Jpcap Description

A network packet capture library for applications written in Java jpcap is a set of Java classes that provide an interface and system for network packet capture and also a protocol library and tool for visualizing network traffic is included. jpcap hides the low-level details of network packet capture by abstracting many network packet types and protocols into Java classes. Internally, jpcap implements bindings to the libpcap system library through JNI (the Java Native Interface). jpcap utilizes libpcap, a widely deployed shared-library for capturing user-level packets. libpcap must be installed on your system in order to use jpcap.jpcap consists of a small shared-library which wraps libpcap plus a collection of Java classes. The shared-library component provides event hooks, communication and data conversion between a running Java VM and libpcap. The 'capture' package contains the core capture system. The 'net' package contains abstractions for many network packet types and protocols. The 'simulator' package contains a network simulator.NOTE: Jpcap is licensed and distributed under the terms of the Mozilla Public License 1.1 (MPL 1.1). Here are some key features of "Jpcap": · A tool for real-time network traffic capture and analysis · An API for developing packet capture applications in Java Requirements: · Libpcap What's New in This Release: New functionality and enhancements: · Rewrote jvm recognition portion of jpcap startup script to look for wider variety of installed virtual machines · Improved FAQ · Added capture time query support to core packet classes · Incorporated significant enhacements submitted by the community. · Added ability to write tcpdump format files. (util.TcpdumpWriter). · Obsoleted SyncPacketCapture class. Functionality now provided by PacketCapture.endCapture(). · Added little endian methods and fillBytes() methods in array helper. · Timeval information now available in both Packet and RawPacket derivatives · Added new accessors to Timeval class. Bugs Fixed: · Fixed a number of minor semantic warnings under new jikes version (1.20)
