PPP protocol is one of the most widely used protocols in the WAN, which has the advantages of simple, user-authentication capability, and can solve IP assignment. A home dial-up is a communication link between the client and the operator's access server via PPP. At present, broadband access is becoming the trend to replace dial-up Internet, in the rapid development of broadband access technology today,

Often see ppp,pppoe these nouns, at that time also looked at a lot of information, but has not quite understood what this is what, what to use, today calm down, read a bit more information, have some preliminary understanding, record down, later have a new understanding and revise.First, slip,ppp,ethernet are all link-layer protocols.Slip and PPP are point-to-poi

We will see the content of the ppp-on script in many compilation processes. So here we will mainly explain this knowledge. We have mentioned the preparation of kernel PPP in previous articles, and also explained the setting of PPP in Linux. Here we will add the content of the ppp-on script. The specific code is as foll

This article describes in detail how to configure PPP authentication and CHAP authentication, and provides the command line for configuration. You can learn about the configuration process through the instance. When configuring PPP verification, select PAP and CHAP. PAP is the user name and password for the plain text transfer, which is not secure. CHAP uses hash values for verification. Passwords are not t

Protocol change can be understood as a simplified version of PPP, which is helpful for deepening the understanding of PPP.In addition, by observing the shortcomings of the "SLIP" protocol, we can gain a deeper understanding of the clever and targeted design of the PPP protocol.SLIP defects in simple encapsu

performs security operations. Any of the above modes can be used to build a virtual private network (VPN), which is also one of the main uses of IPSec. It should be noted that the above two operation modes differ greatly in terms of security implementation. It encrypts and authenticates IP protocol groups. In computing, point-to-point (PPP) is usually used to establish a direct connection between two nodes. It is mainly used to connect two computers

The two PPP authentication protocols (PAP and CHAP) for vroppp setting networking have just completed a test of Dual-router plug-in to the serial port module today, it is used to gain a deeper understanding of the differences between the two PPP authentication protocols PAP and CHAP. 1. First, build a network environment. There are two routers in total, plug in the serial port module respectively, and conne

PPP, that is, the Point-to-Point Protocol, is the data link layer protocol for point-to-point lines launched by IETF. This protocol is not a proprietary protocol. It can connect devices of different vendors, support multiple protocols, provide optional authentication services, compress data in various ways, support dynamic address negotiation, and support multi-link bundling. 1. PAP: Password Authentication Protocol, full name: Password Authentication

First look at the "SLIP" protocol. Protocol change can be understood as a simplified version of PPP, which is helpful for deepening the understanding of PPP.In addition, by observing the shortcomings of the "SLIP" protocol, we can gain a deeper understanding of the clever and targeted design of the PPP protocol.SLIP defects in simple encapsulation: Because there is no negotiation process, many parameters (s

To ensure the security of the network environment, we need to set up a verification mechanism in the network environment, that is, when a user's device wants to communicate with your device, it must pass your authentication. Today, let's take a look at the WAN protocol PPP authentication. There are two PPP authentication methods. One is PAP authentication. one disadvantage of PAP authentication is that the

There are many topics to explain about the PPP protocol. This protocol is also widely used. Here we will focus on the content of LCP. First, let's take a look at the specific architecture of the ppp protocol. I. Overview 1. It is a layer-2 protocol with the same status as HDLC and RARP. 2. PPP architecture: (1) supports multiple upper-layer protocols, such as
