我正在尝试设置一些客户端用户帐户，以便对我们的FreeNAS服务器进行FTP访问。
SFTP有效，但FTP没有。例如，我创建了一个client带有主文件夹的用户/mnt/raid-5x3/alpha/ftp/client1
但是当client1尝试登录时，服务器返回530 login incorrect并显示日志
Apr 19 20:53:51 whNAS proftpd[39911]: 192.168.1.99 ___ - notice: unable to use '~/' [resolved to '/mnt/raid-5x3/alpha/ftp/client1/']: Permission denied
Apr 19 20:53:51 whNAS proftpd[39911]: 192.168.1.99 ___ - chroot to '~/' failed for user 'client1': Operation not permitted
Apr 19 20:53:51 whNAS proftpd[39911]: 192.168.1.99 ___ - error: unable to set default root directory
我检查了权限：
