NAME

6       rarpd - Reverse Address Resolution Protocol (RARP) daemon
7

SYNOPSIS

9       rarpd [-aAvde] [-b bootdir ] [ interface ]
10

DESCRIPTION

12       Rarpd  is  a  daemon  which responds to RARP requests.  RARP is used by
13       some machines at boot time to discover their IP address.  They  provide
14       their  Ethernet  address and rarpd responds with their IP address if it
15       finds it in the  ethers  database  (either  /etc/ethers  file  or  NIS+
16       lookup) and using DNS lookup if ethers database contains a hostname and
17       not an IP address.  By default rarpd also checks if  a  bootable  image
18       with  a name starting with the IP address in hexadecimal uppercase let‐
19       ters is present in the TFTP boot directory (usually /tftpboot )  before
20       it decides to respond to the RARP request.
21

OPTIONS

23       -a     Do not bind to the interface.
24
25       -A     Respond to ARP as well as RARP requests.
26
27       -v     Tell the user what is going on by being verbose.
28
29       -d     Debugging mode. Do not detach from the tty.
30
31       -e     Skip the check for bootable image in the TFTP boot directory. If
32              not present, then even if the Ethernet address is present in the
33              ethers  database but the bootable image for the resolved IP does
34              not exist, rarpd will not respond to the request.
35
36       -b bootdir
37              Use bootdir instead of the default /tftpboot as  the  TFTP  boot
38              directory for bootable image checks.
