23 \fBin.rarpd\fR starts a daemon that responds to Reverse Address Resolution
24 Protocol (RARP) requests. The daemon forks a copy of itself that runs in
25 background. It must be run as root.
28 RARP is used by machines at boot time to discover their Internet Protocol (IP)
29 address. The booting machine provides its Ethernet address in a \fBRARP\fR
30 request message. Using the \fBethers\fR and \fBhosts\fR databases,
31 \fBin.rarpd\fR maps this Ethernet address into the corresponding \fBIP\fR
32 address which it returns to the booting machine in an \fBRARP\fR reply message.
33 The booting machine must be listed in both databases for \fBin.rarpd\fR to
34 locate its \fBIP\fR address. \fBin.rarpd\fR issues no reply when it fails to
35 locate an \fBIP\fR address.
38 \fBin.rarpd\fR uses the \fBSTREAMS-based\fR Data Link Provider Interface (DLPI)
39 message set to communicate directly with the datalink device driver.
43 The following options are supported:
50 Get the list of available network interfaces from \fBIP\fR using the
51 \fBSIOCGIFADDR\fR ioctl and start a \fBRARP\fR daemon process on each interface
61 Print assorted debugging messages while executing.
66 \fBExample 1 \fRStarting An \fBin.rarpd\fR Daemon For Each Network Interface

70 The following command starts an \fBin.rarpd\fR for each network interface name
71 returned from \fB/dev/ip:\fR

82 \fBExample 2 \fRStarting An \fBin.rarpd\fR Daemon On The Device \fB/dev/le\fR

86 The following command starts one \fBin.rarpd\fR on the device \fB/dev/le\fR
87 with the device instance number \fB0\fR.

157 The \fBin.rarpd\fR service is managed by the service management facility,
158 \fBsmf\fR(5), under the service identifier:
169 Administrative actions on this service, such as enabling, disabling, or
170 requesting restart, can be performed using \fBsvcadm\fR(1M). The service's
171 status can be queried using the \fBsvcs\fR(1) command.
