User access to the FTP server directories and files is dependent on the permissions defined for the account used at login. If you are looking to transfer files securely see SFTP in the section on OpenSSH-Server. This latter choice is very insecure and should not be used except in special circumstances. In the Authenticated mode a user must have an account and a password. In the Anonymous mode, remote clients can access the FTP server by using the default user account called “anonymous” or “ftp” and sending an email address as the password. For the duration of the session it executes any of commands sent by the FTP client.Īccess to an FTP server can be managed in two ways: When a request is received, it manages the login and sets up the connection. It continuously listens for FTP requests from remote clients.
The server component is called an FTP daemon. So if you are here looking for a way to upload and download files securely, see the OpenSSH documentation instead.įTP works on a client/server model. In the past, it has also been used for uploading but, as that method does not use encryption, user credentials as well as data transferred in the clear and are easily intercepted. Multi-node configuration with Docker-Composeĭistributed Replicated Block Device (DRBD)įile Transfer Protocol (FTP) is a TCP protocol for downloading files between computers.
