slackware 不能上网

[wrfwsh]

刚装上的时候是直接从第一个路由器连接来的，可以上网（开机后用dhclient eth0）然后就正常上网，
但后来，从第一个路由器再接出一个路由器，网关设为192.168.1.2，XP下是正常上网的，但是slackware却不知道是什么进修上不了网，命令都用过了，却一直得到IP　192.168.1.100　第二个路由器IP地址池是从192.168.1.100开始的

[aBiNg]

ifconfig -a 看下结果。

netconfig 选好 dhcp项。

[wrfwsh]

ifconfig -a
只看到　127.0.0.1
是选　了DHCP。

[aBiNg]

$more /etc/network/interfaces
$ifconfig -a

结果帖下吧。

[wrfwsh]

没有这个目录，只有文件，

Why is it called a funny bone when it hurts so much?

可能是dns服务器没配置上，看下 /etc/resolv.conf 文件吧。

分别测试下这两个 ping。

代码： 全选

ping -c 2 220.181.12.218
ping -c 2 126.com

[hujy]

应该是dns问题， /etc/resolv.conf中写入
nameserver x.x.x.x

[wrfwsh]

不是的。因为路由器是DHCP不启用。改为DHCP启用就行了。不过期间也上了一次网，不知道为什么
