+.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
+.It Fl a
+Listen on all the Ethernets attached to the system.
+If 
+.Sq Fl a 
+is omitted, an interface must be specified.
+.It Fl d

+This option implies the 
+.Fl f
