How To Configure Agents

This article covers the following topics:

• Overview
• Point Agent to the Master Server
• User the Master Public Key

Overview

After you install the Node Agent (or if you want to connect existing on-premises Agents to the ER Cloud Master Server), configure the Node Agent to:

1. Point Agent to the Master Server.
2. (Optional) Use the Master Public Key when connecting to the Master Server.
3. (Optional) Specify the Target Group.
4. Test the connection settings.

Point Agent to the Master Server

• On Unix and Unix-like systems, configure the Agent to point to the Master Server with the -i flag. On the Agent host, run as root in the terminal:

  er2-config -i <hostname|ip_address>

• On Windows, open the Enterprise Recon Configuration Tool and fill in the Master server IP address or host name field:
  

For detailed instructions to configure the Agent to point to the Master Server, refer to the respective Agent installation procedure in the Node Agents section.

Use the Master Public Key

What is the Master Public Key

The Master Server generates a Master Public Key which the Node Agent can use to further secure the connection between the Node Agent and the Master Server.

When a Node Agent is configured to use a fixed Master Public Key, it only connects to a Master Server using that Master Public Key. This mitigates the risk of route hijacking attacks.

The Master Public Key can be found on the Server Information page (refer to the View Server Information section) on the Web Console.

To configure the Node Agent to use the Master Public Key when connecting to the Master Server:

• On Unix and Unix-like systems, configure the Agent to only connect to a Master Server that uses a specific Master Public Key with the -k flag. On the Agent host, run as root in the terminal:

  er2-config -k <master-public-key>

• On Windows, open the Enterprise Recon Configuration Tool and fill in the Master server public key field:
  

For detailed instructions to configure the Master Public Key for an Agent, refer to the respective Agent installation procedure in the Node Agents section.
