Free admin tools software for linux

Kiosk Admin Tool is a Point&Click tool for system administrators to enable KDEs KIOSK features or otherwise preconfigure KDE for groups of users.
Enhancements:
- Fixed lookup of UNIX-groups in kiosktool-kdedirs
- Removed "Lock down system wide Desktop icons", it was not implemented
- Removed duplicate "Disable Menu Editing" entry

Admin is entirely written in Java. It uses Swing GUI Components and JDBC to connect to databases. It has been succesfully tested with MySQL, InstantDB, Oracle, Empress, and PostgreSQL.

You can have a tree view of the RDBMS or pick a single instance to have a look at its metadata. It allows you to create, modify, and drop tables and to create indices on a table. The dynamic form makes it easy to enter data into a certain table, and the guided query makes it easy to retrieve data from a table and to export it.

Java developers will probably enjoy the code generator doing an OO relational wrapper and a swing GUI for them. You can also export and import data and transport it from one DBMS to another.

Slax Tools project are graphical applications that simplify process of generating custom version of live distribution Slax.
Slax Konfigurator is QT application that guides user through downloading Slax ISO image, management of modules, management of custom documents and bootloader configuration. Modified ISO can be installed on USB pen drive or recorded on CD. Slax Konfigurator requires QT, kdesu, sudo, cdrecord or wodim
Slax Module Kreator converts RPM (Red Hat, Fedora, Mandriva), DEB (Debian, Ubuntu), TAR.GZ (Arch Linux) and TGZ (Slackware, KateOS) binary packages into Slax modules. Slax Module Kreator depends on KDE 3.5, mksquashfs and rpm2cpio (RPM only), dpkg (DEB only) and tar (TAR.GZ and TGZ only).
Enhancements:
- Slax Konfigurator - now you can test generated ISO image in QEmu before burning (obviously, QEmu is required for that)
- Slax Module Kreator - it is possible to output modules into selected shared directory instead of creating them in source directory
- various bug fixes

The Linux Wireless Extension and the Wireless Tools are an Open Source project sponsored by Hewlett Packard (through my contribution) since 1996, and build with the contribution of many Linux users all over the world.

The Wireless Extension (WE) is a generic API allowing a driver to expose to the user space configuration and statistics specific to common Wireless LANs. The beauty of it is that a single set of tool can support all the variations of Wireless LANs, regardless of their type (as long as the driver support Wireless Extension).

Another advantage is these parameters may be changed on the fly without restarting the driver (or Linux).

The Wireless Tools (WT) is a set of tools allowing to manipulate the Wireless Extensions. They use a textual interface and are rather crude, but aim to support the full Wireless Extension. There are many other tools you can use with Wireless Extensions, however Wireless Tools is the reference implementation.

iwconfig manipulate the basic wireless parameters
iwlist allow to initiate scanning and list frequencies, bit-rates, encryption keys...
iwspy allow to get per node link quality
iwpriv allow to manipulate the Wireless Extensions specific to a driver (private)
ifrename allow to name interfaces based on various static criteria

Most Linux distributions also have integrated Wireless Extensions support in their networking initialisation scripts, for easier boot-time configuration of wireless interfaces. They also include Wireless Tools as part of their standard packages.
Wireless configuration can also be done using the Hotplug scripts and distribution specific support, this enable the proper support of any removable wireless interface (Pcmcia, CardBus, USB...).

Any versions of the Pcmcia package offer the possibility to do wireless configuration of Pcmcia and Cardbus card through thefile wireless.opts. This allow to fully integrate wireless settings in the Pcmcia scheme mechansism. However, this method is now deprecated in favor of distribution specific methods.

Please note that the Wireless Tools (starting with version 19) supports fully IEEE 802.11 parameters and devices, support older style of devices and most proprietary protocols, and are prepared to handle HiperLan as well. More recent versions of course adds more 802.11 support.

But, unfortunately not all drivers support all these features...

