Introduction
NCProxy mode can be useful to facilitate device and agent connections to a Site Controller at locations with limited or restricted internet connectivity. In this document you will find details of how to setup a computer in Proxy mode, and how to configure Naverisk Agents to reference the Proxy Computer.
PLEASE NOTE:
An NCProxy is only required when agents can’t connect to the internet.
Using a Network Controller on a site will push all Naverisk traffic through it.
We will use an example scenario to setup one computer at a remote site to act as a Network Controller (This computer MUST have connectivity back to a Site Controller).
The second stage will be to install and configure an Agent with no internet connectivity at the remote site
What is a Network Controller ?
A Network Controller is an entity in Naverisk which is used as an intermediary for Agent – Site Controller communications. The idea is that Agent connections can be processed and streamlined by the Network Controller before being passed on.
What is a Site Controller ?
The Site Controller is the core of the Naverisk system, the program which processes information, interacts with Agents, the Network Controller, the database and the website to provide the functions of your Naverisk system.
1.0 Setup a computer to act in NCProxy mode
1.1 Install Agent
Install the standard agent on the device that is going to be the Network Controller and make sure it can connect to the Site Controller.
1.2 Configure the device as a Network Controller
Connect to the Naverisk Site from the device. From the Device Management screen, select your device and choose the option 'Upgrade to Network Controller' from Device Tasks.
1.3 Configure the device as NCProxy Computer
Once the device has been upgraded to a Network Controller, there should be a configuration file called 'NC.cfg'at %programdata%\Naverisk\Network Controller\.
Add a site specific line at the end of this file as follows:
NCProxy=<IP ADDRESS OR FQDN OF SITE CONTROLLER>, 9202
This is telling the new Network Controller how to connect to the site Site Controller, and use the default listening port of 9202
1.4 Restart Device
Restart this device for the change to take effect
2.0 Install and Configure an Agent
2.1 Install Agent
From the Network Controller, install the Agent to further devices, ensuring that you select the new NC at the correct client level as below:
2.2 Configure Agent
Once the Agent has been installed to the new device, navigate to the 'NAS.cfg' file found at %programdata%\Naverisk\Agent\. Add your site specific entry as below:
NCProxy=<IP ADDRESS OF NETWORK CONTROLLER>
This is telling the Agent to use the designated device as a proxy
2.3 Restart Agent
Restart the agent service on the device for the change to take effect
