Step s403, managed devices are to web administration client Returning equipment login interface, and parameters such as username and password are imported in prompting.
Step s404, user are by web administration client input username and password information.
Step s405, web administration client send username and password information to managed devices.
The legitimacy of step s406, managed devices verified users identity, and count the no show upper limit and user identity when legal at current login user, the newly-built user's information structure in this locality is preserved all information relevant with user identity.
Step s407, managed devices Returning equipment management homepage face are to the web administration client, and the user starts an idle overtime timer for this reason simultaneously.
Step s408, user be by this equipment of web administration client normal management, simultaneously, and backstage timed sending heartbeat message.The transmission of this heartbeat message is pre-set in web administration client access procedure in advance at interval.
Step s409, managed devices receive after the heartbeat message of web administration client, the idle overtime timer of this user's correspondence of resetting.
Step s410, web administration client browser withdraw from unusually.
This withdraws from unusually and comprises that browser directly cuts out, or because of web administration client device netting twine is pulled out, the web administration client operating system is restarted or the browser that causes that shuts down withdraws from unusually.
Step s411, managed devices do not receive the heartbeat message that the web administration client sends in the default time, the idle overtime timer of this user's correspondence is overtime, deletes local stored user information structure, and current login user number subtracts 1.
Step s412, web administration client are used same username and password login once more by web browser visit managed devices, and information such as username and password are submitted to managed devices.
The legitimacy of step s413, managed devices verified users identity, and count the no show upper limit and user identity when legal at current login user, the newly-built user's information structure in this locality is preserved the information relevant with user identity.
Step s414, managed devices Returning equipment management homepage face are to the web administration client, and the user starts an idle overtime timer for this reason simultaneously.
In the embodiments of the invention two, be respectively the web administration client and managed devices is an example, specify embodiments of the present invention with the Web client and the network equipment.As shown in Figure 5, after the user successfully logined, managed devices detects the web administration client, and whether online flow process comprised:
The username and password that step s501, managed devices send by the web administration client according to the user, the legitimacy of verified users identity, and count the no show upper limit and user identity when legal in the current login user of this user, the newly-built user's information structure in this locality is preserved all information relevant with user identity.
Step s502, managed devices Returning equipment management homepage face are to the web administration client, and the user starts an idle overtime timer for this reason simultaneously.
Step s503, user are by this equipment of web administration client normal management, and managed devices receives the instruction that the user sends.Simultaneously, the backstage timed sending heartbeat message of user place web administration client.The transmission of this heartbeat message is pre-set in web administration client access procedure in advance at interval.
The backstage here be meant operate in client, be built in the Web page but the program that can not show to the user, as be embedded in web authentication and insert script such as Java and ActiveX program in the page of back, these programs are operation automatically in authentication by the back, send heartbeat message according to predefined interval, then out of service when closing client or closing the authentication back page, thus the transmission of termination heartbeat message.
Step s504, managed devices are judged the heartbeat message that whether receives the web administration client within the predetermined time.Then carry out step s505 as if receiving, then do not carry out step s506 if receive.
When the heartbeat message that receives from client, managed devices need be discerned the transmit leg of heartbeat message, promptly judges it is which user has sent heartbeat message.This identification can send the user name of heartbeat message or as the IP address of equipment that the user uses in heartbeat message source or as MAC (Media Access Control, the media interviews are controlled) address of the equipment that the user uses in heartbeat message source etc. by identification.If when existing same user name repeatedly to login, cause to distinguish by IP address or MAC Address by same managed devices, can be by the client background program being set, in heartbeat message, adding by other signs of managed devices distribution and discern, as increase the login time sign, can the same user who repeatedly logins at same managed devices be distinguished.
In this step, the preset time standard can be set as required, can be the transmission cycle of one or several heartbeat message, be 10s, time standard when being two cycles when the heartbeat message transmission cycle for example, and managed devices can be judged the heartbeat message that whether receives the user in 20s.In addition, when networking situation more complicated, also need to consider network delay, can be on one or several cycle of default heartbeat message proper extension time again.
