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.
