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 data-
     bases 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

     /etc/ethers
     /etc/hosts
