Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the following description, suffixes such as "module", "part", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no peculiar meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
The first embodiment.
As shown in fig. 1, an embodiment of the present invention provides a method for accessing a USB storage device under a cloud desktop, where the method is mainly based on a terminal side, and includes the following steps:
step S110: and actively loading the inserted USB storage equipment, mounting the USB storage equipment under a terminal shared directory, and simultaneously acquiring and sending the shared directory parameters of the USB storage equipment to the remote virtual machine.
Specifically, as shown in fig. 2, a natdistkredirect (Nat) program is added on the local terminal side, and when the program runs, the following operations may be performed: first, a shared services subroutine S is initiated for remote directory access. And secondly, actively mounting the mount into the USB storage device of the terminal, and simultaneously acquiring the mount directory name of the device (as a remote shared directory path), the accessed user name and password information and the IP address information of the terminal, and storing the information into a Nat program cache. And thirdly, after the USB storage device is detected to be inserted, an agent service client terminal program TC and two monitoring threads (including a link connection monitoring thread and a data transmission monitoring thread) are created. And fourthly, sending the shared directory information stored in the cache, the user name, the password and other information to the remote virtual machine through the TC.
Wherein, for the agent service client terminal program TC, when it runs, the following operations can be executed: firstly, two TCP connection links are created, one is communicated with a local terminal side sharing service subprogram S, and the other is communicated with a proxy service subprogram PS in the remote virtual machine. Two forwarding threads are created, and are respectively responsible for data forwarding in one direction at the same time, for example, the content received from the socket building the link with the PS is sent out through the socket building the link with the S. Similarly, the content received from S is sent out through the socket which establishes a link with PS, and data conversion is completed.
For two monitoring threads, the link connection monitoring thread is used for detecting the connection status and state of the two TCP connection links, and is responsible for reconnection and connection closing when the link has an error and for closing the link connection when data transmission is finished. The data transmission monitoring thread is used for detecting whether errors occur in sending and receiving in the data transmission process, is responsible for closing transmission when the transmission errors occur, and informs a Nat program to reestablish link retransmission and statistics of the size of transmission data and average data when the transmission is successful.
As shown in fig. 3, when this step is executed, the specific process includes:
step S111: and acquiring a global type code of the inserting equipment, if the inserting equipment is a USB storage equipment, mounting the inserting equipment to a terminal shared directory, and acquiring shared directory parameters of the inserting equipment and storing the shared directory parameters into a cache.
Step S112: and carrying out socket communication with the remote virtual machine, and sending the shared directory parameters of the inserting equipment stored in the cache to the remote virtual machine through the socket communication.
Specifically, the shared directory parameter includes a remote shared directory path of the device, accessed user name and password information, and IP address information of the terminal. And the local terminal side detects the inserted equipment and acquires the equipment type global title, if the equipment belongs to the USB storage equipment, the terminal Nat program stores the USB storage equipment mount to an X directory of a terminal file system, stores the X directory, an access user name, a password and an IP address into a Nat program cache and sends the X directory, the access user name, the password and the IP address to the virtual machine through the TC.
Step S120: and receiving the remote virtual machine to call a system function according to the shared directory parameter to access the USB storage device in the terminal shared directory.
Specifically, as shown in fig. 2, a disk access program V is deployed in the remote virtual machine, and when it runs, the following operations may be performed: firstly, when the disk access program V is started, a proxy service subprogram PS is created for forwarding data between the disk access program V and the shared service subprogram S. And secondly, a network card filtering subprogram F is created and is used for filtering the data packet related to the disk access. And thirdly, a thread is created to establish a TCP connection with a specific port of the PS. And fourthly, calling a system function according to the shared directory information, the user name, the password, the terminal IP and other parameters received from the terminal to access the shared directory of the terminal.
For the agent service subprogram PS, when it runs, the following operations may be performed: first, the connection of two ports, which are respectively the port a connected with the terminal side TC and the port B connected with the remote virtual machine side V, is monitored. Two forwarding threads are created, and are respectively responsible for data forwarding in one direction at the same time, for example, contents received from a socket connected with the TC are sent out through a socket connected with the V. Similarly, the content received from V is sent out through the socket connected with TC to complete data conversion.
