- .SH NAME
- arpd \- Respond to ARP and RARP requests
- .SH SYNOPSIS
- \fBarpd\fR [\fIoptions\fR]
- .SH OPTIONS
- .IP "\fB\-f \fIfileName\fR" 15
- Use \fIfileName\fR as the configuration file containing host network
- addresses. The file \fB/etc/spritehosts\fR is used by default. If
- this switch is given, \fIfileName\fR must have the same format as
- \fB/etc/spritehosts\fR.
- .IP "\fB\-v\fR" 15
- Verbose: print information on standard output as requests are
- processed.
- .IP "\fB\-help\fR" 15
- Print a summary of the command-line options and exit immediately.

- .SH DESCRIPTION
- .PP
- \fBArpd\fR is a program that responds to requests made under the
- Internet Address Resolution Protocol (ARP) and Reverse Address
- Resolution Protocol (RARP). See RFC826 for details on ARP and
- RFC903 for details on RARP. \fBArpd\fR reads a configuration
- file (normally \fB/etc/spritehosts\fR) that describes a set of
- hosts and their Internet and Ethernet addresses; it will respond
- to ARP and RARP requests for any
- host listed in the file. Note that this differs from the common
- practice in many UNIX systems, where each host responds to ARP
- requests for itself; the norm in Sprite is for a single \fBarpd\fR
- process to handle all requests for the Sprite network.
- .PP
- Although \fBarpd\fR caches the host information in its memory, it
- checks the last-modified time on the configuration file before responding
- to each request, and reloads its internal database if the configuration
- file has changed.
- .PP
- \fBArpd\fR generates diagnostic messages on its standard output.
- Normally, only major errors result in output, but if the \fB\-v\fR
- switch is given, then additional output is generated to describe
- all of the program's actions.
