# NAME

rarpd — Reverse ARP Daemon

# SYNOPSIS

rarpd | [-adfl] [interface [...]]

# DESCRIPTION

rarpd services Reverse ARP requests on the Ethernet connected to interface. Upon receiving a request, rarpd maps the target hardware address to an IP address via its name, which must be present in both the ethers(5) and hosts(5) databases. If a host does not exist in both databases the translation cannot proceed and a reply will not be sent.

In normal operation, rarpd forks a copy of itself and runs in the background. Anomalies and errors are reported via syslog(3).

# OPTIONS

-a
  Listen on all the Ethernets attached to the system. If ‘-a’ is omitted, an interface must be specified.
-d
  Run in debug mode, with all the output to stderr. This option implies the -f option.
-f
  Run in the foreground.
-l
  Log all requests to syslog.

# FILES
