remembers the Mac of a port by receiving data from this port and remembering its source Mac, like a machine's IP corresponding to the MAC's ARP list, the switch maintains a physical port with a Mac table, so the switch can be spoofed. Can send a package to set the source Mac is the Mac you want to receive the machine, then the switch will put your machine's netw

table of a Mac-to-port in its own machine. This table exists when the switch is started. The MAC address of the corresponding port is recorded during the first data transfer on each port. by sending fake mac address data packets to the vswitch, The vswitch can be spoofed to refresh its MAC address to the port data tab

Abandoned for one months, picked up again, rusty a lot. Found in the article "4.1 under" did not mention the Pcap library, it is not supposed to.In the Network data Analysis tool, Tcpdump is definitely the famous, tcpdump bottom is Libpcap library, written by C language. The Pcapy module is a libpcap-based Python interface. Pcapy's project address on GitHub is: Https://github.com/CoreSecurity/pcapy.Let's take a look at how to implement a packet capture using Pcapy.#!/usr/bin/pythonimport pcapyde

packets and NTNetBios name service broadcast. (Etherfind will only identify these packets as broadcast packets of Type 0000 .) This tool runs on MS Windows. It can even monitor network statistics and session information by MAC address (or host name. You can simply click a session to get the output of the tcpdump standard. You only need to click the host to be monitored in a dialog box. Free Software sniffer 1 Sniffit is developed by Lawrence Berkeley

network. After the datagram arrives at the hub, the hub forwards the datagram to the port of each hub. In other words, each network node connected to the hub has the right to receive all data packets. after Sniffer is run, Sniffer sets the NIC to the hybrid mode. Once it is set to the hybrid mode, Sniffer can accept a

all the packets and frames on the network, if a machine is configured in this way, it (including its software) is a sniffer. When a vswitch is usedUnder normal circumstances, data packets from other hosts will not appear on the local network interface, so data packets from other hosts cannot be sniffed. Of course, some special methods can be used for sniffing. 4. Sniffer Principle After introducing the pre

Network, system management, or security technicians always encounter one or more problems during network management and maintenance. For example, why does the network transmission performance suddenly decrease? Why can't I open the webpage, but QQ can be launched? Why are some hosts suddenly disconnected? Such network problems need to be solved quickly and effectively, so as to minimize the impact of network problems on normal business of enterprises. Therefore, we need a tool to help us quickly

○ Collation This article was written one year ago and was not completed for some reason. Today, I sorted out shadowstar's home and accidentally found this unfinished article. Although it was a year ago, it is still not out of date and should be helpful to anyone who wants to know sniffer. My father said that everything should start and end. Today is the Dragon Boat Festival. I would like to send a message to my loved ones who are far away from each ot

can see the Chinese menu of the sniffer software, the following are some commonly used tool buttons. In the day-to-day maintenance of the network, the use of these tool buttons can solve the problem. 1, Host list button: After saving the machine list, click this button, sniffer will display the information of all the machines in the network, in which, the HW address column is the client information in the

captured to pass through. 2. Sniffer defense Although it is very difficult to find a Sniffer, we still have a way to defend against Sniffer sniffing attacks. Since Sniffer wants to capture our confidential information, we just want it to capture it, but we need to encrypt it in advance. Even if hackers have captured o
