IPwatchD is simple daemon that uses libpcap to detect IP conflict on Linux. It can be configured to listen on one or more interfaces (alias interfaces are also supported) in active or passive mode. In active mode IPwatchD protects your host before IP takeover by answering Gratuitous ARP requests received from conflicting system. In passive mode it just records information about conflict through standard syslog interface.
Since version 1.1 IPwatchD also supports desktop notification.
IPwatchD is released under the terms of the GNU General Public License.
