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.

Web Sharing is a small tray applet for sharing files on the web.

Publish anything on the Internet or your local area network at home, office or school from a folder on your hard disk with just a few clicks of a mouse!

Main features:
- JavaBlowfish encryption
- SHA-384 of passwords

Volume Sharing Manager (Vsman) is a utility that has been designed for volume (directory) sharing management on the server side. So far, it manages NFS v3 and V4, but can be extended to others volume sharing systems.
You can select a NFS v4 server interface in the preferences dialog box. Otherwise, invoke vsman with the flag -4 in order to display the NFS v4 specific mounting options when needed.
Vsman must be run as root. It displays on the left a tree view of known directories with their possible accesses, i.e. client hosts that can mount directories from the server where vsman is running.
Each directory is displayed with a green, yellow or red spot.
Green if the directory is exported but not mounted.
Yellow when exported and mounted.
Red when unexported.
When you double-click on an access, the left side shows its mounting options.
You can obviously declare a new volume. Vsman just asks you the name of the corresponding directory. You can of course create or delete accesses for the current volume. When you create one, a dialog box appears, that asks you the suitable host name, network
name or address, or netgroup name.
If the host filed is empty, the networks field is then tested, and if empty again, the netgroup is selected.
If you select "NIS" instead of "Files" in the preferences dialog box, the hosts, networks, users and groups will be fetched from the given NIS domain name. For more info about NIS, read the corresponding HOWTO documentation.
Selecting the Reexport menu will reexport all and synchronize vsman with the exported volumes declared in /etc/exports.
Double-click on a mounting host and select Unexport Host in the Action menu, and the current volume will be unexported from the corresponding volume.
Unexport whole volume will do the same thing, but for all the mounting hosts.
The Start / Stop menu will stop or restart the NFS server.
The Save menu will write the NFS /etc/exports file and reexport all volumes.
This tool has been written in Ada 95, using gtkada 2.4 as the toolkit. Dont forget to install gnat 4.1.x or later. Gnat is now a component of the gcc suite.
Enhancements:
- A few important bugs were fixed.
- Hostname lookup was added.
- The compilation and installation process was improved.

Sender Rewriting Scheme Library is an ANSI C implementation of the Sender Rewriting Scheme.

It solves the "broken forwarding" problem imposed by SPF (Sender Policy Framework), which is an SMTP Anti-Forgery technology currently under development and deployment worldwide.

And dont think ive done it right either. If its simple and you feel like it submit a patch, otherwise just be as verbose as you can in describing your errors. Please submit output using the -DDEBUG and -DVDEBUG compile time options as these are of the greatest help.

Real-Time Proactive Secret Sharing Library is an implementation of the Shamirs secret sharing scheme and Herzbergs proactive secret sharing algorithm.

Real-Time Proactive Secret Sharing Library targets the RTAI OS. It includes a port of GNU GMP to RTAI, which is used for multiple precision arithmetic operations.

to run the rt-pss

./start_pss ID (*) ID should be between 0 and PSSW_NUMBER_OF_MACHINES-1(this constant is defined in src/share_app_pssw.h)
(*) each local RT-PSS should be executed with a
different ID starting with 0
(*) you must have superuser privilegies to do that.

to stop the rt-pss


./stop_pss (*) be sure that no applications that uses the RT-PSS are
running.
(*) you must have superuser privilegies to do that.

developing RT-PSS Apps

There is a demo application available in the directory: examples/GetShare. The RT-PSS API can be consulted in the file README.API

Inlab-Scheme is an independent implementation of the algorithmic language Scheme and conforms to the R4RS and the IEEE Standard 1178.
In addition to the language core, Inlab-Scheme has support for image processing which allows the implementation of OCR and image recognition applications.
Inlab-Scheme project comes with two built in graphic file format converters which convert the PATIMG patent file format and the ST.33 patent file format to multipage TIFF without decompressing.
Main features:
- Inlab-Scheme is an independent implementation of the algorithmic language Scheme and conforms to the R4RS and the IEEE Standard 1178.
- Inlab-Scheme 4 passes the r4rstest.scm test incuding the tests for continuations, Scheme 4 and delay/force.
- Pretty printing, fluid-let, dynamic-wind and syntax procedures using Inlab-Scheme syntax-lambda.
- Bitmaps: Reading and writing TIFF (G4, single/multipage), XBM and PNG file formats, scaling, rotating, comparing, inverting, cropping, page decomposition (exploding), line drawing, greymap conversions and more.
- Greymaps: 256 greylevel images, reading and writing PNG file formats (reads anything, writes PNG greylevel interlaced/not interlaced), scaling, cropping, conversions to and from bitmaps for further analysis and processing and more.
- Inlab-Scheme Release 4 comes with two built in graphic file format converters which convert the PATIMG patent file format (as found on the USAPat CDROM series of the US PTO) and the ST.33 patent file format (as found on the US PTO PATENTIMAGES CDROM series and the european ESPACE CDROM series) to multipage tiff without decompressing.
- Inlab-Scheme Release 4 comes as a single binary to reduce installation to an absolute minimum.
- Its easy to write Inlab-Scheme scripts that may be invoked directly from your shell using the #!-mechanism.
Enhancements:
- The license was changed to the GPL.
- A code cleanup addressing licensing issues has been performed.
