Free network interface software for linux

KNetworkManager is the KDE front end for NetworkManager. KNetworkManager project provides a sophisticated and intuitive user interface which enables users easily to switch their network environment.

The range of functions encompasses the features implemented by NetworkManager daemon. Up until now NetworkManager supports:

Wired Ethernet Devices (IEEE 802.3)
Wireless Ethernet Devices (IEEE 802.11): Unencrypted, WEP, WPA Personal, WPA Enterprise
Virtual Private Network (VPN): OpenVPN, VPNC
Dial-Up (PPP)

How does it work?

For both, Wireless LAN and Wired LAN, NetworkManager supports devices known to HAL. Unless working in offline mode, NetworkManager tries to keep the system connected at any time. For this, NetworkManager follows the following policy.

Once started, NetworkManager asks HAL about available network interfaces. If a wired network interface with a carrier is found, NetworkManager connects to this. Either by DHCP (default) or by setting up previously defined static configuration. Later on, when KNetworkManager starts up, NetworkManager will expose its information about network devices and wireless networks found by scanning to the applet.

At this point, if a user decides to unplug the wired connection, NetworkManager will not connect to an arbitrary wireless network. By default all available networks are untrusted. Only if a user decides to connect to a network manually once, this specific network n henceforth being marked as trusted.

n = { ESSID, Hardware address or addresses of the access point}

The trusted networks are stored individually for each user. KNetworkManager stores them and informs NetworkManager about the known, trusted networks. If a wired connection drops due to unplugging the cable NetworkManager will automatically connect to a trusted network. As this step was done without user interaction, NetworkManager will reconnect to the wired connection once it has a carrier.

If a user joins a wireless network by manual intervention (e.g. user clicks on a network listed in the context menu of KNetworkManager or connects to a hidden wireless network), NetworkManager will take down any previous connection. If one unplugs the wired connection after such a step, NetworkManager will not connect to the wired connection once it has a carrier.

Java Neural Network Trainer is a neural network trainer with the ability to easily add new training algorithms and training patterns.

Java Neural Network Trainer project includes a parallel training graphical interface where you can view each trainer working in real-time in parallel.

Xnetintf is an X Windows application that manages network interfaces. The current interface state is depicted through a series of bitmaps, and a mouse click in the window initiates a state transition.
Xnetintf uses a per-interface configuration file to supply commands that check and toggle state, as well as a program to run after the state change completes. A command line interface is also supported.
Main features:
- current interface state described through series of bitmaps.
- mouse click on window initiates toggle of interface state.
- per-interface configuration file to specify commands to bring interface up / down, as well as a command (e.g. a shell script) to run after the state change has been completed.
- companion program -- ifsuex -- which permits safe root execution f an interface-specific command (like a stripped-down sudo).
- command line interface (i.e. can be run without X Windows).

OGDI is the Open Geographic Datastore Interface. OGDI is an application programming interface (API) that uses a standardized access methods to work in conjunction with GIS software packages (the application) and various geospatial data products.
OGDI uses a client/server architecture to facilitate the dissemination of geospatial data products over any TCP/IP network, and a driver-oriented approach to facilitate access to several geospatial data products/formats.
Enhancements:
- This release fixes some significant bugs in the VRF (VPF) driver.

network-config is a simple network configuration tool.

Network-config is a simple and easy to use program that helps configuring the network interfaces for linux-based operating systems. It allows to have multiple configurations for the same computer and to easy configure NAT for internet sharing.

It can also be used to scan for wireless networks. It is written in perl and uses gtk2+, but also works as a command line program.

poker-network project includes a poker server, a client library, an abstract user interface library, and a client based on it.

The server deals the cards and checks the user actions using a poker game engine (poker-engine). It listens on a TCP/IP port and understands its own specific protocol. The persistent information is stored in a MySQL database.

The client library implements the poker-network protocol for the client. The abstract user interface library provides a framework based on the client library and suited to implement a user friendly client.

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.
