查看一下/etc/sysconfig/networking目录下的配置文件
/etc/sysconfig/networking 目录下的配置文件优先于 /etc/sysconfig/network-scripts目录下的配置;
另外 nslookup
www.google.cn 看下效果
[root@localhost ~]# nslookup
www.google.cn
Server: 10.10.0.27
Address: 10.10.0.27#53
Non-authoritative answer:
www.google.cn canonical name = cn.l.google.com.
Name: cn.l.google.com
Address: 203.208.35.101
Name: cn.l.google.com
Address: 203.208.35.100
最后查一下firefox设置,是否脱机状态等
