The latest release of jpcap (v0.00.08) adds support for many new link-layer types other than ethernet.

Minor enhancements have been added to the client.
Settings have been implemented as Java properties and the visualization client now displays packet and byte counts on communication vectors.

The latest version of jpcap, a network packet capture facility for Java, was released today.

v0.00.07 includes the first public release of the simulator. The simulator has an interface identical to jpcap, but instead of capturing live packet data off the wire, it fabricates synthesized packets.

The type of packets generated by the simulator can be controlled using Java properties, allowing application developers to control what types of packets arrive at the capture interface.... read more

The latest version of Jpcap, a network packet capture facility for Java, was released today.

Over the last week, the project has ranked in the the top 20 most active sourceforge projects, peaking at #11 as approximately 500 Java developers and users have downloaded the distributions.

The core packet capture package and library is very solid and has stabilized with no interface changes in the last few weeks. At the same time, development is continuing on the console capture tool and network traffic visualization tools.... read more

jpcap-0.00.05-1.alpha.rpm was released today.

Binary RPMs are currently available for intel and Alpha AXP architecture machines.

This release introduces RPM packages into the build, including an intel binary distribution targeted at users interested in the capture console and visualization tool.

Previous releases were targeted at developers and took a little bit of script editing and hacking to get going on varying development platforms.

This release fixes several outstanding bugs, consolidates exception handling in the native
capture component, and cleans up the RawPacket interface.

Capture statistics and functions to fetch network and netmask information, broken in previous releases, are now fixed.

The capture internals are rewritten to pave the way for a future release of a simulator which has an interface identical to the packet capture system.... read more

jpcap v0.00.03 was released, including a sample application which allows for the real-time graphical visualization of network traffic while capturing packets.

When using the jpcap libpcap bindings, two types of data capture are now supported. Raw packet data capture is available for clients implementing RawPacketListener, and high-level packet object capture is available for clients implementing PacketListener.... read more

v0.00.02 of jpcap was released. This is the first developer's release of the application.

The release contains a shared library which wraps most libpcap functions with hooks enabling packet capture from a Java application.

The release also contains a rudimentary sample Java client application which allows the user to control and view packet capture from from a text-based console.
