在windows7下用pppoe就能拨号上网，但是linux下就不行了：

[root@tangkunyin ~]# cd /sbin

[root@tangkunyin sbin]# adls-setup

bash: adls-setup: command not found...

[root@tangkunyin sbin]# 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...

Enter your Login Name (default root): 02901105261

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): 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): 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: server

PASSWORD

Please enter your Password:

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): 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): 2

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 **

Ethernet Interface: eth0

User name: 02901105261

Activate-on-demand: No

DNS addresses: Supplied by ISP's server

Firewalling: MASQUERADE

User Control: yes

Accept these settings and adjust configuration files (y/n)? y

Adjusting /etc/sysconfig/network-scripts/ifcfg-ppp0

Adjusting /etc/ppp/chap-secrets and /etc/ppp/pap-secrets

(But first backing it up to /etc/ppp/chap-secrets.bak)

(But first backing it up to /etc/ppp/pap-secrets.bak)

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.
