NAME
 rarpd — Reverse ARP Daemon
SYNOPSIS
| rarpd | [-adfl] [interface [...]] | 
 
DESCRIPTION
 rarpd services Reverse ARP requests on the Ethernet connected to 
interface. Upon receiving a request, 
rarpd maps the target hardware address to an IP address via its name, which must be present in both the 
ethers(5) and 
hosts(5) databases. If a host does not exist in both databases the translation cannot proceed and a reply will not be sent.
In normal operation, rarpd forks a copy of itself and runs in the background.  Anomalies and errors are reported via syslog(3).
 
OPTIONS
- 
-a
- 
Listen on all the Ethernets attached to the system. If ‘-a’ is omitted, an interface must be specified.
- 
-d
- 
Run in debug mode, with all the output to stderr. This option implies the -f option.
- 
-f
- 
Run in the foreground.
- 
-l
- 
Log all requests to syslog.
 
FILES
