NAME    [Toc]    [Back]

     rbootd - HP remote boot server

SYNOPSIS    [Toc]    [Back]

     rbootd [-ad] [-i interface] [config_file]

DESCRIPTION    [Toc]    [Back]

     The rbootd utility  services  boot  requests  from  HewlettPackard workstations
 over a local area network.  All boot files must reside
in the boot
     file directory; further, if a client supplies path  information in its
     boot  request, it will be silently stripped away before processing.  By
     default, rbootd only  responds  to  requests  from  machines
listed in its
     configuration file.

     The options are as follows:

     -a      Respond to boot requests from any machine.  The configuration
             file is ignored if this option is specified.

     -d      Run rbootd in debug mode.  Packets sent and received
are displayed
 to the terminal.

     -i interface
             Service  boot  requests  on specified interface.  If
             rbootd searches the system interface  list  for  the
lowest numbered,
  configured ``up'' interface (excluding loopback).  Ties
             are broken by choosing the earliest match.

     Specifying config_file on the command line causes rbootd  to
use a different
 configuration file from the default.

     The  configuration  file  is a text file where each line describes a particular
 machine.  A line must start with a  machine's  Ethernet
address followed
  by  an optional list of boot file names.  An Ethernet
address is
     specified in hexadecimal with each of its six  octets  separated by a
     colon.  The boot file names come from the boot file directory.  The Ethernet
 address and boot file(s) must be separated by  whitespace and/or
     comma  characters.   A  pound sign causes the remainder of a
line to be ignored.

     Here is a sample configuration file:

     # ethernet addr     boot file(s)        comments
     08:00:09:0:66:ad    SYSHPBSD            # snake (4.3BSD)
     08:00:09:0:59:5b                        # vandy (anything)
     8::9:1:C6:75        SYSHPBSD,SYSHPUX    # jaguar (either)

     rbootd logs status and  error  messages  via  syslog(3).   A
startup message
     is always logged, and in the case of fatal errors (or deadly
signals) a
     message is logged announcing the server's  termination.   In
general, a
     non-fatal error is handled by ignoring the event that caused
it (e.g., an
     invalid Ethernet address in the config file causes that line
to be invalidated).

     The following signals have the specified effect when sent to
the server
     process using the kill(1) command:

             SIGHUP   Drop all active connections  and  reconfigure.

             SIGUSR1   Turn  on  debugging, do nothing if already

             SIGUSR2  Turn off debugging, do nothing  if  already

FILES    [Toc]    [Back]

     /dev/bpf#            packet-filter device
     /etc/rbootd.conf     configuration file
     /tmp/rbootd.dbg      debug output
     /usr/mdec/rbootd     directory containing boot files
     /var/run/rbootd.pid  process ID

SEE ALSO    [Toc]    [Back]

     kill(1), socket(2), signal(3), syslog(3)

BUGS    [Toc]    [Back]

     If  multiple servers are started on the same interface, each
will receive
     and respond to the same boot packets.
