RARPD(8) BSD System Manager's Manual RARPD(8)NAMErarpd — Reverse ARP Daemon
SYNOPSISrarpd [-adf] [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 data‐
bases, the translation cannot proceed and a reply will not be sent.
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 direc‐
tory /tftpboot/ipaddr exists, where is the target IP address.
In normal operation, rarpd forks a copy of itself and runs in the back‐
ground. 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.
FILES
