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
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
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 compiled 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 com-
Individual host entries must not exceed 1024 characters.
You cannot run bootpd and joind on the same system at the same time.
