This guide will help you to enable remote shell feature and control operation system with NDU Gateway from your NDU platform instance.

For purpose of this guide, we will use following things:

Instance of NDU platform (How to install you can read here). For this guide we will use smartapp.netcad.com
Installed and configured NDU Gateway (How to install you can read here).

Step 1. Remote shell activation

To activate remote shell in NDU Gateway you should add or change parameter remoteShell to true in the section thingsboard in the general configuration file (tb_gateway.yaml).

Restart the gateway with the new configuration.

Example of the thingsboard section in the general configuration file:

thingsboard:
  host: smartapp.netcad.com
  port: 1883
  remoteShell: true
  remoteConfiguration: false
  security:
    accessToken: PUT_YOUR_GW_ACCESS_TOKEN_HERE

Step 2. Create a dashboard to use the remote shell

To use the remote shell we have to use the widget RPC remote shell from Control widget bundle. To do this we use following steps:

Open Dashboards tab:
We will add a new dashboard:
Open created dashboard, open edit mode by pencil button and add new widget:
Select widget budle “Control widgets”:
Scroll down and select RPC remote shell widget:
We haven’t specify the entity type for the widget so we will Create a new one:
We have to fill required fields and same the entity. Gateway - is our gateway device:
To prevent TimeoutException, we will increase the default RPC command timeout to 5000 milliseconds in the advanced settings tab and press ADD and check mark icon to save the dashboard:
The connected widget looks like (Connection setups automatically):
Now you can use the shell to control device with the gateway. For example we run ls command to get the list of files and directories in the current directory.
