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

For application recognition, the data traffic generated is often used for analysis.
Packet Capture uses Wireshark to filter sessions and find the key stream when extracting features. The basic syntax of Wireshark filtering is summarized here for future testing. (My mind cannot remember anything)
Wireshark can be divided into protocol filtering and content filter

Debugging some of the content of the network, always avoid the need to catch the package, tcpdump is a very suitable tool, this tool can be installed on the server, all the content you need to grasp down, but after the capture it? We also need a tool that can read this package, which is the Wireshark to be introduced.Wireshark is an open source tool, and powerful, easy to use, but under the Mac must have X11 to run, directly installed DMG is not able
To make a long story short, Wireshark has a follow TCP stream feature, which is handy. The drawback is that the extracted stream data does not have time stamps and other information, in the analysis of data delay and packet loss is somewhat inadequate. In this case, a simple follow TCP stream function is implemented with Python, while the TCP information is preserved.The principle is simple and is still based on W
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
