Linux设置pppoe拨号上网

我们现在上网好多都是通过pppoe拨号上网，在windows下我们下载一个客户端就可以很轻松的实现，现在我们用linux也想上网怎么办？我们也可以通过pppoe拨号连接到互联网

环境：

操作系统：CentOs  release 6.4

需要的软件：

rp-pppoe-3.11.tar.gz

我们先安装一个pppoe客户端

[root@localhost ~]# ll |grep ppoe

-rw-r--r--. 1 root root    223234 Apr 13 19:01 rp-pppoe-3.11.tar.gz

这是一个pppoe源代码包拆包解压到  /usr/local/src目录

  [root@localhost ~]# tar -zxvf rp-pppoe-3.11.tar.gz -C /usr/local/src

解压完后我们看看它的安装说明

  [root@localhost ~]# cd /usr/local/src

  [root@localhost src]# cd rp-pppoe-3.11/  

[root@localhost src]#ll

total 48

drwxr-xr-x. 2 user1 user1 4096 Aug 18  2012 scripts

drwxr-xr-x. 4 user1 user1 4096 Aug 18  2012 src

我们查看一下README安装说明

[root@localhost rp-pppoe-3.11]# vim README

Compile and install pppd if you don‘t already have it.  Then:

1) Unpack:

      $ tar xzvf rp-pppoe-xxx.tar.gz//已完成

2) Change to source directory://已完成

      $ cd src

3) Configure:

      $ ./configure// ./config配置编译规则

4) Compile:

      $ make

5) Install (this step must be done as root)

      # make install

6) Now read doc/HOW-TO-CONNECT

我们按照文件里的说明执行第三、四、五步

  [root@localhost rp-pppoe-3.11]# cd src

编译

  [root@localhost src]# ./configure

执行make

  [root@localhost src]# make

安装make install

  [root@localhost src]# make install

Type ‘make install‘ as root to install the software.

mkdir -p /usr/sbin

/usr/bin/install -c -m 755 pppoe /usr/sbin

/usr/bin/install -c -m 755 pppoe-server /usr/sbin

if test -x licensed-only/pppoe-server-control ; then /usr/bin/install -c -m 755 licensed-only/pppoe-server-control /usr/sbin; fi

Type ‘pppoe-setup‘ to configure the software.

让我们通过pppoe-setup来设置

设置pppoe

  [root@localhost src]# pppoe-setup

  提示设置用户名默认[email protected]

这里填写运营商给你提供的账户密码

[root@localhost rp-pppoe-3.11]# pppoe-setup

Welcome to the Roaring Penguin PPPoE client setup.  First, I will run

some checks on your system to make sure the PPPoE client is installed

properly...

Looks good!  Now, please enter some information:

USER NAME

>>> Enter your PPPoE user name (default 15638892360):

  输入用户名回车

  提示选择网卡默认eth0

INTERFACE

>>> Enter the Ethernet interface connected to the DSL modem

For Solaris, this is likely to be something like /dev/hme0.

For Linux, it will be ethn, where ‘n‘ is a number.

(default eth0):

  选择按需连接还是永久在线默认永久在线

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: Demand-activated links do not interact well with dynamic IP

addresses.  You may have some problems with demand-activated links.

>>> Enter the demand value (default no):

  提示让你输入你的IPS（Internet服务提供商）的主DNS 服务器地址

DNS

Please enter the IP address of your ISP‘s primary DNS server.

If your ISP claims that ‘the server will provide DNS addresses‘,

enter ‘server‘ (all lower-case) here.

If you just press enter, I will assume you know what you are

doing and not modify your DNS setup.

>>> Enter the DNS information here:

  输入密码和确认密码

PASSWORD

>>> Please enter your PPPoE password:    

>>> Please re-enter your PPPoE password:

配置防火墙，这里有三个级别

FIREWALLING

Please choose the firewall rules to use.  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):

  配置完成后会显示的的配置，并询问是否保存

** Summary of what you entered **

Ethernet Interface: eth0

User name:          

Activate-on-demand: No

DNS:                Do not adjust

Firewalling:        NONE

>>> Accept these settings and adjust configuration files (y/n)?

  保存后会提示配置的保存位置，并提示下一步操作

Adjusting /etc/ppp/pppoe.conf

Adjusting /etc/ppp/pap-secrets and /etc/ppp/chap-secrets

(But first backing it up to /etc/ppp/pap-secrets-bak)

(But first backing it up to /etc/ppp/chap-secrets-bak)

Congratulations, it should be all set up!

Type ‘pppoe-start‘ to bring up your PPPoE link and ‘pppoe-stop‘ to bring

it down.  Type ‘pppoe-status‘ to see the link status.

启动pppoe

[root@CentOS rp-pppoe-3.11]# pppoe-start

pppoe-start: There already seems to be a PPPoE connection up (PID 37234)
