       bootpd - Server to help boot diskless clients

       /usr/etc/bootpd [ -d ] [ -i ]

       The  server  is for the Internet BOOTP protocol (a UDP-based protocol).
       This allows a diskless machine to find out its  Internet	 address,  the
       address of a bootserver, and the name of a file to boot.

       The  server  is	either	started from or from If is started from the -i
       flag must be supplied by The server reads its configuration file,  when
       it starts up. When a new request arrives, checks to see if the file has
       been modified, and if so, reads it again.

       If started by waits until no new requests arrive for one minute.	  This
       limits the overhead of restarting the daemon without tying up a process
       slot when nothing is happening.	The following is  an  example  of  the
       format of the configuration file:
       # /etc/bootptab:	 database for bootp server (/usr/etc/bootpd)
       # Blank lines and lines beginning with '#' are ignored.
       # home directory


       # default bootfile


       # end of first section


       # The remainder of this file contains one line per client
       # interface with the information shown by the table headings
       # below. The host name is also tried as a suffix for the
       # bootfile when searching the home directory (that is,
       # host	      htype haddr	  iaddr		 bootfile

       hostx	      1 02:60:8c:06:35:05	 ultrix
       hosty	      1 02:07:01:00:30:02	 vms
       hostz	      1 02:60:8c:00:77:78	 lps40
       node1	      1 02:60:8c:00:99:47	 tops20
       The  first  two	lines  specify	the  home  (default) directory and the
       default bootfile, respectively.	A line starting with two percent signs
       (%%) separates these first lines from the host information table, which
       contains an entry for each bootable host.

       You should start with a configuration file similar to this and edit the
       host  entries to correspond to your local systems.  The host field does
       not have to be a formal host name; it is used for identification in the
       log file and also as a possible extension to the bootfile name.

       The  is always 1 and corresponds to the hardware type assigned Ethernet
       by the Assigned Numbers RFC.  The field can use a period (.), a	hyphen
       (-),  or	 a colon (:) as separators.  The entry is the file used if the
       client does not know the name of the file it wants to  boot.   This  is
       frequently the case when a diskless workstation is booted.

       Be  sure	 to  enter  the	 current Ethernet address for each host in the
       field, because a request for an address that is not the current	etherÔÇÉ
       net  address causes the original translation to be lost.	 In turn, this
       condition causes a temporary outage for TCP/IP connections such as and
