rarpd8

Usage

Overview

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.
