rarpd - answer RARP REQUESTs
arping [-aAvde] [-b bootdir] [interface]
Listens RARP requests from clients. Provided MAC address of client is
found in /etc/ethers database and obtained host name is resolvable to
an IP address appropriate for attached network, rarpd answers to
client with RARPD reply carrying an IP address.
To allow multiple boot servers on the network rarpd optionally checks
for presence Sun-like bootable image in TFTP directory. It should
have form Hexadecimal_IP.ARCH, f.e. to load sparc 193.233.7.98
C1E90762.SUN4M is linked to an image appropriate for SUM4M in
directory /etc/tftpboot.
This facility is deeply obsoleted by BOOTP and later DHCP protocols.
However, some clients really still need this to boot.
-a
Listen on all the interfaces. Currently it is an internal option,
its function is overridden with interface argument. It should not
be used.
-A
Listen not only RARP but also ARP messages, some rare clients use
ARP by some unknown reason.
-v
Be verbose.
-d
Debug mode. Do not go to background.
-e
Do not check for presence of a boot image, reply if MAC address
resolves to a valid IP address using /etc/ethers database and
DNS.
-b bootdir
TFTP boot directory. Default is /etc/tftpboot
arping(8), tftpd(8).
rarpd was written by Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>.
rarpd requires CAP_NET_RAW capability to listen and send RARP and ARP
packets. It also needs CAP_NET_ADMIN to give to kernel hint for ARP
resolution; this is not strictly required, but some (most of, to be
more exact) clients are so badly broken that are not able to answer
ARP before they are finally booted. This is not wonderful taking into
account that clients using RARPD in 2002 are all unsupported relic
creatures of 90's and even earlier.
rarpd is part of iputils package.
