Open Source FTP

Open source FTP clients
The always-excellent Blogzilla, a blog about Mozilla, mentions a free, open FTP client that hooks into Firefox: fireFTP. It sounds OK. In fact, after reading some of the comments for the blog entry, OK is pretty much accurate. I mean, it sounds cool to check out, but it also sounds like a lot of features are missing at this point. I hope the developers keep working on it so that one day I can wholeheartedly recommend it. In the meantime, if you need a good, free, open source FTP client for Windows, you should hie thee over to FileZilla & download it. It's good - real good. Most importantly, it does SFTP, which is all that I'll use (FTP ain't safe).
Open Source FTP Benchmark
Dkftpbench is an FTP benchmark program inspired by SPECweb99. The result of the benchmark is a number-of-simultaneous-users rating; after running the benchmark properly, you have a good idea how many simultaneous dialup clients a server can support. The target bandwidth per client is set at 28.8 kilobits/second to model dialup users; this is important for servers on the real Internet, which often serve thousands of clients on only 10 MBits/sec of bandwidth. The final result of the benchmark is "the number of simultaneous 28.8 kilobits/second dialup users". To estimate this number, the benchmark starts up a new simulated user as soon as the last one has finished connecting. It stops increasing the number of users when one fails to connect, fails to maintain the desired bandwidth, or the limit specified by the -n option is reached.
freeware FTP Client
Filezilla is a totally free Open Source FTP client but what is an FTP client? FTP client is an Internet application that allows access to a remote computer over the Internet using the File Transfer Protocol. FTP allows transfer of files between two remotely located computers as they are on your desktop. You will need an FTP client if you are building web sites and your web server is located in a remote data-center away from your office or home. If you are looking for a small, fast, simple, well designed, multi language FTP client software -- FileZilla is all you need and it is totally free as well. The latest version of this no bullshit FTP client -- FileZilla is also getting more stable as compared to the previous release that I have tried. FileZilla is a powerful full-feature Open Source FTP-client designed to be easy to use, fast and reliable. It is compatible with most current versions of Windows Operating System including Windows 95, 98, ME, NT4, 2000 and XP.
Open Source FTP Java Library
EdtFTPj is the first choice of Java developers worldwide for incorporating FTP functionality into their applications. edtFTPj is Open Source, licensed under the LGPL, the GNU Lesser General Public License. This means you can freely embed edtFTPj into your commercial Java applications, subject to the normal LGPL restrictions. Unrestricted (non-GPL) source licenses can be also be purchased. edtFTPj has been downloaded over 100,000 times since its first release, and is in use in thousands of companies worldwide. EditFTP Feature:* Widely used throughout the world in thousands of projects. * Full source code is provided.
* Passive and active modes are supported (PASV and PORT).
* Resuming of interrupted binary transfers supported.
* Now compatible with Java 1.1.x, so can be used in applets and many handheld devices.
* Under the LGPL, so it can be embedded in commercial applications.
* Unrestricted licences are also available for low cost.
The Open Source FTP Server
ColoradoFTP is the open source Java FTP server. It is fast, reliable and extendable. Fully compatible with RFC 959 this implementation makes it easy to extend the functionality with virtually any feature. Well commented source code and existing plugins make it a real pleasure to build the FTP server of your choice. The original FTP server implementation was developed in November of 2003. It was created just to restrict upload of JSP pages onto my servers by domain owners. The FTP was slow, but stable. The prototype worked for 3 years without major problems serving 2 FreeBSD servers. The only drawback it had was the maximum connection speed of 200 KB/sec. Under impression of the benchmarks I took in March of 2006 (connection and hard drives throughputs) I decided to reimplement the prototype, make it more robust, flexible and available to internet community. That is how ColoradoFTP was born.
EBA goes Open Source with FTP
Today we quietly open sourced EBA FTP Sync, a COM based file synchronization tool that more than a few people are using to perform tasks like automated backups. The neat thing about FTP Sync was always that we packaged it as a web tool� perform FTP synchronization from a web app. neat idea. We used it ourselves for years in our commercial CMS, which was a fairly elegant solution to the problem of migrating content efficiently between staging and production servers. We�ve decided that the component would be of more use to people if it shipped with the source code.. we thought about lowering the price and then remembered that we�re an Ajax company and had no business selling ActiveX tools in the first place.
File Transfer Protocol Server
FTP or file transfer protocol is a commonly used protocol for exchanging files over any network that supports the TCP/IP protocol (such as the Internet or an intranet). There are two computers involved in an FTP transfer: a server and a client. The FTP server, running FTP server software, listens on the network for connection requests from other computers. The client computer, running FTP client software, initiates a connection to the server. Once connected, the client can do a number of file manipulation operations such as uploading files to the server, download files from the server, rename or delete files on the server and so on. Any software company or individual programmer is able to create FTP server or client software because the protocol is an open standard. Virtually every computer platform supports the FTP protocol. This allows any computer connected to a TCP/IP based network to manipulate files on another computer on that network regardless of which operating systems are involved (if the computers permit FTP access). There are many existing FTP client and server programs, and many of these are free.
