       ipwatchd - IP conflict detection tool for Linux


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


       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

       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.


       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.


       See ipwatchd.conf(5) for more details.
