[求助]超难问题 fc6的网络问题

xdf008

我把fc6的ip地址,网关,子网掩码,域名服务器都设成和xp里的一样了,可为什么xp能上网,而fc6不能上网?还有网关,子网掩码,域名服务器的ip都能ping 通的,用域名ping不通...在同一个网段的机器上的web服务能访问,他们也可以访问我机器上的web服务,可网上不去,为什么?

好难。。不会。。。= =;

nslookup 试试
$ nslookup www.google.com

[yichi@localhost ~]$ nslookup www.google.com
Server:         211.147.6.4
Address:        211.147.6.4#53

Non-authoritative answer:
www.google.com  canonical name = www.l.google.com.
www.l.google.com        canonical name = www-china.l.google.com.
Name:   www-china.l.google.com
Address: 64.233.189.104


请先确定不是 DNS 的问题。

个人意见和楼上的一致，偏向于是DNS的问题

确认网关是否同一网段?
    要不改本机IP最后地址为254为网关， 我以前发生过类似的现象。不知原因，但有解决;
XP: IP=172.28.84.23 网关=172.28.85.254
改为 Linux： IP=172.28.84.23 网关=172.28.84.254
通过。

     当然我上网用代理，还是而要在firevox及Konqueror中设定相关参数 .  Mail收发也没问题.

楼主说了：还有网关,子网掩码,域名服务器的ip都能ping 通的
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
由上可知：
如果楼主没有弄错网关，那么是不用考虑是否是在同一网段的。

还是老意见，认为是楼主本机的DNS设置错误

我感觉FC6的网络也有点点问题，比如Firefoc上网不知怎么搞的老是连接被重置！！！（XP下面不存在）
下东西也是Multiget下着下着速度就变为0，过一会儿又慢慢上升，迅雷下同样的就不会！！！不知什么原因？？

在命令行下：ifconfig
把结果贴出来
还有：vi  /etc/resolv.conf
这个结果也贴出来
大家好帮你查问题
