Linux下pppoe设置

 在Linux下配置pppoe，一般有以下步骤：

1. 安装pppoe软件。这个不多说，ape-get install pppoe即可。

2. 设置拨号属性：

root@ubuntu:~# pppoe-setup

   详细过程如下：

     用户名：

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

     接口(网卡)：

INTERFACE>>> Enter the Ethernet interface connected to the DSL modemFor 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:

      密码：

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

      防火墙：

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 workstation2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway                for a LAN>>> Choose a type of firewall (0-2): 0

   保存设置：

Ethernet Interface: eth0User name:          testActivate-on-demand: NoDNS:                Do not adjustFirewalling:        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 bringit down.  Type 'pppoe-status' to see the link status.

3. 开始拨号

root@ubuntu:~# pppoe-start

到了这一步，如果没有问题的话，应该就可以正常连上pppoe服务器了。

 

 

但在实际操作时，我遇到了以下两个问题：

问题1：

root@ubuntu:~# pppoe-setupWelcome to the Roaring Penguin PPPoE client setup.  First, I will runsome checks on your system to make sure the PPPoE client is installedproperly...Oops, I can't execute the program '/usr/local/sbin/pppd'.  Youmust install the PPP software suite, version 2.3.10 or later.

   原因：目录/usr/local/sbin/没有pppd文件

   解决方法：

     将/usr/sbin/pppoe-setup脚本里PPPD=/usr/local/sbin/pppd
     改为PPPD=/usr/sbin/pppd，保存修改后即恢复可正常

 

问题2：

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

    尝试运行pppoe-connect，出现和问题一类似的错误

   原因：同问题1所述

   解决方法和问题1中类似：
     将/usr/sbin/pppoe-connect脚本里PPPD=/usr/local/sbin/pppd
     改为PPPD=/usr/sbin/pppd，保存修改后即恢复可正常

总结：

       在配置pppoe时遇到奇怪的问题，很有可能是有相应的脚本的路径设置不当造成。
