我已经从 Beaglebone Black 板上的 SD 卡启动了 Debian Wheezy。版本:debian-wheezy-7.0.0-armhf-3.8.13-bone20.img.xz,来自http://www.armhf.com/index.php/download/
我已经设置了 /etc/networks/interfaces 文件:
auto lo
iface lo inet loopback
auto eth2
iface eth2 inet static
address 192.168.1.101
netmask 255.255.255.0
gateway 192.168.1.2
dns-nameservers 8.8.8.8 8.8.8.9
# wireless network interface
#auto wlan0
#iface wlan0 inet dhcp
当我 ping 8.8.8.8 时:
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_req=1 ttl=44 time=32.3 ms

但是当我 ping google.com 时
ping: unknown host google.com
我也可以 ping 通网络上的其他设备,但无法访问互联网。
知道出了什么问题吗?

答案1
您需要将 DNS 设置添加到该/etc/resolv.conf
文件中。如果您编辑该文件以包含类似以下内容,它应该可以工作:
nameserver 8.8.8.8
答案2
辅助服务器的地址是 8.8.4.4,而不是 8.8.8.9。
答案3
为了使该dns-nameservers
指令起作用,/etc/network/interfaces
您需要有一个单独的包resolvconf
。您可以检查/etc/resolv.conf
一下接口是否存在。如果不是,请安装该resolvconf
软件包并重新启动界面:
apt-get install resolvconf
ifdown eth2
ifup eth2
