####### 访问网络文件系统 #######
###############################
Linux中有两种主要协议可用来访问网络文件系统：NFS和CIFS
NFS(Network File System)可看作是Linux、UNIX及其它类似操作系统的标准文件系统
CIFS(Comon Internet File System)则是针对Microsoft Windows系统的标准网络文件系统
####################cifs网络文件系统访问####################
####################
在windows 7下开启文件共享：
创建一个文件夹
右健点击“属性”，点击“共享”选项卡，点击“共享”
下拉列表选择“Everyone”，点击“添加”，选择“读/写”权限，点击“共享”，等待，点击“完成”
使用win+r调出运行窗口，输入“\\ip地址”测试
注意：
到这里还没有完，因为windows 7默认不启用“Guest”帐户，并且默认拒绝匿名用户的访问，所以还需要以下操作
1.打开“控制面板”，点击“添加或删除用户账户”，点击“Guest”帐户，点击“启用”
2.使用win+r调出运行窗口，输入“gpedit.msc”，打开本地组策略编辑器。依次选择“计算机配置-->Windows设置-->安全设置-->本地策略-->用户权限分配”，双击“拒绝从网络访问这台计算机”，删除里面的“Guest”帐号，点击“确定”。

默认情况下，使用mount挂载共享
在不使用共享时也会处于挂载状态，浪费共享服务器的资源
autofs可以实现当使用时自动挂载，当闲置时自动卸载
2.安装服务

anon_world_readable_only
When enabled, anonymous users will only be allowed to download
files which are world readable. This is recognising that the ftp
user may own files, especially in the presence of uploads.
Default: YES

--------------------------------------------------
anon_mkdir_write_enable
If set to YES, anonymous users will be permitted to create new
directories under certain conditions. For this to work, the
option write_enable must be activated, and the anonymous ftp
user must have write permission on the parent directory.
Default: NO

deletion and renaming. This is generally not recommended but
included for completeness.
