Use this installation method if you want to install keys and set client configuration information at the command line during the installation.
This procedure assumes that you are using HTTPS in your WAN installation. If you are performing an insecure installation that does not use keys, do not display or install the client keys.
Assume the same user role as the web server user on the WAN boot server.
Display the key value for each client key.
# wanbootutil keygen -d -c -o net=net-ip,cid=client-ID,type=key-type
The IP address of the subnet for the client you want to install.
The ID of the client you want to install. The client ID can be a user-defined ID or the DHCP client ID.
The key type you want to install on the client. Valid key types are 3des, aes, or sha1.
The hexadecimal value for the key is displayed.
Repeat the previous step for each type of client key you are installing.
If the client system is currently running, bring the client to run level 0.
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,bootserver=wanbootCGI-URL
The line breaks in this command sample are included for formatting purposes only. Do not enter a carriage return until you finish typing the command.
Instructs the OBP to set the following boot arguments
Specifies the IP address of the client
Specifies the IP address of the network router
Specifies the subnet mask value
Specifies the host name of the client
Specifies the IP address and port of the network's proxy server
Specifies the URL of the wanboot-cgi program on the web server
At the client ok prompt, boot the system.
ok boot net -o prompt - install
Instructs the client to boot and install from the network. The wanboot program prompts the user to enter client configuration information at the boot> prompt.
The boot> prompt is displayed.
Specifies the hexadecimal string of the 3DES key that is displayed in Step 2.
If you use an AES encryption key, use the following format for this command.
Install the hashing key.
Specifies the hashing key value that is displayed in Step 2.
Type the following command to continue the boot process.
The client installs over the WAN.
If prompted, type client configuration information on the command line.
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.
In the following example, the wanboot program prompts you to set the key values for the client system during the installation.
Display the key values on the WAN boot server.
# wanbootutil keygen -d -c -o net=192.168.198.0,cid=010003BA152A42,type=sha1 b482aaab82cb8d5631e16d51478c90079cc1d463 # wanbootutil keygen -d -c -o net=192.168.198.0,cid=010003BA152A42,type=3des 9ebc7a57f240e97c9b9401e9d3ae9b292943d3c143d07f04
The previous example uses the following information.
Specifies the IP address of the client's subnet
Specifies the client's ID
Specifies the value of the client's HMAC SHA1 hashing key
Specifies the value of the client's 3DES encryption key
If you use an AES encryption key in your installation, change type=3des to type=aes to display the encryption key value.
Set the network boot argument variables in the OBP 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=seahag, bootserver=http://192.168.198.135/cgi-bin/wanboot-cgi
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.
Boot and install the client.

The previous commands perform the following tasks.
Installs the 3DES encryption key with the value 9ebc7a57f240e97c9b9401e9d3ae9b292943d3c143d07f04 on the client
Installs the HMAC SHA1 hashing key with the value b482aaab82cb8d5631e16d51478c90079cc1d463 on the client
