man farpd (Administration système) - farpd
NAME
farpd - ARP reply daemon
SYNOPSIS
farpd [-d] [-i interface] [net ...]
DESCRIPTION
replies to any ARP request for an IP address matching the specified destination net with the hardware MAC address of the specified interface , but only after determining if another host already claims it.
Any IP address claimed by is eventually forgotten after a period of inactivity or after a hard timeout, and is relinquished if the real owner shows up.
This enables a single host to claim all unassigned addresses on a LAN for network monitoring or simulation.
exits on an interrupt or termination signal.
Note: The program name has been changed in Debian GNU/Linux from the original name (arpd) to avoid name clash with other ARP daemons.
The options are as follows:
- -d
- Do not daemonize, and enable verbose debugging messages.
- -i interface
- Listen on interface . If unspecified, searches the system interface list for the lowest numbered, configured ``up'' interface (excluding loopback).
- net
- The IP address or network (specified in CIDR notation) or IP address ranges to claim (e.g. ``10.0.0.3'', ``10.0.0.0/16'' or ``10.0.0.5-10.0.0.15''). If unspecified, will attempt to claim any IP address it sees an ARP request for. Mutiple addresses may be specified.
