Description

A kind of method that free time time-out applied to O&M auditing system disconnects automatically
Technical field
The present invention relates to O&M audit technique field, is to surpass a kind of free time applied to O&M auditing system specifically The method that Shi Zidong disconnects.
Background technology
In the prior art, abbreviation O&M is safeguarded to computer software and hardware system operation.O&M auditing system be it is a kind of towards One of the system, its most important function of the central controlled O&M security audit pattern of user is central access control.User Access target equipment can be gone by O&M auditing system using equipment account in client, O&M auditing system is then according to user In the connection that the equipment account that client uses is established between client and corresponding target device, so that user can pass through client Target device corresponding to the access of end, therefore, O&M auditing system act as the role of " go-between ", i.e. user passes through client Operation data is forwarded to corresponding target device by O&M auditing system, while the data that target device returns are examined also by O&M Meter systems are transmitted to corresponding client.In this process, O&M auditing system maintains and client and and target simultaneously The connection of equipment.O&M auditing system of the prior art, due to O&M auditing system remain client and target device it Between connection, when operation maintenance personnel occur it is away from keyboard or for a long time do not return and forget to exit when, session does not have Disconnection can operate server by other people, cause unsafe factor, and because operation maintenance personnel is not operated for a long time, and O&M The auditing system moment is keeping in touch, and causes occupancy and the waste of O&M auditing system resource and the resource of target device.
The content of the invention
It is an object of the invention to provide a kind of method that free time time-out applied to O&M auditing system disconnects automatically, use In solving in the prior art, the state that operation maintenance personnel long time no operations and O&M auditing system are still within connection causes resource Occupancy and the problem of waste.
In order to achieve the above object, the present invention is achieved through the following technical solutions:
A kind of method that free time time-out applied to O&M auditing system disconnects automatically, including:
S1) user logs in O&M auditing system;
S2) user sets free time length in O&M auditing system;
S3) O&M auditing system connection client and server, server is accessed by O&M auditing system for user Resource;
S4) the customer flow monitoring module monitors of O&M auditing system flow through the flow of O&M auditing system;
S5) O&M auditing system is judged in setting free time length, if there is flow, if so, connection is then kept, if No, then the connection of client and server is disconnected automatically.
User is that operation maintenance personnel logs in O&M auditing system, set in O&M auditing system allow user and server without The maximum time of data interaction is free time length.O&M auditing system establishes the company of client and server as proxy server Connect, user accesses the resource of server by O&M auditing system.Customer flow monitoring module monitors in O&M auditing system The data of server are flowed to from client and from server flows to the data of client, if monitoring, user and server there are data Interaction, then keep connection.If customer flow monitoring modular does not monitor that the time of data interaction reaches the free time length of setting, O&M auditing system sends and disconnects signal, the automatic connection for disconnecting server and client, after avoiding user's end of operation Forget to disconnect and cause occupying system resources and unnecessary resource overhead, reduce keeper's operation, save human cost And the time, improve operating efficiency.
Preferably, the step S3) in user access server resource mode include graphics protocols access and character association View accesses two ways.
When user logs in O&M auditing system with graphics protocols or character protocols, the data of O&M auditing system are flowed through, Parse, the operation data of user and the heartbeat signal of client and server can be made a distinction via O&M auditing system, The interference of heartbeat signal is excluded, therefore can accurately distinguish the free time of O&M auditing system, in time by free time Connection more than setting duration disconnects.
Preferably, the step S4) in customer flow monitoring module monitors flow through O&M auditing system flow include figure The flow and character protocols of user input data during shape protocol access services device resource access user during server resource The flow of input data and the flow of server output data.
