    NVIDIA Sync helps set up and configure SSH access

    OverviewOverviewConnect with NVIDIA SyncConnect with NVIDIA SyncConnect with Manual SSHConnect with Manual SSHTroubleshootingTroubleshooting

    Step 1
    Install NVIDIA Sync on your laptop

    NVIDIA Sync is a desktop app that connects your laptop to remote devices over a local network. It replaces running manual commands in a terminal with a configured, click through interface. You can use it as a simple interface to manage SSH access and launch development tools on your DGX Spark.

    Your OS has been auto-detected, but you can choose a different option to download.

    x86DownloadARMDownload
    UniversalDownload
    Download

    For Windows: After download, double click the .exe installer and follow instructions.

    For macOS: After download, open nvidia-sync.dmg, drag and drop it into the Applications folder, then launch it from Applications.

    For Debian/Ubuntu: Install from the NVIDIA APT repository.

    • First, configure the package repository:

      curl -fsSL  https://workbench.download.nvidia.com/stable/linux/gpgkey  |  sudo tee -a /etc/apt/trusted.gpg.d/ai-workbench-desktop-key.asc
echo "deb https://workbench.download.nvidia.com/stable/linux/debian default proprietary" | sudo tee -a /etc/apt/sources.list

    • Then, update package lists:

      sudo apt update

    • Finally, install NVIDIA Sync:

      sudo apt install nvidia-sync

    Success: A "Let's Get Started" modal opens and asks you to read and agree to the EULA.

    Step 2
    Complete onboarding by agreeing to the EULA and selecting applications to launch

    Click the link to the EULA, read the EULA, and then select "Agree" in the "Let's Get Started" modal.

    NVIDIA Sync will then prompt you to choose local developer applications for it to launch. You can always add more applications later in the Settings window.

    Select "Next" to proceed.

    Step 3
    Add your DGX Spark to NVIDIA Sync

    NOTE

    Your DGX Spark must be on the same network as your laptop, and you must know its default mDNS hostname or its IP address. Learn more about DGX Spark networking in the documentation.

    Once onboarding completes, NVIDIA Sync shows a modal while it searches for mDNS devices. If your network allows mDNS broadcasting, NVIDIA Sync should detect your Spark (e.g. spark-abcd.local) and prompt you to select it.

    Otherwise, the modal will transition to a form requesting specific fields to connect to your Spark:

    • Name: A descriptive name you will remember (e.g., "My Home Spark")
    • Hostname or IP: The mDNS hostname (e.g. spark-abcd.local) or IP address of your Spark
    • Username: Your DGX Spark user account name
    • Password: Your DGX Spark user account password

    Fill out the fields and select "Add".

    Success: The form will transition to a modal prompting you to get started.

    NOTE

    The password is used to configure SSH key-based authentication only when you add the device. It is not persisted or logged.

    Step 4
    Connect to your DGX Spark and launch the DGX Dashboard

    Select "Get Started" in the modal to connect to your Spark.

    The device window will open near the task or menu bar and then expand and populate with apps that you can launch on your Spark.

    The DGX Dashboard is a pre-installed web application that helps you monitor and manage the system remotely.

    To launch it, select the DGX Dashboard icon in the device window.

    When it opens, you will be prompted to log in using your username and password for the Spark.

    Success: The DGX Dashboard web app opens in your browser and you see main screen.
