RedHat系統ADSL配置指南(轉)

RedHat系統ADSL配置指南(轉)[@more@]

　　本文用注視加命令列提示的方式從安裝例項的角度為初學linux的朋友闡述了Red Hat中用ADSL撥號上網的詳細過程，希望可以給遇到此困難的朋友以幫助。

　　首先應該確定您是否安裝了pppoe的應用程式。如果確實已經安裝了，可以在終端用 adsl－setup命令啟動adsl配置，提示過程為英文。大概為:

　　[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 //預設為ppp0

　　LOGIN NAME

　　Enter your Login Name (default SJ00411210A1): anthrax //這裡用你自己的使用者名稱代替我的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 //預設網路卡裝置為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 //這裡使用預設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地址設定，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地址設定。

　　PASSWORD

　　Please enter your Password: //這裡設定密碼，和unix規則一樣，密碼並不回顯，因此不要認為您的鍵盤出了毛病:)

　　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 //是否允許普通使用者共享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 //是否允許開機自動載入，這裡選擇no，否則系統啟動速度太慢!

　　** 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命令啟動，可以用adsl－stop命令停止。

　　為了方便，可以在桌面建立一個應用程式連結，命令就使用adsl－start。這樣每次雙擊那個快捷圖示就可以建立adsl連結了，跟windows中一樣方便。

　　好了，現在就開始您的網路之旅吧。(技巧:如果依據本文內容操作扔不能連結網路，可以嘗試在"系統設定－>網路"中刪除當前的網路卡，重新配置adsl項。)
