Title: Samba configuration management method and system for network device

Description:
The present application is an US national stage application of the international patent application PCT/CN2016/101400 filed on Sep. 30, 2016, which is based upon and claims the priority of Chinese Patent Application No. 201510908147.5 filed on Dec. 9, 2015 and entitled “SAMBA CONFIGURATION MANAGEMENT METHOD AND SYSTEM FOR NETWORK DEVICE”, the entire contents of which are incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to computer technologies, and in particular, to a samba configuration management method and system for a network device. 
     BACKGROUND 
     A router typically provides a Samba service, which may share files stored in the router. A user may set file sharing by modifying the configuration file of Samba. The configuration information includes users who are allowed to access, share directories, read-write permissions and the like. The general practice for setting a share directory is adding information of a share directory into the configuration file of Samba, and the general practice for deleting a share directory is deleting the corresponding information of the share directory from the configuration file of Samba. In practice, since most external storage devices (for example, a U disk, a TF card and the like.) may be frequently inserted or removed. As a result, the share directory path of the Samba configuration file is inconsistent with the actual path thereof, and thus the user fails to access the configuration file. For example, a U disk  1  with a disk letter F is externally connected to a router initially, and if the F disk is shared, the share directory of the configuration file is the F disk; if subsequently the U disk  1  is removed and another U disk  2  is inserted, the disk letter of the U disk  2  is changed to F, and in this case if the U disk  1  is re-inserted, the disk letter of the U disk  1  is changed to G. However, the disk letter of the share directory recorded in the configuration file is still F disk, which causes a lot of invalid configurations in the Samba configuration file. 
     Accordingly, how to find a technical solution to reduce invalid configurations of router Samba configurations has indeed become a problem to be urgently solved by a person skilled in the art. 
     SUMMARY 
     In view of the above defect in the prior art, the present disclosure is intended to provide a Samba configuration management method and system for a network device, to solve the problem in the prior art that invalid configurations are present in the Samba configuration file due to insertion or removal of an external storage device.

Various details in the specification may also be based on different viewpoints and applications, and various modifications or variations may be made without departing from the spirit of the present disclosure. 
     It should be noted that the drawings in the embodiments are merely intended to illustratively explain the basic concept of the present disclosure, and the drawings only illustrate components relevant to the present disclosure and are not drawn according to the quantity of components, the shapes and dimensions thereof in practice. The shape, quantity and scale of the components in practical implementation may be randomly altered, and the deployment of the components may be even more complicated. 
     One embodiment of present disclosure further provides a Samba configuration management method for a network device. Samba is a toolkit, and implements Session Message Block protocol in Unix, which may be also referred to as the NETBIOS/LanManager protocol. Server Messages Block is a communication protocol for sharing files and printers over a local network, and provides services for sharing such resources as files and printers among different computers within the local area network. File sharing may be set by modifying the configuration file of Samba. The configuration information may include users who are allowed to access, share directories, read-write permissions and the like. The general practice for setting a share directory is adding information of the share directory into the configuration file of Samba (smb.conf), and the general practice for deleting a share directory is deleting the corresponding information of the share directory from the configuration file of Samba. In the technical solution, according to the present disclosure, the configuration information is imported to a Samba configuration file after the storage device is reinserted into a router, such that the problem of share failure due to changes of the path of an external device is solved. The network device includes a router. In one embodiment, as illustrated in  FIG. 1 , the Samba configuration management method includes the following steps: Step S 1 : When setting a share directory in a storage device, information of the share directory is added into a configuration file of a Samba server, and the information of the share directory is stored into a share backup file of the storage device, wherein the information of the share directory includes a share path. The information of the share directory refers to relevant information of the share directory, and may include a share path, a share name, users who are allowed to access, read-write permissions and the like. In one embodiment, the share backup file may be stored in a root directory of the storage device. The share backup file is a hidden file. The storage device is an external storage device, including a U disk, a TF card and the like. 
     Step S 2 : When it is detected that the storage device is removed from a network device, the information of the share directory related to the storage device is deleted from the configuration file of the Samba server. The network device includes a router. 
     Step S 3 : When it is detected that the storage device is inserted into the network device, the information of the share directory in the share backup file of the storage device is read piece by piece, and the following operations are performed: acquiring a share path of the information of the share directory, modifying a disk letter of the share path into a current disk letter of the storage device, judging whether the modified share path exists, if the modified share path exists, adding the information of the share directory into the configuration file of the Samba server, and if the modified share path does not exist, deleting the information of the share directory from the share backup file. In one embodiment, the method further includes: when deleting a share directory of the storage device, deleting the information of the share directory from the configuration file of the Samba server, and deleting the information of the share directory from the share backup file of the storage device. In one embodiment, the method further includes: when modifying a share directory of the storage device, modifying the information of the share directory in the configuration file of the Samba server, and modifying the information of the share directory in the share backup file of the storage device. In practice application, steps S 1 , S 2  and S 3  according to the present disclosure may be randomly performed without any sequential restriction as described above. 
     In one embodiment, the network device is a router. A Samba configuration management method for this network device includes: 1. Setting a share directory: When the router shares a file of a network, the configuration file smb.conf of a Samba server may be modified, and share-relevant information (for example, a share path, a share name, users who are allowed to access, read-write permission and the like) is backed up under a root directory of the device, wherein the backup file is a hidden file. When the share file is deleted or modified, the backup file in the root directory is also modified. 2. Inserting or removing an external storage device: A. When a storage device is inserted, the CPU judges whether a backup of the Samba configuration file exists in the storage device, and if the backup exists, the backup information is read, and whether the disk letter in the share path is the current disk letter is judged, if the backup does not exist, the disk letter is modified to the current disk letter, then whether the share path exists is judged, if the share path does not exist, the share information is deleted, and otherwise, the share information is added to the configuration file smb.conf of the Samba server. B. When a storage device is removed, the CPU detects that the storage device is removed, and then clears all share information relevant to the storage device. 
     The embodiment of present disclosure further provides a Samba configuration management system for a network device. The above described Samba configuration management method may be applied in the Samba configuration management system. The network device includes a router. In one embodiment, as illustrated in  FIG. 2 , a Samba configuration management system  1  for a network device includes a share information management module  11 , a device removal management module  12  and a device insertion management module  13 .
