####### 訪問網絡文件系統 #######
###############################
Linux中有兩種主要協議可用來訪問網絡文件系統：NFS和CIFS
NFS(Network File System)可看作是Linux、UNIX及其它類似操作系統的標準文件系統
CIFS(Comon Internet File System)則是針對Microsoft Windows系統的標準網絡文件系統
####################cifs網絡文件系統訪問####################
####################
在windows 7下開啓文件共享：
創建一個文件夾
右健點擊“屬性”，點擊“共享”選項卡，點擊“共享”
下拉列表選擇“Everyone”，點擊“添加”，選擇“讀/寫”權限，點擊“共享”，等待，點擊“完成”
使用win+r調出運行窗口，輸入“\\ip地址”測試
注意：
到這裏還沒有完，因爲windows 7默認不啓用“Guest”帳戶，並且默認拒絕匿名用戶的訪問，所以還需要以下操作
1.打開“控制面板”，點擊“添加或刪除用戶賬戶”，點擊“Guest”帳戶，點擊“啓用”
2.使用win+r調出運行窗口，輸入“gpedit.msc”，打開本地組策略編輯器。依次選擇“計算機配置-->Windows設置-->安全設置-->本地策略-->用戶權限分配”，雙擊“拒絕從網絡訪問這臺計算機”，刪除裏面的“Guest”帳號，點擊“確定”。

默認情況下，使用mount掛載共享
在不使用共享時也會處於掛載狀態，浪費共享服務器的資源
autofs可以實現當使用時自動掛載，當閒置時自動卸載
2.安裝服務

--------------------------------------------------
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

[root@server pub]# man 5 vsftpd.conf
--------------------------------------------------
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
--------------------------------------------------

anon_other_write_enable
If set to YES, anonymous users will be permitted to perform
write operations other than upload and create directory, such as
deletion and renaming. This is generally not recommended but
included for completeness.
Default: NO
