HP Insight Control for Linux 6.0 Installation Guide

NOTE: See Chapter 4 (page 29) for more information about configuring DHCP for use with
Insight Control for Linux.
Table 5-2 DHCP server configuration questions
DescriptionItem
The subnet identifier to use in the DHCP configuration. For example, if you
have a class-C network, identified as 192.0.2.0/24, enter 192.0.2.0.
IP network to assign DHCP addresses
The netmask used to identify the network and host components of an IP
address. For example, if you have a standard class-C network, enter
255.255.255.0.
IP network netmask to assign DHCP
address
The first IP address in the range of addresses to be assigned to your
managed systems. For example in the 192.0.2.0/24 network, if you want
addresses to start at 10, enter 192.0.2.10.
Starting IP address in the DHCP range
The last IP address in the range of addresses to be assigned to your managed
systems. If you want addresses to stop after 240, enter 192.0.2.240.
Ending IP address in the DHCP range
An optional parameter that defines a default IP gateway for your managed
systems to use.
If your managed systems have multiple interfaces, with one interface
dedicated to management use, leave this field blank.
Default gateway IP address for DHCP
clients
This is an optional parameter to set the default DNS domain name for your
managed systems.
DNS domain for DHCP clients
This is an optional parameter that instructs the managed systems to use
specified IP addresses for domain name lookups.
DNS server IP addresses for DHCP
clients
Long lease times are very important to Insight Control for Linux. See
Table 4-1 (page 32) for more information.
The default value is 1209600 seconds (two weeks).
Default lease time (in seconds)
The maximum lease time is the longest time that a DHCP client considers
an IP address lease as valid. If a client has not been able to update its address
lease in that time frame, it will stop using it.
The default value is 1814400 (three weeks).
Maximum lease time (in seconds)
You have the option to defer starting the DHCP service. By default, the
installation script starts the DHCP daemon after it has been configured.
If you want to make additional DHCP configuration settings manually, do
not start the service now.

5.3 Validating RPM signatures (optional)
For security reasons, you might want to verify that the RPMs in the Insight Control for Linux
ISO image are properly signed by HP before installing them.
The RPMs for HP Insight Control for Linux are digitally signed with a private key. You have the
option to use the public key shipped on the Insight Control for Linux ISO image to validate and
verify the RPMs. Because you have downloaded the ISO from the Software download site, and
this site is SSL secured by HP, you can ultimately trust that the public key on the ISO is indeed
from HP.
Although this verification process is optional for you, it ensures that HP is the creator of the code
and that the code has not been modified since it was signed.
Determining which public keys are installed
To determine which public keys are installed, enter the following command:
