HP Insight Control for Linux 6.0 Installation Guide

A Alternative network configurations
This appendix provides optional, alternative network configurations that are supported for use
with Insight Control for Linux in addition to the network configurations described in Chapter 4
(page 29). The following topics are addressed:
• “Integrating Insight Control for Linux with an external DNSMASQ DHCP server” (page 73)
• “Integrating Insight Control for Linux with an external Microsoft DHCP configuration”
(page 73)
• “Configuring a static IP Address using DNSMASQ” (page 81)
• “Configuring a static IP address using ISC DHCP” (page 82)
• “Configuring a multiple subnetwork topology” (page 82)
A.1 Integrating Insight Control for Linux with an external DNSMASQ DHCP
server
DNSMASQ is a popular lightweight DHCP and DNS server, which you can integrate for use
with HP Insight Control for Linux. Similar to the ISC DHCP server, DNSMASQ is configured in
a text file, similar to the sample shown in Example A-1. This file is usually located in the /etc/
dnsmasq.conf file on the server providing your DHCP service.
Example A-1 Sample DNSMASQ configuration file
# Configuration file for dnsmasq
# replace the following with the proper interface name for service DHCP
interface=eth0
domain-needed
bogus-priv
filterwin2k
domain=wlab.hp.com
expand-hosts
dhcp-lease-max=20000
# pXe Boot Configuration
dhcp-boot=/pxelinux.bin,boothost,172.1.1.1
# System Imager DHCP Option--IP Address of the CMS
dhcp-option=140,"172.1.1.1"
# Turn on logging
log-queries
dhcp-range=172.1.1.100,172.1.1.200,255.255.255.0,24h
A.2 Integrating Insight Control for Linux with an external Microsoft DHCP
configuration
The Microsoft DHCP server provides a graphical management utility for configuring the DHCP
service options. Integrating HP Insight Control for Linux with a Microsoft DHCP configuration
is easy to do because the utility natively supports the setting of the boot server and boot file name
used by PXE to network boot servers.
However, the utility does not have a built-in option for setting the System Imager Option 140
required by Insight Control for Linux. Therefore, follow this procedure to add the System Imager
option before you configure the Scope Options.
