RARP(4P) Protocols RARP(4P)

rarp, RARP - Reverse address resolution protocol

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(8). in.rarpd(8) 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.
