IPMonitor Component

Properties Methods Events Configuration Settings Errors

The IPMonitor component is used to listen to network traffic.

Syntax

nsoftware.IPWorks.Ipmonitor

Remarks

The IPMonitor component will bind to a specific local host address and listen for network traffic received by the interface. The interface must support promiscuous mode (may not work in many wireless cards because of security considerations), and must be installed on Windows 2000 or greater.

NOTE: If your computer connects to a switch, the switch will only forward packets addressed to your computer. If your computer is on a hub, then you will receive everything.

The use of this component requires administrative permissions.

The first step in using the IPMonitor component is to set LocalHost to the IP address whose traffic you wish to monitor, then set Active to True. For each packet that crosses the interface, the component will parse the header and fire an IPPacket event.
