System is complex, requires integration of many other applications, for example: WWW server, mail transfer agent, FTP server, database. Also it should be possible to integrate system with other applications that are specific to companys environment.
Aside integration of existing application platform must be built that will allow to manage everything is a manner undependent from tools that are used in background. It should be a centralized and consistent environment. Also API for developers shoule be generic that changes in tools doesnt require changes in code.
Incredible Hosting System will be based on following tools, technologies:
- Apache as WWW server;
- PostgreSQL as default database;
- ProFTPD as default database;
- qmail or Virtual Qmail as a MTA;
- CORBA as a service communication protocol;

Requirements
In order to run or build the Shezhu Resource Sharing System you need some third-party software available on your machine.
Client
The client needs a modern web browser and the best browsers for this application are Firefox, Mozilla (including the Netscape branded equivalent and Gecko derivatives such as Galeon) and Microsoft Internet Explorer. The newest versions of all these browsers will work best. This application also works with the Konqueror and Opera browsers but these have some issues which may affect functionality. All browsers need JavaScript enabled. Any of these browsers may not work properly (or at all) depending on the operating system they are running under. Text based browsers (such as Lynx) are not supported.
For a comprehensive list of supported client browsers and operating systems refer to this browser compatibility chart from the most recent release of the application.
Server
The server needs recent versions of the Apache web server and the MySQL database server.
The server has only been tested on Redhat9 and FedoraCore3 Linux/i386 platforms although there is no specific reason why it should not work on other Linux platforms and distributions.
Development
Rebuilding this application from source requires a standard Unix development environment with the sh, make, cc, cpp, sed and awk utilities. Also required are RCS, Perl (5.6+) and the ImageMagick program. Also required is RPM to build a distribution. All these programs would probably come as standard in Linux distributions, other platforms may not have all of them by default.
Enhancements:
- This release adds support for Apache2 and multi-site installations, internal restructuring, a better installation tree, and improved access control management.
