RARP(8)			   Linux Programmer's Manual		       RARP(8)

NAME
       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 hostname 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 let‐
       ters 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 Ethernet 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) command.

FILES
       /etc/ethers,
       /etc/nsswitch.conf,
       /tftpboot

SEE ALSO
