Professional software companies may also use anonymous FTP servers to distribute software updates. This was once a popular method of distributing software, and various publicly available shareware FTP servers existed. Anonymous FTP servers allow users to connect to an FTP server anonymously. Typically, a user account is required to access an FTP server. The general syntax for addressing Anonymous FTPįTP may be used anonymously. If the connection is made via the client integrated in the browser, the FTP server is addressed in the URL line of the browser. With a standalone client like FileZilla, the data only needs to be entered once in the designated fields and can be stored there. To establish a connection, users need the FTP server's address, the port number, and the relevant user name and password. Screenshot of as an example of an FTP client provider. Such a client is usually a GUI program or app that enables users to connect to and then transfer files between their local machine and the server. To access an FTP server, an FTP client is required. The data type can be set, which can help make data transfers more efficient depending on what is being transferred, as well as the file structure and data transfer modes.Įstablishing a connection to the FTP server by the user FTP uses two ports: one for sending data, and one for receiving data. The File Transfer Protocol may run in one of two modes, active or passive, which determines how data transfers are initiated between client and server. The difference is, FTP was built to handle large file sizes, whereas HTTP is better optimized to handle multiple, smaller file transfers. HTTP and FTP work very similarly, in that they both enable the transfer of data from a client to a server and vice versa. For example, when connecting to a website, data is transferred over the Hypertext Transfer Protocol (HTTP). Each protocol is tailor-made for its specific use case. Every time a computer connects to another, it does so using a specific protocol, which is a method of efficiently transmitting data. The File Transfer Protocol is simply a dedicated protocol for sending files between a client and a server. FTP servers often support fine-grain access permissions, so it is possible to mark specific folders as download only, restrict access by user account, or otherwise restrict access in some way. FTP servers can be set up to contain important company documents that can be downloaded any time by employees. It used to be the main method of deploying new websites, though, with the rise of cloud storage, it has been largely superseded by other transfer methods, such as automatic deployment from source control.įTP can also be used as a way to transfer large files. The process is the same to the end-user, but SFTP adds additional security measures that are not included with FTP, so there is no benefit to not using SFTP if it is supported by the server.įTP can be used to deploy websites to servers and make changes to files on live servers. Even when security is not a priority, it is recommended to use SFTP over FTP where possible. SFTP can be useful for a number of situations, particularly when privacy is required, such as when transferring data containing sensitive information. SFTP encrypts files during transfer so that others cannot see which files you are transferring or their contents. It is built on top of the same FTP technology but includes SSH (Secure Shell) components, to increase security. SFTP stands for Secure File Transfer Protocol. This can cause privacy issues with sensitive files, so a secure version called SFTP exists. This means that the data that is transferred between a client and server is not encrypted, and can potentially be read or modified by a third party. It is still a popular means of storing and accessing large files, particularly on intranets.īy default, FTP is not secure. Although it has fallen out of favor in modern times, it used to be commonly used by web developers to upload files to a server when creating a website.
