[KB7011] Configure the ESET Mirror Tool to download updates from another ESET Mirror Tool

Issue

• Configure the ESET Mirror Tool to download updates from another ESET Mirror Tool in a network setup, as shown in the scheme below:

  

Solution

1. Set up the first ESET Mirror Tool on the computer connected to the internet
2. Set up a second ESET Mirror Tool to download update files from the first ESET Mirror Tool
3. Configure ESET applications to download updates from the second ESET Mirror Tool

I. Set up the first ESET Mirror Tool on the computer connected to the internet

Create an offline repository using ESET Mirror Tool and configure your local web server to distribute the offline repository (follow the instructions in sections I, II and III of the linked Knowledgebase article).

II. Set up a second ESET Mirror Tool to download update files from the first ESET Mirror Tool

1. Create folders for ESET Mirror Tool operation:

   • A folder for the offline activation file activation_file.lf (for example, C:\mirror)
   • A folder for intermediary files (for example, C:\mirror\temp)
   • A folder for the downloaded files (for example, C:\mirror\out)
     
     

2. Copy the ESET Mirror Tool to the desired folder.

3. Copy the offline activation file (activation_file.lf) to the desired folder (for example, C:\mirror).

4. Open the Command Prompt, navigate to the Mirror Tool folder and run the following command:

   MirrorTool.exe --mirrorType regular --updateServer http://1.2.3.4/eset_upd/ep13 --intermediateUpdateDirectory c:\mirror\temp --offlineLicenseFilename c:\mirror\activation_file.lf --outputDirectory C:\mirror\out

   Provide the IP address of the HTTP Server

   In --updateServer provide the IP address of the HTTP Server configured in Section I (in this example 1.2.3.4). This example shows how to download program module updates for ESET Endpoint applications version 13 (ep13). You can change the command to download update files for different ESET applications.

5. Configure your local web server to distribute the offline repository (follow instructions in section III of the linked Knowledgebase article).

   Configure ESET application to function as a mirror server

   If you have installed an ESET application on the device where you are setting up the second ESET Mirror Tool, you can configure an ESET endpoint application to function as a mirror server instead of installing and configuring a local web server.

III. Configure ESET applications to download updates from the second ESET Mirror Tool

Perform the following steps on each computer in Subnet 3 to download ESET application updates from the mirror server.

If you are managing computers using ESET PROTECT or ESET PROTECT On-Prem, you can adjust the settings below using a policy in ESET PROTECT or ESET PROTECT On-Prem.

1. Open the main program window of your Windows ESET application.

2. Press the F5 key to access Advanced setup.

3. Click Update and expand Profiles → Updates. Disable the toggle next to Choose automatically and type the IP address of the mirror server created in Section II to the Custom server field (In this example, http://10.20.30.40:8080/esetupdate/). Click OK.
