BOOTP Service

Overview of bootpd

The Bootstrap Protocol BOOTP allows a client system to get boot information such as its own IP address, the

address of a BOOTP server, and the name of the file it needs to load into its memory and execute to boot the

printer. The bootstrap operation happens in two phases. In the first phase, the BOOTP daemon bootpd

determines the address of a BOOTP server and selects a boot file. In the second phase, the Trivial File Transfer

Protocol daemon tftpd transfers the boot file to the node that requests it.

bootpd Files

There are three files that you will need to configure and use bootpd on your system. These files were copied to

the NET group of the SYS account when you installed or updated to version C.55.00 or later, of MPE/iX.

Table 4-1 briefly describes each one.

Configuring bootpd

To configure bootpd, you will edit three files: the services file, which lists the individual services that

comprise the suite of Internet Services, the inetd configuration file, which informs the Internet daemon

about running bootpd on this host, and the bootpd configuration file, which contains client and relay

information. These tasks are explained in the following sections.

Editing the Services File

The services file associates official service names and aliases with the port number and protocol the services

use. To enable bootpd, you must edit the services file. Perform the following:

1. Open the services file with an MPE text editor. You may edit the /etc/services file from the POSIX

shell or the SERVICES.NET.SYS file from MPE/iX, whichever you prefer. Both names should point to the

same file.

2. Verify that the following lines exist in the file or add them if they do not:

bootps 67/udp # Bootstrap protocol server

Table 4-1 Files for bootpd

File Description

BOOTPD.NET.SYS The program file for bootpd which is linked to the POSIX file

/etc/bootpd.

BPTABSMP.NET.SYS The sample configuration file for bootpd that contains information

about all of the network devices this system can boot. You will copy

this file to BOOTPTAB.NET.SYS, create a symbolic link from the POSIX

file /etc/bootptab to this file, and edit it as necessary.

BOOTPQRY.NET.SYS A program for testing bootpd. You will not need to copy or edit this

file, but you will create a symbolic link from the POSIX file

/etc/bootpquery to BOOTPQRY.NET.SYS.
