Local TCP checks and report import

Run the downloaded script on your computer, then import its JSON report. This page does not scan automatically or upload your file. Results stay in this page session only.

  1. Download the script

    Requires Windows PowerShell 5.1 or PowerShell 7.

    Download script
  2. Run it locally

    Open a terminal in the download directory and run this command. You can change the output file path. Existing files are preserved with a numbered suffix.

    Use PowerShell. If system policy blocks the script, follow your administrator’s approved procedure or use the Python script; do not disable security protections.

The scripts connect only to 127.0.0.1 and ::1, with up to four concurrent attempts and a 1.5-second timeout each. They send no application data, read no process information and require no administrator privileges.

If IPv6 is unavailable, its attempts are reported as failed with a reason. A successful connection does not reveal the listening process, protocol or public reachability.
