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 data-
     bases, 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 direc-
     tory /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
