127.0.0.0 audit.median.hu
[root@MYPC etc]# ping audit.median.hu
Do you want to ping broadcast? Then -b
[root@MYPC etc]# host -t a audit.median.hu
audit.median.hu has address 193.68.35.149
audit.median.hu has address 193.91.69.232
audit.median.hu has address 193.68.35.131
audit.median.hu has address 193.68.35.136
为什么ping
显示的audit.median.hu
是 127.0.0.0,为什么host -t a audit.median.hu
显示的是 193.68.35.149?audit.median.hu
只是一个示例站点 [托管广告等]
我的 Fedora PC 上只有一个缓存名称服务器:
yum -y install caching-nameserver
service named restart
chkconfig named on
我在网络管理器小程序中配置了我的 DNS 服务器地址:127.0.0.1、8.8.8.8
即使使用 Wireshark,我也可以看到它:
`195.70.37.149 DNS Standard query A audit.median.hu`
所以最大的问题是:为什么命令或我的网络浏览器无法host
识别我已修改的audit.median.hu
IP 地址?
答案1
你/etc/nsswitch.conf
有吗
hosts: files dns
放?
