       bootpd - Internet Boot Protocol (BOOTP) server

       /usr/opt/obsolete/usr/sbin/bootpd   [-c	 chdir-path]  [-ttimeout]  [-d
       debug-level] [configfile [dumpfile]]

       Sets the current directory used by a bootpd process while checking  the
       existence  and  size  of client boot files.  This is useful when client
       boot files are specified as relative pathnames and the  bootpd  process
       needs  to  use the same current directory as the TFTP server (typically
       /tftpboot).  Sets the debug-level variable that controls the number  of
       debugging  messages  generated.	 For  example, -d 4 sets the debugging
       level to 4.  Valid entries are 1 to 4, where 1 specifies lower level of
       messages	 and  4 the highest.  Specifies the timeout value (in minutes)
       that a bootpd process waits for a BOOTP packet before exiting.	If  no
       packets are received for timeout minutes, the program exits.  A timeout
       value of zero means that a bootpd process will wait forever.  When  the
       bootpd  daemon  is  not	started using the inetd daemon, this option is
       forced to zero.

       The bootpd daemon  implements  an  Internet  Boot  Protocol  server  as
       defined	in RFC 951, RFC 1532, and RFC 1533. In order to use the bootpd
       daemon, you must install the Obsolete  Commands	and  Utilities	subset
       (OSFOBSOLETExxx).   It  can be started by the /usr/sbin/inetd daemon by
       including the following line in the /etc/inetd.conf file: bootps	 dgram
       udp wait root /usr/sbin/bootpd bootpd

       This  causes bootpd to be started only when a boot request arrives.  If
       bootpd does not receive another boot request within fifteen minutes  of
       the  last  one it received, it exits to conserve system resources.  The
       -t option can be used to specify a different timeout value  in  minutes
       (for example, -t20).  A timeout value of zero means forever.

       To run the bootpd daemon, you must also run the tftpd daemon.

       Upon startup, bootpd first reads its configuration file, /etc/bootptab,
       and then begins listening for BOOTREQUEST packets.  See bootptab(4) for
       a  description  of  the	configuration file. The bootpd daemon looks in
       /etc/services to find the port numbers it should use.  Two entries  are
       extracted: The bootp server listening port The destination port used to
       reply to clients

       If the port numbers cannot be determined this way, they are assumed  to
       be 67 for the server and 68 for the client.

       The  bootpd  daemon  rereads  its configuration file when it receives a
       hangup signal, SIGHUP, or when it receives a bootp request  packet  and
       detects	that  the file has been updated.  Hosts can be added, deleted,
       or modified when the configuration file is reread.  If bootpd  is  com‐
       piled with the -DDEBUG option, receipt of a SIGUSR1 signal causes it to
       dump its memory-resident database to the /usr/adm/bootpd.dump  file  or
       dumpfile specified in the command line.

       Individual host entries must not exceed 1024 characters.

       You cannot run bootpd and joind on the same system at the same time.
