NAME

bootpd - Internet Boot Protocol (BOOTP) server  

SYNOPSIS

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

FLAGS

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 flag 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 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 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.
