RARPD(8)                    System Manager's Manual                   RARPD(8)

NAME
     rarpd - Reverse ARP Daemon

SYNOPSIS
     rarpd [-adf] [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 back-
     ground.  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.

FILES
     /etc/ethers
     /etc/hosts