For the network card filtering subroutine F, when it runs, the following operations may be performed: network packets of a particular type are filtered to pass only packets associated with the shared directory of the access terminal.
Therefore, as shown in fig. 4, the process of the remote virtual machine calling the system function according to the shared directory parameter to access the USB storage device under the terminal shared directory specifically includes:
step S121: and the remote virtual machine obtains the network packet containing the shared directory parameters through network packet filtering.
Step S122: the remote virtual machine accesses the USB storage device under the terminal shared directory by analyzing the shared directory parameters and calling system functions.
Specifically, the remote virtual machine acquires data sent by the terminal side through data interchange of the PS, and filters a specific type of network packet through the F, so that only a packet related to the shared directory of the access terminal passes through, that is, a network packet including parameters of the shared directory is acquired. Finally, the USB storage device of the terminal is accessed by calling the system function through the V, at the moment, the data transmission process starts, and the user experience is not different from that of using the USB storage device locally on the PC.
In this way, after the terminal is inserted into the USB storage device each time, the Nat program sends the updated shared directory name, the accessed user name, the password, and the terminal IP to the proxy service subprogram PS of the remote virtual machine through the proxy service client subprogram TC, and then the updated shared directory name, the accessed user name, the password, and the terminal IP are forwarded by the PS to the disk access program V of the remote virtual machine. Therefore, the V can call a system function to access the shared directory corresponding to the USB storage device of the terminal, and therefore a process that the cloud desktop (namely the remote virtual machine) quickly accesses the storage device of the terminal is started. At this time, the cloud desktop issues a setting policy according to the server, and can perform access control, such as read-write, read-only, and the like, on the USB storage device. If the access authority of the USB storage device on the local terminal side needs to be changed, the server1 where the remote virtual machine is located sends a command to the Nat program on the local terminal side, and the Nat program changes the configuration file of the sharing service subprogram S by calling the command and restarts the S program.
Example two
As shown in fig. 5, a second embodiment of the present invention provides a method for accessing a USB storage device under a cloud desktop, which is based on a remote virtual machine side and includes the following steps:
step S210: and after the receiving terminal mounts the inserted USB storage equipment to the terminal shared directory, acquiring and sending the shared directory parameters of the USB storage equipment.
Specifically, as shown in fig. 2, a natdistkredirect (Nat) program is added on the local terminal side, and when the program runs, the following operations may be performed: first, a shared services subroutine S is initiated for remote directory access. And secondly, actively mounting the mount into the USB storage device of the terminal, and simultaneously acquiring the mount directory name of the device (as a remote shared directory path), the accessed user name and password information and the IP address information of the terminal, and storing the information into a Nat program cache. And thirdly, after the USB storage device is detected to be inserted, an agent service client terminal program TC and two monitoring threads (including a link connection monitoring thread and a data transmission monitoring thread) are created. And fourthly, sending the shared directory information stored in the cache, the user name, the password and other information to the remote virtual machine through the TC.
Wherein, for the agent service client terminal program TC, when it runs, the following operations can be executed: firstly, two TCP connection links are created, one is communicated with a local terminal side sharing service subprogram S, and the other is communicated with a proxy service subprogram PS in the remote virtual machine. Two forwarding threads are created, and are respectively responsible for data forwarding in one direction at the same time, for example, the content received from the socket building the link with the PS is sent out through the socket building the link with the S. Similarly, the content received from S is sent out through the socket which establishes a link with PS, and data conversion is completed.
For two monitoring threads, the link connection monitoring thread is used for detecting the connection status and state of the two TCP connection links, and is responsible for reconnection and connection closing when the link has an error and for closing the link connection when data transmission is finished. The data transmission monitoring thread is used for detecting whether errors occur in sending and receiving in the data transmission process, is responsible for closing transmission when the transmission errors occur, and informs a Nat program to reestablish link retransmission and statistics of the size of transmission data and average data when the transmission is successful.
