You use the RARP protocol to map dynamically between the Internet Protocol
(IP) and network interface MAC addresses. RARP is often used to boot a Solaris
client. RARP clients include the SPARC boot PROM, x86 boot floppy, SunOS kernel,
and ifconfig(1M). in.rarpd(7d) provides
the server-side implementation.
RARP request timeout behavior in application-layer clients is governed
by the /etc/inet/rarp default file. To tune the number
of retries an application attempts before giving up, set the RARP_RETRIES variable in /etc/inet/rarp. If the file is not
present or RARP_RETRIES is not initialized within it, applications
will retry a maximum of five times with a five second wait between retries.
