Anonymous FTP (File Transfer Protocol) is a method that allows users to access public files on a remote server without needing a personal username or password. Instead, users log in with the username "anonymous" or "ftp" and typically provide their email address as a password (though this is often not verified). This system is designed for distributing files to a wide audience, such as software updates, documents, or media.

Here’s how it works:

• Server Setup: The hosting provider configures a specific directory on the server as publicly accessible.
• User Access: Anyone can connect using an FTP client or web browser and the anonymous credentials.
• File Interaction: Users can download files from this directory but usually cannot upload, modify, or delete them unless explicitly permitted.

Key considerations for using anonymous FTP include:

• Security: Since it’s open to the public, ensure sensitive data is never stored in anonymous FTP directories. Use firewalls and regular monitoring to prevent abuse.
• Bandwidth: High traffic can consume server resources, so hosting plans may need adequate limits.
• Alternatives: For more secure file sharing, consider SFTP (SSH File Transfer Protocol) or password-protected FTP, which offer encryption and user authentication.

Anonymous FTP remains a simple, legacy tool for public file distribution, but modern hosting often favors safer methods. Always consult your hosting provider’s guidelines to configure it properly and protect your server.
