Free data transfer meter software for linux

Fast Data Transfer is an application for efficient data transfers that is capable of reading and writing at disk speed over wide area networks (with standard TCP).
It can be used to stream a large set of files across the network, so a large dataset composed of thousands of files can be sent or received at full speed, without the network transfer restarting between files.
The project is written in Java, runs an all major platforms, and is easy to use.
Main features:
- Streams a dataset (list of files) continuously, using a managed pool of buffers through one or more TCP sockets.
- Uses independent threads to read and write on each physical device
- Transfers data in parallel on multiple TCP streams, when necessary
- Uses appropriate-sized buffers for disk I/O and for the network
- Restores the files from buffers asynchronously
- Resumes a file transfer session without loss, when needed

GNOME Transfer Manager allows the user to retrieve multiple files from the web.

These files can be retrieved in multiple parts and each part retrieved on a separate session that the user is connected to the Internet. This is most useful to users with dialup connections. The program performs these tasks using wget as its back-end.

The program supports CORBA. This makes it easy for other programs to use GTransferManager to handle the transfer of files from the Internet.

The program also has an applet which communicates with program using CORBA. The applet can launch the program, request for a new download or accept drops of URLs from netscape, gFTP, gmc and give these URLs to GTM.

Apple Disk Transfer ProDOS (or ADTPro for short) transfers diskettes and logical disk images between Apple ][-era computers and the modern world. If youre familiar with the original ADT, ADTPro extends ADTs reach by working with more logical disk formats, drive types, communications devices, and host operating systems.
Main features:
- Compatibility with any device ProDOS can read
- Compatibility with any Apple ][ (or clone) computer with 64k memory
- Compatibility with many logical disk image formats: .DSK, .PO, .NIB, 2IMG
- Server compatibility with original ADT client program
- Server compatibility with Windows, Mac OSX, Linux, and probably Solaris
- Ability to bootstrap an Apple ][ from bare metal over serial or cassette ports
- Ability to send floppies in "batch" mode without having to name each one
Server
The server program runs on a computer capable of running Java. Depending on how you want to connect to your Apple, you might also need a serial port and cables, an Uthernet card for your apple, or a couple of audio patch cables. The server offers a compact user interface that shows what communications are taking place between the host and the Apple ][.
The servers primary role is to send and receive disk images as requested from the client. But if you have recently acquired an Apple and a disk drive, and you have no software for it - youre in a bit of a tricky situation if you want to move software from the Internet all the way to your shiny new Apple. ADTPros server can help get you get bootstrapped.
Client
The client side runs on the Apple ][. It handles most of the user interaction. When choosing disks/volumes to transfer, anything that ProDOS can see is fair game. Transferring data occurs with a 20k buffer on the Apple, so all transfers are broken up into 20k chunks. A progress indicator shows how far it is into the current chunk, as well as a running count of the total progress.
Enhancements:
- This release has been enhanced with Jean-Marc Boutillon (Deckard)s FASTDSK fast Disk II reading routines.
- This results in a speed boost of 25%-33% for Disk II to host transfers.
- Bootstrapping operations have been reduced, as there is no longer a dependency on ProDOS BASIC.

Simple File Transfer is a pure useless program which allows you exchange files with remote computers via Internet. This program has been written for personnal use, so dont blame me if you think I am stupid doing such tool for the others.
It should run on every POSIX compliant Operating System, but I cant give you any complete list.
If you want to compile it under *BSD, maybe youll have to disable the uname() call by running the configure script with the --with-uname=no option.
Enhancements:
- Added the support of hostnames for the destination server

