NAME [Toc] [Back]
rarpd - Reverse Address Resolution Protocol daemon
SYNOPSIS [Toc] [Back]
rarpd [-d] [-f config_file] [interface_name]
DESCRIPTION [Toc] [Back]
rarpd, the Reverse Address Resolution Protocol daemon, implements the
server portion of the Reverse Address Resolution Protocol . 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.
-d Print debugging information.
-f config_file 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.
# hardware addr IP addr
# ethernet clients
# 100VG clients
# FDDI clients
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
SIGINT Dumps current data base and cache to /var/tmp/rarpd.db.
RETURN VALUE [Toc] [Back]
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 [Toc] [Back]
1. The rarpd daemon supports only ethernet, 100VG and FDDI network
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.
