NAME    [Toc]    [Back]

     rarpd - reverse ARP daemon

SYNOPSIS    [Toc]    [Back]

     rarpd [-adflt] [interface]

DESCRIPTION    [Toc]    [Back]

     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.

     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, an interface 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 requests if if the server  (i.e.,  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 hexidecimal
(only the
             first 8 characters of filenames are checked).
