rarpd - Reverse Address Resolution Protocol (RARP) daemon
rarpd [-aAvde] [-b bootdir ] [ interface ]
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 letters is present in the TFTP boot directory (usually
/tftpboot ) before it decides to respond to the RARP request.
-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.
Use bootdir instead of the default /tftpboot as the TFTP boot directory for
bootable image checks.
This rarpd obsoletes kernel rarp daemon present in Linux kernels up to 2.2 which was con-
trolled by the rarp(8) command.
