When it comes to ARP attacks, the author first came into contact with it after entering the university. At that time, due to the limited campus network resources of the school, the school allocated bandwidth according to the rooms in the dormitory area. The bandwidth of 512 is sometimes used by more than 10 people, and the speed of the network can be imagined. It is also because of this bandwidth that some students who are familiar with the computer use the "high-tech" means to send ARP broadcast attacks to seize the limited IP address to access the Internet. At the time, the author was once a victim. However, in the campus life that has long followed the ARP attack, it can be said that it is quite worthwhile.
In a blink of an eye, Windows 8 has officially come to people. Win8 is good, but in dealing with ARP network attacks, so far there is no ARP firewall software that is perfectly compatible with Win8. So here, the author recalls that in the past, in the university period, by binding the computer MAC address, the MAC address of the fixed system itself is consistent with the address assigned by the router to avoid possible ARP attacks. Let's share it with you.
Broadband network port reconnection
In fact, in daily life, many netizens have reflected that some shared Internet access if the router does not allocate bandwidth, then when people are more than one will make you crazy Especially in rented houses where people are sharing. When playing online games, the speed of the network is slow, and the network reflects that your game has already been soaked. Looking at the old movie buffer, it’s boring! Some people can’t help but use the P2P Terminator, limit other people’s speed, and break other people’s nets. This is unscientific and not kind. I don’t recommend it here.
In the past, the ARP firewall that supports Win8 is not yet available. ** Digital and ** Butler's own ARP firewall does not support Win8 64-bit version. 32-bit is unclear, so you can only manually bind ARP. .
■CMD Manual Setup Tutorial
Command Prompt (CMD) is the "MS-DOS Mode" under OS/2, Windows CE and Windows NT platform-based operating systems. The main function of CMD is to help computer advanced users to use the command line operation to make advanced adjustments to the computer. The solution provided by CMD, the result is very simple (“ simple and rude).
First, run the command prompt (CMD) with administrator privileges.
Run CMD with administrator privileges. 2. Run "ldsh;netsh i i show in" at the command prompt; check the idx number of the NIC to be ARP-bound.
Enter the specified code
Three, run in the command prompt <;netsh -c “i i” add neighbors idx IP MAC” ARP binding, here idx is found in the previous step The idx number of the NIC, IP and MAC are the IP address and MAC address you want to bind.
The red box is marked with the IP and MAC address that the user needs to fill in.
For example: netsh -c “i i” add neighbors 12 192.168.1.1 D0-27-88-C9-7C -A4
Fourth, at the command prompt, use the “arp -a” command to see if the ARP entry you added is in the list and is static.
“arp -a” Command detection is static
Unbind: netsh -c “i i” delete neighbors IDX (IDX is changed to the corresponding number) to delete the MAC address binding, Then restart the system.
■“.bat”File Creation Tutorial
“.bat” The format file is Batch, also known as batch script. The second technique for manually binding ARP is to use a file in the format of “.bat”, which is a faster and more straightforward way to create a batch format file than the first one.
As the name suggests, batch processing is the processing of an object in batches. The batch file has the extension bat. Currently more common batch processing consists of two categories: DOS batch and PS batch. The PS batch is based on the powerful photo editing software Photoshop, which is used to batch process images. The DOS batch is based on DOS commands and is used to automatically execute DOS commands in batches to implement specific operations.
Notepad fills in the specified content
Save as .ar format as arp binding file name file
1arp -a View MAC address table
arp -s router address MAC address
Example: arp -s 192.168.1.1 D0-27-88-C9-7C-A4
2 Unbind: arp -d Router address MAC address
Contact arp binding note In this edit mode
Example: arp -d 192.168.1.1 D0-27-88-C9-7C-A4
The well-made arp binding and unbinding two quick start files
Then create a new notepad, put the command inside, and save it as bat format, arp binds .bat. When running, right-click to run as an administrator, or drop it into the boot project.
We know that the .bat format batch file can be executed quickly after double-clicking, so we have two batch files that we have created, as shown in the above figure, you can quickly open it after double-clicking, the program is instant. Execute, implement the binding and decommissioning functions of ARP. Very convenient and easy to use.
