Operation Methods

• Generate a listener.

• Run the module and fill in the listener configuration.

• Caching the listener means that after the module runs successfully, a virtual listener will be automatically generated according to the filled listener parameters, which is convenient for restoration when the server restarts.
• Module execution results

• After the target machine restarts, any user login will execute userinit.exe and regenerate a Session.
