NAME

       ipwatchd - IP conflict detection tool for Linux

SYNOPSIS

       ipwatchd --config config_file [--debug] [--test]
       ipwatchd --version
       ipwatchd --help

DESCRIPTION

       IPwatchD is a simple daemon that analyses all incoming ARP packets in order to detect IP conflicts.

       Default	configuration  file  uses  "automatic configuration mode" with "passive protection mode" and it should be the best option for most
       systems.

       Configuration mode applies to the daemon instance and it specifies how the list of network interfaces that  should  be  monitored  will	be
       obtained.  In automatic configuration mode IPwatchD detects all network interfaces automatically and sets passive protection mode for them.
       In manual configuration mode it is up to the system administrator to specify list of interfaces and protection modes in configuration file.

       Protection mode specifies the action that will be performed when IP conflict is detected. In active protection mode IPwatchD protects  your
       host  before  IP takeover by answering gratuitous ARP requests received from conflicting system. In passive protection mode it just records
       information about IP conflict through standard syslog interface.

       IPwatchD also supports execution of user defined scripts. See ipwatchd.conf(5) and ipwatchd-script(1) for more details.

OPTIONS

       The following options are supported:

       -c --config
	      Specifies path to configuration file.

       -d --debug
	      Enables debug mode. Debug information are recorded through syslog with "daemon" facility and "debug" priority.

       -t --test
	      Enables testing mode that is useful only for debugging. In this mode every received ARP packet is considered to be conflicting.

       -v --version
	      Prints program version to standard output.

       -h --help
	      Prints short help information to standard output.

CONFIGURATION

       See ipwatchd.conf(5) for more details.
