RARPD(8) BSD System Manager's Manual RARPD(8)NAMErarpd - reverse ARP daemon
SYNOPSISrarpd [-adflt] [interface]
DESCRIPTIONrarpd services Reverse ARP requests on the Ethernet connected to
interface. Upon receiving a request, rarpd maps the target hardware ad-
dress 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 data-
bases, the translation cannot proceed and a reply will not be sent.
In normal operation, rarpd forks a copy of itself and runs in the back-
ground. Anomalies and errors are reported via syslog(3).
The options are as follows:
-a Listen on all the Ethernets attached to the system. If -a is om-
itted, an interface must be specified.
-d Run in debug mode, with all the output to stderr. This option im-
plies the -f option.
-f Run in the foreground.
-l Log all requests to syslog(3).
-t Only honour a requests if if the server (i.e., the host that
rarpd is running on) can "boot" the target; that is, if a file or
directory called /tftpboot/ipaddr exists, where ipaddr is the
target IP address expressed in uppercase hexidecimal (only the
first 8 characters of filenames are checked).
