Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
the invention is realized by the following technical scheme, as shown in fig. 1-2, a remote desktop access method for an operation and maintenance auditing system, wherein a simulation server establishes a plurality of simulation user terminals which are in one-to-one correspondence with remote terminals, so that a user terminal is connected with the corresponding remote terminals through the simulation user terminals, and the user terminal selects or switches any one of the connected remote terminals to carry out operation and maintenance work;
the invention comprises a user terminal, an operation and maintenance auditing system and a plurality of remote terminals; the operation and maintenance auditing system comprises a terminal control module and an authentication service module connected with the terminal control module, wherein the terminal control module comprises an analog service end and a plurality of analog user ends respectively connected with the analog service end; the user terminal is connected with the simulation server side; the plurality of simulation user sides are respectively connected with the plurality of remote terminals in a one-to-one correspondence manner.
It should be noted that, through the above improvement, the invention provides a remote desktop access method for an operation and maintenance auditing system, when a user terminal needs to access a plurality of remote terminals, the operation and maintenance auditing system provides a simulation service end to establish simulation user ends corresponding to the remote terminals one by one, and the user terminals are respectively connected with the corresponding remote terminals through the simulation user ends.
The user terminal can be connected with a plurality of remote terminals at the same time, but only can carry out operation and maintenance work with one of the remote terminals, so that the user terminal can freely switch the remote terminals needing operation and maintenance among the connected remote terminals.
In the traditional operation and maintenance auditing system, user authentication is required to be carried out every time a remote terminal is accessed, and when a double-factor password is used for logging in the operation and maintenance auditing system, the efficiency of authentication every time is very low. In the invention, a plurality of remote terminals can be logged in only by carrying out authentication and authentication of the user terminal once, thereby improving the efficiency of newly establishing connection for the user.
In a traditional operation and maintenance auditing system, each remote terminal session displays a separate window on a user terminal, the session switching efficiency is low in the case of multiple remote terminal sessions, and the user terminal starts multiple session windows to consume a lot of resources. When the user terminal accesses a plurality of remote terminals, only one session window is displayed on the user terminal, and the user can switch the sessions through the list, so that the resource overhead of the user terminal is reduced, and the operation and maintenance experience of the multi-remote terminal during operation and maintenance is improved.
Other parts of this embodiment are the same as those of the above embodiment, and thus are not described again.
Example 2:
the present embodiment is further optimized based on the above embodiments, as shown in fig. 1 to fig. 2, and specifically includes the following steps:
step F1: the simulation server receives the connection of the user terminal and requests the authentication service module to authenticate the logged user terminal; if the authentication fails, ending the connection session, and if the authentication succeeds, acquiring all remote terminal lists owned by the user in the operation and maintenance auditing system;
step F2: the simulation server returns the remote terminal list owned by the user to the user terminal, the user selects the remote terminal which needs to be connected and needs to be operated and maintained, and the simulation server creates a simulation user side and respectively connects the simulation user side to the remote terminals;
step F3: the simulation server side returns the connected remote terminal list to the user terminal;
step F4: the simulation server monitors an input event of the user terminal and an event of the remote terminal;
step F5: and the simulation service end processes the input event of the user terminal and the event of the remote terminal.
It should be noted that, with the above improvement, the operation and maintenance auditing system provides a simulation server for receiving a request from a user terminal to connect to a remote terminal. When the user terminal requests to connect the remote terminal, the simulation server requests an authentication service module of the operation and maintenance auditing system to perform identity authentication on the user terminal. If the authentication fails, ending the session with the user terminal; and if the authentication is successful, the simulation server side acquires a remote terminal list which is qualified to be connected by the user from the operation and maintenance auditing system.
The simulation service end returns the remote terminal list which can be connected by the user to the user terminal, and the user selects the remote terminal which needs to be connected and operated and maintained through the user terminal. The user can select one or more remote terminals from the remote terminal list to connect, but only can carry out operation and maintenance work with one remote terminal.
After the user selects the remote terminal, the simulation server establishes simulation user ends which are in one-to-one correspondence with the remote terminal, the simulation user ends are connected with the corresponding remote terminal, and the user terminal is connected with the remote terminal through the simulation user ends. And the simulation server monitors the event transmitted between the user terminal and the remote terminal and processes the event.
Other parts of this embodiment are the same as those of the above embodiment, and thus are not described again.
