Debian 8.2 中失去互联网连接

我读过很多阿库本图以及其他有关互联网连接丢失的论坛帖子。我在笔记本电脑上安装了 Debian 8.2 Jessy，并使用静态 IPv4 配置：

  • IP 地址10.0.0.5
  • 面罩 255.255.255.0
  • 网关10.0.0.138
  • Dns 8.8.8.8（Google 的 DNS）+ ISP 的 DNS

有效。然后，经过一番处理后，连接不知从哪里丢失了。我尝试 ping 路由器：

root@debian82:/home/user# ping 10.0.0.138
PING 10.0.0.138 (10.0.0.138) 56(84) bytes of data.

我尝试过 ping Google：

root@debian82:/home/user# ping google.com ping: unknown host
google.com

我尝试切换到 dhcp 并刷新其配置：

root@debian82:/home/user# dhclient -r -v eth0 && rm
/var/lib/dhcp/dhclient.*; dhclient -v eth0 Internet Systems Consortium

这是我得到的：

allow-hotplug eth0
auto eth0
iface eth0 inet dhcp
#       address 10.0.0.11
#       netmask 255.255.255.0

        nameserver 194.90.0.1
        dns-nameservers 8.8.8.8 194.90.0.1 8.8.4.4

我尝试了所有可能找到的东西，并在每次尝试之间重新启动。我哪里错了？内容为/etc/resolv.conf是：

user@debian82:~$ nano /etc/resolv.conf
nameserver 10.0.0.138

编辑：我已将其他名称服务器（Google 和 ISP）添加到/etc/resolv.conf.我是在没有互联网的计算机上写这篇编辑的。

答案1

添加其他名称服务器来/etc/resolv.conf解决该问题。之前看起来像：

user@debian82:~$ nano /etc/resolv.conf
nameserver 10.0.0.138

现在看起来像：

user@debian82:~$ nano /etc/resolv.conf
nameserver 10.0.0.138
nameserver <ISP's dns name server>
nameserver 8.8.8.8 <(Google's)>

并且连接已恢复：
