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
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.

41 This rarpd obsoletes kernel rarp daemon present in Linux kernels up to
42 2.2 which was controlled by the rarp(8) command.
