Reverse Address Resolution Protocol daemon

rarpd starts a daemon that responds to Reverse
Address Resolution Protocol (RARP) requests. The
daemon forks a copy of itself, and requires root
Machines use RARP at boot time to discover their
(32 bit) IP address given their (48 bit) Ethernet
address. The booting machine sends its Ethernet address in
a RARP request message. For the request to be
answered, a machine's name-to-IP-address entry
must exist in the /etc/hosts file or must be
available from the domain name server and its
name-to-Ethernet-address entry must exist in the
/etc/ethers file. Using the above two sources,
rarpd maps this Ethernet address into the
corresponding IP address. Furthermore, the
server that runs this daemon must have entries in both
