Anonymous users2024-02-11It is inevitable to be attacked by some people in the local area network, maybe they want to occupy network resources (hehe, grab bandwidth to surf the Internet), or they may be out of curiosity to try new software, in short, this brings a lot of trouble to our normal network use.
Generally, attackers will use software such as "Cyber Law Enforcement Officer" to send packets to change the MAC address corresponding to the gateway IP address in the ARP cache, so that the real gateway cannot be found and cannot be connected to the Internet. Originally, the solution to this attack was to modify the MAC address of the attacker, so that the attacker temporarily lost the real target, and then reconnected to the network to obtain the correct MAC address of the gateway, so that the network could be restored after being attacked in the future.
The method is as follows: go to the virtual DOS mode to ping your gateway, and then use the arp -a command to see the MAC address corresponding to the gateway in the cache, and then record it. When you are attacked again and you cannot access the Internet, you can manually establish a mapping relationship in the form of ARP -s gateway IP and gateway MAC address in DOS to restore communication with the gateway.
However, this method is very troublesome in the case of malicious continuous attacks, and the rigging affects normal use, because you have to modify your cache frequently. Fortunately, I found the anti arp sniffer small thing out of colorsoft,It's very simple to use,Directly fill in the correct MAC of the gateway you recorded,Fill in your own network card MAC,Then turn on automatic protection and protection address conflicts,He will automatically filter out the deception packets of the attack,So that your network is more stable。 Hehe, I'm no longer afraid of the game being disconnected due to attacks.
Now Anti Arp Sniffer is out of the version,But it still doesn't feel convenient enough.,Can't automatically get the current local network card MAC.,Keep popping up the attack prompt when being attacked continuously.,It's very eye-catching.。 But overall it's good.

Anonymous users2024-02-10ARP is really annoying, and so are our unit's.
It took me a long time to figure it out.
Just install this software.
I looked at it and guarded against tens of thousands of depressions.

Anonymous users2024-02-09The ARP protocol is in a local area network, and the actual transmission in the network is a "frame", and the MAC address of the target host is in the frame.
If the host receives an ARP request for an IP address and it is already in the receiver's cache, it updates the corresponding content in the cache with the sender's hardware address (such as the Ethernet address) in the ARP request.

Anonymous users2024-02-08ARP protocol is an abbreviation for "Address Resolution Protocol". In a LAN, the actual transmission of the DAO in the network is the version.
frame", the MAC address of the target host is in the frame. In Ethernet, in order for a host to communicate directly with another host, it is necessary to know the MAC address of the target host. But how is this target MAC address obtained?
It is obtained through the address resolution protocol. Address resolution is the process by which the host converts the destination IP address into the destination MAC address before sending a frame. The basic function of the ARP protocol is to query the MAC address of the target device through the IP address of the target device to ensure smooth communication.

Anonymous users2024-02-07The following is for reference: BAI
arp(address
resolution
protocol).
It is the network address specified back by the physical address of the computer and the temporary DAO in the projection. When it starts, it asks to select a protocol (network layer) address, and checks if this address is already used by another computer, if not, this node is used this address, if this ARP protocol what does it mean?
Defects in the ARP protocol.
The ARP protocol is based on trusting all nodes in a local area network, and it is efficient, but it is not secure. It is a stateless protocol that does not check whether it has sent a request packet, and does not care (in fact) whether it is a legitimate reply, as long as it receives the target MAC is its ARP >>>More
It's not an ARP virus, it's unlikely that ARP is in diskless Internet cafes, and it's not the phenomenon you're talking about. Slow startup could be something else.
ARP attack is to achieve ARP spoofing by forging IP addresses and MAC addresses, which can generate a large amount of ARP traffic in the network to block the network, and the attacker can change the IP-MAC entry in the ARP cache of the target host as long as the attacker continuously sends out forged ARP response packets, causing network interruption or man-in-the-middle attacks. >>>More
