RARPD(8)                  BSD 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.

     Additionally, a request is honored only if the server (i.e., the host that rarpd is running on) can
     "boot" the target; that is, if the directory /tftpboot/ipaddr exists, where is the target IP address.

     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.

FILES
     /etc/ethers
     /etc/hosts
     /tftpboot
