Wireshark-Network packet analysis software
The function of the network packet analysis software is to retrieve the network packet and display the most detailed network packet information as far as possible. Wireshark uses WinPcap as an interface to exchange data messages directly with the network card.
Network administrator uses Wireshark to detect
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

After comparison, it was found that the data packets of two switches before and after the firewall were obviously problematic: there was a very obvious case of packet chaos, the

1. Grab BagCapture extracts the package from the network adapter and saves it to the hard disk.Access to the underlying network adapter requires elevated privileges, so the ability to grab packets from the underlying NIC is encapsulated in Dumpcap, the only program in Wireshark that requires privileged execution, and the rest of the code (including parsers, user interfaces, and so on) requires only normal user rights.To hide all underlying machine dep

TCP relative sequence numbers TCP Window Scaling
By default Wireshark and tshark will keep track of all TCP sessions and convert all sequence numbers (SEQ numbers) and acknowledge numbers (ACK numbers) into relative numbers. this means that instead of displaying the real/absolute seq and ACK numbers in the display, Wireshark will display a seq and ACK number relative to the first seen segment for that con
For application recognition, data traffic generated by applications is often analyzed.
Wireshark is used to capture packets. When extracting features, session filtering is required to find the key stream. The basic syntax of Wireshark filtering is summarized here for your reference. (My mind cannot remember anything)
