NDTS Installation

← Back to Facility Dashboards

Installing and Updating Daemon and Gateway

This page explains how to install, update, uninstall, and roll back the two local NDTS components:

• The Daemon – installed on each spectrometer workstation
• The Gateway – installed on a facility-level server

These components are responsible for harvesting experiment data and transferring it securely to the NAN Repository.

Acquiring Installation Packages

Installation packages are provided as `.tar.gz` archives and are available for download from the Facility Dashboard.

If a package is missing or access is restricted, submit a support ticket to the NAN Repository team.

Gateway Installation

Prerequisites

Before beginning installation:

• Obtain a Gateway UUID from the NAN Repository administrator
• Use a dedicated Linux machine (Ubuntu 20.04 recommended)
• Ensure TCP port 60195 is open to NDTS spectrometer workstations

Installation Steps

# Copy the .gz archive to the gateway system
tar xf filename
cd dtgateway-installer
sudo ./install.sh
# When prompted:
#   Enter the Gateway UUID

Post-Installation

# Check if the gateway is running
sudo systemctl status data-transport-gateway

# If needed, start the service
sudo systemctl start data-transport-gateway

Updating the Gateway

# Run the same installer script from a newer package
cd dtgateway-installer
sudo ./install.sh
# No prompts are shown during update

Uninstalling the Gateway

# Run the uninstall script included in the archive
sudo ./uninstall.sh

Rolling Back the Gateway

# Use the older version’s installer to roll back
tar xf old-version.tar.gz
cd dtgateway-installer
sudo ./install.sh

Daemon Installation (Spectrometer Workstation)

Prerequisites

• IP address of the Gateway
• Exact instrument name (as entered in the Facility Dashboard)
• Workstation UUID (from Facility Dashboard)
• For AlmaLinux, ensure `chkconfig` is installed

Installation Steps

# Copy the .gz archive to the workstation
tar xf filename
cd dtdaemon-installer
sudo ./install.sh
# When prompted:
#   Enter Gateway IP address
#   Enter instrument name (e.g., nmr600)
#   Enter workstation UUID

Updating the Daemon

# Run the same install script
cd dtdaemon-installer
sudo ./install.sh

# Note:
# - Best to update when no acquisition is running
# - The installer will close any running UI automatically

Uninstalling the Daemon

# Run the uninstall script
sudo ./uninstall.sh

Rolling Back the Daemon

# Use the older install package
tar xf old-version.tar.gz
cd dtdaemon-installer
sudo ./install.sh

Next Step: Configure the Daemon
