program.

  3. Test your connection to the Pitt SSLVPN service:

    • Open a browser window to

    • Make sure the "Connection Method" is set to Network Connect

    • Enter your Pitt username and ID, and press "Log In"

    • After the "Loading Components" page, you should be presented with a page that lists a set of roles. One of them should be Firewall-SAM-USERS-NetworkConnect - choose that role

    • On the next page, push the "Start" button next to the Network Connect application

  4. If you have not already done so, request a user account/allocation on the Center for Simulation and Modeling (SAM) cluster (known as Frank) by filling out the required information on this page

  5. Test out your login on the SAM cluster (you should use your Pitt id and password to log into the linux system at, and you will need to be logged into the Pitt SSLVPN with the Network Connect client running, as described above in step 3):

    On a Mac:

    • Open the Terminal application

    • In the window, type the following:


      where you replace the pitt_username portion with your Pitt id

    • When prompted, you should enter your Pitt password (the password that goes with your Pitt id)

    On Windows:

    • Open the SSH client you downloaded and installed

    • Choose \'Open a new connection\' (or the equivalent command for your software)

    • Use the following information:

      Port: 22

      Host id:

      User id: (your Pitt id)
