Free ftp file transfer software for linux

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

FileRunner is a simple and efficient X11 file manager for Unix. It has built-in FTP support and is very configurable. FileRunner was created to ease you from the burden of typing thousands of "ls", "cd", "mv", "rm" and "cp" in a day just to get your work done.

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.

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.

FTP Index provides a FTP indexer and search engine.
FTP Index is a search engine for FTP servers. It scans servers for definable filetypes and stores the results in a MySQL database.
It utilizes the ftpls tool from the ftpcopy package for indexing the servers.
It scans multiple servers at the same time by running with multiple processes.
Enhancements:
- fixed a nasty bug that caused the loss of the half all found files.

FTP Monitor is a simple panel applet, which monitors incoming connections to ftpd(vsftpd/ncftpd/pure-ftpd/proftpd) and generates passive popups.
For pure-ftpd, ncftpd, proftpd it acts as a frontend to pure-ftpwho, ncftpd_spy and ftpwho respectively. For vsftpd, it looks in output of ps -fe.
Enhancements:
- Update the change in ftp daemon (or path) withour requiring a restart
- Fixed the bug (introduced in 0.70) that FTP status will not update
- For large panels, the icon is now centered

Pure FTP Server is a fast, production quality, standards-conformant FTP server based on Troll-FTPd. Pure FTP Server has no known vulnerability, it is trivial to set up, and it is especially designed for modern kernels.
Features include PAM support, IPv6, chroot()ed home directories, virtual domains, built-in ls, FXP protocol, anti-warez system, bandwidth throttling, restricted ports for passive downloads, an LDAP backend, XML output, and more.
Beginners can install a Pure-FTPd server in 5 minutes. It can be as simple as installing the package, typing "pure-ftpd &" and... thats all. You already have a running server, and clients can start to connect.
Theres no need to review any long and complex configuration file, where possible mistakes could have security and reliability implications. Pure-FTPd uses simple command-line switches to enable the features you need.
You can limit the number of simultaneous users, limit their bandwidth to avoid starving your ADSL or cable-modem link, hide system files (chroot), have upload/download ratios, and moderate new uploads.
Custom messages can be displayed at login-time (even changing fortune files) and when an user enters a new directory. Also, to avoid your disks being filled up, you can defined a maximal percentage, and new uploads will be disallowed once this percentage is reached.
The FXP (server-to-server) protocol is implemented. It can be available for everyone, or only for authenticated users.
Kiddies are using common brute-forcing tools that are trying to discover hidden directories. Pure-FTPd provides a protection against this. Anonymous access is secure by default. For instance, users cant access dot-files (.bash_history, .rhosts, ...) unless you explicitely enable this.
And to watch whos doing what, the pure-ftpwho command shows a table with currently active sessions, how much bandwidth is taken by every user, what files they are uploading or downloading, where they are coming from, etc.
Enhancements:
- User names can now be up to 127 characters long.
- Compilation with PAM support has been fixed on Mac OS X, and the MySQL PASSWORD() function can now be used with MySQL >= 4.1.
- Logging now has the correct timezone.
- Support for charset conversions (RFC2640) has been implemented. Large files are now handled by default, using sendfile64() if possible. SITE UTIME and OPTS MLST have been implemented.
- MySQL queries can now include multiple statements and call MySQL 5 stored procedures.
- Transferring a lot of small files is now much faster than in previous versions.
