The web server software you use on your WAN boot server and install server must meet the following requirements.
Operating system requirements – WAN boot provides a Common Gateway Interface (CGI) program (wanboot-cgi) that converts data and files into a specific format that the client machine expects. To perform a WAN boot installation with these scripts, the web server software must run on the Solaris 9 12/03 OS, or compatible version.
File size limitations – Your web server software might limit the size of the files you can transmit over HTTP. Check your web server documentation to make sure the software can transmit files that are the size of a Solaris Flash archive.
The flarcreate command no longer has size limitations on individual files. You can create a Solaris Flash archive that contains individual files over 4 Gbytes.
For more information, see Creating an Archive That Contains Large Files in Solaris 10 10/09 Installation Guide: Solaris Flash Archives (Creation and Installation).
SSL support – If you want to use HTTPS in your WAN boot installation, the web server software must support SSL version 3.
