System administration command. Respond to Reverse Address Resolution Protocol (RARP) requests. Some machines (primarily diskless SUN machines) will use RARP requests at boot time to discover their IP address and retrieve boot images. The request contains the booting machine's Ethernet address, and rarpd tells it which IP to use. To answer requests, rarpd checks the ethers database (either the /etc/ethers file, or read from NIS+) and performs DNS lookups as needed. rarpd will respond to RARP requests only from machines for which it has a bootable image, usually stored in the TFTP boot directory /tftpboot. The daemon will bind to the given interface if specified. This daemon replaces the kernel-based RARP support found in kernels previous to 2.2.
Do not bind to the specified interface.
Look for boot images in the specified directory instead of the default /tftpboot.
Do not detach and run in daemon mode. Used for debugging.
Answer requests without checking the TFTP boot directory.
Respond to ARP requestes as well as RARP requests.
