Package for synchronous serial link (serail point-to-point link)3.1-hdlc/ppp High-level Data link Control HDLC (high-level Data Link controls): is a bit-oriented synchronous data Link layer protocol developed by ISO, developed by the SDLC protocol. HDLC Specifies the encapsulation on a synchronous serial line by using frame characters and checksums, and HDLC is generally not recommended ;HDLC does not support multiprotocol Ip;cisco in order to enable

PPP is one of the most basic protocols in the network. PPP is the main content of this article. First, let's take a look at the basic concepts of the PPP protocol. The Point-to-Point Protocol is a data link layer Protocol designed to transmit data packets between equal units. This link provides full duplex operations and transmits data packets in sequence.

CCNA Study Notes 13-WAN pppWAN is a type of data communication network over the LAN geographic range. Enterprises must purchase services from WAN service providers. However, a LAN is generally classified as a company goods organization that uses a LAN to connect devices across the WAN to a wider range of geographical areas than a LAN. When you select a cross-region wan network, we recommend that you select the same carrier in the two locations to ensure the traffic bandwidth quality. Leased line

There are two programs for using PPP to access Linux: PPPD and chat. Ubuntu comes with pppd and chat, and you can use man to see how it's used.Typical PPP dialing requires several files to be prepared:1. PPPD script.2. Chat script.3. chap-secrets file.4. pap-secrets file.The chat script is a real send and receive script for the AT command, and the chat script mainly consists of timeout,abort and at instruct

Since you have chosen programming as a profession, you are destined to be a lifelong computer companion. But that doesn't mean you have to ignore your health. Everyone knows, the computer to stay for a long time, one is to hurt your eyes, but sedentary, and will lead to personality withdrawn-because you face the whole day is a computer, not a living person. Go outside, leave the computer, and leave the office. If you're not sure if you should do this, look at the following

This article describes how to use a CDMA modem to implement dial-up Internet access in Linux. First, you need to have a preliminary understanding of the PPP protocol. For example, you should at least know what the LCP and NCP are and what the PAP and chap are. Second, you may need to install pppd and chat tools. These two tools are installed by default in the system. If pppd is not installed, download the latest version at http://ppp.samba.org. The pp

1 Overview The PPP protocol (Point-to-Point Protocol) is widely used in dial-up networks and is gradually replacing the slip protocol. PPP data packet format: | Protocol code | load | fill character There are four types of PPP protocol codes: 1 0x0001-0x3fff Network Layer Protocol (IPv4, IPv6, IPX, appletalk)2 0x4001-0x7fff no network layer protocol involved in s

This document describes the configuration of the PPP Protocol's PAP and CHAP authentication on Cisco routers, and the simple commands involved in the configuration are no longer repeated in the comments ...

When you think that all necessary functions are added or made into modules as needed, you can try to run the following command: # Make dev; make clean; make zlmage; If the system finally prompts that the new kernel exists in/usr/src/linux/arch/i386/boot, the kernel is compiled successfully.
