    VSFTPD stands for "Very Secure FTP Daemon" is a GPL licensed FTP server for UNIX systems. It supports IPv6 and SSL. vsftpd supports explicit (since 2.0.0) and implicit (since 2.1.0) FTPS. vsftpd is the default FTP server in the Ubuntu, CentOS, Fedora, NimbleX, Slackware and RHEL Linux distributions. It is secure and extremely fast.

     It is stable. VSFTPD is a mature and trusted solution which 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 such as SSH or SMTP.

    root@linuxstorage:~#yum install vsftpd* -y

    First install vsftpd and relative packages using yum command.

    root@linuxstorage:~#vim /etc/vsftpd/vsftpd.conf

     # Allow anonymous FTP? (Beware - allowed by default if you comment this out).
    anonymous_enable=YES

     Check line number 12 in configuration. Enable anonymous_enable=YES by removing # symbol in front of it.

    root@linuxstorage:~#service vsftpd restart

    After changing the configuration restart and enable chkconfig service for ftp.

    root@linuxstorage:~#chkconfig vsftpd on
