RARP(7P) Protocols RARP(7P)


NAME


rarp, RARP - Reverse address resolution protocol

DESCRIPTION


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(1M) 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 retry a maximum of five times with a
eight second wait between retries.
