.SH DESCRIPTION
|
||
|
.LP
|
||
|
.I Rarpd
|
||
|
services Reverse ARP requests on the Ethernet connected to
|
||
|
.I interface.
|
||
|
Upon receiving a request,
|
||
|
.Irarpd
|
||
|
maps the target hardware address to an IP address via its name, which
|
||
|
must be present in both the
|
||
|
.I ethers(5)
|
||
|
and
|
||
|
.I hosts(5)
|
||
|
databases.
|
||
|
If a host does not exist in both databses, the translation cannot
|
||
|
proceed and a reply will not be sent.
|
||
|
|
||
|
Additionally, a request is honored only if the server
|
||
|
(i.e., the host that rarpd is running on)
|
||
|
can "boot" the target; that is, if the directory
|
||
|
/tftpboot/\fIipaddr\fP
|
||
|
exists, where \fIipaddr\fP is the target IP address.
|
||
|
|
||
|
In normal operation,
|
||
|
.I rarpd
|
||
|
forks a copy of itself and runs in
|
||
|
the background. Anomalies and errors are reported via
|
||
|
.I syslog(3).

||

.SH BUGS
|
||
|
You must have the Berkeley Packet Filter configured into your kernel
|
||
|
in order to use this program. This isn't really a bug, but it isn't
|
||
|
exactly a feature either.
