NAME
in.rarpd, rarpd - DARPA Reverse Address Resolution Protocol server
SYNOPSIS
/usr/sbin/in.rarpd [
-d]
-a /usr/sbin/in.rarpd [
-d]
device unitDESCRIPTION
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 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
