On-Premise Poller checksum validation

You can verify the authenticity of the downloaded Site24x7 On-Premise Poller with SHA256 checksum validation. This ensures that the downloaded agent is credible and is not tampered with by any malicious code or software.

To verify the authenticity of the agent

  1. Download the checksum file based on your architecture.

    Operating system Architecture Link
    Windows 32-bit Download
    Windows 64-bit Download
    Linux 32-bit Download
    Linux 64-bit Download
  2. Compare the checksum value provided in the downloaded file with the downloaded On-Premise Poller. Follow the steps below to validate the checksum value.
    • For Linux systems, execute the following command:
      sha256sum Site24x7OnPremisePoller.bin
    • For Windows, you can use either of the following commands.
      • Open the Command Prompt and execute the following command:
        certutil -hashfile Site24x7OnPremisePoller_64bit.exe SHA256
      • Open Windows PowerShell and execute the following command:
        Get-FileHash Site24x7OnPremisePoller_64bit.exe -Algorithm SHA256
  3. After executing the commands, you will obtain a checksum value; check that value with the one downloaded from the checksum file.
    Sample output:


    If the checksum values differ, do not use the file.

Verify the signature of your agent binaries

  1. Go to the folder in which the On-Premise Poller is installed on your Windows machine.
  2. Right-click the file (Site24x7OnPremisePoller.exe or Site24x7OnPremisePoller_64bit.exe based on your OS) and select Properties.
  3. Navigate to the Digital Signatures tab in the Properties window.
  4. The file is signed by ZOHO Corporation Private Limited. The signature will be shown here as seen in the image below:


    If the signature differs, do not proceed with installation and contact
