This article mainly introduces what software winpcap refers to. It is very detailed and has a certain reference value. Friends who are interested must read it!

Winpcap is a free, public network access system under the windows platform; the purpose of developing winpcap is to provide win32 applications with the ability to access the underlying network, which is used for direct network programming under the windows system.

Winpcap (windows packet capture) is a free, public network access system under the windows platform. The purpose of the project to develop winpcap is to provide win32 applications with the ability to access the underlying network. It is used for direct network programming under windows system.

Characteristics

Winpcap provides a powerful programming interface, it is easy to port between operating systems, but also convenient for programmers to develop.

What kind of programs need to use Winpcap

Many different tools and software use Winpcap for network analysis, troubleshooting, network security monitoring, and so on. Winpcap is particularly suitable for the following classic areas:

1. Network and protocol analysis

2. Network monitoring

3. Communication log recording

4 、 traffic generators

5. User-level bridges and routes

6. Network intrusion Detection system (NIDS)

7. Network scanning

8. Security tools

There are some aspects that Winpcap can't do. It does not rely on host protocols such as TCP/IP to send and receive packets. This means that it cannot block and process communication data between programs on the same host. It can only "sniff" packets on the physical line. Therefore, it does not apply to traffic shapers,QoS scheduling and personal firewalls.

Winpcap internal structure

Winpcap is a system for packet capture and analysis under the Win32 platform. Includes a kernel-level packet filter, an underlying DLL (packet.dll), and an advanced system-independent DLL (Wpcap.dll)
