BOOTP Service
The bootpd Configuration File
The bootpd Configuration File
When bootpd is started, it reads a configuration file to find out
information about clients and relays, then listens for boot request
packets. By default, bootpd uses the configuration file
/etc/bootptab, but you may specify another configuration file.
The BOOTP server will reread its configuration file and update its
information about new, deleted or modified hosts on two occasions other
than startup: when you send it a SIGHUP signal, or when it receives a
boot request packet and detects that the configuration file has been
edited.
Creating and Linking bootpd Configuration File
You may already have a configuration file for bootpd installed on your
system. If you know that you have such a file, and it is accessible by the
POSIX file name /etc/bootptab you may skip these steps.
If not, follow the steps below to create the file and link to it. If you have
such a file, but are unsure whether or not it is linked, perform step 2
only.
1. Create your own configuration file by using the COPY command to
rename the sample file. Enter:
:COPY BPTABSMP.NET.SYS TO BOOTPTAB.NET.SYS
2. Create a symbolic link from /etc/bootptab in the POSIX name
space to BOOTPTAB.NET.SYS. Enter:
:NEWLINK /etc/bootptab, BOOTPTAB.NET.SYS
3. Check the security provisions of the file and change them, if
necessary. Hewlett-Packard recommends that only MANAGER.SYS has
write access to BOOTPTAB.NET.SYS, and write and purge access to
/etc/bootptab.
Editing the bootpd Configuration File
Use the following steps to edit the bootpd configuration file:
1. Open the file with an MPE text editor. You may edit the
/etc/bootptab file from the POSIX shell or the BOOTPTAB.NET.SYS
file from MPE/iX, whichever you prefer. Both file names should point
to the same file.
2. Add, delete, or change any of the entries in the file. The following
sections give you more information about the contents of the bootpd
configuration file.
3. Save the file and exit the editor program.
