首先配置pppoe撥號上網 步驟如下

在終端中輸入： #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): 在這里輸入ADSL用戶名

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):如果一個網卡就在這里輸入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):直接回車

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:在這里輸入server 即自動獲得DNS

PASSWORD

>;>;>; Please enter your PPPoE password:輸入ADSL密碼

>;>;>; Please re-enter your PPPoE password:再輸入一次

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):這里輸入0，可自選，英文水平有點的都懂

** Summary of what you entered **

Ethernet Interface: eth0

User name: XXX

Activate-on-demand: No

DNS: Do not adjust

Firewalling: MASQUERADE

>;>;>; Accept these settings and adjust configuration files (y/n)?這里輸入y即可，輸入n就是重頭設置過。

配置完成！

配置完成之后 當然不要忘記激活我們的網卡eth0 啦！ 我就在這里想了好久都沒想到~ 呵呵 說實在的是無意當中想到這方法就順便試試的 沒想到真成功了！

具體步驟如下~

我裝的是雙系統（xp+fedora9） 首先在xp下用ipconfig/all獲取eth0的ip地址和dns 當然咯這里的默認網關可能為空（我的就是），不過沒關系，把這里顯示的ip和dns記錄下來， 然后轉入fedora9 把剛記錄的ip和dns數據寫進eth0手動設置ip和dns里邊~ 重啟系統， 進來之后也許你會發現還是不行，不急，再在終端里輸入“service network restart”重啟network服務即可。
