Free file transfer 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

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.

KSendfile is a native SAFT client. Compared to the Bitnet up to now there was no asynchronous file transfer service defined in the Internet. The existing standard file transfer, the ftp, is a synchronous service: an interactive login on both ends of the file transfer is mandatory for the user to set up a connection between both points.
If a user A wants to send a file to user B they have the following choices:
- ftp to a recipients account B
In this case one has to know the password of the recipients account. If A and B are not the identical person, severe questions of security arise and it is not the method of choice. Even if account A and B belong to the same person, the typed ASCII password characters for ftp access will travel open (readable) as ordinary TCP packets through the network.
- ftp using an anonymous ftp server
The file has to be uploaded by A onto the anonymous ftp server using an ftp session. After that A has to notify B about this using e-mail informing this user about the fact that the file is ready for download now. B can get the file now by doing another ftp transfer. This procedures requires a common reachable ftp server, with an upload (write access) facility. During the time the file resides on the anonymous ftp server it is open to anyone, it may be readable, writeable, changeable or erasable.
- sending a file via e-mail
A is sending a file to B enclosed into an e-mail. According to RFC 822 a mail must contain characters from the NVT-ASCII character set, which is a subset of the 7 bit ASCII character set. The file transfer via e-mail is limited to English text documents or the text to be sent must be encoded properly, of course using the NVT-ASCII character set. Encoding procedures like uuencode or MIME are available. It is not a pleasure to use either of them, they dont support all file ownership attributes and they will enlarge the amount of data to be transferred by encoding. In addition to this most of the existing MTAs are not designed to handle large amount of data transfers.
To avoid all the described disadvantages the SAFT-protocol (Simple Asynchronous File Transfer) has been developed and the sendfile software has been created as a reference implementation for UNIX platforms.
Enhancements:
- Fixed a bug in ksendfilenetclient::sendFile when getting status code 531
- Added Resend Function
- Fixed bug in ksendfilenetclient::sendfile in the date function
- Now sends the file date, not the actual system date.

Transfer to Media Device is a script that creates a new Playlist Right Click Menu item for transferring selected playlist items to your iPod via the Media Device Browser.
This script now also supports generic copy to operation for USB mass storage devices. Currently the script will prompt for a destination directory on first copy, in the future this setting will be saved in a configuration file.
This script works with amaroK 1.3beta3 and above.
Usage:
Run from the amaroK script manager. A new menu item will appear in the Playlist right mouse button menu.
Select files in the playlist and Right click -> Transfer to -> iPod for transfering to an iPod.
Select files in the playlist and Right click -> Transfer to -> USB Device for transfering to a USB device.
Enhancements:
- Add support for Creative Nomad Jukebox devices using the kionjb kioslave. Thanks to Ralf T for the patch.

SSH Filesystem is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side theres nothing to do. On the client side mounting the filesystem is as easy as logging into the server with ssh.
The idea of sshfs was taken from the SSHFS filesystem distributed with LUFS, which I found very useful. There were some limitations of that codebase, so I rewrote it.
Main features:
- Based on FUSE (the best userspace filesystem framework for linux ;-)
- Multithreading: more than one request can be on its way to the server
- Allowing large reads (max 64k)
- Caching directory contents
Installing
First you need to download FUSE 2.2 or later from http://fuse.sourceforge.net/. You also need to install the devel package for glib2.0. After installing FUSE, compile sshfs the usual way:
./configure
make
make install (as root)
How to mount a filesystem
Once sshfs is installed (see next section) running it is very simple:
sshfs hostname: /mountpoint
Note, that its recommended to run it as user, not as root. For this to work the mountpoint must be owned by the user. If the username is different on the host you are connecting to, then use the "username@host:" form. If you need to enter a password sshfs will ask for it (actually it just runs ssh which ask for the password if needed). You can also specify a directory after the ":". The default is the home directory.
Enhancements:
- This release fixes a couple of rarely occurring crashes and some smaller bugs.

Thin SFTP Applet is a full featured Secure File Transfer Program. Thin SFTP Applet can be use for secure file transfer and management and can be easily integrated into your website or web application.
You can use our SFTP applet to carry out recursive folder uploads and downloads, with entire directory trees being transfered in a single click.
Interrupted transfers can be resumed. Unlike the FTP protocol, with SFTP all data and commands are encrypted for maximum security.
In spite of being a web client, its appearence is no different from a traditional 2-Table File Transfer Program for desktops.
Because the client is an applet it does not need to refresh itself each time a file transfer or any other operation takes place. The result is that the user experience is no different from using a desktop client.
Enhancements:
- A minor bug related to connection pooling and reuse was fixed.
