System Administration Commands in.rarpd(1M)
NAME
in.rarpd, rarpd - DARPA Reverse Address Resolution Protocol
serverSYNOPSIS
/usr/sbin/in.rarpd [-d] -a
/usr/sbin/in.rarpd [-d] device unit
DESCRIPTION
in.rarpd starts a daemon that responds to Reverse Address
Resolution Protocol (RARP) requests. The daemon forks a copy of itself that runs in background. It must be run as root. RARP is used by machines at boot time to discover their Internet Protocol (IP) address. The booting machine provides its Ethernet address in a RARP request message. Using theethers and hosts databases, in.rarpd maps this Ethernet
address into the corresponding IP address which it returns to the booting machine in an RARP reply message. The bootingmachine must be listed in both databases for in.rarpd to
locate its IP address. in.rarpd issues no reply when it
fails to locate an IP address.in.rarpd uses the STREAMS-based Data Link Provider Interface
(DLPI) message set to communicate directly with the datalink device driver. OPTIONS The following options are supported:-a Get the list of available network interfaces from IP
using the SIOCGIFADDR ioctl and start a RARP daemon process on each interface returned.-d Print assorted debugging messages while executing.

facility, smf(5), under the service identifier: svc:/network/rarp Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.SunOS 5.11 Last change: 20 Aug 2004 3
