Recently, when learning the NIC driver, we need to capture the situations where the Nic sends and receives data. so we found the tcpdump and wireshark tools, which are used to capture data, wireshark is used to analyze the captured data. the usage is recorded below: Tcpdump usage method (1) first, key words about the type mainly include host, net recently, when learning the NIC driver, you need to capture t
Do application identification this piece is often used to analyze the data traffic generated by the application.Grab the bag using Wireshark, extract features, to the session to filter, find the key stream, here summarizes the basic syntax of wireshark filtering, for their future reference. (The brain can't remember anything)Wireshark filtering can be divided int
Summary: This paper introduces the knowledge of TCP-oriented connection theory, and describes the meanings of each field of TCP message. In this paper, a TCP connection is selected from the Wireshark capture packet to establish the relevant message segment.I. Overview TCP is a reliable connection-oriented transport protocol, two process data before the need to establish a connection, where the connection is only a few allocated in the end system cache

One: The NPF driver isn ' t running
This error is caused by not opening the NPF service.
NPF, the network packet filter (Netgroup Packet FILTER,NPF), is the core part of WinPcap, which is the component of WinPcap to complete the difficult work. It handles packets transmitted over the network and provides a capture, send (injection) and analytical performance (analysis capabilities) to the user level.
It not only provides basic features (such as grasping packages), but also has more advanced f
