Vsftpd configuration. The configuration file limits the vsftpd user Connection Control Configuration.
Vsftpd. ftpusers: located in the/etc/vsftpd directory. It specifies which user accounts cannot access the FTP server, such as root.
Vsftpd. user_list: located in the/etc/vsftpd directory. The user account in this file cannot access the FTP server by default. Access is allowed only when the userlist_enable = no option is enabled in the vsftpd. conf configuration file.
Vsftpd. conf: located in the/etc/vsftpd directory. Customize FTP server configurations, such as user logon control, user permission control, timeout settings, server function options, server performance options, and server response messages.
I commented out the root of fptusers and user_list during the settings so that the root account can access them. However, if it is a formal environment, do not perform this operation as much as possible, and the security will be much reduced.