Example 3:
in this embodiment, further optimization is performed on the basis of the above embodiment, as shown in fig. 1 to fig. 2, the step F1 specifically includes the following steps:
step F11: in the operation and maintenance auditing system, a simulation server monitors an RDP (remote desktop protocol) port and waits for a connection request;
step F12: a user initiates a connection request to the operation and maintenance auditing system through a user terminal, and after receiving the request, the simulation server establishes communication connection with the user terminal;
step F13: the method comprises the steps that a screen of a user terminal is divided into a Window area and a List area by an analog server;
step F14: the user inputs the credential for logging in the operation and maintenance auditing system from the user terminal;
step F15: after receiving the login credentials of the user terminal, the simulation service terminal initiates a user authentication request to the authentication service module; if the authentication fails, the simulation server side is disconnected with the user terminal; and if the authentication is successful, the simulation server side acquires all remote terminal lists owned by the user in the operation and maintenance auditing system.
It should be noted that, through the above improvement, in the operation and maintenance auditing system, the simulation server monitors the RDP protocol port and waits for the connection of the user terminal. When a user initiates connection with a remote terminal to the operation and maintenance auditing system through a user terminal, the simulation server establishes communication with the user terminal after receiving a request of the user terminal. The simulation server divides a screen of the user terminal into two areas, namely a Window area and a List area.
The user inputs the credential of logging in the operation and maintenance auditing system from the user terminal, and after the simulated service end receives the login credential of the user terminal, the simulated service end initiates a user authentication request to the authentication service module to verify whether the identity of the user is valid. If the authentication fails, disconnecting the session with the user terminal; and if the authentication is successful, the simulation server side acquires a remote terminal list which can be connected by the user from the operation and maintenance auditing system.
Other parts of this embodiment are the same as those of the above embodiment, and thus are not described again.
Example 4:
in this embodiment, further optimization is performed on the basis of the above embodiment, as shown in fig. 1 to fig. 2, the step F2 specifically includes the following steps:
step F21: the simulation server side returns a remote terminal list owned by the user in the operation and maintenance auditing system to a Window area of the user terminal, and the user selects the remote terminal needing to be connected and operated and maintained;
step F22: the simulation server side obtains the remote terminal selected by the user and establishes simulation user sides respectively corresponding to the remote terminal;
step F23: the simulation user sides are respectively connected with the corresponding remote terminals;
step F24: the simulation server sets a connection state value of the simulation user side and a corresponding remote terminal; the method specifically comprises the following steps:
the simulation server sets a remote terminal connection state value connected with the user terminal as inactive; and the simulation server sets the connection state value of the remote terminal for operation and maintenance with the user terminal as active.
It should be noted that, through the above improvement, the simulation server returns the acquired remote terminal list to the Window area of the user terminal, and the user selects a remote terminal that needs to be connected and operated. The simulation server establishes simulation user ends which are in one-to-one correspondence with the remote terminals according to the selection of the user, and the simulation user ends are connected with the corresponding remote terminals.
Because the user terminal intelligently operates and maintains with a remote terminal, when the remote terminal is only in connection with the user terminal, the simulation server sets the connection state value of the remote terminal and the corresponding simulation user terminal as inactive; when the remote terminal and the user terminal are in operation and maintenance relationship, the simulation server sets the connection state value of the remote terminal and the corresponding simulation user terminal as active.
Other parts of this embodiment are the same as those of the above embodiment, and thus are not described again.
Example 5:
in this embodiment, further optimization is performed on the basis of the above embodiment, as shown in fig. 1 to fig. 2, the step F3 specifically includes the following steps:
step F31: after the connection between the simulation user side and the remote terminal is successfully established, the simulation user side requests the remote terminal to perform image rendering on the resolution of a Window area of the user terminal;
step F32: the simulation server side returns the remote terminal List with the established connection to the List area of the user terminal; the remote terminal list comprises the IP, the login account and the connection state value of the remote terminal connected with the user terminal.
It should be noted that, through the above improvement, after the analog user end is connected to the corresponding remote terminal, the analog user end requests the remote terminal to perform image rendering on the resolution of the Window area of the user terminal, so that when the remote terminal is accessed later, data is actually displayed on the Window area of the user terminal.
The simulation server side returns the remote terminal List with the established connection to the List area of the user terminal, and the returned remote terminal List of the user terminal comprises information such as IP, login account and connection state value of the remote terminal. The user can select to connect or switch the remote terminal needing operation and maintenance by clicking the remote terminal List in the List area.
Other parts of this embodiment are the same as those of the above embodiment, and thus are not described again.
