Check file integrity

Before installing the Secure SD-WAN Engine software from downloaded files, check that the installation files have not become corrupt or been changed.

Using corrupt files might cause problems at any stage of the installation and use of the system. Check file integrity by generating a file checksum of the files. Compare the checksum of the downloaded files with the checksum for the software version in the Release Notes or on the download page at the Forcepoint website.

Note: In Windows environments, you can use Windows PowerShell to generate checksums. Several third-party programs are also available.

Steps

  1. Look up the correct checksum at https://⁠support.forcepoint.com.
  2. Change to the directory that contains the files to be checked.
  3. Generate a checksum of the file using one of the following commands, where filename is the name of the installation file:
    • sha1sum filename
    • sha256sum filename
    • sha512sum filename
  4. Compare the displayed output to the checksum for the software version. They must match.
    CAUTION:
    Do not use files that have invalid checksums. If downloading the files again does not help, contact Forcepoint Customer Hub to resolve the issue.

Next steps

If you downloaded the installation files as a .zip file, unzip the contents at the installation location.
