network sniffer mac

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

From -- http://blog.csdn.net/zhangnn5/article/details/6810347 Reading this articleArticleBefore that, I suppose you already know the TCP/IP protocol, ARP protocol, What Is sniffer, and other basic network knowledge.In a General Lan, there are usually two access methods, one is hub access (The Hub here refers to the general hub ), one is direct access from a vswitch (the vswitch here is a relatively advanc

the network. On the Tools menu, locate the Address Book option and run, and in the Left tool menu in Address Book, you can find a magnifier icon, which is the "Auto Search" button. After you run the Auto Search feature, enter the start IP address and end address of the network in the IP address segment, and the system automatically searches. When the search is complete, a list of machines appears. 2. Save

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

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

here. The rest can be explained in detail by its help documentation.To run the files required by tcpdump:Tcpdump can run well on UNIX, Linux and Mac OSX operating systems, it is now the latest version of Tcpdump 4.0.0, and we can download its binary package from www.tcpdump.org. At the same time, to run it, you also need to install the Libpcap1.0.0 Driver Library in the system.The version of Tcpdump under the Windows system is windump, and it is also

the hybrid mode, the system core will respond and determine whether these nodes have a sniffer.. This kind of detection method is also limited. There is no way to modify the sniffer of the kernel, but this kind of sniffer is a minority after all.In addition, some dynamic packet capture drivers (Winpcap) in Win2k may also respond to NICs that are not in the hybri

future use. Because Sniffer's address book stores information such as the IP address of the client in the network and the MAC address of the NIC, if the client in the network has changed the NIC, you must re-search the machine list and re-Save the address book. If no new machine is added in the network, you do not nee

Sniffer has always been an annoying hacker tool because it is a static attack software and its existence does not leave any trace, therefore, it is difficult for people to pull it out. However, it is quite harmful (it is like a monitor, and your "every action" is under its surveillance, you say it is not very harmful ). Therefore, it is necessary to find a way to check whether there is sniffer in the

I have always wanted to write an sniffer application tutorial. This item was retained in the CISCO post co-sponsored by J_Lee last time. Today I am free to do this.Sniffer software is just a glimpse of me. Therefore, this tutorial is just a tutorial for beginners. However, if you do not have a certain network foundation, it may still make you feel hard to post it. If you are interested, come and play with m

Internet cafe sniffing With the development of multiple levels and diversity of the Internet, Internet cafes have been used in simple applications such as instant messaging, Web browsing, and email, extended into technical applications that run a large number of online games, online video and audio, interactive teaching, and P2P. Application features also present diversity and complexity. Therefore, these applications impose more stringent and demanding requirements on the quality of our

Sniffer is a technology that uses computer network interfaces to intercept data packets destined for other computers. This technology is widely used in network maintenance and management. It works like a passive sonar, silently receiving various information from the network. Through the analysis of this data, the
