Free home networking software for linux

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.

The Torque Network Library project is a robust, secure, and easy-to-use cross-platform C++ networking API designed for high performance simulations and games.
It features a UDP- based connection architecture with DoS prevention functionality, different types of data guarantee, bit stream compression, server object replication and updating, and a simple, highly space efficient RPC mechanism.
It includes a deterministic application journaling replay function for eliminating hard to find networking bugs.
Main features:
- Portable
- Powerful RPC Support
- Lightweight and efficient - not intended to be a replacement for CORBA.
- Extremely easy to use - two simple macro definitions and youre done.
- No complex wrapper classes to work with - write and call your functions as you normally would, and TNL will take care of the rest.
- Robust UDP-based notification protocol
- Supports fixed or adaptive rate data transfer.
- Arbitrary sized packet window.
- Robust connection handshaking.
- Handles packet loss/out of order delivery.
- Networked Objects
- Instantiation of objects by name or ID.
- IDs are assigned to NetGroups, so that only objects relevant to a connection can be references.
- Event Support
- Unguaranteed, guaranteed unordered, or guaranteed ordered event delivery.
- Notification to the event when it has been received or dropped by a client.
- Ghost Support
- Most-recent state information is transmitted to clienst.
- Scoping of objects to only those clients for which they are relevant - this helps prevent cheating or data sniffing and makes dramatically more effective use of available bandwidth.
- Prioritization of state updates by arbitrary criteria, such as relative velocity, team, ownership, etc.
- Extensible Protocol Architecture
- Easy to extend the protocol, for instance, to transmit player move information with every packet, or add voice support.
- See Torque for examples of additional capabilities that could be added to the protocol.

jHomenet is a home automation application. jHomenet uses both X-10 and Dallas Semiconductor 1-Wire network sensors and devices to collect sensor data and control devices.
jHomenet project can be programmed to respond to events, including particular sensor data values or time-of-day events.
Enhancements:
- This is a binary only release that includes several changes.
- Most noticable is the change in the versioning format.
- This change, however, also includes a drastic change in the library versioning and dependency framework.
- Other changes include a revised EventLogger, some UI tweaks, and several new jhomenet-commons JUnit unit tests.
- Some significant changes were also made to the Ant build setup.

Network Configurator is a network configuration tool.
Network Configurator is user-level tool that aims to make network configuration more easy. It have command line and GTK+ interface.
Supported network types:
- Ethernet
- PPPoE
- PPTP
- Wi-Fi (no WEP and WPA for now)
- dialup

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.

Ruby Iptables NEtwork Displayer project draws an SVG from a Linux IP table generated by "iptables-save".

lisp-network-server is a simple framework for writing Common Lisp network applications.

lisp-network-server framework takes care of listening on the network, accepting the connection and starting a new thread with handler functions of your network aware application.
