Lightweight libpcap Java (JNI) wrapper.
- pcap-java uses JNI to interact with the native stuff, while other libraries use JNA.
Sample code:
Pcap.init();
PcapHandle handle = Pcap.openLive("any", 120, 1, 10);
PcapDumper dumper = handle.dumpOpen("dump.pcap");
BpfProgram filter = handle.compile("tcp and dst port 80");
handle.setFilter(filter);
filter.free();
LinkType datalink = handle.datalink();
handle.loop(-1, (packetHeader, rawPacket) -> {
try {
Packet packet = new Packet();
packet.decode(rawPacket, datalink);
System.out.println(packet);
dumper.dump(packetHeader, rawPacket);
dumper.flush();
} catch (LayerDecodeException | PcapException e) {
e.printStackTrace();
}
});
dumper.close();
handle.close();
