.Sh NAME

.Nm rarpd
|
|
.Nd Reverse ARP Daemon
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl adfl
|
|
.Op Ar interface
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
services Reverse ARP requests on the Ethernet connected to
|
|
.Ar interface .
|
|
Upon receiving a request,
|
|
.Nm
|
|
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
|
|
.\" (the host that rarpd is running on)
|
|
.\" can `boot' the target.
|
|
.\" .Pp
|
|
.\" To be considered able to boot the target the server must have
|
|
.\" a file or directory
|
|
.\" .Pa /tftpboot/ Ns Em ipaddr
|
|
.\" where
|
|
.\" .Pa ipaddr
|
|
.\" is the target IP address as an eight digit hexadecimal string.
|
|
.\" For example, the IP address 203.8.3.18 is represented as
|
|
.\" .Sq CB080312 .
|
|
.Pp
|
|
In normal operation,
|
|
.Nm
|
|
forks a copy of itself and runs in
|
|
the background. Anomalies and errors are reported via
|
|
.Xr syslog 3 .
