Free networking tricks software for linux

Understanding computer networks without performing practical experiments is really difficult, not to say it is almost impossible. Unfortunately, setting up a networking lab can be very expensive.

Netkit has been conceived as an environment for setting up and performing networking experiments at low cost and with little effort. It allows to "create" several virtual network devices (full-fledged routers, switches, computers, etc.) that can be easily interconnected in order to form a network on a single PC. Networking equipments are virtual but feature many of the characteristics of the real ones, including the configuration interface.

Netkit exploits open source software (mostly licensed under GPL) and is heavily based on the User Mode Linux (UML) variant of the linux kernel. The purpose of this project is to solve many of the difficulties and technicalities that a user could have in using UML for networking. We offer the users an easy-to-use-and-install package, which at the same time implements effective network emulation. Further, we provide a corpus of teaching material that can be used for courses at different levels.

Java Network Stack provides a Java library for research oriented network programming.

Java Network Stack is a library used by the DIMES project to create new internet measurements. It provides a clean API for packet manipulation, send, receive, filter, and analysis. It is a unification of raw socket capabilities, MAC level networkingm, and IPv6 capabilities.

Network Traffic Analyzer analyzes the network traffic on multiple network devices and creates HTML statistics with some network usage graphs. Sometimes it is good to know, how the network is used, how many bytes were received and how many bytes were sent.Therefore, here is Network Traffic Analyzer, which creates simple network usage statistics.


Such statistics can tell you, how good your network connection really is (who cares about what Internet provider say, when was the network down, which time is the best time for downloading large packages of data etc. etc. Or with this software you can just better imagine, how many traffic can your home computer generate.

LUA is a small scripting language designed to be embedded inside your application to provide extensibility.
It is also possible to extend the Lua scripting language itself via the use of extensions written in C. This page describes such an extension which provides a small number of basic networking and filesystem primitives.
By installing this extension you will be able to write networking applications in the Lua!
Enhancements:
- Added some filesystem primitives.
- Added API documentation & examples.
- The HTTP server now falls back to a default virtual host if none is specified, or if the attempted one doesnt exist.
- The HTTPD server now supports directory indexing if no index.html file is found in a directory.
- The HTTPD server now writes access.log files to each virtualhost.

Network Simulator (Ns) is a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.
Ns began as a variant of the REAL network simulator in 1989 and has evolved substantially over the past few years. In 1995 ns development was supported by DARPA through the VINT project at LBL, Xerox PARC, UCB, and USC/ISI.
Currently ns development is support through DARPA with SAMAN and through NSF with CONSER, both in collaboration with other researchers including ACIRI. Ns has always included substantal contributions from other researchers, including wireless code from the UCB Daedelus and CMU Monarch projects and Sun Microsystems.
Enhancements:
- Major updates were made to the PackMime-HTTP HTTP/1.1 and WPAN modules.
- Solaris/Sun C compilation bugs were fixed.

GNOME Network is a set of client network-oriented tools, which currently contains a network information tool, a remote shell and desktop clients and a personal web server and a desktop sharing tool.
GNOME Network is Free Software distributed under the terms of the GNU GPL.
