NAME
rarpd —
Reverse ARP Daemon
SYNOPSIS
rarpd |
[-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 databases, 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 directory /tftpboot/ipaddr exists, where is the target IP address.
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
-foption. -f- Run in the foreground.
FILES
- /etc/ethers
- /etc/hosts
- /tftpboot
