Wireshark is a grab package software, more easy-to-use, in the usual can use it to grasp the package, analysis protocol or monitoring network, is a better tool, because recently in the study of this, so write a tutorial to facilitate everyone to learn.

). TCP provides high reliability data communication for two hosts. His work involves dividing the data that the application gives to it into appropriate chunks to the network layer below, confirming the packets received, setting the timeout clock for sending the last confirmed packet, and so on. Because the transport layer provides high reliability end-to-end communication, the application layer can ignore all of these details. UDP, on the other hand, provides a very simple service for the appli

The analytic format of Wireshark can be used to understand the protocol flow and the meaning of individual cells. Wireshark Setup Preparation 1, edit-by pre
I. Distributed blocking services (distributed denial of service)
DDoS is a special case of DoS, hackers use multiple machines to attack at the same time to prevent normal users to use the service. After hackers have invaded a large number of hosts beforehand, to install DDoS attack on the victim host to attack the target; some DDoS tools use a multi-level archit
In the network security world, DDoS attacks are not a new term. The earliest DDoS attacks date back to 1996, and in China, DDoS attacks began to occur frequently in 2002, and 2003 has begun to take shape. In recent years, however, this cliché of cyber-attacks has created a huge cyber-security threat with new ways of attacking.

Wireshark is the most popular network analysis tool in the world. This powerful tool captures data from the network and provides users with a variety of information about the network and upper layer protocols. Like many other network tools, Wireshark uses the PCAP network library for packet capture. can crack LAN QQ, mailbox, MSN, account number and so on password !!Wireshark's name was ethereal, and the ne

Preface
Wireshark is an essential tool for network researchers. Since Wireshark2.0, it has fully supported the OpenFlow protocol. Wireshark is also a great boon for those who study SDN, today we will introduce a technique-how to use Wireshark to capture data packe
If you want to build a Wireshark protocol parsing plug-in, you can solve the problem of custom protocol parsing in your work.
Okay, let's talk about it. Start working.
First, check the information on the Internet. To develop a plug-in Environment in Windows, you need:
1. The C/C ++ compiling environment in Windows is required. Well, I have installed vs2008. You can use it.
2. Install cygwin.
Download it at http://www.cygwin.cn. The download is only a
This weekend, it was a headache. The website suddenly couldn't be opened, and it was a tragedy to quickly connect remotely. ssh couldn't be connected, and it always timed out. The first response was ddos attacks.
The result of the connection to the data center is that the traffic is full. What's even more tragic is that there is no hardware firewall in the data center. There is no way to go to the data center and check the IP address, only a few IP ad
Misunderstandings about DDoS attacks
DDoS attacks are on the rise, and experts are also trying to defeat them. Analysts predict that the global DDoS prevention market will grow by 2013 from 2018 to 19.6%. However, many people do not know how the attack works. The misunderstandings about DDoS mainly include the followi
I believe you have heard of DoS attacks, DDoS attacks, and DRDoS attacks! DoS is short for Denial of Service and DDoS is short for Distributed Denial of Service and Distributed Denial of Service. DRDoS is short for Distributed Reflection Denial of Service, this is the meaning of Distributed Denial-of-Service.
However, the most severe attack method in these three cases is
