Free router simulator rapidshare software for linux

GenChemLab is an OpenGL-based application intended to simulate several common general chemistry exercises. It is meant to be used to help students prepare for actual lab experience. It could also be used in cases where laboratory facilites are not accessible, for instance in K-12 schools or home schooling.

At present, supported experiments include titration, calorimetry, freezing point depression, vapor pressure, and spectrophotometry.

The SigmaPi Neural Network Simulator is designed for time-series processing and neural network research on Unix/X11. Since version 0.5, it uses the LSTM neuron model, the RTRL training algorithm and a heuristic learning rate adaptation based on local update sign-changes. It is GPL-covered, so you can use it for free (read the license for more information)

The current version runs with the Trolltech QT 3.x API and is therefore platform-independent.

SigmaPi is no end-user software. It allows the user to change every possible network parameter, and it wont tell you whether a setting is nonsense or not.

Snow Path Formation Simulator is a program that models the process of people forming very distinct, and yet not always altogether logical looking, paths in the snow as they walk across open spaces.

The evolving condition of the snow is displayed graphically. This project may eventually mature into a screensaver.

Kompass, for KDE and Linux, or others Unix (*BSDs, etc) with suport for KDE, is a digital metronome simulator, for musical studies. KPreg is free software, and was licensed under GPL.
Main features:
- Play sound in ever "tic" or "tac";
- Contains 20 LEDs;
- some diferent forms and controls of time change;
Enhancements:
- First public release. Beta state.

Gravetat is a gravity and electromagnetism simulator. It offers users the ability to create a universe with a few particles and then see how they interact due to the forces mentioned before. It uses its own 3D rendering engine (released under the branch libPunts).
Gravetat 3D
- Real-time simulation
- Own 3D rendering engine (libPunts)
- Random universe generator
- Exports to SVGZ format
- Win32, Linux and MacOSX ports
Gravetat 2D
- Real-time simulation
- Exports to SWF format
- Random universe generator
Enhancements:
- Autotools (automake and autoconf) support has been added.
- This version is again usable for further development.

Enas is a Perl script that can telnet to a Cisco router or switch, execute some command, and log the work on a file.

Easy Network Automated script can use a username/password or password/enable mode.

Yet Another Machine Simulator is a machine simulator which emulates the MIPS32 architecture CPU close enough. Should be fully compliant, but we cant claim that it is. It allows cross compilation with standard MIPS32 compiler back-ends.
YAMS also provides a very simple device interface to the simulated memory, disks, network interfaces, terminals and a real-time clock. There is also support for pluggable I/O devices. Pluggable devices are separate programs that implement the functionality of one or more devices and communicate with YAMS over a network or Unix domain socket.
Many features of YAMS are configurable. For example the number of CPUs can be configured. When the number of CPUs is more than one, YAMS simulates an SMP machine. The devices are also configurable. For example various delays for disks, terminals and network interfaces can be set.
YAMS also provides a hardware console which can be used to debug programs. The hardware console can be used to set breakpoints and dump the contents of registers, TLBs and memory. The memory dumping functionality also contains a disassembler.
Performanc:
The purpose of YAMS is to provide a very simple yet realistic simulated hardware platform for educational purposes. High performace (i.e. high clock speed) was not a factor in its implementation, so a normal slowdown factor between host clock speed and simulator clock speed is in the order of 500, resulting in simulator clock speeds of only a few megaherz.
So if you are looking for a fast MIPS emulator/simulator, then YAMS is not for you.
Enhancements:
- Better portability with pthreads and printf formatting macros.
- Minor bugfixes.
