rpld.conf(4)                     File Formats                     rpld.conf(4)

       rpld.conf - Remote Program Load (RPL) server configuration file


       The   /etc/rpld.conf  file  contains  the configuration information for
       operation of  rpld, the RPL-based network boot server.  It  is  a  text
       file containing keyword-value pairs and comment.

       The keyword-value pairs specify the value to use for parameters used by
       the RPL server.  Comments can be entered by starting the line using the
       # character.  The user can add comments to the file for customized con-

       Alternate RPL server configuration files can be specified when  running
       the RPL server by supplying a configuration file similar to the default
       configuration file.

       All keywords are case-sensitive.  Not all  keywords  must  be  present.
       (However,  note  that  the  end  keyword at the end of the file must be
       present.) If a keyword is not present, internal defaults, which are the
       default  values  described  here, will be used. Keyword-value pairs are
       specified by:

       keyword = value

       DebugLevel      Specify the number of error, warning,  and  information
                       messages  to  be generated while the RPL server is run-
                       ning.  The valid range is 0-9.  A value of 0  means  no
                       message  at  all,  while a value of 9 will generate the
                       most messages.
                        The default is 0. Note that it is best  to  limit  the
                       value  to  8  or  below; use of level 9 may generate so
                       many debug messages that the  performance  of  the  RPL
                       server may be impacted.

       DebugDest       A  numeric  value specifying where to send the messages

                       0 = standard output
                       1 = syslogd
                       2 = log file

                       The default is 2.

       MaxClients      A numeric value specifying the maximum number of simul-
                       taneous network boot clients to be in service.  A value
                       of -1 means unlimited except where system resources  is
                       the  limiting  factor.   Any  positive value will set a
                       limit on the number of clients to be in service at  the
                       same  time  unless  system resource constraints come in
                       before the limit.  The default is -1.

       BackGround      A numeric  value  indicating  whether  the  RPL  server
                       should  run  in the background or not. A 0 means run in
                       the background and a 1 means do not run  in  the  back-
                        The  difference  is whether the server will relinquish
                       the controlling terminal or not. The default is 1.

       FrameSize       The default size of data frames  to  be  used  to  send
                       bootfile  data  to the network boot clients.  This size
                       should not exceed the limits imposed by the  underlying
                       physical media. For  ethernet/802.3, the maximum physi-
                       cal frame size is 1500 octets.  The  default  is  1500.
                       Note  that  the protocol overhead of LLC1 and RPL is 32
                       octets, resulting in a  maximum  data  length  of  1468

       LogFile         The  log  file  to  which  messages  will  be  sent  if
                       DebugDest is set to 2 (the default).  The default  file
                       is  var/spool/rpld.log.

       StartDelay      The initial delay factor to use to control the speed of
                       downloading.  In the default  mode  of  operation,  the
                       downloading  process  does  not  wait  for  a  positive
                       acknowledgment from the client  before  the  next  data
                       frame  is  sent.  In the case of a fast server and slow
                       client,  data  overrun  can  result  and  requests  for
                       retransmission will be frequent.  By using a delay fac-
                       tor, the speed of data transfer is controlled to  avoid
                       retransmission  requests.   Note that the unit of delay
                       is machine dependent and bears no correlation with  the
                       actual time delayed.

       DelayGran       Delay  granularity.  If the initial delay factor is not
                       suitable and the rate of downloading is either too fast
                       or  too  slow, retransmission requests from the clients
                       will be used to adjust the delay factor  either  upward
                       (to  slow  down the data rate) or downward (to speed up
                       the data rate).  The delay granularity is used  as  the
                       delay delta for adjustment.

       end             Keyword at the end of the file.  It must be present.
