Linux下pppoe客户端拔号--pppoe-setup

root@jlive:~#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...

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:
#拔号接口名

LOGIN NAME

Enter your Login Name (default 8280):
#ISP(电信，长城等)提供的用户名

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 br0):
#连接到PPPoE调制解调器的接口，我这里配置了桥接，所以用的br0

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):
#按需连接还是持续连接，no为持续连接

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:
#DNS设置，为空则使用ISP提供的DNS

PASSWORD

Please enter your Password:
Please re-enter your Password:
＃拔号密码

USERCTRL

Please enter 'yes' (three letters, lower-case.) if you want to allow
normal user to start or stop DSL connection (default yes):
#是否允许普通用户拔号

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
#防火墙配置

Start this connection at boot time

Do you want to start this connection at boot time?
Please enter no or yes (default no):

** Summary of what you entered **
