NAME
rarpd - Reverse Address Resolution Protocol daemon
SYNOPSIS
rarpd [-d] [-f config_file] [interface_name]
DESCRIPTION
rarpd, 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 RARPD variable with RARPD=1 in /etc/rc.config.d/netconf.
Options are:
-d Print debugging information.
-f config_file Use the specified config_file database instead of /etc/rarpd.conf.
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 example:
#
# 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 rarpd process using the kill(1) command:
SIGHUP Causes server to read the config file and reload database.
SIGINT Dumps current data base and cache to /var/tmp/rarpd.db.
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 answering requests until externally interrupted.
LIMITATIONS
1) The rarpd daemon supports only ethernet, 100VG and FDDI network interfaces.
2) The rarpd daemon supports only 4 byte Internet Protocol addresses.
3) The rarpd and rarpc programs cannot be run on the same interface at the same time.
