而後再來設置ADSL。這一處，咱們要用命令。
#adsl-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): 在這裏輸入ADSL的用戶名
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):若是一張網卡就設置寫上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):不用寫什麼
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:在這裏寫上202.96.134.133
下一個DNS是202.96.168.68 //這裏根據我的不一樣能修改

PASSWORD
>>> Please enter your PPPoE password:輸入密碼
>>> 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):這裏添寫爲2
** 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)?
弄完後，就按一個y鍵。
