楼上兄弟,你这vsftp配的,如果不加chroot_local_user=YES,相当于把整个机子给人家ftp了

chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list

？？
这样不一样吗？反正匿名的时候能把用户ftp限制在家目录的

复制代码

/etc/vsftpd.chroot_list中的内容为：
cat /etc/vsftpd.chroot_list
ftp
upload

ftp是默认的匿名登陆用户，我新建了upload，并设置了密码，uploade的家目录是/var/ftp/upload
现在匿名能登陆，并且只能下载，满足了我的要求
可是upload还是不能登陆（当然密码是100％正确的）：
尝试 127.0.0.1:21
已连接到 127.0.0.1:21
220 Welcome to LB's FTP service.
USER upload

331 Please specify the password.
PASS xxxx
530 Login incorrect.
正在断开与站点 127.0.0.1 的连接

你还anonymous_enable=NO呢!
人家允许匿名用户下载啊!
