ProFTPD (FTP server)

Here is the English translation of the ProFTPD server description with its three main features, addressing users with "you":

Centralized and Flexible Configuration

ProFTPD uses a single main configuration file, usually located at /etc/proftpd.conf on Linux. This file allows you to manage all server settings and directives. For example, you can easily define restrictions on simultaneous connections, configure virtual users, or set up multiple virtual FTP servers. The configuration style is inspired by Apache server settings, making it intuitive for administrators familiar with such environments.

Security with TLS/SSL Encryption

ProFTPD includes the mod_tls module, enabling you to encrypt data transfers between the server and FTP clients. You can activate TLS/SSL to secure file transfers and login sessions, protecting your data from interception or unauthorized access. Support for SSL/TLS certificates ensures that your users can connect securely, which is essential in professional environments.

Advanced Features and Modularity

The server offers advanced capabilities such as per-directory configuration similar to Apache's .htaccess files, support for virtual users who might not exist at the system level, and the ability to run multiple virtual FTP servers on a single machine. Its modular architecture allows easy extension with additional modules, including integrations with SQL databases, LDAP, SSL/TLS encryption, RADIUS, and IPv6 support.

These features make ProFTPD a reliable and powerful choice for managing FTP servers on Linux, suitable for both small setups and complex infrastructures requiring high security and customization.
