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.

KDE Internet share wizard is a Kommander script that can help you share your internet connection over LAN.
Overview:
I was on a LAN and I needed to share my internet connection because we didnt have any router.
I found this to be quite difficult, but after some searching on internet I found a very good explanation for making this work.
Now, Ive made a WindowsXP like internet connection sharing guide for all who wants to share their internet connection easy and fast.
Usage:
copy the tar.gz file contents into /usr/bin and then run:
kdeinternetshare.sh - English
For all those who are unsure how to use the guide, it should be good to stick to the default settings.
This is only a quite simple guide so suggestions and improvments are welcome.
System requirements:
- Kommander

Hybrid Share is a User Friendly Application for Linux, Mac and Windows users, that allow you to Share file (and Talk) instantly with your friends...

What is Hybrid Share ?

Hybrid Share is a simple (User Friendly) Mono C#/Gtk# Application that allow Mac, Windows and Linux Users To Share Files. The Application is extensible via Plugins, so you can Talk with connected people, check your mailbox or other things that plugins could do.

What do you use if you have to share files with your friends ?

E-Mail or Instant Messaging are the first possible solution, but the E-Mail Size block and the slowing of the IM make this channels bad to share files. The NFS (Network File System) or other system like this, works only between similar system or are a little bit difficoult to configure, the same for ftp server.

So The Solution is Hybrid Share that is Portable and Easy to Use, It isnt the Best Application in The World, but it does a useful work.

What is the Difference with a Normal P2P ?

Hybrid Share has a core of P2P but is more like a traditional IM (Instant Messenger), like GTalk, MSN, Gaim, Adium and so on.... No Network Configuration is needed, Youve only to add your "buddies" (like an IM) and Drag File Into their folders...
