What is Ubuntu FTP Server 20.04?

Ubuntu FTP Server 20.04, also known as Pure-FTPd, is a free, secure, and lightweight FTP server for Linux-based systems. It is based on the File Transfer Protocol (FTP) and is widely used for transferring files between a client and a server over a network. Ubuntu FTP Server 20.04 comes with several features such as virtual users, chrooted home directories, TLS encryption, IPv6 support, and much more.

Virtual Users

Ubuntu FTP Server 20.04 supports virtual users, which means you can create and manage multiple users on the server without having to create a new system user account.
