Any tool software has a wealth of features, so in the daily maintenance of internet cafes, for a software, not only to know its surface function, but also to understand its working principle, so as to more effectively mining software more advanced applications and functions, in order to solve the network of difficult problems. The following combined with some of the day-to-day
Principles of network sniffing tools sniffer wireshark
Today, I suddenly think of this question: the reason why wireshark can catch packets from other hosts is shared Ethernet. How can I use wireshark for switched Ethernet?
I read some documents online and sorted out the following article.
Sniffer is a common method for collecting useful data. The data can be us
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
Network listening of different transmission media is different. Generally, Ethernet is more likely to be listened on, because Ethernet is a broadcast-type network and FDDI Token is more likely to be listened on, although it is not a broadcast-type network, however, packets with tokens are evenly transmitted over half of the computers on the

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

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.

The main goal of the Sniffer tool is to discover the surviving hosts in the target network based on UDP, because the UDP access process is less expensive.Since many operating systems have a common denominator when dealing with the closure of UDP ports, we are using this commonality to determine if there are surviving hosts on this IP.When we send a packet to a UD
