Free round trip time in wireless network software for linux

Gnome Wireless PC Lock is a Gnome applet that locks your desktop when you walk away from your desk.

A small gnome program that locks your desktop when you walk away from your desk. It is tested with a Sitecom cn-129 Wireless PC Lock.

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

KWirelessMonitor is a small KDE application that docks into the system tray and monitors the wireless network interface. It supports both Linux (tested on several major distributions) and FreeBSD (tested on 5.2.1).
I wrote this because I like the compactness of the Wavelan/Orinoco monitor in Windows. The KWirelessMonitor systray icon shows the signal quality and the bit rate using a "bar graph" and a "pie chart", respectively.
The tool tip also displays the network name (ESSID) and the power management mode. In the configuration dialog, you can change the bit rate and power management settings of the wireless interface.
It is also able to automatically enable power management when using battery power and/or automatically disable power management during data transfer. By default, it tries to automatically detect the wireless interface.
You can also manually set the interface name if necessary. Experimental: Starting with version 0.5.91, KWirelessMonitor can connect to a network specified by the user (currently only supports unencrypted networks).
Installation:
If you want to install from source, you can do the following in the top level directory (kwirelessmonitor-x.y.z):
./configure --prefix=
make
make install
A few notes:
1. < your_KDE_base > is the base directory in which KDE is installed (/usr for Red Hat/Fedora, /opt/kde3 for SUSE, or try the output of "kde-config --prefix"). This must be set correctly (otherwise the application will not be able to find the icons).
2. If the application builds successfully but it always says "No signal", it is quite possible that your glibc kernel headers and your running kernel are of different versions. You can check this by comparing /usr/include/linux/wireless.h and < your_kernel_source_dir >/include/linux/wireless.h.
3. On FreeBSD 5.2.1, it seems that the following is necessary:
./configure --prefix=/usr/local --with-extra-includes=/usr/local/include
--with-extra-libs=/usr/local/lib
Usage:
To start KWirelessMonitor, simply run the application, and it will dock into the system tray. By default, the application tries to automatically detect the wireless interface. If there are multiple wireless interfaces, the first one is selected. If necessary, you can manually set the wireless interface name by right click on the icon and select "Configure..." (see the screenshot above).
In the configuration dialog, the first time you switch to the "Settings" page, kdesu will ask for the root password, which is necessary for changing the bit rate and power management settings of the wireless interface. If you click "Ignore" or "Cancel", you will not be able to change the settings.
After the settings are enabled, the previously saved settings are immediately applied. Enabling settings and applying the previously saved settings can also be achieved by selecting "Enable Settings..." in the right-click menu. Mouse over the icon to see the tool tip, and left click on the icon to bring up the small status window (left click again to hide it).
Enhancements:
- Experimental: added support for connecting to a network specified by the user. User can enter the appropriate network name (ESSID) and click Ok/Apply to connect to the network. (Currently only supports unencrypted networks.)
Note: Tested on Fedora Core 2, Mandrake 10, and FreeBSD 5.2.1, which are supported by distribution-specific code. For other distributions, it falls back to generic code, which theoretically should work. However, given the quirks I have encountered in the above three distributions, there are likely problems with other distributions as well. Please test this feature and report problems if it does not work.

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.

GWireless is a simplist utility for managing wifi 802.11x wireless connections on FreeBSD.

GWireless enables you to connect to available networks without touching the ifconfig command by hand.

Asumptions:

- sudo available without pass
- wireless is ipw0 (if not, "ifconfig yours0 name ipw0")

This is a small application allowing you to scan for wireless networks and connect to them.
Wireless Assistant uses wireless-tools as its backend, so they need to be installed.
All feedback as well as hints and good advice are appreciated!
Installation:
make -f Makefile.cvs
./configure
make
su -c "make install"
Enhancements:
- NOTE: This release includes some brand new or rewritten features. Please submit bugs to sf.net page and comments/votes here. Thanks!
- NEW: Finally WPA-PSK support (WPA/WPA2, please test and report in case of problems!)
- NEW/FIX: Rewritten, completely new connection state detection (please comment!)
- NEW: Optional grouping of APs with the same ESSID
- FIX: UI refinements
- FIX: hide encryption keys in console output and edit dialogs
- FIX: Connection using dhclient fails
- FIX: dont check for connection while wizard is running
- FIX: remove default gateway upon disconnection if not managed by DHCP client
- FIX: updated Polish translation (with help from riklaunim)
- FIX: Many internal changes, more stable

KWifiSelector is a KDE tool to display all available wireless networks (WLAN). For each of them, the parameters (such as IP configuration and WEP keys) can be configured.
KWifiSelector also allows the user to connect to and disconnect from a selected network.
Enhancements:
- The root elevation mechanism was changed from using kdesu to sudo.
- This allows avoiding giving everyone the root password.

Multicast Dissemination Protocol project is a protocol framework and software toolkit for reliable multicasting data objects including files and application memory blocks. A primary design goal of MDP is to provide a reliable multicast protocol approach which is suitable for reliable dissemination of data over both wireless and wired networks.

MDP software has been demonstrated across a range of network architecture and heterogeneous conditions including; the worldwide Internet MBone, bandwidth and routing asymmetric network connections, high delay satellite networks, and mobile, radio networks. MDP integrates numerous multicast protocol advances including highly robust, packet-based erasure correction techniques and adaptive group timing mechanisms.

The present MDP software toolkit includes a library with a well-defined API. Several example working applications including a multicast file transfer applications and a very basic multicast chat application are also provided. To learn more and/or download the software see the following sections.
