NAME

SYNOPSIS

DESCRIPTION

14       IPwatchD  is  a simple daemon that analyses all incoming ARP packets in
15       order to detect IP conflicts.
16
17       Default configuration file uses  "automatic  configuration  mode"  with
18       "passive  protection  mode"  and  it should be the best option for most
19       systems.
20
21       Configuration mode applies to the daemon instance and it specifies  how
22       the  list  of  network  interfaces  that  should  be  monitored will be
23       obtained. In automatic configuration mode IPwatchD detects all  network
24       interfaces  automatically and sets passive protection mode for them. In
25       manual configuration mode it is up to the system administrator to spec‐
26       ify list of interfaces and protection modes in configuration file.
27
28       Protection  mode  specifies  the  action that will be performed when IP
29       conflict is detected. In active protection mode IPwatchD protects  your
30       host  before  IP takeover by answering gratuitous ARP requests received
31       from conflicting system. In passive protection  mode  it  just  records
32       information about IP conflict through standard syslog interface.
33
34       IPwatchD   also   supports  execution  of  user  defined  scripts.  See
35       ipwatchd.conf(5) and ipwatchd-script(1) for more details.

OPTIONS

38       The following options are supported:
39
40       -c --config
41              Specifies path to configuration file.
42
43       -d --debug
44              Enables debug mode. Debug information are recorded through  sys‐
45              log with "daemon" facility and "debug" priority.
46
47       -t --test
48              Enables  testing mode that is useful only for debugging. In this
49              mode every received ARP packet is considered to be conflicting.
50
51       -v --version
52              Prints program version to standard output.
53
54       -h --help
