-.TH RARPD 8
-.SH NAME
-rarpd \- reverse address resolution protocol daemon
-.SH SYNOPSIS
-.B rarpd
-.RB [ \-d [\fIlevel\fR]]
-.I network-name
-\&...
-.SH DESCRIPTION
-.de SP
-.if t .sp 0.4
-.if n .sp
-..
-.B Rarpd
-listens on the given networks for broadcast packets asking for reverse address
-resolution.  These packets are sent by hosts at boot time to find out their
-IP address.
-.B Rarpd
-looks up the six octet ethernet number in the
-.B /etc/ethers
-file finding a host name.  This name is translated to the IP address of the
-host by a DNS lookup.  The IP address is then sent to the host.
-.PP
-Under MINIX 3 the program forks as needed to give each network its own server.
-Under Minix-vmd all networks are handled in the same program using async I/O.
-.SS "Private Ethernet Addresses"
-For VU practical work, where students have to create their own IP stack
-starting at the bottom with RARP, this implementation recognizes Ethernet
-addresses starting with octet 0x76 as special.  The next octet is used as a
-additional host number and the next and last four octets as an IP address
-that this Ethernet address is additional for.  The IP address is translated
-back to a name, and the first component of that name gets a dash and the
-additional host number added to it.  That hostname is then looked up and its
-IP address returned in a RARP reply.  Example:
-.PP
-.RS
-.ta +\w'flotsam-3.example.commmm'u
-76:3:c0:a8:e7:fa	Additional 3, IP 192.168.231.250
-.SP
-flotsam.example.com	Reverse lookup on 192.168.231.250
-.SP
-flotsam-3.example.com	Splicing in additional number
-.SP
-192.168.231.42		Forward lookup
-.RE
-.PP
-In this example a RARP query for 76:3:c0:a8:e7:fa gets 192.168.231.42 as reply.
-.SH OPTIONS
-.TP
-.BR \-d [\fIlevel\fP]
-Turns on debugging messages at the given level, by default 1.  At level 1 you
-will be shown what answers are sent, and at level 2 or higher you will be told
-about queries from unknown hosts or host on the wrong network.
-The debug level can also be increased by 1 at runtime by sending signal
-.B SIGUSR1
-or turned off (set to 0) with
-.BR SIGUSR2 .
-.SH "SEE ALSO"
-.BR ifconfig (8),
-.BR ethers (5),
-.BR hosts (5),
-.BR inet (8),
-.BR boot (8),
-.BR dhcpd (8),
-.BR irdpd (8),
-.BR inetd (8),
-.BR nonamed (8).
-.SH NOTES
-A "network name" is the device name of the IP device of a network, i.e.
-.BR ip0 ,
-.BR ip1 ", ..."
-.PP
-The RARP protocol has gone out of fashion in favour of DHCP.
