This feature is new in the Software Express pilot program and in the Solaris 9 12/03 release. This feature is included in the Solaris 10 3/05 release.
The Solaris software now enables you to boot and install software over a wide area network (WAN) by using HTTP. The WAN boot installation method enables you to install the Solaris release on systems over a large public network where the network infrastructure might be untrustworthy. You can use WAN boot with new security features to protect data confidentiality and installation image integrity.
The WAN boot installation method enables you to transmit an encrypted Solaris Flash archive over a public network to a remote client. The WAN boot programs then install the client system by performing a custom JumpStart installation. To protect the integrity of the installation, you can use private keys to authenticate and encrypt data. You can also transmit your installation data and files over a secure HTTP connection by configuring your systems to use digital certificates.
