Linux下pppoe设置

时间:2022-09-20 17:30:16

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:

[cpp] view plain copy

  1. root@ubuntu:~# pppoe-setup 

   详细过程如下:

     用户名:

[cpp] view plain copy

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

     接口(网卡):

[cpp] view plain copy

  1. INTERFACE 
  2. >>> Enter the Ethernet interface connected to the DSL modem 
  3. For Solaris, this is likely to be something like /dev/hme0. 
  4. For Linux, it will be ethn, where 'n' is a number. 
  5. (default eth0): eth0 

      dns:

[cpp] view plain copy

  1. >>> Enter the DNS information here: 

      密码:

[cpp] view plain copy

  1. PASSWORD 
  2. >>> Please enter your PPPoE password:     
  3. >>> Please re-enter your PPPoE password:  

      防火墙:

[cpp] view plain copy

  1. The firewall choices are: 
  2. 0 - NONE: This script will not set any firewall rules.  You are responsible 
  3. for ensuring the security of your machine.  You are STRONGLY 
  4.           recommended to use some kind of firewall rules. 
  5. 1 - STANDALONE: Appropriate for a basic stand-alone web-surfing workstation 
  6. 2 - MASQUERADE: Appropriate for a machine acting as an Internet gateway 
  7. for a LAN 
  8. >>> Choose a type of firewall (0-2): 0 

   保存设置:

[cpp] view plain copy

  1. Ethernet Interface: eth0 
  2. User name:          test 
  3. Activate-on-demand: No 
  4. DNS:                Do not adjust 
  5. Firewalling:        NONE 
  6. >>> Accept these settings and adjust configuration files (y/n)? y 

  保存成功了。

[cpp] view plain copy

  1. Congratulations, it should be all set up! 
  2. Type 'pppoe-start' to bring up your PPPoE link and 'pppoe-stop' to bring 
  3. it down.  Type 'pppoe-status' to see the link status. 

3. 开始拨号

[cpp] view plain copy

  1. 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:

[cpp] view plain copy

  1. root@ubuntu:~# pppoe-setup 
  2. Welcome to the Roaring Penguin PPPoE client setup.  First, I will run 
  3. some checks on your system to make sure the PPPoE client is installed 
  4. properly... 
  5. Oops, I can't execute the program '/usr/local/sbin/pppd'.  You 
  6. must 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:

[cpp] view plain copy

  1. 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。
