Captive: The first free NTFS read/write filesystem for GNU/Linux

This project is no longer maintained.

Project implements the first full read/write free access to NTFS disk drives.You can mount your Microsoft Windows NT, 200x or XP partition asa transparently accessible volume for your GNU/Linux.

This compatibility was achieved intheWine way by using the originalMicrosoft Windowsntfs.sys driver. It emulates the required subsystems ofthe Microsoft Windows kernel by reusing one of the originalntoskrnl.exe,ReactOS parts, orthis project's own reimplementations, on a case by case basis.Project includes the first open source MS-Windows kernel API for Free operating systems.Involvement of the original driver files was chosen to achieve the bestand unprecedented filesystem compatibility and safety.

As opposed to other projects this is currently the only software supporting the fullread/write access including the possibility to create/delete files, modify directoriesetc.

PerlMail: Perl mail processor - procmail(1) successor

Successor toprocmail(1)andMail::Audit.It supportsPerl-rules filtering, dynamic client IP,mobile SMS forwarding,Mutt integration,Nokia Communicator contacts directory integration.

mdsms: Mobile Device SMS Tool

Program sends NOL or NGG files as Nokia operator logo or group graphics throughNokiaCommunicator9110 (9000/9000iis not compatible). Usually you needto have either infra-red port in your computer or special FBUS cable to be ableto use conventional logo-uploading tools (such asgnokii).This program uses only standard modem cable and the integratedFaxModem capability of 9110.

tcp_rto: Linux kernel maximal TCP round-trip-time patch

Solve your problems with network connection dropping too much of yourpackets. It forces Linux kernel to insist repeating the packages to preventslowdown of the TCP connection up to its unusable state.

wayback: Shift system time backwards for a specific application

This programs is userful for time-limited demo versions, of course.

Just set environment variable "WAYBACK" to the number of seconds to shift the system time back.Set "LD_PRELOAD" to the providedlibwayback.so and run your demo program.

tac_plus auth: Cisco TACACS+ NAS host based authorization

Patch provides complete freedom of specifying anyconfiguration changes depending on the specific NAS the user is being loggedon. This involves different enable password, NAS keys but now also: variousspecific commands, permitted services etc.

Server used on GNU/Linux as a replacement for proprietaryKaliNix network game server.

timeplan: Calculate statistics from your personal time tracking notes

Software to do summaries of time log - what have you spent much time on.The greatest effect to me was just the writing of such time log: Consecutivelyyou do not spend such time on useless issues as you would be forced to writesuch event to your log.

ssht: Unattended intranet host accessibility by SSH tunnel

Do you need to admin remote host placed in the intranet behind firewall out of your control?If the firewall performat NAT (masquerade) where you can connect fromthe intranet to the outer world bySSHyou can use these security safe scripts.

If you are able to set up port forwarding on the firewall you do not need any such scripts.In the case of HTTP-only proxy you cannot use these scripts - look elsewhere.

AutoGen: autogen.sh while supporting CVS/.rpm/.deb

Projects usually have theirautogen.sh script files to runautoconf(1),automake(1) and similiar tools.This project has some additional features:

checkstatic: C sources symbol attributes checker

Scripts gives additional warnings not provided by GNU C Compilersuch as dead code declared asglobal in separate file,missingstatic keywords etc.

It can get very valuable during stripping functionality off ofa big package for embedded resource-limited machines.

cvsutil: Clean CVS checkout working files or safely change CVS/Root

List the specified types of files and safe settings of CVSROOTfor already checkouted package. As an example of its many applicationscan serve a handy prevention of grepping built files:grep -w wanted_sym `cvsfiles`

staticbuild: Fully static binaries build - GNU/Linux vendor independence

There exists too many GNU/Linux distributions - vendors - and any producedbinary is not compatible with all of them due to the shared libraries andconfiguration files dependencies. Due to many hardcoded shared libraries it isno longer possible to just usegcc -static. These patches provide thefunctionality you would expect from:gcc -static

cvsbranchdiff: CVS Branching Utility

During patching of foreign CVS trees you have to regularly import themas CVS does not support multiple repositories. There is a problem withnew or removed files, this simple tool will take care of them.

Using this very simple program you can convert between these two.

wllib: Graphics library for crossplatform line drawing

This library should make you generically use line drawing on the following platforms:UNIX/X Windows System X11 (libX11),UNIX/SVGAlib andAmigaOS.

vblib: High performance memory streams library

Enables application to easily do input/output functions (likeread/write, printf etc.) with memory streams while using performance effectivefunctions. Simple buffer copying/moving would be possible but it would case amajor performance hit if not using algorithms implemented in this library.

PHP Web: PHP web framework

Each web author has his own web framework reusable for other web developersas a generic engine. Here is mine. I am not a fool to expect you would useit.

Specifically thisPHP-based web frameworkis already many years obsolete as I am now using instead myPerl/mod_perl-basedMy::Web web framework. Still this version is being maintained asit is marginally in use.

LaserGame: Firmware and config tool for shooting gun

LaserGame is a clone of commercial shoot'n'run game. Each player has itsown hardware with multiple infra detecting sensor and one laser/infra gun.Shooting is visually targeting by red laser diode while the shootinginformation is being emitted by infrared.

Its Amiga communication tool will receive shooting statistics while beingalso capable of remote hardware configuration.

ResRAM: Reset-persisent bootable RAM filesystem

ResRAM is generally used for the RAM disks which are not required to bewritten to. They are being used for fast booting when no harddisk isavailable. On ResRAM execution it scans the given files which are loaded to thememory and a reset-surviving resident module is installed.

PortDiag: Hardware I/O port diagnostics utility

PortDiag is generally used for low-level hardware watching and modifying.It has support for all the bits of the four CIA ports, digital and analog partsof the game ports, serial port TXD and RXD signals and selective systemallocation of this hardware.

ShortRel: Executable file relocations compressor

ShortRel loads the input file (must be an executable), converts relocations(32-bit to 16-bit or vice versa), strips debug informaion (if requested) andwrites out the result. 16-bit relocations use 2 bytes per each one and 32-bitrelocations use 4 bytes. So conversion of any executable with many relocationsfrom 32-bit to 16-bit relocations saves 2 bytes per each one.

QueryDev: Detect disk device name from its volume name

QueryDev detects the device name from the given volume name. Volume must belocked in the system. Useful for DiskCopy which has the parameter DEVICE andyou want to copy the diskette from any drive. QueryDev writes the detecteddevice name to the specified variable.

SClock: Synchronize the local system clock

SClock reads the current date and time from the remote machine and sets thistime on the local machine. You can save this time to battery backed up clock,if present.

In fact this is the same work as does the standard AmiTCP command SynClock,but SClock has no need for the TCP: device, the inet-handler and is much faster(no REXX).

MS-Windows

TraceFS: Microsoft Windows Kernel API Tracer

Project allows wrapping of Microsoft Windows Kernel API calls of your chosenkernel driver by your custom function code.

Although TraceFS was up to now used only for tracing of Windows NT CacheManager it can be easily used ever for any other NT kernel API tracing. Youneed to provide appropriate function wrappers in the main source file.Framework for thread synchronizations and debug tracing is provided to preventmangling of messages while running by multiple threads at once.
