Embodiment 1
[0140] Figure 4 It is a flowchart of a network fault diagnosis method in Embodiment 1 of the present invention, and the method is used in a device whose operating system is a Linux system, such as Figure 4 As shown, the method includes the following steps S401-S419:
[0141] S401: Use the dmesg command to detect whether the network card hardware of the current device is faulty; if so, execute S402; otherwise, execute S403.
[0142] S402: Check whether the network is normal after processing the network card hardware failure; if yes, end the process; otherwise, execute S403.
[0143] S403: Check whether the network port light is on; if yes, execute S405; otherwise, execute S404.
[0144] S404: Detect whether the network is normal after dealing with the fault that the network port light is off; if yes, end the process; otherwise, execute S405.
[0145] S405: Determine whether the IP information can be obtained by executing the command ifconfig; if yes, execute S413; otherwis...

The invention discloses a network fault diagnosis method and a network fault diagnosis device, and belongs to the field of computer networks. The method comprises the steps of detecting whether network adapter hardware is faulty; if the network adapter network is faulty, detecting whether a network is normal after the fault of the network adapter hardware is processed; if the network adapter hardware is not faulty or the network is still abnormal after the fault of the network adapter hardware is processed, checking whether a network port lamp is lighted; if the network port lamp is off, detecting whether the network is normal after the fault that the network port lamp is off is processed; if the network port lamp is lighted or the network is still abnormal after the fault that the network port lamp is off is processed, detecting whether IP information can be achieved; if the IP information cannot be achieved, detecting whether the network is normal after the problem that the IP information cannot be achieved is processed; if the IP information can be achieved or the network is still abnormal after the problem that the IP information cannot be acquired is processed, detecting whether a network layer still has a problem; and if it detects that the network layer has the problem, processing the problem of the network layer. According to the method, fault points of the network can be rapidly diagnosed and automatically repaired.
Description
technical field [0001] The invention relates to the field of computer networks, in particular to a network fault diagnosis method and device. Background technique [0002] With the development of the computer Internet, users use computers to surf the Internet and have become a part of life. However, due to the many hierarchical structures of network servers, it is difficult to quickly solve the network failure when the network fails. network fault diagnosis method. Contents of the invention [0003] The invention provides a network fault diagnosis method and device, which are used for quickly diagnosing network fault points and automatically repairing the diagnosed network faults. [0004] The present invention provides a network fault diagnosis method, comprising: [0005] Detect whether the network card hardware of the current device is faulty; [0006] If it is detected that the network card hardware is faulty, check whether the network is normal after processing th...
