in.rarpd(1M) System Administration Commands in.rarpd(1M)NAME
in.rarpd, rarpd - DARPA Reverse Address Resolution Protocol server
SYNOPSIS
/usr/sbin/in.rarpd [-d] -a
/usr/sbin/in.rarpd [-d] device unit
DESCRIPTIONin.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 Proto‐
col (IP) address. The booting machine provides its Ethernet address in
a RARP request message. Using the ethers 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 booting
machine 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.
EXAMPLES
Example 1: Starting An in.rarpd Daemon For Each Network Interface Name
Returned From /dev/ip:
The following command starts an in.rarpd for each network interface
name returned from /dev/ip:
example# /usr/sbin/in.rarpd -a
Example 2: Starting An in.rarpd Daemon On The Device /dev/le With The
Device Instance Number 0
The following command starts one in.rarpd on the device /dev/le with
the device instance number 0.
example# /usr/sbin/in.rarpd le 0

The in.rarpd service is managed by the service management 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.
