RH要先设置网卡#netconf

把IP和DNS设置成如下的。

IP地址：192.168.0.1

掩码：

255.255.255.0

DNS (下面以广东佛山为例，各地的ISP 均有不同的DNS )

202.96.134.133

202.96.168.68

不要设置网关

然后再来设置ADSL。这一处，我们要用命令。

#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): 在这里输入ADSL的用户名

INTERFACE

>>> Enter the Ethernet interface connected to the ADSL modemFor Solaris, this is likely to be something like /dev/hme0.

For Linux, it will be ethn, where 'n' is a number.(default eth0):如果一张网卡就设置写上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 secondsafter 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):不用写什么

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:在这里写上202.96.134.133 下一个DNS是202.96.168.68

PASSWORD

>>> Please enter your PPPoE password:输入密码

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

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 whichallocate 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):这里添写为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)?

弄完后，就按一个y键。

用adsl-start来启动ADSL。如果不成功就重启一下计算机。

如果再不成功呢？？？？要发以下文件的内容：

/etc/sysconfig/network-scripts/ifcfg-eth0

/etc/ppp/pppoe.conf

/etc/resolv.conf

/etc/sysconfig/network-scripts/net_cnx_up
