Changing the default ports in the Engine

Changing the default ports in the Engine


The Engine listens to a set of default TCP and UDP port numbers for communicating with the rest of the Nexthink components and serve external requests.

Some of the ports used by the Engine are configurable.

Changing the ports from the Web Console

If you need to change them for any particular reason:

  1. Log in to the Web Console of the Appliance that hosts the Engine.
  2. Select the APPLIANCE tab at the top of the Web Console.
  3. Click Security on the left-hand side menu.
  4. Under Nexthink Ports, find the following configurable ports:
    1. In Collector TCP port, type in the port number for the TCP connection of the Collector with the Engine that enables the Engage and Act features, as well as the automatic updates. For this connection, you must use a port that does not require root privileges; that is, the port number must be above 1024. Default is 8443.
    2. In Collector UDP port, type in the port number for the UDP connection that sends device information and user activity to the Engine. Default is 999.
    3. In Web API, type in the port number of the TCP connection used to integrate with the Engine via the NXQL language. This connection also requires a port number higher than 1024. Default is 1671 (changed to 1679 in the example below).
  5. Click SAVE to make your changes permanent. The Engine restarts if you changed either the UDP port or the Web API port.

After saving your changes, remember to configure the Collectors with the new selected port numbers during their deployment or to update already deployed Collectors with the Collector Configuration Tool.

In the same way, adapt your integrations to use the new Web API port of the Engine and, to test your NXQL queries, include the new port number in the URL of the NXQL Editor.
