# 1 服务端 #

(1) 安装pppoe，安装完成后，会有pppoe-server命令

yum install rp-pppoe

安装完成后，会在动在/etc/ppp目录下生成pppoe-server-options文件。

(2) 修改服务配置文件

vi /etc/ppp/pppoe-server-options

# PPP options for the PPPoE server
    # LIC: GPL
    #  认证方式为chap, 还可以配置为pap方式
    # win7密码是加密的，可能不支持pap，所以测试最好是chap
    require-chap
    login
    lcp-echo-interval 10
    lcp-echo-failure 2

(3) 修改配置文件 /etc/ppp/options

vi /etc/ppp/options

# local    # local for chap
    auth       # auth for chap
    lock        # lock for chap

(4) 添加账户

(a) 若采用chap认证方式

vi /etc/ppp/chap-secrets

# Secrets for authentication using CHAP
    # client        server  secret                  IP addresses
    "test"          *       "12345678"                   *

(b) 若采用pap认证方式

vi /etc/ppp/pap-secrets

# Secrets for authentication using PAP
    # client        server  secret                  IP addresses
    "test"          *       "12345678"                   *

(5) 设置支持IP转发

vi /etc/sysctl.conf

net.ipv4.ip_forward = 1　　# 修改为1

(6) 启动pppoe

pppoe-server -I eth0 -L 192.168.11.101 -R 192.168.22.200 -N 10 -F
    # -L 虚拟PPPoE接口，不是eth0的IP地址(可以不设置eth0的IP地址)
    # -R 起始地址
    # -N 地址个数
    # -F 前台运行，默认后台运行

# 2 客户端 #

## 2.1 win7 客户端 ##

(1) 添加pppoe客户端，如果已经存在，则直接连接

(a) 打开网络共享中心

## 2.2 centos 客户端 ##

(1) 安装 rp-pppoe 包

yum install rp-pppoe

(2)使用root用户，执行 pppoe-setup 生成配置

pppoe-setup

# 按照提示输入对应内容即可
    Ethernet Interface: eth0
    User name:          test
    Activate-on-demand: No
    DNS:                Do not adjust
    Firewalling:        NONE
    User Control:       yes
    Accept these settings and adjust configuration files (y/n)? y
    Adjusting /etc/sysconfig/network-scripts/ifcfg-ppp0
    Adjusting /etc/ppp/chap-secrets and /etc/ppp/pap-secrets
      (But first backing it up to /etc/ppp/chap-secrets.bak)
      (But first backing it up to /etc/ppp/pap-secrets.bak)
    
    Congratulations, it should be all set up!
    Type '/sbin/ifup ppp0' to bring up your xDSL link and '/sbin/ifdown ppp0'
    to bring it down.
    Type '/sbin/pppoe-status /etc/sysconfig/network-scripts/ifcfg-ppp0'
    to see the link status.

(3) 运行

[root@centos ~]# ifdown ppp0       // 停止
    [root@centos ~]# ifup ppp0         // 运行
    [root@centos ~]# 
    [root@centos ~]# ifconfig          // 查看网口配置
    ppp0      Link encap:Point-to-Point Protocol  
              inet addr:192.168.22.201  P-t-P:192.168.11.101  Mask:255.255.255.255
              UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1492  Metric:1

              RX bytes:220 (220.0 b)  TX bytes:265 (265.0 b)

(4) 查看日志信息
