In the penetration test, information collection is particularly important. In the information collection stage, the penetration test team can use various methods to obtain information about the topology and system configuration of the target network. Whether the information is perfect or not will seriously affect the speed and depth of subseque ...

http2 protocol frame format We know that network transmission is in binary form, so the transmission at the bottom of all protocols is also binary. So the problem comes. The client sends a packet to the server. How does the server know whether the packet is completed or still being sent? Or, if a data packet is too large, the client needs to b ...

The book is based on a simple scenario: the user enters a URL into the browser and returns the response, which is the life cycle of a network request. The book is divided into six parts: The application layer client generates HTTP and delegates it to the protocol stack of the operating systemThe protocol stack (TCP/IP module) calls the netwo ...

Socket is the basis of network communication, which is equivalent to establishing a pipeline between the sending end and the receiving end to realize the mutual transmission of data and commands Fundamentals of computer network Network architecture Network protocol A set of rules, standards, or conventions established for the exchange of ...

Section 1 Dubbo dynamically generated classes When dubbo calls the exportServices() method, it will use code generation technology to dynamically generate the subclasses of Protocol$Adaptive, ProxyFactory$Adaptive and Wrapper. Dubbo uses javassist to dynamically generate classes. Dubbo has two scenarios using dynamic classes. 1)ExtensionLo ...

This paper records the receiving and contracting processing of vxlan interface kernel. VXLAN(Virtual Extensible LAN) is a network virtualization technology, a large two-layer tunnel technology, which encapsulates the two-layer package in UDP to build a virtual two-layer network. The configuration and application scenarios of vxlan of equipment ...
