rarpd - Reverse Address Resolution Protocol (RARP) daemon
SYNOPSIS
rarpd [-aAvde] [-b bootdir ] [ interface ]
DESCRIPTION
Rarpd is a daemon which responds to RARP requests. RARP
is used by some machines at boot time to discover their IP
address. They provide their Ethernet address and rarpd
responds with their IP address if it finds it in the
ethers database (either /etc/ethers file or NIS+ lookup)
and using DNS lookup if ethers database contains a host
name and not an IP address. By default rarpd also checks
if a bootable image with a name starting with the IP
address in hexadecimal uppercase letters is present in the
TFTP boot directory (usually /tftpboot ) before it decides
to respond to the RARP request.
OPTIONS
-a Do not bind to the interface.
-A Respond to ARP as well as RARP requests.
-v Tell the user what is going on by being verbose.
-d Debugging mode. Do not detach from the tty.
-e Skip the check for bootable image in the TFTP boot
directory. If not present, then even if the Ether
net address is present in the ethers database but
the bootable image for the resolved IP does not
exist, rarpd will not respond to the request.
-b bootdir
Use bootdir instead of the default /tftpboot as the
TFTP boot directory for bootable image checks.
OBSOLETES
This rarpd obsoletes kernel rarp daemon present in Linux
kernels up to 2.2 which was controlled by the rarp(8) com
mand.