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

The "Open Device Monitoring and Tracking Protocol", otherwise known as OpenDMTP, is a protocol and framework that allows bi-directional data communications between servers and devices (clients) over the Internet and similar networks.
OpenDMTP is a highly configurable and extensible protocol for communicating with mobile devices.
OpenDMTP is particularly geared towards Location-based information (LBS) such as GPS, as well as temperature and other data collected in remote-monitoring devices. OpenDMTP is small, and is especially suited for micro-devices such as PDAs, mobile phones, and custom OEM devices.
We saw a need for a communications protocol that allowed high-latency, low-bandwidth (HL/LB) devices to transmit location data to monitoring-systems. Because these devices often have limited network connectivity, the protocol needed to be small and efficient. Example devices include mobile phones, PDAs, OEM micro-devices (alarm systems, temperature monitors, etc.), and more.
There are many mobile GPS tracking devices on the market today with their own closed proprietary protocols. Searching the web for open protocols revealed only a few available for transferring data (including GPS information) between devices. However these solutions are generally designed for non-mobile applications and/or lack some of the low-bandwidth, configurable, and extensible features that mobile applications require.
Main features:
- Small Footprint: Mobile devices typically have limited resources on which to run client code (ie. memory, processor speed). An open protocol designed with this in mind should be optimized to allow efficient implementation and should easily support devices such as PDAs, mobile phones, GPS monitoring devices, and other OEM micro-devices.
- Network Efficient: Mobile devices typically have limited network connectivity, and in some cases data communication can be quite expensive (e.g. satellite). Because of this the protocol needs to be efficient in its dialog between the client and server. The communication needs to be optimized such that the necessary information can be conveyed with a minimum number of bytes in the least amount of time.
- Bi-directional: Some devices can support two-way communication (ie. GPRS, or other socket based connections), while others may only support one-way communication (ie. some satellite communication systems). With this in mind, a protocol should be designed to support both duplex (two-way) and simplex (one-way) communication.
- Transport Media: Differrent mobile applications will have their own unique way of communicating data back to the server. Some may use GPRS, or socket based communication, others may use satellite communication, while still others may use other forms of wireless communication, such as BlueTooth. The design of the protocol should be able to encompass all such transport media types, regardless of the type of transport in use.
- Flexible Data Encoding: Most types of transport media allow for the transmission of binary encoded data. However, there may be some forms of media for which an ASCII encoded data packet is much better suited. A protocol designed with this in mind should be able to support both types of data encoding.
- Configurable Messages: Due to the broad range of data types used in mobile applications, the protocol should be flexible enough to define standard messages, yet still allow custom messages within the framework.
- Extensible: Not every mobile application is the same. Some require special handling and may have various types of inputs and outputs. A protocol designed for mobile applications should insure that the framework can be easily extended to incapsulate the specific needs of the device.
- Industry Compatibility: Having an open protocol insures better compatibility between different client devices and service providers.
- Reference Implementation: Having a reference implementation that showcases the major features of the protocol provides an easy starting point on which developers can add their own features and platform specific implementation without having to worry about how data gets from the client to the server.
OpenDMTP was specifically designed to suit all these needs, especially "Small Footprint" and "Network Efficiency". The typical data plan for GPRS communication, for instance, is usually 1Mb per month. OpenDMTP was designed to optimize packet encoding to allow the collection of GPS information packets once every 3 minutes, 24 hours a day, 30 days a month, and still stay under the 1Mb data plan limit.
While XML is very extensible, it fails the "Small Footprint" and "Network Efficiency" requirements. Thus, it was discounted as a viable protocol solution. Many mobile devices do not have the resources necessary to be able to provide full XML parsing functionality. And an XML packet may need to be several hundred bytes in length just to send a few bytes of actual data. This alone would make the solution cost prohibitive for high-cost transport media such as satellite.
OpenDMTP also includes a full-featured commercial quality reference implementation to jump-start development.
Enhancements:
- NEW: Minor optimizations made to message logging.
- FIX: Log file now properly displays account/device on client connection.

gnetload network load meter project is a network and ISDN load meter that is similar to xisdnload, but works in a distributed environment.
It includes an agent (devstata) that runs on machines with interfaces to be monitored and periodically sends status information over the network. A display program (gnetload) collects and displays the data.
Both can be run on the same machine, or be used to report on the state of a dedicated router on another machine. Using multicast or broadcast addresses, data can be fed to more than one instance of gnetload. A menu for taking network interfaces up and down is also provided.
Usage: ./gnetload [-I] [-t tickscale] [-g geometry] [-d] [ip]:port
Enhancements:
- The config script was updated to build with GTK2 and GCONF2 where available.
- There are no other code changes.
