Free platform independent solution software for linux

iFTPd, Independent FTP Daemon, is an open source FTP server written in Java. Independent FTP Daemon features platform independence, system independence, ruggedness and a virtual file system.
The target audience of the FTP server is for those admins that need to be able to share files without having to install several other programs and databases and without having to configure the rest of the system.
Main features:
- Platform independence (Where do you want your JVM to go today?)
- System independence
- Does not require any users / groups on the host system.
- Does not require an SQL database.
- Does not does have weird and wonderful dependencies that must be downloaded from 500 different places.
- Ruggedness
- Once started, only the admin can stop iFTPd
- Virtual file system
- Create virtual file links, virtual directory links
- Merge several directories into one virtual directory
- Completely transparent to the user
- Users and groups
- Firewall friendly
- Multithreading
- Text file-based configuration
- Telnet-based status monitor
- HTML status monitor
Installation:
Unpack iftpd.zip.
Check that conf/iftpd.conf is to your liking.
Make at least one group in conf/groups/.
Make sure that at least one of the groups has a root directory.
"/stash/ftp/" r+ "/"
Make at least one user file in conf/users/.
Start iFTPd.
Linux users run: iftpd.sh
Enhancements:
- SSL (AUTH TLS) support has been added.
- Old scripts have been replaced with iftpd.sh.
- ALLO has been added for binary mode, but untested because no clients support it.
- Groups can contain other groups.
- SITE UTIME support has been added.
- Group files can have empty lines.
- CLNT support has been added.
- StatusToHtml (#CLIENTNAME#) has been added.
- The rename bug has been fixed (only worked with full paths before).
- Aborted transfer notification should finally be fixed.
- FEAT support has been added.
- IdleStrictChecking has been added in iftpd and iftpd.conf.

FileSystem Investigator is a platform independent file system viewer and data extraction tool. It allows the user to:

* View the contents of the target file system in a forensicly safe manner, bypassing the normal operating system mechanisms.
* Extract files and whole directory trees of files from the source filesystem.

Since it is written in platform-neutral Java, it can be used to examine filesystems outside their native environment. For example, it can be used to view a Linux filesystem while running under Windows.

FileSystem Investigator directly accesses the source disk and processes the data using it own built in filesystem drivers. This ensures that it is safe to use FileSystem Investigator for forensic investigations.

FileSystem Investigator will never write to the source media thus important timestamps are preserved. FileSystem Investigator can also read disk-image files such as those created by dd.

Files and whole directory structures can be extracted easily from the source drive and stored for further use or analysis. Due to limitations imposed by Java, special files such as device nodes, pipes, sockets and links, cannot be extracted.

Brutus is an Open Source connector for Exchange 5.5, 2000 and 2003, to put it short. Our aim is to scratch one of the most annoying itches that the Open Source community have endured. This particular itch has been experienced for almost a decade.
The problem that we are addressing is the problem of platform independent access for client applications to Microsoft Exchange from version 5.5 onwards.
Our solution to this problem will enable a feature-by-feature compatible Microsoft Outlook replacement for Linux, Microsoft Windows, the BSDs or almost any other platform.
How do we do it?
We have developed a CORBA based framework on top of the Messaging Application Programming Interface commonly known as MAPI.
Our development framework is offering client applications MAPI based access to any MS Exchange server from version 5.5 onwards. We believe that we are providing the Open Source community with a development framework that are superior to any other approach.
Our solution is distributed under the GNU General Public License (commonly known as the "GPL") or a commercial license.
Why do we do it?
We feel that there is a strong customer need for a non-Microsoft client application with full Exchange integration that is feature-by-feature comparable with Microsoft Outlook.
The only technically feasible way to achieve this level of integration is to build a client access framework on top of MAPI.
Out strategy is therefore to provide this framework to the Open Source community free of charge under the GPL and to the any commercial entity under a commercial license.
Enhancements:
- Support for OpenSUSE 10.2 was added.
- brutus-keyring is now used instead of gnome-keyring.
- A thread storm when updating the folder summary is now avoided.

OpenInput project is a cross-platform, easy-to-use, portable input handler library, written in C.
The primary goal of OpenInput is to make it easier for application programmers to write portable code that deals with input from mice, keyboards, joysticks and other devices.
In other words, OpenInput will allow you to write a single piece of code that handles input for your application for all platforms, for example GNU/Linux, Windows and MacOS X.
This is achieved by abstracting the low-level platform-specific input device handling into a stable, intuitive, platform-independent API: OpenInput.
Main features:
- Total platform independence
- Easy to use, sane and simple API
- Fully documented functions and data structures
- Automatic configuration of available devices
- Generic event handling
- Keyboard state managment (eg. up/down/lock)
- Mouse motion and state managment (eg. movement, buttons up/down)
- Joystick motion and state handling for axes, hats and trackballs
- Can "hook" into existing windows
- Provides resize, iconify, close and expose events for the application window
- Action mapping, so events can be handled without any knowledge of the underlying device
- Pointer (mouse) grabbing inside window
- Show/hide pointer inside window
- Keyboard focus grabbing
Enhancements:
- This version contains major documentation updates, both big and small bugfixes, and minor feature enhancements which dont break the API.
