首先我们需要配置pppoe拨号上网 其步骤如下 ：

在终端中输入： #pppoe-setup

Welcome to the Roaring Penguin ADSL 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 XXX): 在这里输入ADSL用户名

INTERFACE

>;>;>; Enter the Ethernet interface connected to the ADSL 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):如果一个网卡就在这里输入eth0

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):直接回车

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:在这里输入server 即自动获得DNS

PASSWORD

>;>;>; Please enter your PPPoE password:输入ADSL密码

>;>;>; Please re-enter your PPPoE password:再输入一次
