NAME #
rarpd - reverse ARP daemon
SYNOPSIS #
rarpd [-adflt] if0 [… ifN]
DESCRIPTION #
rarpd services Reverse ARP requests on the Ethernet connected to the specified interfaces. 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).
The options are as follows:
-a
Listen on all the Ethernets attached to the system. If -a is omitted, a list of interfaces 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(3).
-t
Only honour a request if the server (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 hexadecimal (only the first 8 characters of filenames are checked).
FILES #
/etc/ethers
Ethernet host name database.
/etc/hosts
Host name database.
