- Implement ether_hostton() - Implement ether_aton() - Modify ether_aton() and ether_ntoa() to match the semantics of the SunOS versions of these functions. - Neaten up ether_hostton() and ether_ntohost() a little. - Get rid of ether_print() since it isn't needed for rarpd and it isn't documented as a standard ethers(5) function. rarpd.8: - Make it clear that the 'ipaddr' that rarpd looks for in /tftpboot is actually in hexadecimal (as in /tftpboot/803B4032) since those who are not versed in the black art of system administration are not likely to know this.

.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 hexadecimal.
|
|
|
|
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 OPTIONS
|
|
.LP
|
|
.TP

|
.B \-a

Listen on all the Ethernets attached to the system.
|
|
If `-a' is omitted, an interface must be specified.
|
|
.TP
|
|
.B \-f
|
|
Run in the foreground.

.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.
