You'll need an SSH client to connect to the Arrow.

IMPORTANT. In order for the your home directory to be properly setup on Arrow, please connect to the cluster using Putty on Windows or ssh from a UNIX/Linux workstation using the command: [email protected] for the initial login. After that nomachine may be used to establish graphical desktop environment.

How to Connect: Details

SSH

• Access to the TRACC cluster requires use of an SSH client. Free SSH clients are available for Windows, and are included or available for MacOS, and most varieties of Linux/UNIX.

• Alternatively, the NoMachine NX client also uses SSH. For ARROW you will have to select the GNOME DESKTOP.

• If you're using a graphical application on the cluster, you'll need to enable X11 forwarding in your client. For Windows clients, this will usually involve checking a checkbox; for MacOS and Linux, you can do this:

ssh -X [email protected]
