VSFTPD (Very Secure FTP Daemon) is a Secure FTP server for unix/linux systems. It protects or encrypts transferred data using SSL. It is well known because of its security, performance and stability over other servers. Vsftpd supports virtual users with PAM (pluggable authentication modules). A virtual user is a user login which does not exist as a real login on the system in /etc/passwd and /etc/shadow file. Virtual users can therefore be more secure than real users, because a compromised account can only use the FTP server but cannot login to system to use other services. You can put your virtual users into a local db or myql db. This guide is for RHEL/CentOS 5/6 and focuses on mysql based ftp authentication.
