SYNOPSIS
/usr/opt/obsolete/usr/sbin/bootpd [-c chdir-path] [-ttimeout] [-d
debug-level] [configfile [dumpfile]]
OPTIONS
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.
DESCRIPTION
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.
RESTRICTIONS
Individual host entries must not exceed 1024 characters.
You cannot run bootpd and joind on the same system at the same time.
