.SH NAME

rarpd \- answer RARP REQUESTs

||
.SH SYNOPSIS
|
||
|
||
\fBarping\fR [ \fB-aAvde\fR] [ \fB-b \fIbootdir\fB\fR] [ \fB\fIinterface\fB\fR]
|
||
|
||
.SH "DESCRIPTION"
|
||
.PP
|
||
Listens
|
||
RARP
|
||
requests from clients. Provided MAC address of client
|
||
is found in \fI/etc/ethers\fR database and
|
||
obtained host name is resolvable to an IP address appropriate
|
||
for attached network, \fBrarpd\fR answers to client with RARPD
|
||
reply carrying an IP address.
|
||
.PP
|
||
To allow multiple boot servers on the network \fBrarpd\fR
|
||
optionally checks for presence Sun-like bootable image in TFTP directory.
|
||
It should have form \fBHexadecimal_IP.ARCH\fR, f.e. to load
|
||
sparc 193.233.7.98 \fIC1E90762.SUN4M\fR is linked to
|
||
an image appropriate for SUM4M in directory \fI/etc/tftpboot\fR.
|
||
.SH "WARNING"
|
||
.PP
|
||
This facility is deeply obsoleted by
|
||
BOOTP
|
||
and later
|
||
DHCP protocols.
|
||
However, some clients really still need this to boot.
|
||
.SH "OPTIONS"
|
||
.TP
|
||
\fB-a\fR
|
||
Listen on all the interfaces. Currently it is an internal
|
||
option, its function is overridden with \fIinterface\fR
|
||
argument. It should not be used.
|
||
.TP
|
||
\fB-A\fR
|
||
Listen not only RARP but also ARP messages, some rare clients
|
||
use ARP by some unknown reason.
|
||
.TP
|
||
\fB-v\fR
|
||
Be verbose.
|
||
.TP
|
||
\fB-d\fR
|
||
Debug mode. Do not go to background.
|
||
.TP
|
||
\fB-e\fR
|
||
Do not check for presence of a boot image, reply if MAC address
|
||
resolves to a valid IP address using \fI/etc/ethers\fR
|
||
database and DNS.
|
||
.TP
|
||
\fB-b \fIbootdir\fB\fR
|
||
TFTP boot directory. Default is \fI/etc/tftpboot\fR
|

\fBrarpd\fR was written by

|
||
.SH "SECURITY"
|
||
.PP
|
||
\fBrarpd\fR requires CAP_NET_RAWIO capability
|
||
to listen and send RARP and ARP packets. It also needs CAP_NET_ADMIN
|
||
to give to kernel hint for ARP resolution; this is not strictly required,
|
||
but some (most of, to be more exact) clients are so badly broken that
|
||
are not able to answer ARP before they are finally booted. This is
|
||
not wonderful taking into account that clients using RARPD in 2002
|
||
are all unsupported relic creatures of 90's and even earlier.
|
||
.SH "AVAILABILITY"
