$Id: README,v 1.19 2004/03/16 23:38:31 pcharles Exp $ jpcap README General Information jpcap is a set of Java classes which provide an interface and system for network packet capture. 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. jpcap is licensed under the Mozilla Public License. See docs/MPL-1.1.txt. Passive Packet Capture vs. Active Packet Injection jpcap is passive capture mechanism. If you are interested in creating and injecting arbitrary packets into a network, check out the sister project 'jpwrite' at http://www.sf.net/projects/jpwrite. Together, jpcap and jpwrite are a powerful combination. Running the Samples If you have installed from RPM and are looking to run the capture tool, try /usr/bin/jpcap. If you installed from .gz, try ./jpcap. jpcap can also be run in 'simulator' mode. In this mode, a pseudo network interface randomly generates network traffic for capture. The simulator can be enabled in properties/tool.properties. Unix vs. Mac OS X vs. Windows Active jpcap development is taking place on Unix platforms. However, jpcap should run on any platform where libpcap is implemented. For building the jpcap library on Windows, the MinGW environment is recommended. Also, the Windows port of libpcap, known as winpcap, is required. For more information, have a look at docs/BUILD.windows. jpcap on Mac OS X is supported. Refer to the file docs/BUILD.osx. Application Developers (using the packet capture library in other apps) If you are a Java developer interested in using jpcap to capture packets in an application you are developing, you need to do the following: o In your Java CLASSPATH, include jars/net.sourceforge.jpcap-x.yy.zz.jar plus all jars found in thirdParty/jars. o Native bindings to libpcap are provided precompiled for intel Linux. The Java wrapper shared object is src/java/net/sourceforge/jpcap/capture/libjpcap.so This file needs to be included in your LD_LIBRARY_PATH. If you are working on another platform, you'll need to build the jpcap library and shared object yourself, see below. o All capture operations are performed using methods from the class net.sourceforge.jpcap.capture.PacketCapture o Javadocs are located in jars/javadoc_net.sourceforge.jpcap-x.yy.zz.jar o Examples are provided in the package net.sourceforge.jpcap.tutorial. More specific documentation on the jpcap java packages can be found in src/java/net/sourceforge/jpcap/README. If you checked out jpcap from the CVS repository and are looking for information on building the jpcap library in this tree, see docs/BUILD.[platform]. Additional information can be found on sourceforge.net, where development is hosted. jpcap -- http://www.sf.net/projects/jpcap Contributing If you are using jpcap and have made enhancements or bug fixes to the core capture library, please contribute them back to the master source pool. You can contribute by posting a message to the discussion forums at http://www.sf.net/projects/jpcap, or by emailing the project administrator directly via pcharles at users.sourceforge.net. If you've developed an application using jpcap, we're interested in hearing about it. Happy Hacking!
