pppoe-setup

Welcome to the PPPoE client setup.  First, I will run some checks on

your system to make sure the PPPoE client is installed properly...

LOGIN NAME

Enter your Login Name (default root): test    # 输入拨号认证账户

INTERFACE

Enter the Ethernet interface connected to the PPPoE 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):                               # 默认以 eth0 连接拨号

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):

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:

PASSWORD

Please enter your Password:                   # 输入认证账户密码

Please re-enter your Password:

USERCTRL

Please enter 'yes' (three letters, lower-case.) if you want to allow

normal user to start or stop DSL connection (default yes):

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): 0

Start this connection at boot time

Do you want to start this connection at boot time?

Please enter no or yes (default no):no

** Summary of what you entered **

User name:          test

Activate-on-demand: No

DNS:                Do not adjust

Firewalling:        NONE

Congratulations, it should be all set up!

Type '/sbin/ifup ppp0' to bring up your xDSL link and '/sbin/ifdown ppp0'

to bring it down.

Type '/sbin/pppoe-status /etc/sysconfig/network-scripts/ifcfg-ppp0'

to see the link status.
