Today, I will talk to you about how to solve the printer ARP virus in the local area network, many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

To produce a phenomenon:

Three printers can be ordered when testing, when normal business, a large amount of data, three printers are responsible for the category of data need to print at the same time, one printer is abnormal, in the server-side PING processing, shows that one of the three printers can not pass, change the client PING, everything is normal, when you send a print instruction to the abnormal printer at the other client The printer prints normally, along with the backlog of documents to be printed on the server.

The misunderstanding is that it is generally believed that the newly established local area network can not have a virus, and the network wiring is not handled by us, and the network cable is used less, so we will focus on the quality of the network cable and the interference of the environment to the network shield. It is also possible that the MAC address of the printer is duplicated when it leaves the factory (the printer MAC address can be modified so it may be repeated by coincidence).

Detection method:

After we PING the IP of each printer, we look at the MAC address of the PING address just now to detect and determine whether there is a duplicate MAC address. If so, check out the self-check-out order for the corresponding printer to check whether the ID number of the printer is duplicated. If the printer ID number is repeated, it indicates that the repetition of the MAC address is not an ARP fraud, but there is a duplicate conflict when the printer MAC address is set, and the printer MAC address needs to be modified. If the printer's ID number is not duplicated, it can be preliminarily judged that there is ARP spoofing in the local area network.

Solution:

There is a conflict printer when the power is off, and zero the computer ARP. Then connect a printer, detect its ARP address, and record it, then clear the ARP of the computer again, check it for another printer, record its MAC address, and bind the MAC address on the server side that needs to be printed.

After reading the above, do you have any further understanding of how to solve the printer ARP virus in the local area network? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
