In terms of configuration, PPPoE always has many advantages. The following describes the configuration of PPPOE server and Cisco PPPOE. First, create a broadband connection named libin password libin on your computer and configure it on ATM1. Configure on R1 first, pppoe Client R1 (config) # vpdn enable VPDN R1

Python implements PPPoE attack tool

Objectiveyou may not be familiar with PPPoE, but you are certainly familiar with dial-up access, which is the kind of communication protocol used for dial-up. General PPPoE authentication Internet is mainly used in campus network or cell Network, dial-up interface as shown. But PPPoE is a communication protocol that has some security flaws. Here's a look at three

Simplified PPPOE protocol Concept

The structure of the Internet is very complex. We often see the following PPPOE protocol-related options in the network optimization settings of some system optimization software. So many people are stuck with this agreement. What are the roles and functions of this agreement? Background of PPPOE Protocol With the continuous development of broadband network technology, the application of several mainstream

PPPOE protocol entry-level

The dial-up era seems to be far away. With the intervention of broadband, all households can access the Internet. Here, we will introduce the broadband access technology of the PPPOE protocol. Let's see what's special about this technology. Background of PPPOE Protocol With the continuous development of broadband network technology, the application of several mainstream broadband access technologies, such a

"Image processing" ISP image sensor camera principle

TVs, It is necessary to improve the received image resolution to match the physical resolution of the LCD screen, in order to display the video image on the terminal, therefore, the quality of the Scaler performance will directly determine the display image.Image scaling can be understood as the resampling process of image, the key is to use continuous model function to fit the original discrete image, after the continuous model parameters are obtained, the continuous image is resampled accordi

this: when the machine is started, will u8expstep = 255, s16exptolerance = 50, this is because the image appears faster, if the setting is small, the image will be from dark to light about 5 seconds (here to see personal needs). When the machine executes to about 5 seconds, we then set the value to U8expstep = 16, S16exptolerance =10,u8expstep is set to 16 because preventing changes in the light source will cause the image to quickly effect (flash flash). The s16exptolerance set to 10 is set fo

Understanding the PPPoE protocol discovery phase

Here we will analyze some specific content of the PPPoE protocol. We have also studied the PPP protocol before, so we can understand PPPoE more easily. This time we will also talk about the PPPoE discovery stage. Data packets of the PPPoE protocol are encapsulated in the data domain of the Ethernet frame. Ethernet fram

Design principles in Architecture Interface Separation principle (ISP)-Java Development Technology-experience the beauty of design patterns and algorithms in architecture

Interface Separation principle The core idea of the interface separation principle is that client programs should not be forced to rely on methods that they do not need to use. The English abbreviation ISP, namely interface segregation Principle. In fact, the interface separation principle means: an interface does not need to provide too much behavior, an interface should only provide an external function, should not be all operations are encapsula