MIME-tool is a little mime encoding tool I slapped together when I needed something on a production box at work (productions = no C development environment, only the ancient K&R compiler required for god-knows-what sys-admin task).
The resulting program will compile happilly on both the crippled C compilers bundled with some commercial *nix distributions, and on full ANSI/ISO C compilers like gcc.
I wrote this program when I needed a tool to construct MIME encoded emails with file attachments in job scripts on a production box. Being a production box it didnt have any development tools installed. However, the box DID have a K&R C compiler that appears to be necessary for some administrative task or another (configuring the kernel?). If you tried to compile even fairly simple ANSI/ISO C source the compiler bitched and moaned about all the stuff it didnt support, which will stop most folk (at least those who dont know anything about the history of the C programming language) from building their own binaries.
Since Im old enough to actually have written C code back before we had the ANSI/ISO standard and all the accompanying niceties, I was not stymied by a the lack of ANSI/ISO support. Its really not all that hard to write K&R compliant code, so long as you dont need the compiler to check your function calls for you. For a program this small, however, thats not much of a concern.
Since the program is meant to be compiled on systems with minimal support (there is no telling what unrestrained IT staff will decide must be removed in the interest of system security) I didnt bother to include a makefile. On every system I have tried, however, the program compiled with the simple incantation
cc -o mime mime.c
but your selected target system may require extra special magics.
The program supports the basic MIME standard: The caller can select the content type (application/octet-stream, text/plain, or user specified), content type encoding (7bit, 8bit, binary, base64 or auto-detected) and the boundry string (defaults to "=_MIME_CONTENT_BREAK_="). Further, the caller may specify the e-mail subject, to address, from address, carbon copy address and text for a prolog and epilog. The content type and encoding may be specified separately for each attached file.
The programs calling format is:
mime [-dDvV] [-S subject] [-F from-address] [-T to-address]
[-C carbon-copy address] [-P prolog-text] [-E epiplogue-text]
[-B boundry] {[-78abqux] [-t content-type] filename}
-d low detail debugging
-D high detail debugging
-v verbose messages
-V very verbose messages
-7 7-bit ASCII encoding
-8 8-bit ASCII encoding
-a application/octet-stream content type
-b binary encoding
-q quoted-printable encoding
-t text/plain content type
-u unknown encoding, auto-detect
-x base64 encoding
Theres really not much to this program. Once you know how the MIME messages are constructed you could do most of it manually (except for the base64 encoding, which would require a program like this), but if there are any problems with it, I would like to know about them.
Enhancements:
- A typo in the online help message was fixed.
- A known bugs section was added to the manpage.
- Proper quoting and folding were added to the filename header.

NG-Admin is designed for the content management of Databases, i.e. to browse, add, edit and delete data. It is somewhat similar to phpMyAdmin, but it is specialized to edit contents of the websites, not to edit the database structure. NG-Admin features are very easy to use and highly tunable.
NG-Admin was initially based on DASystem by Degtyarev Dmitriy, but because this project is no longer updated (last from 2003-11-28), we wrote lots of code completely new and added new functions and modules.
Main features:
- Easy to use, do not require training or special knowledge
- Easy to tune, just edit a single configuration file
- Multilingual support (English and German at the moment)
- Theme support (currently blue, red and a silver theme)
- Easy accessible menu always on the screen
- Automatical generation of menus and forms
- Supports MySQL
- Supports Browser upload of images and files
- Uploads can be made to local Directory or to a FTP-Server
- Cross-table data access
- Support for external modules
Enhancements:
- A new field named "timestamp_manual" has been added.
- As it says, it is to set values of timestamp fields manually.
- The error-messages are more detailed.
- By clicking "details" in the message box (available only on error), you will see a more detailed description about the error and why it occurred.
- The configuration file is easier to understand and has better comments sections.
- Minor fixes and speed improvements were made with colors and delete.
- A bug with local upload was fixed.

CryptoMX Tools is a set of encryption, steganography, cipher, hashing and conversion tools designed to work on any operating system with any Javascript-capable browser.
Enhancements:
- Added SHA-256 Algorithm.
- Used COPYING, README, AUTHORS, and ChangeLog Files.
- Removed a bit of useless code.
- Decreased Filesize.
- Misc. Fixes.
