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
