FC5下无法上网。

Fomalhaut

以前使用网通ADSL在FC5下上网，设置非常容易，几乎不费什么事，自从换了长城互联网的宽带业务以后，怎么设置都不行。浏览器里面什么网址都打不开。我把DNS设置成211.166.0.166 211.166.0.168连接的时候没有任何错误提示，但是到了浏览器里面就是什么网址都打不开。而且发现PPP0总是无法激活，eth0可以激活。
我不知道是不是和我的网络连接环境有关?
我的小区属于那种部队的家属住宅小区，电脑通过小区内部的军线电话线和小区自己的电话机房连接，然后再和部队连接，最后才是长城互联网
个人电脑——小区电话机房——XXX（这里应该还有一个军事机关，但是搞不清楚到底是什么？）——总参机房——长城宽带

我除了在更换宽带的时候换了个猫意外。什么也没用动。不知道是那里的问题？

原来的操作
# vi /etc/sysconfig/network
GATEWAY=
GATEWAYDEV=
两项后面都是空的

# vi /etc/sysconfig/network-scripts/ifcfg-eth0
ONBOOT=YES
BOOTPROTP=DHCP

# /etc/rc.d/init.d/network restart

然后就是设置rp-pppoe
# /usr/sbin/adsl-setup
每一步都是按照规定填写的，而且我几乎天天上网，不可能记错帐号，密码。但是就是上不了网
到底是什么地方的问题?（RP-PPPOE肯定是安装了的）

[root@localhost ~]# /usr/sbin/adsl-setup
Welcome to the ADSL 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): hjzy10068
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 ethX, where 'X' 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 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: 211.166.0.166
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: 211.166.0.168
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):
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):
** Summary of what you entered **
Ethernet Interface: eth0

Accept these settings and adjust configuration files (y/n)? y
Adjusting /etc/sysconfig/network-scripts/ifcfg-ppp0
Adjusting /etc/resolv.conf

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/adsl-status /etc/sysconfig/network-scripts/ifcfg-ppp0'
to see the link status.
[root@localhost ~]# adsl-start
[root@localhost ~]#

PPP0无法激活时的提示
sbin/adsl-start: line 216:  3915 Terminated              $CONNECT "$@" >/dev/null 2>&1
请问这是什么地方的问题？为什么我在WIN XP和FC5 LINUX下的网络IP
配置状态会有这么大区别？:ask

拜托了，有人知道吗？这个问题已经困扰我3个多星期了。
