解压和安装：
　　#tar zxvf rp-pppoe-3.5.tar.gz

　　进入解压目录执行：
　　#sh ./go

　　然后再来设置ADSL，这里，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 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 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 //这里根据个人不同可以修改
　　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 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):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。 
　　不要急于连接,REBOOT -N
　　然后进入网络设置,设置ETH1固定IP，停止ETH1(我的是用他)
　　然后ADSL-START PING 你的DNS,如果可以,那么,恭喜你!
　　如果不行，REBOOT -N
　　ADSL-START,这下没问题啦，尽情享受吧！
　　其中部分内容可能不同,仅作参考,主要在连接后,能够PING通DNS即可!
