Paraview can be a little difficult to set up, particularly on Windows machines. First off, you must have passwordless SSH setup. There is no way to type a password when Paraview connects so this step is crucial. Second, you must pass Duo 2-factor credentials. Since there is no prompting the DUO_PASSCODE variable must be set in order to pass a code to Duo when Paraview connects via ssh. This can be handled via the paraview connection settings for Mac and Linux, but not on Windows. Windows systems require a hardcoded value be set prior to launching Paraview. This can be done in Putty by setting the DUO_PASSCODE variable in the session section of the settings.
Go to the Data section of Connection and add the DUO_PASSCODE variable.
Click Add and your screen should look like the following.
Go back to the Session category, select Default Settings, or whichever session is associated with the HPC system, and press Save.
That will then have Duo send a push notification to your device whenever an ssh session is initiated. Note that you will need a smartphone or tablet for this to workSee the Two-factor authentication page for details.