Step s505, managed devices are reset behind the idle overtime timer of this user's correspondence, and the overtime timer that should leave unused once more starts, and changes step s504.
Step s506, managed devices judge that the idle overtime timer of this user's correspondence is overtime, delete local stored user information structure, and current login user number subtracts 1.
The deletion of this user's information structure only relates to the user corresponding with overtime idle overtime timer, when even same user has at a time logined repeatedly simultaneously, only delete and corresponding one of overtime idle overtime timer, what other were not overtime then can not be affected.As previously discussed, cause the overtime reason of this idle overtime timer may comprise following several situation: browser directly cuts out, or because of web administration client device netting twine is pulled out, the web administration client operating system is restarted or the browser that causes that shuts down withdraws from etc. unusually.
In above step, use mechanism that user terminal timed sending heartbeat message, the network equipment detect heartbeat message in real time as the foundation of judging that user terminal is whether online, when this kind mechanism is moved between web administration client and managed devices, because the limited amount of web administration client can not impact the handling property and the operation conditions of managed devices.When being applied to all user terminals, can be provided with according to the actual conditions of equipment, as suitable heartbeat message transmission interval etc. is set, making not to influence the normal operation of the network equipment because of the processing of heartbeat message and timer.
Need to prove that the idle overtime timer of the detection heartbeat message in the embodiment of the invention is different be used to detect the idle the overtime timer whether user operate in the prior art after login, the two finishes different function.As detect the idle the overtime timer whether user operates after login, in the default time as 10 minutes, if do not detect the indication that Any user sends, judge that then this user is overtime and with this user's login compulsory withdrawal, if and the heartbeat message that receives user terminal that in 10 minutes, just is not interrupted, can think that also this user is overtime, with user's login compulsory withdrawal.
By using the whether online method of the described detection user terminal of above embodiment, under the situation that does not influence normal device configuration and service operation, make the network equipment correctly perception Web user whether withdraw from unusually, reach whether really online purpose of supervisory user terminal, thereby improved the ease for use of web administration.
In the embodiments of the invention three, a kind ofly detect the whether online system of user terminal as shown in Figure 6, comprise at least one user terminal 10 and the network equipment 20.
Wherein, heartbeat message transmitting element 11 by the authentication of the network equipment and after successfully logining, regularly sends heartbeat message to the network equipment the user.Wherein, this heartbeat message transmitting element can be the script in the page behind web authentication, as Java and ActiveX program.According to different needs, this heartbeat message may need to carry signs such as user name, IP address, user's MAC address, user's login time, so that the network equipment 20 carries out the identification in heartbeat message source.
The network equipment 20 further comprises timer units 21, reset cell 22, heartbeat message detecting unit 23 and processing unit 24.
Wherein, timer units 21 is after user Web inserts, according to the message initiated timer about this user of processing unit 24 transmissions.When timer time surpasses predefined time, send the message of these user's timer expiries to processing unit 24.In addition, according to the replacement timer instruction that reset cell 22 sends, the timer of designated user is reset.
Heartbeat message detecting unit 23 detects the heartbeat message that user terminals 10 send, and judges the user who sends heartbeat messages according to other information of carrying in the source of message or the message, and sends the message that receives the user terminal heartbeat message to reset cell 22.
Processing unit 24 detects whether to receive user's overtime message that timer units 21 sends, and when the message that receives about certain user's timer expiry, with this user's of this locality storage message structure deletion, and current login user number is subtracted 1.In addition, when receiving the logging request of user terminal transmission, judge whether to allow this user's login, when judged result is logined for permission, set up the user information, send the corresponding Web page to user terminal, and the message that starts to timer units 21 transmission timers.
By the system and the equipment that use as whether the described detection user terminal of above-mentioned embodiment is online, realized the detection that user terminal is online, whether make the network equipment can correctly detect Web user withdraws from unusually, reach whether really online purpose of supervisory user terminal, thereby improved the ease for use of web administration.
