无法访问互联网 Virtualbox

我无法从 Ubuntu 中的 VirtualBox 连接到互联网 -

以下是我运行的 nslookup 命令 -

[cloudera@quickstart ~]$ nslookup
> server 8.8.8.8
Default server: 8.8.8.8
Address: 8.8.8.8#53
> www.google.com
;; connection timed out; trying next origin
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached
>

/etc/resolv.conf 文件配置 -

[cloudera@quickstart ~]$ cat /etc/resolv.conf

请告诉我如何解决这个问题

ip rs 的输出

10.0.2.0/24 dev eth0  proto kernel  scope link  src 10.0.2.15  metric 1 
192.168.56.0/24 dev eth1  proto kernel  scope link  src 192.168.56.0 
169.254.0.0/16 dev eth1  scope link  metric 1003 
default via 10.0.2.2 dev eth0  proto static

答案1

我看到的是，您没有任何默认网关。

添加一个与你的虚拟机相关的：

sudo ip route add default via 10.0.2.2

然后尝试ping，，，等：dignslookup

$ ping -c 4 8.8.8.8

$ nslookup askubuntu.com

还要确保您的 VirtualBox 配置正确。

答案2

您所要做的就是重置配置文件。这可以在一行命令中完成

sudo ifdown eth0; sudo ifup eth0