As shown in fig. 6, after the terminal mounts the inserted USB storage device to the terminal shared directory, the process of acquiring and sending the shared directory parameter of the USB storage device specifically includes:
step S211: the terminal obtains the global type code of the inserting device, if the inserting device is a USB storage device, the inserting device is mounted under the terminal sharing directory, and meanwhile the sharing directory parameter of the inserting device is obtained and stored in the cache.
Step S212: and the terminal and the remote virtual machine carry out socket communication, and the shared directory parameters of the inserting equipment stored in the cache are sent to the remote virtual machine through the socket communication.
Specifically, the shared directory parameter includes a remote shared directory path of the device, accessed user name and password information, and IP address information of the terminal. And the local terminal side detects the inserted equipment and acquires the equipment type global title, if the equipment belongs to the USB storage equipment, the terminal Nat program stores the USB storage equipment mount to an X directory of a terminal file system, stores the X directory, an access user name, a password and an IP address into a Nat program cache and sends the X directory, the access user name, the password and the IP address to the virtual machine through the TC.
Step S220: and calling a system function according to the shared directory parameter to access the USB storage device under the terminal shared directory.
Specifically, as shown in fig. 2, a disk access program V is deployed in the remote virtual machine, and when it runs, the following operations may be performed: firstly, when the disk access program V is started, a proxy service subprogram PS is created for forwarding data between the disk access program V and the shared service subprogram S. And secondly, a network card filtering subprogram F is created and is used for filtering the data packet related to the disk access. And thirdly, a thread is created to establish a TCP connection with a specific port of the PS. And fourthly, calling a system function according to the shared directory information, the user name, the password, the terminal IP and other parameters received from the terminal to access the shared directory of the terminal.
For the agent service subprogram PS, when it runs, the following operations may be performed: first, the connection of two ports, which are respectively the port a connected with the terminal side TC and the port B connected with the remote virtual machine side V, is monitored. Two forwarding threads are created, and are respectively responsible for data forwarding in one direction at the same time, for example, contents received from a socket connected with the TC are sent out through a socket connected with the V. Similarly, the content received from V is sent out through the socket connected with TC to complete data conversion.
For the network card filtering subroutine F, when it runs, the following operations may be performed: network packets of a particular type are filtered to pass only packets associated with the shared directory of the access terminal.
As shown in fig. 7, the execution process of this step specifically includes:
step S221: and obtaining the network packet containing the shared directory parameter through network packet filtering.
Step S222: and analyzing the shared directory parameters, and calling a system function to access the USB storage equipment under the terminal shared directory.
Specifically, the remote virtual machine acquires data sent by the terminal side through data interchange of the PS, and filters a specific type of network packet through the F, so that only a packet related to the shared directory of the access terminal passes through, that is, a network packet including parameters of the shared directory is acquired. Finally, the USB storage device of the terminal is accessed by calling the system function through the V, at the moment, the data transmission process starts, and the user experience is not different from that of using the USB storage device locally on the PC.
In this way, after the terminal is inserted into the USB storage device each time, the Nat program sends the updated shared directory name, the accessed user name, the password, and the terminal IP to the proxy service subprogram PS of the remote virtual machine through the proxy service client subprogram TC, and then the updated shared directory name, the accessed user name, the password, and the terminal IP are forwarded by the PS to the disk access program V of the remote virtual machine. Therefore, the V can call a system function to access the shared directory corresponding to the USB storage device of the terminal, and therefore a process that the cloud desktop (namely the remote virtual machine) quickly accesses the storage device of the terminal is started. At this time, the cloud desktop issues a setting policy according to the server, and can perform access control, such as read-write, read-only, and the like, on the USB storage device. If the access authority of the USB storage device on the local terminal side needs to be changed, the server1 where the remote virtual machine is located sends a command to the Nat program on the local terminal side, and the Nat program changes the configuration file of the sharing service subprogram S by calling the command and restarts the S program.
