Install FastX1

You can download the FastX2 FastX1 client from the ITS software download page. After signing in with your HawkID find the FastX link and click on itFastX - ITS Help Desk - Information Technology Services at The University of Iowa page. You will need to sign in with your HawID and password. On the next page that opens up you will see buttons to download a client. Select the one that is appropriate for your system.

Be sure to set the User field to your HawkID. If connecting to Helium then replace 'neon' with 'helium' in the dialog. Then click on the Save button. Once this is established the server connection will appear in the connection list.

Double click on the connection entry to establish an ssh connection. You will be prompted for a password if you are not using a key and Duo will autopush an authentication request to your default device with the Duo app or a phone call to your Duo registerd registered phone number. The screen will now look like the following:

Sessions can be resumed if they are not terminated when the FastX program is closed. Note that FastX sessions are dependent on an ssh connection to the server but are actually distinct. This means that you can disconnect from a server but leave the session running and reconnect to it later. In this scenario, the backend ssh connection to the server has to be established new so this will require Duo authentication. But once the ssh connection is up FastX will find any existing connections on the server. What is important to keep in mind here is that there are is more than one login node per HPC system . Neon has 2 login nodes and Helium has 3. In each case they are round robin resolved that are used in a round robin so that a connection to neon.hpc.uiowa.edu will resolve to either neon-login-1.hpc.uiowa.edu or neon-login-2.hpc.edu. This is important to remember when trying to reconnect to sessions as your new connection will need to land on the same host as the session that you want. If you do this frequently you may want to create explicit connections for each login node.

• Neon
  • neon-login-1.hpc.uiowa.edu
  • neon-login-2.hpc.uiowa.edu
  Helium
  • helium-1.hpc.uiowa.edu
  • helium-2.hpc.uiowa.edu
  • helium-3.hpc.uiowa.edu

We kindly ask that you please terminate any sessions that you no longer need as they do use resources.