When user logs in O&M auditing system with graphics protocols, the customer flow monitoring module monitors in O&M auditing system To the graphics protocols data of user's input, and as timing node, start timing.If in the free time length of setting, Do not monitor that the graphics protocols data of user's input flow through O&M auditing system, then O&M auditing system sends and disconnects letter Number, client and server are disconnected.After if user logs in O&M auditing system with graphics protocols, customer flow monitoring Module monitors the graphics protocols data of user's input again, then the graphics protocols data last time of user's input is flowed through into fortune The time of dimension auditing system is updated to timing node, restarts timing.If user is to log in O&M audit with character protocols System, the character protocols data for being not only user's input of the customer flow monitoring system monitoring in O&M auditing system, is also wrapped The character protocols data of server output are included, when customer flow monitoring modular is except the user monitored in process of user login The character protocols data of character protocols data and the server output of input, in the free time length of setting, do not monitor word When symbol protocol data flows through O&M auditing system, then cut-off signal is sent by O&M auditing system, client and server are broken Open connection.When the character protocols data that customer flow monitoring module monitors to user input and the character for monitoring server output Protocol data, then segmentum intercalaris when the time that the character protocols data last time exported server flows through O&M auditing system is Point, restarts timing, and when timing time reaches the free time length of user's setting, then O&M auditing system sends and disconnected Signal, client and server are disconnected.
Preferably, the step S5) concretely comprise the following steps:
S5.1) the customer flow monitoring module monitors will supervise to when having user input data or server output data The time that the data last time measured flows through O&M auditing system is sent to the renewal time stamp module of O&M auditing system;
S5.2) renewal time stamp module by the data received last time flow through O&M auditing system when Between as new timestamp, restart timing;
S5.3) the computation-free time module of O&M auditing system calls the timestamp in the renewal time stamp module, And present system time and timestamp are done into subtraction, obtain difference and send the difference to O&M auditing system;
S5.4) O&M auditing system, if difference >=free time length, is transported by the difference compared with the free time length set Tie up auditing system disconnection and the connection of server;If difference < free time lengths, return to step S4).
Customer flow monitoring modular, often monitor that a user input data or server output data flow through O&M audit During system, current system time is recorded, and this time was sent to renewal time and stabs module.Renewal time stamp module receives The time that customer flow monitoring modular is sent, and the time record of last time is covered, therefore only retain in renewal time stamp module There are a time record, i.e., the timing node that current O&M auditing system computation-free starts, i.e. timestamp.O&M auditing system In computation-free time module, current system time and timestamp are done into subtraction, obtained difference is current fortune It is the idle time that auditing system user, which is tieed up, without operation, this difference is compared with the free time length set, if difference >=sky Idle is grown, and O&M auditing system disconnects the connection of client and server automatically, realizes the free time time-out of O&M auditing system certainly The function that dynamic circuit breaker is opened.If difference < free time lengths, monitoring is continued by customer flow monitoring modular and flows through O&M auditing system Data, until monitor user input data or server output data make renewal time stamp action or reach The free time length of setting, the automatic module that disconnects of O&M auditing system disconnect the connection of client and server.
Preferably, the step S2) in user O&M auditing system setting free time length specifically include:
S2.1 the configuration item of O&M auditing system) is opened;
S2.2 " limitation of O&M duration " in configuration item) is chosen, opens the idle automatic Disconnected mode of time-out, and set the free time Duration.
The configuration item of O&M auditing system is opened, chooses " limitation of O&M duration " in configuration item, opens idle time-out certainly Dynamic circuit breaker on-mode, and the free time length of setting is inserted in " free time length exceedes _ _ minute " space after configuration item, represent to use Disconnected automatically when family reaches free time length without the operating time.It is RDP associations when user's login O&M auditing system, and with graphics protocols When view accesses server resource, in user's operating process, O&M auditing system normally connects, when user is without graphics protocols data When the time of input reaches the free time length of setting, even if now monitoring the data of server output, client and server Connection still disconnected automatically by O&M auditing system.When user log in O&M auditing system, and by O&M auditing system with When character protocols are SSH protocol entry servers, in user's operating process, O&M auditing system normally connects.When monitoring not During to user's character protocols data input, server output character protocol data is monitored whether, only as user both NULI character Protocol data inputs, and time of server NULI character protocol data output when reaching the free time length of setting, O&M audit system System disconnects automatically.
