RedHat系統ADSL配置指南

　　首先應該確定您是否安裝了pppoe的應用程序。

　　如果確實已經安裝了，可以在終端用 adsl－setup命令啓動adsl配置，提示過程爲英文。

　　大概爲:

[root@localhost root]# adsl-setup
Welcome to the ADSL client setup. First, I will run some checks on
your system to make sure the PPPoE client is installed properly...

The following DSL config was found on your system:

Device: Name:
ppp0 DSLppp0

Please enter the device if you want to configure the present DSL config
(default ppp0) or enter 'n' if you want to create a new one: ppp0 //默認爲ppp0

LOGIN NAME

Enter your Login Name (default SJ00411210A1): anthrax //這裏用你自己的用戶名代替我的anthrax:)

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 ethX, where 'X' is a number.
(default eth0): eth0 //默認網卡設備爲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): no //這裏使用默認no就可以了，斷線後不自動撥號。


DNS

Please enter the IP address of your ISP's primary DNS server.
If your ISP claims that 'the server will provide dynamic 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: 202.96.134.133 //主DNS地址設置，根據您的具體情況替換。
Please enter the IP address of your ISP's secondary DNS server.
If you just press enter, I will assume there is only one DNS server.
Enter the secondary DNS server address here: 202.96.134.133 //第二DNS地址設置。

PASSWORD

Please enter your Password: //這裏設置密碼，和unix規則一樣，密碼並不回顯，因此不要認爲您的鍵盤出了毛病:)
Please re-enter your Password:
//確認密碼
USERCTRL

Please enter 'yes' (two letters, lower-case.) if you want to allow
normal user to start or stop DSL connection (default yes): yes //是否允許普通用戶共享ADSL。

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): 1 //配置防火牆等級，根據您的需要選擇。

Start this connection at boot time

Do you want to start this connection at boot time?
Please enter no or yes (default no):no //是否允許開機自動加載，這裏選擇no，否則系統啓動速度太慢!

** Summary of what you entered **

Ethernet Interface: eth0
User name: anthrax
Activate-on-demand: No
Primary DNS: 202.96.134.133
Secondary DNS: 202.96.134.133
Firewalling: STANDALONE
User Control: yes
Accept these settings and adjust configuration files (y/n)?


　　選擇y，配置完成。您可以用 adsl－start命令啓動，可以用adsl－stop命令停止。

　　爲了方便，可以在桌面建立一個應用程序鏈接，命令就使用adsl－start。這樣每次雙擊那個快捷圖標就可以建立adsl鏈接了，跟windows中一樣方便。

　　好了，現在就開始您的網絡之旅吧。(技巧:如果依據本內容操作扔不能鏈接網絡，可以嘗試在"系統設置－>網路"中刪除當前的網卡，重新配置adsl項。)
