Specific embodiment
According in conjunction with attached drawing to the described in detail below of disclosure exemplary embodiment, other aspects, the advantage of the disclosure
Those skilled in the art will become obvious with prominent features.
In the disclosure, term " includes " and " containing " and its derivative mean including rather than limit；Term "or" is packet
Containing property, mean and/or.
In the present specification, following various embodiments for describing disclosure principle only illustrate, should not be with any
Mode is construed to limitation scope of disclosure.Referring to attached drawing the comprehensive understanding described below that is used to help by claim and its equivalent
The exemplary embodiment for the disclosure that object limits.Described below includes a variety of details to help to understand, but these details are answered
Think to be only exemplary.Therefore, it will be appreciated by those of ordinary skill in the art that without departing substantially from the scope of the present disclosure and spirit
In the case where, embodiment described herein can be made various changes and modifications.In addition, for clarity and brevity,
The description of known function and structure is omitted.In addition, running through attached drawing, same reference numbers are used for identity function and operation.
Fig. 1 diagrammatically illustrates the flow chart of the remote assistance method of the terminal provided according to the embodiment of the present disclosure.Such as Fig. 1
Shown, this method includes following operation.
S1, first terminal send SSH and request to server.
Server is proxy server, allows second terminal (i.e. control terminal) by the proxy server to first terminal
(i.e. controlled terminal) carries out remote assistance.
First terminal is provided with a switch, and after the user using first terminal clicks the switch, first terminal sends SSH
Request is to server, so that controlled end subscriber can be easy to operate with direct request remote assistance.
First terminal generates RSA key pair, which includes RSA public key, generates SSH according to the RSA public key and asks
It asks, and server will be sent to comprising the SSH of RSA public key request.
RSA Algorithm is a kind of rivest, shamir, adelman, and RSA key is generated to based on RSA Algorithm, is divided into key and public key two
Part.
SSH is the safety shell protocol established on the basis of application layer.SSH in the present embodiment is provided based on key
Safety verification.
S2, after server receives SSH request, the mode and first terminal logged in based on SSH certificate establishes connection, and obtains
Take the facility information of first terminal.
SSH certificate logs in the safety certification based on key that SSH is provided in i.e. the present embodiment, and server supports openssh
After certificate verification, after configuration generates certificate, wait first terminal by the way that server and first can be established after certificate verification eventually
Connection between end.
Specifically, operation S2 includes following sub-operation:
S21 after server receives the request of the SSH containing RSA public key, takes out first terminal sequence number from SSH request,
Verify whether first terminal sequence number is legal, if first terminal sequence number is legal, RSA public key is added server
Authorized_keys file, and time-out information is added behind public key character string.
S22, server be first terminal assignment agent port, the embodiment of the present disclosure support simultaneously to more first terminals into
Therefore row remote assistance when the quantity of first terminal is at one or more, distributes an agent side for each first terminal
Mouthful, each first terminal has its corresponding proxy port.
Since server needs while connecting more first terminals, it is attached at this time using multiport, port is avoided to rush
It dashes forward and remote assistance can not be carried out.
S23, first terminal generate dynamic password, generate DSA key pair according to dynamic password, and allow using DSA key
It logs in.
S24, server record the dynamic password of first terminal, execute SSH reverse proxy.In the present embodiment, reverse proxy
Refer to that proxy server receives the connection request of control terminal, connection request is then transmitted to the controlled terminal on internal network, and
The result obtained on controlled terminal is returned into control terminal.
S25, server obtain the facility information of first terminal, wherein can correctly identify that it is opposite by facility information
The first terminal answered.Facility information, such as device hardware HASH value.
After S26, first terminal and server establish connection, before second terminal carries out remote assistance to first terminal,
It need to carry out data transmission between first terminal and server, to complete the link detection between first terminal and server, really
The IP address of first terminal and server is available before remote assistance and port is unoccupied by guarantor.
S3, second terminal telnet server establish connection according to facility information and first terminal, and to first terminal
Carry out remote assistance.
Firstly, second terminal inquires dynamic password and SSH proxy port according to client's sequence number, generated according to dynamic password
DSA private key uses DSA private key telnet server.
If the configuration access port of second terminal in preset address port range, allows second terminal remote login service
Otherwise device refuses second terminal telnet server, i.e. server directly disconnects the connection between second terminal.It is default
Address port range is the port range for allowing to carry out first terminal the terminal of remote assistance.
Then, second terminal equipment identifies the facility information corresponding according to the facility information of each first terminal
One terminal carries out remote assistance to the first terminal by the corresponding proxy port of the first terminal.
In addition, server in the present embodiment, hiding assist, entirely assisting system, cloud proxy server not external
Any information of exposure, improves the safety of agent equipment.
