a Layer 2 Switch Based on the Vlan number, log on to the background management system of the Target layer 2 core switch with a privileged account, and switch the system to the global configuration status, enter the "displaymac" string command at the command line prompt in this status. On the System screen, the result page shown in 3 is displayed, and the conflicting mac address is found, record the port numbers that should be recorded; Once the specific switch port is located, we can find the c

Virus Trojan scan: manual scan of QQ Trojan Horse stealingI. Preface In previous articles "virus Trojan scan and removal 002nd: manually killing pandatv incense", I basically detected and killed the "pandatv incense" virus without using any tools. After all, "pandatv incense" is a relatively simple virus, and it does not adopt some particularly powerful self-prot

Problem Description:Native Windows myeclipse10.7 runs a non-maven Java project, where some classes are injected using SPRING3 annotations, scanned using a configuration file Component-scan, and everything works in the native debug test, But when it hits a jar and puts it on a Linux server, it always says: Org.springframework.beans.factory.NoSuchBeanDefinitionException:No Bean named ' XXXX ' is DefinedCheck the note name, configuration file, file encod

The most effective way to optimize group by IS to use the index directly to get the field that requires the group completely. When using this access method, MySQL uses the type of index that the keyword sorts (for example, the Btree index). This allows the fields in the index to be used for group not to fully cover the key in the Where Condition index. Because it contains only a portion of the keywords in the index, it is called a loose index scan. H

In the Internet era, hackers are a group of mysterious people in our lives. Legend has it that they are arrogant, advocating themselves and acting strangely, stirring the lifeblood of the entire network and making them alive. In reality, however, they live beyond our boundaries. Imagine that in a busy Office, every employee is immersed in his/her own affairs in a narrow workspace; the voice that can be heard is the heartbeat of fingers waving on the keyboard and the one-on-the-other phone rings.

In the network, addresses are the basis of our applications. Address-related attacks often occur. So how can we effectively stop this problem? This should start with the ARP Address Resolution Protocol. This article describes the application and principle of the Protocol. 1. interchanging network sniffing The ARP Address Resolution Protocol does not receive ARP r

I. The background of knowledge1. What is ARPARP, the Address Resolution Protocol, realizes its physical address through an IP address. In a TCP/IP network environment, each host is assigned a 32-bit IP address, which is a logical address that identifies the host in the internetwork. In order for the message to be transmitted on the physical network, the physical address of the destination host must be known. There is an address translation problem that transforms the IP address into a physical a

Defense methods 1. Bind the MAC address and IP address Prevent IP address theft. If you access the Internet through the proxy server: On the proxy server side, ask the network administrator to bind the static IP address of the Internet to the NIC address of the recorded computer. For example: ARP-s 192.16.10.400-EO-4C-6C-08-75. In this way, the static IP address 192.16.10.4 and the computer with the NIC address 00-EO-4C-6C-08-75 are bound together. Ev

What is ARP? ARP stands for AddressResolutionProtocol. In the LAN, the actual transmission is frame, and the frame contains the MAC address of the target host. In an Ethernet network, to directly communicate with another host, you must know the MAC address of the target host. The target MAC address is obtained through the Address Resolution Protocol. The so-called "Address Resolution" refers to the process

ARP operations in Linux 1. Basic Principles Address Resolution Protocol (ARP) is a TCP/IP Protocol for obtaining physical addresses based on IP addresses. When the host sends information, it broadcasts ARP requests containing the target IP address to all hosts on the network and receives the returned messages to determine the physical address of the target; after

How the 1.ARP worksThe core function of IP layer protocol ARP is to obtain the host's hardware address through the destination host IP address, and then communicate through the hardware address. Like many technologies in a computer network, the ARP protocol also uses the idea of building a cache table. It requires each host to maintain an
