To Perform a Noninteractive WAN Boot Installation

Use this installation method if you prefer to install keys and set client configuration information before you install the client. You can then boot the client from the WAN and perform an unattended installation.

This procedure assumes that you have either installed keys in the client's OBP, or that you are performing an insecure installation. For information about installing keys on the client before your installation, see Installing Keys on the Client.

1. If the client system is currently running, bring the system to run level 0.

   # init 0

   The ok prompt is displayed.

2. At the ok prompt on the client system, set the network boot argument variables in OBP.

   ok setenv network-boot-arguments host-ip=client-IP, router-ip=router-ip,subnet-mask=mask-value, hostname=client-name,http-proxy=proxy-ip:port, file=wanbootCGI-URL

   ---

   setenv network-boot-arguments

   Instructs the OBP to set the following boot arguments

   host-ip=client-IP

   Specifies the IP address of the client

   router-ip=router-ip

   Specifies the IP address of the network router

   subnet-mask=mask-value

   Specifies the subnet mask value

   hostname=client-name

   Specifies the host name of the client

   (Optional) http-proxy=proxy-ip:port

   Specifies the IP address and port of the network's proxy server

   file=wanbootCGI-URL

   Specifies the URL of the wanboot-cgi program on the web server

3. Boot the client.

   ok boot net - install

   net - install

   Instructs the client to use the network boot argument variables to boot from the WAN

   The client installs over the WAN. If the WAN boot programs do not find all the necessary installation information, the wanboot program prompts to provide the missing information. Type the additional information at the prompt.

Example 13–4 Noninteractive WAN Boot Installation

In the following example, the network boot argument variables for the client system myclient are set before the machine is booted. This example assumes that a hashing key and encryption key are already installed on the client. For information about installing keys before you boot from the WAN, see Installing Keys on the Client.

ok setenv network-boot-arguments host-ip=192.168.198.136,
router-ip=192.168.198.129,subnet-mask=255.255.255.192
hostname=myclient,file=http://192.168.198.135/cgi-bin/wanboot-cgi
ok boot net - install

The following variables are set.

• The client IP address is set to 192.168.198.136.

• The client's router IP address is set to 192.168.198.129.

• The client's subnet mask is set to 255.255.255.192.

• The client's host name is set to seahag.

• The wanboot-cgi program is located at http://192.168.198.135/cgi-bin/wanboot-cgi.
