...

In case you have files If any files already exist in that folder already, please proceed to overwrite and replace them with the newly downloaded files.

2. Right Click on Navigate to the .MSI file > Properties > Details and note and right-click on it. Then, select "Properties" and go to the "Details" tab. Note down the version of the client (sensor, ensuring to record only the first 3 three numbers , without the last 0)and omit the trailing zero.

...

3. Navigate to the GYTPOL installation folder directory, typically located at C:\gytpol\data\Analyzer\Config (“C:\” can be replaced with the GYTPOL Installation folder directory), and open you can replace "C:" with the actual installation folder path). Then, open the file named clientUpgrade.json using Notepad++ or Notepad with elevated Notepadprivileges.

4. Please change the following:

   1. “computers”: Under the "computers" section, you can specify the list of computers you are updating. The default setting is “all” and it will update any client that will report to GYTPOL. In case you want to update only a certain list of clients, please write intend to update. By default, it is set to "all," which updates any sensor reporting to GYTPOL. If you wish to update only specific sensors, please list the names of the Endpoints/Servers in within the list , while keeping a json syntax (i.e maintaining JSON syntax, including commas and quotes). For example:

“computers”: [

“pc01”,”pc02”,”srv01”,”dc02”

],

b. “links”: Under the "links" section, you should specify the URL in from which the clients are downloading sensors will download the new version from. Need to provide the GYTPOL server FQDN (applies . This URL should include the Fully Qualified Domain Name (FQDN) of the GYTPOL server. This step is required only the first time the file is edited).

If you are using a utilizing the Remote Employees feature, you can also add include additional links from a web-facing server, such as servers like DMZ, AWS, or Azure servers. The Ensure these links should be added in a json syntaxare added using JSON syntax. For example:

"links": [

      "https://_gytpol:9093/updates/gytpolClient_x64.msi",

"https://some-webserver.domain.com/path-to-msi.msi"

        ],

c. gytpolClient: The Under the "gytpolClient" section, the name of the client sensor file at the end of the “link” in the URL specified on in step 4.b.■  In the initial file should be modified. Initially, it appears as an example . Please change it and should be changed to gytpolClient_x86/.msi for 32-bit systems and gytpolClient_x64.msi files accordingly (marked in yellow).■  You need to change it only for the first upgrade - after that - leave it as it isfor 64-bit systems.

After the initial upgrade, it should remain unchanged.

d. Linux clients update: please use IP address instead of the FQDN in the client link.■  Linux links should be added manually to the json according to the example below, including the version, clientType and fileType (marked in green).[1] For updating Linux / macOS sensors, utilize IP addresses instead of Fully Qualified Domain Names (FQDN) in the sensor link. Additionally, manually add Linux links to the JSON, incorporating version, clientType, and fileType parameters as shown in the example below (marked green):

e. “version”: the client file version you previously checked on step 2. Remember: only the first 3 numbers (for example - Under the "version" section, input the sensor file version obtained from step 2.
