NAME    [Toc]    [Back]

     rarpd - DARPA Reverse Address Resolution Protocol daemon

SYNOPSIS    [Toc]    [Back]

     /usr/etc/rarpd [-d] [-l logfile] [interface ...]

DESCRIPTION    [Toc]    [Back]

     rarpd responds to Reverse Address Resolution Protocol (Reverse ARP, RARP)
     requests.	It puts	itself in the background, and requires root
     privileges.

     The Reverse ARP protocol is used by systems at boot time to discover
     their 32-bit Internet Protocol (IP) address given their 48-bit Ethernet
     address.  In order	for a RARP request to be answered, the requesting
     system's name-to-IP-address entry must exist in the /etc/hosts file and
     its name-to-Ethernet-address entry	must exist in the /etc/ethers file.
     Note that if the server running rarpd is using the	network	information
     service (NIS), the	server's /etc files are	ignored	and the	appropriate
     NIS maps are queried.

     Normally rarpd serves all configured IP interfaces	which support
     broadcasting.  Optional interface arguments restrict service to only
     those interfaces.	The -d option causes rarpd to run in the foreground
     and log diagnostics on its	standard error output.	The -l option causes
     rarpd to record requests in logfile.
