/home/kefu 显示对U=kefu有rwx权限，为什root么使用FTP通过kefu登录192.168.235.100后，无法把192.168.235.20中的/root/2.java 上传给192.168.235.100中的/home/kefu文件夹 提示553
chroot_local_user
If set to YES, local users will be (by default) placed in a chroot() jail in their home directory after login. Warning:
This option has security implications, especially if the users have upload permission, or shell access. Only enable if
you know what you are doing. Note that these security implications are not vsftpd specific. They apply to all FTP dae‐
mons which offer to put local users in chroot() jails.
如果设置为YES，本地用户登录后将被（默认）置于其家目录的chroot()监牢中。警告： 此选项涉及安全隐患，特别是当用户拥有上传权限或shell访问权限时。仅应在明确操作后果的情况下启用。需注意这些安全隐患并非vsftpd特有，所有提供将本地用户置于chroot()监牢的FTP守护程序均存在此类问题
allow_writeable_chroot
Allow chroot()'ing a user to a directory writable by that user. Note that setting this to YES is potentially dangerous.
For example, if the user creates an 'etc' directory in the new root directory, they could potentially trick the C
library into loading a user-created configuration file from the /etc/ directory.
Default: NO
allow_writeable_chroot 允许将用户 chroot() 到一个该用户可写的目录。请注意，将此设置为 YES 存在潜在危险。 例如，如果用户在新根目录下创建了一个 ‘etc’ 目录，他们可能会诱骗 C 库从该 /etc/ 目录加载用户创建的配置文件。
allow_writeable_chroot=YES
感觉说法有点问题，计划试一下
