Build a Secure FTP Dropbox with vsftpd

November 10, 2004


content_start FTP (
define) servers are wonderful things. They are quick to set up and endlessly useful. It's a quick and easy way for users to share files. Businesses that depend on large file transfers, such as printers and design houses, should use FTP. You can set up an upload directory for customers in the hopes of training them to transfer huge files via FTP, instead of attached to email. And believe it or not, this is usually successful. The key to getting reluctant users to use FTP is to help them set up their FTP clients so that they can transfer files with just a few mouse clicks. (Y'all be sure to come next week for a detailed look at FTP clients.) The tricky part about running an FTP server is keeping it secure. FTP is an insecure protocol -- all traffic is sent in cleartext. So don't use it for sensitive documents. Of greater concern to hardworking sysadmins is the possibility of an attacker exploiting FTP server weaknesses to gain control of the entire system.
