编辑然后保存现有文件时，文件权限从755更改为655.以下是smb.conf文件内容：
[global]
protocol = SMB2
[root]
comment = the whole file system
read only = false
locking = no
path = /
hosts allow = all
writeable = yes
browsable = yes
create mode = 0644
directory mode = 0755
guest ok = yes
public = yes
我需要告诉samba不要更改任何文件权限。只是在创建文件时使用我在smb.conf文件中指定的权限。
