in.rarpd


NAME
     in.rarpd, rarpd - DARPA Reverse Address Resolution  Protocol
     server

SYNOPSIS
     /usr/sbin/in.rarpd [-d] -a

     /usr/sbin/in.rarpd [-d] device unit

DESCRIPTION
     in.rarpd starts a daemon that responds  to  Reverse  Address
     Resolution Protocol (RARP) requests. The daemon forks a copy
     of itself that runs in background. It must be run as root.

     RARP is used by machines at  boot  time  to  discover  their
     Internet Protocol (IP) address. The booting machine provides
     its Ethernet address in a RARP request  message.  Using  the
     ethers  and  hosts  databases,  in.rarpd  maps this Ethernet
     address into the corresponding IP address which  it  returns
     to the booting machine in an RARP reply message. The booting
     machine must be listed in both  databases  for  in.rarpd  to
     locate  its  IP  address.  in.rarpd  issues no reply when it
     fails to locate an IP address.

     in.rarpd uses the STREAMS-based Data Link Provider Interface
     (DLPI) message set to communicate directly with the datalink
     device driver.

OPTIONS
     The following options are supported:

     -a       Get the list of available network  interfaces  from
              IP  using  the  SIOCGIFADDR  ioctl and start a RARP
              daemon process on each interface returned.



     -d       Print assorted debugging messages while executing.




EXAMPLES
     Example 1: Starting An  in.rarpd  Daemon  For  Each  Network
     Interface Name Returned From /dev/ip:

     The following command starts an in.rarpd  for  each  network
     interface name returned from /dev/ip:

     example# /usr/sbin/in.rarpd -a


     Example 2: Starting An in.rarpd Daemon On The Device /dev/le
     With The Device Instance Number  0

     The following command starts  one  in.rarpd  on  the  device
     /dev/le with the device instance number 0.

     example# /usr/sbin/in.rarpd le 0
