篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Linux PPPOE 服务搭建测试相关的知识，希望对你有一定的参考价值。
最近服务器那边需要搭建一套PPPOE拨号上网，网上找了好几次都感觉不能使用，我在基础上做了修改，可以使用了，作为资料共享给大家，共同学习。

PPPOE服务器
与传统的接入方式相比，PPPoE具有较高的性能价格比，它在包括小区组网建设等一系列应用中被广泛采用，目前流行的宽带接入方式ADSL 就使用了PPPoE协议。
1. 系统部署基础
服务器的ip规划
机器 | IP2 | 网关 | 系统 | 作用 |
PPPOE server | 192.168.10.109 192.168.5.109 |
192.168.5.1 | Linux Centos 6.8 x64 | PPPOE 服务端 |
PPPOE Client | 192.168.10.90 | Xp sp3 x86 | PPPOE客户端 |
1.1 服务端搭建
查看是否安装所需要的包。
[[email protected] ppp]# rpm -qa |grep rp-pppoe rp-pppoe-3.10-16.el6.x86_64
配置文件目录在/etc/ppp下
[[email protected] ppp]# cp chap-secrets chap-secrets.ori [[email protected] ppp]# cp pppoe-server-options pppoe-server-options.ori [[email protected] ppp]# ll total 64 -rw------- 1 root root 189 Jan 16 19:09 chap-secrets -rw------- 1 root root 78 Jan 16 18:33 chap-secrets.ori -rwxr-xr-x. 1 root root 2276 May 11 2016 firewall-masq -rwxr-xr-x. 1 root root 978 May 11 2016 firewall-standalone -rwxr-xr-x. 1 root root 386 Apr 12 2016 ip-down -rwxr-xr-x. 1 root root 3262 Apr 12 2016 ip-down.ipv6to4 -rwxr-xr-x. 1 root root 430 Apr 12 2016 ip-up -rwxr-xr-x. 1 root root 6517 Apr 12 2016 ip-up.ipv6to4 -rwxr-xr-x. 1 root root 1687 Apr 12 2016 ipv6-down -rwxr-xr-x. 1 root root 3196 Apr 12 2016 ipv6-up -rw-r--r--. 1 root root 5 Mar 16 2015 options -rw-------. 1 root root 77 Mar 16 2015 pap-secrets drwxr-xr-x. 2 root root 4096 Jul 13 2016 peers -rw-r--r-- 1 root root 140 Jan 16 18:33 pppoe-server-options -rw-r--r-- 1 root root 104 Jan 16 18:32 pppoe-server-options.ori
chap-secrets.ori和pppoe-server-options.ori 是我手动备份的文件，主要修改这两个配置文件
修改配置文件
配置文件pppoe-server-options修改如下：
# PPP options for the PPPoE server
# LIC: GPL
#require-pap
require-chap #验证方式,如果选pap的话，就到pap-secrets文件中增加用户。
login
lcp-echo-interval 10
lcp-echo-failure 2
ms-dns 202.106.0.20
ms-dns 8.8.8.8
具体操作如下
[[email protected] ppp]# cat pppoe-server-options # PPP options for the PPPoE server # LIC: GPL require-chap login lcp-echo-interval 10 lcp-echo-failure 2 ms-dns 202.106.0.20 ms-dns 8.8.8.8
添加用户，设置账户和密码
[[email protected] ppp]# cat chap-secrets # Secrets for authentication using CHAP # clientserversecretIP addresses cmz * cmz * cmz2 * cmz2 192.168.10.3 #可以指定客户端的地址也可以不指定
开启内核ip转发
[[email protected] ppp]# sed -i "s#net.ipv4.ip_forward = 0#net.ipv4.ip_forward = 1#g" /etc/sysctl.conf [[email protected] ppp]# sysctl -p net.ipv4.ip_forward = 1
防火墙设置，设置局域网内机器共享上网
[[email protected] ppp]# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE [[email protected] ppp]# iptables -t nat -nL Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- 0.0.0.0/0 0.0.0.0/0 Chain OUTPUT (policy ACCEPT) target prot opt source destination
解释
# 1. eth0为出口的网卡，就是可以和外网连通的那块。到现在这个pppoe服务器就可以工作了。
# 2. 这不做，就会产生，拨号成功，但是上不了。
启动pppoe服务
[[email protected] ppp]# pppoe-server -I eth1 -L 192.168.10.109 192.168.10.2 -N 20
I：指定响应PPPOE请求的端口，现在使用的eth1，也就是内网的
L：PPPOE服务器的IP地址，客户端连接可以看到的服务器地址
R：这是分配给客户端的地址池起始地址，本例中从192.168.10.2开始
N：地址池的IP地址递增几个，本例中添增10，也就是从192.168.10.2开始分配，一共分配20个IP地址
设置来及启动开机启动

1.2 客户端Windows测试
客户端拨号流程
1. 拨号之前检查
2. 拨号
在XP系统中选择宽带连接，输入正确的账号和密码，之前服务端已经设置好了，账号和密码都是cmz。
选择客户端拨号登录
此时说明拨号已经ok了，检查是否能上网。
3. 拨号之后检查
拨号成功后检后检查客户端是否能正常上网。
以下是dos命令行，详细测试过程： 没有拨号之前操作 Microsoft Windows XP [版本 5.1.2600] (C) 版权所有 1985-2001 Microsoft Corp.

建立PPPoE连接：
[[email protected] ~]# adsl-setup # < 建立ADSL连接我的是第二次重新配置 Welcome to the PPPoE client setup. First, I will run some checks on your system to make sure the PPPoE client is installed properly... The following DSL config was found on your system: Device: Name: ppp0 DSLppp0 Please enter the device if you want to configure the present DSL config (default ppp0) or enter ‘n‘ if you want to create a new one: n LOGIN NAME Enter your Login Name: cmz #输入ADSL连接的用户名 INTERFACE Enter the Ethernet interface connected to the PPPoE modem For Solaris, this is likely to be something like /dev/hme0. For Linux, it will be ethX, where ‘X‘ is a number. (default eth0): #指定网络设备 Do you want the link to come up on demand, or stay up continuously? If you want it to come up on demand, enter the idle time in seconds after which the link should be dropped. If you want the link to stay up permanently, enter ‘no‘ (two letters, lower-case.)

Note that these rules are very basic. You are strongly encouraged to use a more sophisticated firewall setup; however, these will provide basic security. If you are running any servers on your machine, you must choose ‘NONE‘ and set up firewalling yourself. Otherwise, the firewall rules will deny access to all standard servers like Web, e-mail, ftp, etc. If you are using SSH, the rules will block outgoing SSH connections which allocate a privileged source port. The firewall choices are: 0 - NONE: This script will not set any firewall rules. You are responsible for ensuring the security of your machine. You are STRONGLY recommended to use some kind of firewall rules. 1 - STANDALONE: Appropriate for a basic stand-alone web-surfing workstation 2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway for a LAN Choose a type of firewall (0-2): 0 #输入0，不在这里设置防火墙 Start this connection at boot time Do you want to start this connection at boot time?
