NetCap: A Packet Sniffer in Java
A packet sniffer is a wiretap device that plugs into computer networks; unlike telephone circuits, computer networks are shared communication channels. Sharing means that computers can receive information that was intended for other machines (HUB). NetCap is a type of packet sniffer software that captures the network data as well as provides sufficient means for decision making process of administrator. This paper illustrates NetCap and its benefits over existing packet sniffers. NetCap is developed in Java totally as well as it consumes very less memory on the hard disk. It encompasses many functionalities like 3D pie chart statistics, possible malicious IP address detection, TCP flow graph, various coloring rules and filters that may be applied to the captured tabulated network data.
