Free network speed test software for linux

Network Transparent Widgets short from NTW, is a protocol and application framework that allows a single server to serve thousands of remote GUI applications.
The client applications are nearly indistinguishable from local, native applications. The protocol is language and architecture neutral. Server language bindings for C and Java are in heavy development.
Main features:
Speed: Remote apps can run at a speed which is nearly indistinguishable from a locally running application. Since the client draws the widgets natively, its not necessary to transfer graphical data, only widget state data. This can be done asynchronously, so the responsiveness of the UI never suffers.
Persistence: Its just as easy to write the ntw protocol data to disk as it is to the network, so the state of the entire gui application can be easily saved. This also happens transparently, so the developer doesnt have to spend any time loading and saving data. Also, if a network connection dies or the client computer loses power, the application can be restarted from the point of failure at the next connection.
Portability: using the protocol, an ntw server application running on a Unix machine could talk to an ntw client for Windows, and vice versa. So a developer could write a program on Linux that could be run from any OS without any porting necessary. Any language or platform that can read and write data to a network can use the protocol to create gui apps.
Scalability: Since the ntw server does not store or draw widget graphics, the memory and computational overhead of running an ntw application is much less than a comparable X Window application. A low end machine could easily serve hundreds of remote clients.
Productivity: Users can run ntw apps without installing anything but the client. Developers can release new versions of their apps without the users having to do anything, much like a web page.
Reference Implementation:
The current reference implementation of the client implements most of the widgets in the Gtk toolkit, and is written in C using the GTK+ 2.0 toolkit for drawing the widgets and handling events. It compiles and runs on FreeBSD, Linux, and Windows, and likely other Unix variants also. Youll need the GTK+ toolkit installed to run the client, and the GTK+ development headers to compile it.
The source code also include a server reference implementation and a sample server application. The "server" is really a set of C language bindings to functions that create and send ntw widget data. The bindings can be used in much the same way as any other GUI toolkit. See the file "ntwtest.c" for the example application. Its been tested on FreeBSD, Linux, and Windows XP. The server library should compile and run on most systems with a C compiler and support for sockets, without the need for any additional libraries.
The protocol is defined by the two header files, ntw.h and ntw_signals.h. These are C header files that describe exactly the byte layout for each of the widgets and all of the opcodes and events that can be sent.
There are still some widgets missing, and some of the signals raised by GTK are not yet handled in the protocol. This will be fixed in the near future.
Note: Although the reference implementation is coded in GTK, the NTW protocol is designed to be independent of any particular widget toolkit. GTK was picked due to favorable design features and a favorable license.
Enhancements:
- 02JUL06 - Fixed bug in update.c where spin_button was switched with slider
- 02JUL06 - Removed status field from image_buffer widget protocol

Manage your network with a free Network Monitoring Software application.
Network Management Tool is an organized way to manage your network. 100% web-based network management.
Manage your network devices with ease. 100% Free Network Managment Software! Manage all your network devices, routers, switches, firewalls, hubs, and more.
Enhancements:
- A display bug that occurred when viewing the comments on a device was fixed.

Network Tracker and Management is a Web-based network management application.
Network Tracker and Management can store information about all of your network devices, and allows you to track all changes and updates made to the device.
Having this information readily available will enhance your ability to troubleshoot network problems.
Enhancements:
- The documentation was updated to include more details on the setup of the database for the network tracking system.

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 Network Security Monitor Daemon is a lightweight network security monitor for TCP/IP LANs. It will capture certain network events and record them in a relational database. The recorded data is available for analysis through a CGI-based interface.
You can run test version with ./Monitord, just to see how it works. Production version should be run in background, v.g. with nohup ./monitord &. Both versions will accept a device name as a parameter (default: eth0). You can send them SIGHUP at any time to print some stats. If you send SIGTERM, SIGQUIT or SIGINT, all threads will end gracefully.
Enhancements:
- Linux Kernel with "packet sockets" and "socket filtering" support.
- GNU C Library 2 (glibc2) with LinuxThreads support. (integrated in most recent versions).
- Full MySQL, including headers and libmysqlclient_r.
- GNU C Compiler (gcc).
- GNU Make (make).
- Perl (perl).
- Wget (wget).
Enhancements:
- Added chmod 4755 ... in Makefile
- Root should run make now, but not the daemon ;-)
- The daemon will drop root privileges as soon as possible
- (after creating the raw socket with an attached linux socket
- filter and putting the interface in promiscuous mode)
- No threads run with root privileges so its much safer
- (specially the new server thread which reads remote user input)
- Added stats thread
- To calculate/mantain exponential averages
- Added server thread
- It accepts HTTP requests and serves stats in XML

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.

Dell 1600n network scanner driver is a driver for network scanning using a Dell 1600n Printer/Scanner/Fax/Copier.
It is implemented as a Perl script. In principle, this means that it should be cross-platform.
It has been tested under Linux (Debian) and Windows (NT4 with Cygwin) on Intel. Supported formats are TIFF and JPEG. With an external program (e.g. ImageMagick convert), PDF is supported.
Main features:
- TIFF and JPEG network scanning using a Dell 1600n MFP.
- PDF scanning support via an external program (eg: ImageMagick convert)

Speedometer project is a console bandwidth and file download progress monitor with a logarithmic bandwidth display and a simple command-line interface.

Usage:

speedometer [options] tap [[-c] tap]... Monitor network traffic or speed/progress of a file transfer. At least one tap must be entered. -c starts a new column, otherwise taps are piled vertically.

Taps: filename [expected-size] display download speed [with progress bar] -rx network-interface display bytes received on network-interface -tx network-interface display bytes transmitted on network-interface

Options: -i interval-in-seconds eg. "5" or "0.25" default: "1" -p use plain-text display (one tap only)
