Description

A kind of broadband-based network detecting method

Technical field

The present invention relates to broadband fault automatic measurement technology, more particularly to a kind of broadband-based network detecting method.

Background technology

In the case where internet is commonly used, because the installation of dangerous software causes network settings to change, Or cause the situation of network failure more and more universal because network knowledge shortage carries out irrational setting to computer, repair automatically Therefore the instrument of multiple network is also developed and applies, but these functions and software are mostly the aids of large software, Desired use must install whole software kit, and occupying system resources are too many, while too many useless function is installed, otherwise use Excessively complexity is difficult to use.

With the popularization and the extensive use of PC of network, and form various kinds software installation, home PC goes out existing network Network failure has turned into the common problem of people, and it is not that part holds that network failure is solved for being unfamiliar with the people of computer and network Easy thing.

The content of the invention

In order to solve the problem, the present invention proposes a kind of broadband-based network detecting method.

The present invention makes most simple directly method automatically detect the factor that may cause network failure, uses Function and method are all that the API that system is provided will not relate to any safety problem, are that the simple of detection network failure has The method of effect.

The technical scheme is that：

A kind of broadband-based network detecting method,

Including：

1）Connectivity checks, be detection far-end IP address whether the method that can be reached, realized by function；

2）Network link is detected, with 1）Method detect fixed service end IP address whether UNICOM；

3）Detection proxy server is set, and detects proxy server facilities, closes after acting on behalf of with 2）Method carry out UNICOM Property detection；

4）Detection fire wall is set, and whether detection fire wall is opened, with 2 after closing）Method carry out connectivity detection；

5）Detection network card status, obtain the relevant parameter of network interface card, and detect whether network interface card parameter setting is reasonable.

Further,

Connectivity is checked, is sent to remote target machine using raw socket and take back existing ICMP packages；

Network link is detected, is that distal end fixed server IP can be configured in a configuration file；

Detection proxy server is set, and is that status data is obtained from specified registry key, closes agency and reexamines connection The general character；

Detection fire wall is set, and is the interface function get_FirewallEnabled and put_ for using INetFwPolicy2 to provide FirewallEnabled is checked and is set fire wall；

Detection network card status be from registration table SOFTWARE Microsoft WindowsNT CurrentVersion Network interface card information is obtained in NetworkCards, judges whether network interface card disables with CreateFile functions, DeviceIoControl letters Number obtains network card status and relevant information, and network card adapter information is obtained using GetAdaptersInfo.

The beneficial effects of the invention are as follows

The present invention is capable of detecting when to be set because of agency, and fire wall is set, and IP is set, network caused by DNS settings are incorrect Failure.

Specific embodiment

More detailed elaboration is carried out to present disclosure below：

【Connectivity inspection method:】

ICMP bags are sent by detection main frame, whether detection distance host can be with UNICOM

1. raw socket, the socket connections of ICMP agreements are created according to distance host IP address

2. set up ICMP packages and send and wait returning result (having three tries)

3. then think that distance host can be with UNICOM, otherwise it is assumed that main frame is unreachable if result is returned；

【Network fault detecting method and step】

The first step：Network link is detected

1. basis【Connectivity inspection method】Method detection main frame whether can be with UNICOM;

2., if can be normal with UNICOM, network, terminate；

If cannot UNICOM, carry out【Second step】

Second step：Detection browses agency and sets

By registration table, facilities are acted on behalf of in detection, judge whether agency is set correct

1. registry key is obtained：

HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\

The value of ProxyEnable and ProxyServer under Internet Settings

2. agency is not enabled if ProxyEnable is 0, carried out【Fire wall is detected】；

3. agency is enabled if ProxyEnable is 1, continued；

4. close proxy server and (ProxyEnable is set into 0) is set

5. the connectivity of distance host is detected；

If 6. UNICOM, then it is assumed that be proxy server influence network, otherwise carry out【3rd step】

3rd step：Detection fire wall is set

Stop fire wall with the related API of fire wall, and detect UNICOM's row of network

The INetFwPolicy2 interfaces provided using windows

1. the function get_FirewallEnabled for being provided using INetFwPolicy2 interfaces

Obtain NET_FW_PROFILE2_PRIVATE and NET_FW_PROFILE2_PRIVATE

Network firewall state

It is unrelated with fire wall if 2. fire wall is all not turned on, terminate fire wall detection；

If 3. fire wall has unlatching, the function put_FirewallEnabled provided using INetFwPolicy2 closes anti- Wall with flues；

4. piece connectivity of detection network；

If 5. UNICOM, then it is assumed that be fire wall influence network；

If 6. obstructed, carry out【4th step】；

4th step：Detection network card status

Whether detection network interface card disconnects or disables

1. obtain all network card adapter information using GetAdaptersInfo functions and preserve

2. from registration table HKEY_LOCAL_MACHINE

SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\NetworkCards

Middle acquisition installs network interface card information：

ServiceName：Service name,

Can be with composition file composition file +ServiceName according to service name

3. CreateFile functions are used, and file handle hFile is opened in successor's file description service

4., if returning to file handle mistake, illustrate that the network interface card is disabled

If the file handle for 5. obtaining is effectively, obtains the state of network interface card using DeviceIoControl functions and believe with related Breath：

Network card status (disconnect, connection), MAC Address of Network Card, network interface card type

6. the multiple network interface cards of fruit, show the selection network interface card page

7. network card status are shown, judges whether network interface card is normal；

If 8. network interface card is normal, network card adapter information is found according to ServiceName, and obtain IP address and gateway and DNS

9. whether the IP address and gateway of detection network interface card are effective IP address

If 10. invalid, IP and gateway set mistake；

If 11. effectively, detect gateway whether UNICOM；

If 12. is obstructed, illustrate that gateway sets mistake, carry out DNS detections

13. judge whether two DNS of network interface card are effective IP address；

14. if effective IP address, detects whether to reach, and can reach and then thinks that DNS has no problem if one, Illustrate that DNS is set if it can not all reach problematic, point out modification DNS to set.

The present invention with a kind of simple effective method detection remote service whether UNICOM, step by step by agency service Device, fire wall, network interface card parameter and DNS data carry out automatic detection, with quick locating network fault Producing reason as According to reparation network failure in time.
