Phenomenon of the failure
Local area network (LAN) is directly to visit Internet's by the 2M optical-fibre channel of renting local telecommunication department, all working station in the local area network (LAN) all is connected in one 48 mouthfuls the switch, switch directly links to each other with the broadband router of a TP-LINK model again, has enabled firewall functionality, dhcp server functionality and static address group function etc. in this router.Also has a server of preserving significant data information in the local area network (LAN); in order to protect the safety of server; the Norton fire compartment wall has also specially been installed by unit in server; this fire compartment wall has been configured to the server mode of operation, and all working station in the local area network (LAN) can both normally have access to the important information in the server at ordinary times.
When opening the display screen of server computer, see the miscue that has occurred IP address conflict on the system screen unexpectedly, see this prompting, work station has used one and the afoul IP of server address certainly; The TCP/IP attribute of opening this work station is provided with window, and redistributed another one IP address for this work station, think that changing the IP address function can solve the fault that this work station can't access server, when connecting, find that server still can't visit when conducting interviews again.So open network neighbor's window of this work station, attempt by this window access other work stations in the local area network (LAN) once, found that the fail operation station can successfully visit other work stations in the local area network (LAN), wilfully just can not access server.
Summary of the invention
The object of the present invention is to provide a kind of IP address collision failure brought up by router software BUG solution, mainly solve above-mentioned technical problem described in the prior art, avoid producing IP address conflict to influence the smooth use of network system.
For addressing the above problem, the present invention is achieved in that
A kind of IP address collision failure brought up by router software BUG solution is characterized in that step is as follows:
At first, login into server system with system manager's identity, the mode of operation with fire compartment wall is modified as general mode from server mode then, and some filtering rules in the fire compartment wall are readjusted, and has restarted server system afterwards;
Whether after treating that server system restarts successfully, in the back-stage management interface of switch, carried out the Ping order, normally testing this time, Ping leads to server;
At last, enabled the DHCP service function in the router again, come then by the fail operation station, the TCP/IP attribute that enters into work station is provided with window, open the IP address setting page, choose automatic acquisition IP address option wherein, click confirming button again, this work station is the Dynamic Host Configuration Protocol server application IP address in router still; Behind the setting operation above finishing, reattempt the server access operation.
Described IP address collision failure brought up by router software BUG solution is characterized in that the accident analysis step is:
Whether carry out the Ping order earlier in the fail operation station, it is normal to observe network line;
Then, open the device manager window in the fail operation station, therefrom find the target network card apparatus, and click the icon of this equipment, from the shortcut menu that ejects, carry out the order of stopping using, carry out the order of enabling in this shortcut menu afterwards again with right mouse button;
The back-stage management interface of broadband router is entered in login again, and Dynamic Host Configuration Protocol server is wherein temporarily stopped using, and keeps the backstage parameter of router then and has restarted this router;
The last IP address of a static state of having distributed for the fail operation station again.
Embodiment
The invention provides a kind of IP address collision failure brought up by router software BUG solution, its step is as follows:
One, accident analysis
In order whether there to be line fault between test failure work station and the server, in the fail operation station, carry out the Ping order earlier, the result sees that server can't be arrived by normal Ping, in server system, carried out a Ping order again afterwards, but find normally Ping logical fail operation station of server specifically, clearly to be connected with circuit between this fail operation station be normal to server.Then, open the device manager window in the fail operation station, therefrom find the target network card apparatus, and click the icon of this equipment with right mouse button, from the shortcut menu that ejects, carry out the order of stopping using, carry out the order of enabling in this shortcut menu afterwards again, in the network card equipment start-up course, the IP address of seeing this work station dynamically obtains, and at this moment expects having enabled in the broadband router DHCP service function.The back-stage management interface of broadband router is entered in login again, Dynamic Host Configuration Protocol server is wherein temporarily stopped using, keep the backstage parameter of router then and restarted this router, the last IP address of a static state of having distributed for the fail operation station again, but a series of like this operation does not still bring any effect, and colleague's work station still still can not be visited LAN server.Arrived here, entered into the back-stage management interface of broadband router, wherein static address group and MAC Address record have all been deleted, restart broadband router again, but the result who obtains at last still can't access server.
Two, fault solves
Through top test operation, assert that all working station in the local area network (LAN) all can't lead to server by Ping, that probably is that fire compartment wall in the server has been forbidden the Ping Test function, so login into server system with system manager's identity, mode of operation with fire compartment wall is modified as general mode from server mode then, and some filtering rules in the fire compartment wall have been readjusted, restarted server system afterwards.After treating that server system restarts successfully, in the back-stage management interface of switch, carried out the Ping order, test this whether normally logical server of ping, normally Ping is logical to found that current server, and when attempting other work stations Ping server from local area network (LAN), find that also server can lead to by normal Ping now.At last, enabled the DHCP service function in the router again, come then by the fail operation station, the TCP/IP attribute that enters into work station is provided with window, open the IP address setting page, choose automatic acquisition IP address option wherein, click confirming button again, so this work station Dynamic Host Configuration Protocol server application IP address in router still; Behind the setting operation above finishing, attempted the server access operation again, so far the fault that can't visit of server has just successfully been solved.
Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
