Can开发者_StackOverflow社区 someone please guide me on listening to ARP broadcasts in Java?
You can use JpCap to listen to ARP Packets.
Jpcap is a Java library for capturing and sending network packets.
Using Jpcap, you can develop applications to capture packets from a network interface and visualize/analyze them in Java. You can also develop Java applications to send arbitrary packets through a network interface.
Jpcap has been tested on Microsoft Windows (98/2000/XP/Vista), Linux (Fedora, Mandriva, Ubuntu), Mac OS X (Darwin), FreeBSD, and Solaris.
Jpcap can capture Ethernet, IPv4, IPv6, ARP/RARP, TCP, UDP, and ICMPv4 packets.
Jpcap is open source, and is licensed under GNU LGPL.
Edit: The last commit on JPCAP in github is from 9 years ago.
