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.
