Free networking basics 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.

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.

My Network Catalog is an indexing engine that allows Windows shares (or Samba shares) to be bound together over a local network.

My Network Catalog allows an easy centralized search of all the files available over the network.

PerlPoint::Tags::Basic is a Perl module that declares basic PerlPoint tags.

SYNOPSIS

# declare basic tags
use PerlPoint::Tags::Basic;

This module declares several basic PerlPoint tags. Tag declarations are used by the parser to determine if a used tag is valid, if it needs options, if it needs a body and so on. Please see PerlPoint::Tags for a detailed description of tag declaration.

Every PerlPoint translator willing to handle the tags of this module can declare this by using the module in the scope where it built the parser object.

# declare basic tags
use PerlPoint::Tags::Basic;

# load parser module
use PerlPoint::Parser;

...

# build parser
my $parser=new PerlPoint::Parser(...);

...

It is also possible to select certain declarations.

# declare basic tags
use PerlPoint::Tags::Basic qw(I C);

A set name is provided as well to declare all the flags at once.

# declare basic tags
use PerlPoint::Tags::Basic qw(:basic);

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.
Enhancements:
Updated translations:
- gl (Ignacio)
- it (Alessio)

Noname Network provides a powerful file-sharing network.

The Noname network is a gnutella-based network that features a different and more flexible protocol. The client and network currently support filesharing, but the protocol can be extended to support more features.
