Can you believe that in nearly four years of Paranoid Penguin columns, I've never talked about how to configure FTP services? This month I fix that, using my new favorite FTP server, Chris Evans' excellent vsftpd (Very Secure FTP Dæmon). Because my space here is limited and the best use of FTP is anonymous FTP, we focus on anonymous FTP. The FTP protocol's use of clear-text authentication makes it a terrible choice for anything but anonymous file transfer. But anonymous FTP is still plenty useful.
