RedHat10下如何通过ADSL上网?
来源: 互联网 发布时间:2016-05-15
本文导语: 前一段时间我曾经成功设置过上网,大概是在图形界面里: 系统设置-->网络设置-->按windows下得到的ip地址,网关,dns的ip输入到网卡eth0及DNS里,然后点"激活",再打开浏览器就可以上网了. 现在重装了linux,按上面设置了一翻,却不能上...
前一段时间我曾经成功设置过上网,大概是在图形界面里:
系统设置-->网络设置-->按windows下得到的ip地址,网关,dns的ip输入到网卡eth0及DNS里,然后点"激活",再打开浏览器就可以上网了.
现在重装了linux,按上面设置了一翻,却不能上网,比如要上google,就提示unknow host,
我怀疑是网卡驱动有问题,就ping了一下网关地址(在同一台机器的windows系统下是能ping通的,说明硬件没问题),
但却显示destination unreachable,
请问这是怎么回事啊?

如果DNS没错的话,看看这个
一般redhat 9直接使用dhcp是有一个bug的
需要在/etc/sysconfig/network-script/ifcfg-eth0
里加上
check_link_down() {
return 1;
}
我以前用RH9确实有这个情况,按上面情况修改后就没问题了
如果真的有问题,你的网卡应该是一直激活失败的

rp-pppoe-3.5.tar.gz
rp-pppoe-3.7.tar.gz
rp-pppoe-3.8.tar.gz
本文用注视加命令行提示的方式从安装实例的角度为初学linux的朋友阐述了Red Hat中用ADSL拨号上网的详细过程,希望可以给遇到此困难的朋友以帮助。
首先应该确定您是否安装了pppoe的应用程序。如果确实已经安装了,可以在终端用 adsl-setup命令启动adsl配置,提示过程为英文。大概为:
[root@localhost root]# 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...
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: ppp0 //默认为ppp0
LOGIN NAME
Enter your Login Name (default SJ00411210A1): anthrax //这里用你自己的用户名代替我的anthrax:)
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): eth0 //默认网卡设备为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 //这里使用默认no就可以了,断线后不自动拨号。
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: 202.96.134.133 //主DNS地址设置,根据您的具体情况替换。
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: 202.96.134.133 //第二DNS地址设置。
PASSWORD
Please enter your Password: //这里设置密码,和unix规则一样,密码并不回显,因此不要认为您的键盘出了毛病:)
Please re-enter your Password:
//确认密码
USERCTRL
Please enter "yes" (two letters, lower-case.) if you want to allow normal user to start or stop DSL connection (default yes): yes //是否允许普通用户共享ADSL。
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 accessto 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 Internetgateway for a LAN
Choose a type of firewall (0-2): 1 //配置防火墙等级,根据您的需要选择。
Start this connection at boot time
Do you want to start this connection at boot time?
Please enter no or yes (default no):no //是否允许开机自动加载,这里选择no,否则系统启动速度太慢!
** Summary of what you entered **
Ethernet Interface: eth0
User name: anthrax
Activate-on-demand: No
Primary DNS: 202.96.134.133
Secondary
DNS: 202.96.134.133
Firewalling: STANDALONE
User Control: yes
Accept these settings and adjust configuration files (y/n)?
选择y,配置完成。您可以用 adsl-start命令启动,可以用adsl-stop命令停止。
为了方便,可以在桌面建立一个应用程序链接,命令就使用adsl-start。这样每次双击那个快捷图标就可以建立adsl链接了,跟windows中一样方便。

先装个ADSL的客户端软件
然后在/etc/sysconfig/network-scripts/ifcfg-eth0
中设置网卡的信息。及网关
如下:
# VIA Technologies, Inc. VT6105 [Rhine-III]
DEVICE=eth1
BOOTPROTO=static
BROADCAST=192.168.0.255
HWADDR=00:13:46:72:9E:52
IPADDR=192.168.0.4
NETMASK=255.255.255.0
NETWORK=192.168.0.0
ONBOOT=yes
再设置DNS:/etc/resolv.conf
nameserver x.x.x.x
然后在/etc/sysconfig/network-scripts/ifcfg-eth0

BROADCAST=192.168.0.255

IPADDR=192.168.0.4
NETMASK=255.255.255.0
NETWORK=192.168.0.0
ONBOOT=yes
再设置DNS:/etc/resolv.conf
nameserver x.x.x.x

还是不行的话,贴出:
#route -n
#route -n

我怀疑是在安装时,到了设置防火墙那一步,有一个"来自eth0的所有应用",我给勾上了,
但是它是不是要禁止eth0的意思?
=============================================================
Desktop->System Setting->Security Level
在Trusted devices 里eth0打上勾.
点OK.
