Overview

There are two versions of the Windows Node Agent:

Install the Windows Node Agent with database runtime components if you intend to run scans on Microsoft SQL Server, IBM DB2, or Oracle databases.

Install the Node Agent

1. Log in to the ER2 Web Console.
2. Go to Settings > Agents > Node Agent Downloads.
3. On the Node Agent Downloads page, download the appropriate Windows Node Agent installer.
4. (Optional) Verify the checksum of the downloaded Node Agent package file.
5. If there is a previous version of the Node Agent installed, remove it first.
6. Run the downloaded installer and click Next >.
7. To install the Node Agent, select Install.
   

8. While the Node Agent is being installed, the installer prompts you to configure your Node Agent to connect to the Master Server.
   

   Get the Master Server public key from the Server Information page.
9. Fill in the fields and click Test Connection.
10. Click Finish to complete the installation.

Verify Checksum for Node Agent Package File

You can determine the integrity of the downloaded Node Agent package file by verifying the checksum before installing the Node Agent.

1. Download the Node Agent package file.
2. Run the commands in a terminal to generate the hash value for the Node Agent package file.

   • MD5 hash (128-bit)

     # Syntax: certutil -hashfile <path to Node Agent package file> MD5 certutil -hashfile er2_2.x.x-windows-x64.msi MD5
     Example MD5 hash: f65a2cd26570ddb7efb6a2a4318388ac

   • SHA1 hash (160-bit)

     # Syntax: certutil -hashfile <path to Node Agent package file> SHA1 certutil -hashfile er2_2.x.x-windows-x64.msi SHA1
     Example SHA1 hash: 33bcd6678580ae38a03183e94b4038e72b8f18f4

   • SHA256 hash (256-bit)

     # Syntax: certutil -hashfile <path to Node Agent package file> SHA256 certutil -hashfile er2_2.x.x-windows-x64.msi SHA256
     Example SHA256 hash: 1ee094a222f7d9bae9015ab2c4ea37df71000556b3acd2632ee27013844c49da

3. In the ER2 Web Console, go to the Settings > Agents > Node Agent Downloads page. The Hash column lists the expected hash values for each Node Agent package file.

4. Compare the generated hash values from Step 2 with the expected hash values listed in the Web Console; both hash values should be equal.

   If the hash values do not match, check that your network connection is stable, download the Node Agent package again from the Web Console, and verify the checksums again. If the issue still persists, contact Ground Labs Technical Support.

Configure the Node Agent

To configure the Node Agent (to point to a new Master Server, or update the Master Public Key):
