.Sh NAME
|
|
.Nm rarpd
|
|
.Nd Reverse ARP Daemon
|
|
.Sh SYNOPSIS
|
|
.Nm rarpd
|
|
.Op Fl adf
|
|
.Op Ar interface
|
|
.Sh DESCRIPTION
|
|
.Nm Rarpd
|
|
services Reverse ARP requests on the Ethernet connected to
|
|
.Ar interface.
|
|
Upon receiving a request,
|
|
.Nm rarpd
|
|
maps the target hardware address to an IP address via its name, which
|
|
must be present in both the
|
|
.Xr ethers 5
|
|
and
|
|
.Xr hosts 5
|
|
databases.
|
|
If a host does not exist in both databases, the translation cannot
|
|
proceed and a reply will not be sent.
|
|
.\" .Pp
|
|
.\" 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
|
|
.\" .Pa /tftpboot/ Ns Em ipaddr
|
|
.\" exists, where
|
|
.\" .Rm ipaddr
|
|
.\" is the target IP address.
|
|
.Pp
|
|
In normal operation,
|
|
.Nm rarpd
|
|
forks a copy of itself and runs in
|
|
the background. Anomalies and errors are reported via
|
|
.Xr syslog 3 .
|
|
.Sh OPTIONS
|
|
.Bl -tag -width indent