Example 6:
in this embodiment, further optimization is performed on the basis of the above embodiment, as shown in fig. 1 to fig. 2, the step F4 specifically refers to:
the input event of the user terminal comprises a user terminal registration newly-built connection event and a connection switching event;
the simulation server monitors protocol data forwarding and operation and maintenance work performed by the user terminal and the remote terminal;
when the simulation server receives the data of the user terminal, the operation and maintenance auditing system calls a sending interface of the simulation user terminal to send the data to a remote terminal corresponding to the simulation user terminal;
when the simulation user side receives the data of the remote terminal, the operation and maintenance auditing system calls a sending interface of the simulation service side to return the received data to the user terminal;
the newly-built connection event is a new remote terminal which needs to be connected and is selected by the user terminal;
the connection switching event is that the user terminal switches the remote terminal needing operation and maintenance in the connected remote terminals.
It should be noted that, through the above improvement, after the current remote terminal is successfully connected to the user terminal, the simulation service end monitors the data transmission event between the user terminal and the remote terminal. The monitored events comprise input time of the user terminal and events of the remote terminal, and the input events of the user terminal comprise new connection events and connection switching time for registering the user terminal.
When the connection state value of the remote terminal is active and the simulation server receives the data of the user terminal, the operation and maintenance auditing system calls a sending interface of the simulation user terminal to send the data to the remote terminal corresponding to the simulation user terminal; and when the simulation user side receives the data of the remote terminal, the operation and maintenance auditing system calls a sending interface of the simulation service side to return the received data to the user terminal.
When the connection state value of the remote terminal is inactive, the simulation user side sends a request of the supress Output to the remote terminal to tell the remote terminal to stop data return, and at the moment, the simulation user side also stops processing data coming and going between the remote terminal and the user terminal when the connection state value of the remote terminal is inactive.
In the process that the user terminal accesses the remote terminal, the user can establish a new remote terminal connection, and in the operation and maintenance process, the operation and maintenance remote terminal can be switched at any time. Therefore, when the simulation server needs to monitor whether a new remote terminal needs to be connected with the user terminal; similarly, the simulation server also needs to monitor whether the user terminal needs to switch the remote terminal for operation and maintenance.
Other parts of this embodiment are the same as those of the above embodiment, and thus are not described again.
Example 7:
in this embodiment, further optimization is performed on the basis of the above embodiment, as shown in fig. 1 to fig. 2, the step F5 specifically includes the following steps:
step F51: the simulation server side checks the input event of the user terminal and checks whether a new connection event exists; if yes, go to step F21; if not, the next step is carried out;
step F52: the simulation server side checks the input event of the user terminal and checks whether a connection switching event exists; if yes, the remote terminal connection state value of the operation and maintenance before switching is set as inactive, the connection switching configuration is synchronized to the user terminal, then the remote terminal connection state value after switching is set as active, and the step F4 is skipped; if not, the next step is carried out;
step F53: the simulation server side checks the connection state value of each remote terminal connected with the user terminal and checks whether the connection is disconnected; if yes, logging off the connection state value of the disconnected remote terminal, and carrying out the next step; if not, go to step F4;
step F54: the simulation server side checks whether a remote terminal with a inactive connection state value exists; if yes, selecting a remote terminal with the closest time to operate and maintain with the user terminal, setting the connection state value of the remote terminal to active, and jumping to step F4; if not, the operation and maintenance work is finished.
It should be noted that, through the above improvement, the simulation server not only needs to monitor the data protocol transmission between the ue and the remote terminal, but also needs to monitor whether the ue has an update input event. The process of checking the user terminal input event by the simulation server side comprises the following steps:
firstly, checking whether a new connection event exists, if so, jumping to step F21, and adding the newly established remote terminal into a List of a List area of the user terminal; if not, the simulation service end checks whether a connection switching event exists.
If a connection switching event exists, setting the connection state value of the operation and maintenance remote terminal before switching as inactive, synchronizing the connection switching configuration to the user terminal, setting the connection state value of the remote terminal to be switched as active, and then jumping to the step F4 to perform operation and maintenance work; if not, the simulation service end checks the connection state value of each remote terminal.
If the remote terminal with disconnected connection is detected, the connection state value of the remote terminal is cancelled, and whether the remote terminal with the connection state value of inactive exists is continuously detected; if not, go to step F4 to continue the operation and maintenance work.
If the remote terminal with the connection state value of inactive is detected, selecting one remote terminal with the nearest event to carry out operation and maintenance work with the user terminal, setting the connection state value of the remote terminal to active, and then jumping to step F4 to continue the operation and maintenance work; if not, the operation and maintenance work is finished.
Other parts of this embodiment are the same as those of the above embodiment, and thus are not described again.
