QFtpServer is an event-driven server which is written entirely in Qt. It is non-blocking and supports multiple connections.

This project started because I couldn't find a free FTP server for my Symbian phone so I decided to try and make one of my own. I've tested it against Filezilla, Chrome, Firefox, Safari, Windows Explorer, and others.

It supports:

• Active connections (PORT command).
• Passive connections (PASV command).
• Random access for files (APPE, RETR), so stopped uploads and downloads can be continued.
• Secure FTP, also known as FTP-ES which uses SSL/TLS sockets.

It doesn't support:

• IPv6.
• FTPS (this standard is obsolete and FTP-ES should be used instead).
• Multiple user accounts.

server = new FtpServer(this, "/ftp/root/path", 21, "MyUserName",
                       "MyPassword", false, false);

It supports:

• Windows
• linux
• android
• Symbian phone
