rarpd - reverse ARP daemon
rarpd [-adflt] [interface]
rarpd 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).
