加了userlist_enable=YES这句话就是说 在/etc/vsftpd.user_list中列出的用户名是不能使用ftp服务的。 userlist_deny=NO 这句官方的manpage中是这样写的“This option is examined if userlist_enable is activated. If you set this setting to NO, then users will be denied login unless they are explicitly listed in the file specified by userlist_file. When login is denied, the denial is issued before the user is asked for a password. ”也就和上面那个选项差不多的。
