rarpd(1M)rarpd(1M)NAME
rarpd - Reverse Address Resolution Protocol daemon
SYNOPSIS
config_file] [interface_name]
DESCRIPTION
the Reverse Address Resolution Protocol daemon, implements the server portion of the Reverse Address Resolution Protocol [1]. It responds
to RARP requests providing the requested client IP address. Rarpd can be started during boot-time initialization. To do so, set the vari-
able with in
Options are:
Print debugging information.
Use the specified
config_file database instead of
interface_name Respond to requests over just this interface.
The configuration file database contains hardware address to IP address mappings. Other than comment lines (which begin with a '#') and
blank lines, all lines are considered client entries. A client entry is of the form:
hardware_address WHITE_SPACE ip_address
where hardware_address consists of (colon-separated hexadecimal bytes, and ip_address consists of (dot-seperated decimal bytes. For exam-
ple:
#
# hardware addr IP addr
#
# ethernet clients
08:00:09:26:ec:19 15.13.136.68
08:00:09:17:0a:93 15.13.136.74
#
# 100VG clients
08:00:09:63:5d:f5 190.20.30.103
#
# FDDI clients
08:00:09:09:53:4c 192.20.30.98
There must be exactly 6 hardware address bytes. There must be exactly 4 protocol address bytes.
The following signals have the specified effect when sent to the process using the kill(1) command:
Causes server to read the config file and reload database.
Dumps current data base and cache to
RETURN VALUE
Exit status is 1 if the command fails, and error messages are written to stderr and/or syslog. Typically, the daemon will continue answer-
ing requests until externally interrupted.
LIMITATIONS
1. The daemon supports only ethernet, 100VG and FDDI network interfaces.
2. The daemon supports only 4 byte Internet Protocol addresses.
3. The and programs cannot be run on the same interface at the same time.

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
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 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
FILES
/etc/ethers File or other source, as specified by nsswitch.conf(4).

NOTES
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 ser-
vice's status can be queried using the svcs(1) command.
