Solaris DHCP Administration Guide

Writing a Script That Uses dhtadm to Create Options and Macros

You can create a Korn shell script by adapting the example in Example 4–1 to create all the options listed in Table 4–11 and some useful macros. Be sure to change all IP addresses and values contained in quotes to the correct IP addresses, server names, and paths for your network. You should also edit the Vendor= key to indicate the class of clients you have. Use the information reported by add_install_client -d to obtain the data needed to adapt the script.

Example 4–1 Sample Script to Support Network Installation

# Load the Solaris vendor specific options. We'll start out supporting 
# the Ultra-1, Ultra-30, and i86 platforms. Changing -A to -M would replace
# the current values, rather than add them.
dhtadm -A -s SrootOpt -d 'Vendor=SUNW.Ultra-1 SUNW.Ultra-30 SUNW.i86pc,1,ASCII,1,0'

As superuser, execute dhtadm in batch mode and specify the name of the script to add the options and macros to your dhcptab. For example, if your script is named netinstalloptions, type the command:

dhtadm -B netinstalloptions

When you have done this, clients that have vendor client classes that are listed in the Vendor= string can use DHCP to obtain the parameters they need for Solaris installation over the network.
