Pppoe user space implementation
One Terminal
Terminal Introduction
A terminal is a type of terminal device. It has multiple types and generally uses tty for short. The following figure shows the connection between the computer system and the terminal.
The main function of the Terminal Driver is to transmit data between the program and related devices. Within a Linux kernel, the terminal basically includes two main software parts: Device Drivers and l
RP-pppoe is a solution that integrates the dial-up client and server.: Http://www.roaringpenguin.com/products/pppoe
The pppoe server in RP-pppoe is divided into user mode and kernel mode.In user mode, a pppoe process is created as a new connection service;In kernel mode, you
4.3.2 Working Principle of pppoe ProtocolThe pppoe protocol workflow consists of two phases: discovery and session. The discovery phase is stateless to obtain the Ethernet MAC address of the pppoe end (on the local ADSL device, and create a unique pppoesession_id. After the discovery stage ends, it enters the standard PPP session stage. When a host wants to start
We have explained the basic content of PPPoE. Here we will focus on the implementation of the PPPoE protocol on BAS. PPPoE dial-up software is already very mature in applications (Windows XP self-carried). The following focuses on the implementation of PPPoE in the Access Server BAS.
1.
PPPoE Overview
PPPoEPoint-to-Point Protocol over Ethernet), that is, the Point-to-Point Protocol on Ethernet, which enables a host on the Ethernet to connect to the Internet through a simple access device, and control and manage the connected users.
PPPoE uses Client/Server). It encapsulates PPP packets in Ethernet frames to provide point-to-point connections over Ethernet.
Recently, I tried 2.6.29 and qtopia2.2 on my mini2440 Development Board. Really good. Unfortunately, U-boot is not provided. However, IThe transplanted U-boot can boot a friendly new kernel. The Konqueror browser is integrated in qtopia2.2 to enable mini2440 Internet browsing.But qtopia2.2 does not seem to provide the ADSL dial-up function, so I decided to port it myself to implement ADSL dial-up Internet access.My ADSL cat is a cat with a wireless route provided by China Telecom. It is from Chi
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
I. In general, it can be divided into four points.
1: ARM Linux kernel supports PPP
2: Install ppp-2.4.4 (RP-pppoe requires support from PPP for normal operation ).
3: Install RP-pppoe.
4: download the file generated in step (2) (3) to the target board, and modify it as prompted.
Ii. required packages
RP-pppoe and PPP are required for porting. I use a combination
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?

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.

Recently, I used WCF to develop a project. I won't write more about it here. There are many good articles in the basic knowledge garden!

Well, let's just talk about the issues that I encountered during development. These two problems have been solved for several days. This article describes the security of my project.

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
Today, we will mainly explain how to set up a PPPOE server. As we all know, the development of networks is amazing. With the continuous evolution, both corporate and home access have entered a new era, the two most common access methods are ADSL Access and FTTx + LAN access. ADSL is an asymmetric digital user line, it is a type of virtual dialing through a common telephone line and adsl modem to a remote ISP's PPP

For one reason or another, I needed to setup a PPPoE Server on my Ubuntu machine. unfortunately almost all the guides found were talking about setting a PPPoE client connected to a PPPoE Server. so I spend a few days t
