First, the purpose of the experiment:Deep understanding of the principle of MAC address flooding attack through actual combat.Second, the experimental principle:There is a very important table in the switch, called the Mac table, which is a hardware-made table, mainly to complete the fast forwarding. Mac tables have si

Let's do an experiment.1. Preparation Tool Win7 MAC Address Changer, RegshotUse Win7 MAC address changer to change MAC addresses before you open Regshot to detect changes in the registry.Create a pre-modified registry snapshotThen open Win7

When the ifconfig eth0 hw ether 11:22:33:44:55:66 is executed, the current kernel shows a successful modification, but the ping only sends ARP packets indefinitely, and the PC has given the board back the ARP packet, but without any ICMP packet information, Suspicion is caused by an illegal MAC address.This is what the online article says:When entering the second sentence the command is prompted: Siocsifhwaddr:cannot assign requested

The MAC address in the IPv4 environment has become a common topic. Here is a summary and sharing. In the TCP/IP architecture, MAC addresses play a very important role. In communication, the host Nic identified by the MAC address serves as the hardware

Recently, a netizen asked a small set of such a question: How to check the notebook MAC address Ah? In response to this issue, the small series below for you to introduce the details. MAC address is also known as the physical address of the network card, each computer has a

Many software applications need to bind MAC addresses (for example, OpenCountry). sometimes we need to modify the MAC address of the NIC for special purposes. 1. Method 1: Use the command to temporarily modify: ifconfigeth0downifconfigeth0hwetherxx: xx: xxifconfigeth0up2. Method 2: as long as the MAC

host USB device devices, and select the identified dongle. Start the migrated virtual machine and install VMware tools.Third, after restarting the A8 service can not start, after the check found that the dongle is bound to the MAC address of the network card, when the migration did not modify the MAC address, resultin

After using Linux 3.9 as the core of the KVM host, you may experience an IGB when you assign the VF (IGBVF) to use the Sr-iov of an Intel NIC (such as: 82576, I350). You can see the following error message in the guest's DMESG: The code is as follows Copy Code IGBVF 0000:00:03.0:IRQ for Msi/msi-xIGBVF 0000:00:03.0:invalid MAC address:00:00:00:00:00:00Igbvf:probe of 0000:00:03.0

First, to obtain a legitimate MAC addressWhen getting the password for the wireless network, the main idea is to use a similar airodump-ng such as monitoring software (WildPackets Omnipeek,kismet), to obtain a legitimate client MAC address, and then change the MAC address of

Disable forwarding of a specific MAC address on a cisco SwitchIt is really annoying to see other illegal DHCP in the LAN. In addition to the dhcp snooping method, you can also directly disable the mac address! The MAC address of m

Details of the Linux neighbor subsystem: confirm-OpenVPN server mode MAC address learning, confirm-openvpnmacIn the article parsing the aging time principle of ARP cache implemented by Linux, I analyzed the conversion of the neighbor subsystem of IPv4 on the Linux protocol stack and again pasted the state machine Conversion Diagram, but this figure is more detailed, because it has an external input, that is

Because the MAC address of the network interface is addressed in the interface card hardware, it is not possible to modify it directly on the hardware. However, you can use the ifconfig command to set a spoofed mac address for the network card , and a variety of Web applications will use this new

Failure background:After cloning virtual machine, even not the Internet, ifconfig view, found that the network card eth0 did not start, so ifconfig eth0 up eth0 network card, the results can not start, enter/etc/sysconfig/network-scripts/ Ifcfg-eth0 view, found that the MAC address and IP address is the same as the original, so modify the IP service network resta
