1. Connect to a linux remote. For SSH, open your Machine user settings and change the remote.autoForwardPortsSource to process then reload.
2. Start a process that runs as root and listens on a port and has the port number in the command line. Some examples if you need inspiration:

• sudo npx http-server -p 5000
• Open the VS Code repo in a Codespace. Port 6080 fits these requirements.

3. Verify that:

• if you have the ports already forwarded that they get their "Running Process" cell filled in correctly in the Ports view.
• if the port wasn't already forwarded that you get the auto-forward notification.
  Pay particular attention to the "Running Process" column of the Ports view. The pid and command line should be correct, but it is possible they could be incorrect (in that case please file a bug!).
