ipwatchd - IP conflict detection tool for Linux
ipwatchd --config config_file [--debug] [--test]
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:
Specifies path to configuration file.
Enables debug mode. Debug information are recorded through
syslog with "daemon" facility and "debug" priority.
Enables testing mode that is useful only for debugging. In this
mode every received ARP packet is considered to be conflicting.
Prints program version to standard output.
Prints short help information to standard output.
See ipwatchd.conf(5) for more details.
