Linux下pppoe設置

 在Linux下配置pppoe，一般有以下步驟：

1. 安裝pppoe軟件。這個不多說，ape-get install pppoe即可。

2. 設置撥號屬性：

root@ubuntu:~# pppoe-setup

   詳細過程如下：

     用戶名：

USER NAME

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

     接口(網卡)：

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): eth0

      dns：

>>> Enter the DNS information here:

      密碼：

PASSWORD

>>> Please enter your PPPoE password:    
>>> Please re-enter your PPPoE password: 

      防火牆：

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

   保存設置：

Ethernet Interface: eth0
User name:          test
Activate-on-demand: No
DNS:                Do not adjust
Firewalling:        NONE

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

  保存成功了。

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.

3. 開始撥號

root@ubuntu:~# pppoe-start

到了這一步，如果沒有問題的話，應該就可以正常連上pppoe服務器了。

 

 

但在實際操作時，我遇到了以下兩個問題：

問題1：

root@ubuntu:~# 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...

Oops, I can't execute the program '/usr/local/sbin/pppd'.  You
must install the PPP software suite, version 2.3.10 or later.

   原因：目錄/usr/local/sbin/沒有pppd文件

   解決方法：

     將/usr/sbin/pppoe-setup腳本里PPPD=/usr/local/sbin/pppd
     改爲PPPD=/usr/sbin/pppd，保存修改後即恢復可正常

 

問題2：

root@ubuntu:~# pppoe-status: Link is down (can't read pppoe PID file /var/run/pppoe.conf-pppoe.pid.pppoe)

    嘗試運行pppoe-connect，出現和問題一類似的錯誤

   原因：同問題1所述

   解決方法和問題1中類似：
     將/usr/sbin/pppoe-connect腳本里PPPD=/usr/local/sbin/pppd
     改爲PPPD=/usr/sbin/pppd，保存修改後即恢復可正常

總結：

       在配置pppoe時遇到奇怪的問題，很有可能是有相應的腳本的路徑設置不當造成。
