无法在 Windows 7 上使用 Cygwin 设置权限

我在 64 位 Windows 7 计算机上安装了 Cygwin 1.7.34(0.285/5/3)，但我发现无法通过它控制计算机上文件/目录的权限chmod。大多数文件/文件夹的权限似乎都固定在-rw-r--r--。

这对我来说是一个问题，因为我的工作站上的目录权限不正确~/.ssh可能是最终导致我与服务器建立无密码 ssh 连接时遇到的一个相关问题。

这是我~/.ssh现在的权限：

$ ls -la .ssh/
total 30
drwxr-xr-x 1 davidfallah Domain Users    0 Mar 19 08:21 .
drwxr-xr-x 1 davidfallah Domain Users    0 Mar 18 15:17 ..
-rw-r--r-- 1 davidfallah Domain Users  405 Mar 18 17:26 authorized_keys
-rw-r--r-- 1 davidfallah Domain Users 1675 Mar 18 18:00 gitolite-admin
-rw-r--r-- 1 davidfallah Domain Users  405 Mar 18 18:00 gitolite-admin.pub
-rw-r--r-- 1 davidfallah Domain Users  672 Mar 18 17:27 id_dsa
-rw-r--r-- 1 davidfallah Domain Users  613 Mar 18 17:27 id_dsa.pub
-rw-r--r-- 1 davidfallah Domain Users 1675 Mar 18 17:26 id_rsa
-rw-r--r-- 1 davidfallah Domain Users  405 Mar 18 17:26 id_rsa.pub
-rw-r--r-- 1 davidfallah Domain Users  512 Mar 18 16:16 known_hosts

根据我所研究过的类似问题，我尝试运行chown -v :Users .ssh/*以防万一，并得到以下结果：

$ chown -v :Users .ssh/*
changed ownership of ‘.ssh/authorized_keys’ from davidfallah:Domain Users to :Users
changed ownership of ‘.ssh/gitolite-admin’ from davidfallah:Domain Users to :Users
changed ownership of ‘.ssh/gitolite-admin.pub’ from davidfallah:Domain Users to :Users
changed ownership of ‘.ssh/id_dsa’ from davidfallah:Domain Users to :Users
changed ownership of ‘.ssh/id_dsa.pub’ from davidfallah:Domain Users to :Users
changed ownership of ‘.ssh/id_rsa’ from davidfallah:Domain Users to :Users
changed ownership of ‘.ssh/id_rsa.pub’ from davidfallah:Domain Users to :Users
changed ownership of ‘.ssh/known_hosts’ from davidfallah:Domain Users to :Users

但是，这个确切的输出每次都会重复，表明它实际上没有做出任何更改。同样，尝试运行chmod -v 777 ssh/*（作为权限配置示例）会持续产生以下输出：

$ chmod -v 777 .ssh/*
mode of ‘.ssh/authorized_keys’ changed from 0644 (rw-r--r--) to 0777 (rwxrwxrwx)
mode of ‘.ssh/gitolite-admin’ changed from 0644 (rw-r--r--) to 0777 (rwxrwxrwx)
mode of ‘.ssh/gitolite-admin.pub’ changed from 0644 (rw-r--r--) to 0777 (rwxrwxrwx)
mode of ‘.ssh/id_dsa’ changed from 0644 (rw-r--r--) to 0777 (rwxrwxrwx)
mode of ‘.ssh/id_dsa.pub’ changed from 0644 (rw-r--r--) to 0777 (rwxrwxrwx)
mode of ‘.ssh/id_rsa’ changed from 0644 (rw-r--r--) to 0777 (rwxrwxrwx)
mode of ‘.ssh/id_rsa.pub’ changed from 0644 (rw-r--r--) to 0777 (rwxrwxrwx)
mode of ‘.ssh/known_hosts’ changed from 0644 (rw-r--r--) to 0777 (rwxrwxrwx)

无论我以普通用户身份还是以管理员身份运行 Cygwin64 终端，此行为都是相同的。

如果相关的话，我的/etc/fstab文件是：

# For a description of the file format, see the Users Guide
# http://cygwin.com/cygwin-ug-net/using.html#mount-table

# This is default anyway:
none /cygdrive cygdrive binary,noacl,posix=0,user 0 0

我还从以下来源获得以下信息df -T：
