Solaris 10 10/09 Installation Guide: Network-Based Installations

Create the Keys for the Server and the Client

To protect the data transmitted between the server and client, you create a hashing key and an encryption key. The server uses the hashing key to protect the integrity of the wanboot program. The server uses the encryption key to encrypt the configuration and installation data. The client uses the hashing key to check the integrity of the downloaded wanboot program. The client uses the encryption key to decrypt the data during the installation.

First, you assume the same user role as the web server user. In this example, the web server user role is nobody.

wanserver-1# su nobody

Then, you use the wanbootutil keygen command to create a master HMAC SHA1 key for wanserver-1.

wanserver-1# wanbootutil keygen -m

Then, create a hashing key and an encryption key for wanclient-1.

wanserver-1# wanbootutil keygen -c -o net=,cid=010003BA152A42,type=sha1
wanserver-1# wanbootutil keygen -c -o net=,cid=010003BA152A42,type=3des

The previous command creates a HMAC SHA1 hashing key and a 3DES encryption key for wanclient-1. specifies the subnet of wanclient-1, and 010003BA152A42 specifies the client ID of wanclient-1.
