Configuring for a DHCP Server
Setting Up a DHCP Server
In this case, you will need to add the variable definition to a specific
interface variable block. As an example, you would need to add
DHCP_ENABLE[2]=1 to the following interface variable block in order
to enable DHCP on the lan1 interface:
INTERFACE_NAME[2]=lan1
IP_ADDRESS[2]=15.1.50.89
SUBNET_MASK[2]=255.255.248.0
BROADCAST_ADDRESS[2]=""
The contents of /etc/rc.config.d/netconf for this definition
block should now look like the following:
INTERFACE_NAME[2]=lan1
IP_ADDRESS[2]=15.1.50.89
SUBNET_MASK[2]=255.255.248.0
BROADCAST_ADDRESS[2]=""
DHCP_ENABLE[2]=1
Correspondingly, you could disable DHCP over a particular interface
by setting the variable to "0".
Again, as in the first method, the system will only begin using DHCP
after the next reboot.
Examples of DHCP Usage
To enable a DHCP server to respond only to specific clients, use the
instl_adm(1M) tool to configure specific dhcp_class_id's.
DHCP Examples For example, your situation might fall into one of the following four
categories:
1. The network has a DHCP server that manages the whole network,
and the clients doing installations will be using the addresses from
this server permanently. Then the Ignite-UX server setup should be:
• Don't set up DHCP on Ignite-UX server In this case, enter the
following in INSTALLFS, (using instl_adm).:
is_network_info_temporary=false
2. The network has a DHCP server, but the user would like to manage a
small group of temporary IP addresses, just for use in doing
installations, and the clients will get reassigned new addresses when
deployed.
