ljs2002

我用pppoe拨号成功可是连不上网，ping dns地址，没有回应，ping网关192.168.0.1可以
我把在终端下操作过程复制了，想让大家帮忙看一下，是怎么回事？

root@slax:~# pppoe-setup
Welcome to the Roaring Penguin PPPoE 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 bxxxnxnx@sympatico.ca): sy_lijing

INTERFACE

>>> Enter the Ethernet interface connected to the DSL 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):

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 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: 202.96.69.38
Please enter the IP address of your ISP's secondary DNS server.
If you just press enter, I will assume there is only one DNS server.
>>> Enter the secondary DNS server address here: 202.96.64.68

PASSWORD

>>> Please enter your PPPoE password:
>>> Please re-enter your PPPoE password:

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

** Summary of what you entered **

Ethernet Interface: eth0
User name:          sy_lijing
Activate-on-demand: No
Primary DNS:        202.96.69.38
Secondary DNS:      202.96.64.68
Firewalling:        NONE

>>> Accept these settings and adjust configuration files (y/n)? y
Adjusting /etc/ppp/pppoe.conf
Adjusting /etc/resolv.conf
  (But first backing it up to /etc/resolv.conf-bak)
Adjusting /etc/ppp/pap-secrets and /etc/ppp/chap-secrets
  (But first backing it up to /etc/ppp/pap-secrets-bak)
  (But first backing it up to /etc/ppp/chap-secrets-bak)



Congratulations, it should be all set up!

Type 'pppoe-start' to bring up your PPPoE link and 'pppoe-stop' to bring
it down.  Type 'pppoe-status' to see the link status.
root@slax:~# pppoe-start

你随便ping 一个域名,试试能否ping通。Adsl经常出现假连接。
