The tcpdump command can list the headers of data packets passing through the specified network interface, and can completely intercept the "headers" of data packets transmitted on the network for analysis. It supports filtering for network layer, protocol, host, network or port, and provides logical statements such as and, or, not to help you extract useful information.

Introduction Bro is an open source network analysis framework that focuses on network security monitoring. It is the result of 15 years of research and is widely used by universities, research labs, supercomputing centers and many in the open science community. It was developed primarily by the Berkeley International Computer Science Institute and the National Supercomputer Applications Center at the University of Illinois at Urbana-Champaign. Bro's features include: Bro's scripting language supports site-specific monitoring strategies Support for a high-performance network analyzer supports many protocols and enables advanced semantic analysis at the application level It retains rich application-layer statistics of the networks it monitors Bro is able to Interfaces with other applications to exchange information in real time. Its logs comprehensively record everything and provide a high-level view of network activity.

I just discovered that after turning on static caching with thinkphp, there is a way to use templates from other themes, but it still looks for templates in the original theme, resulting in the template being unable to be found. After the key is static caching, you can access the templates of other themes normally. . How should this be handled?
