Ubuntu 服务器无法访问互联网，但可以使用 SSH

Question

因此，如上所述，我可以远程访问我的服务器，并使用 SSH 在本地访问，但是我无法访问“互联网”。我的意思是我无法访问网页。

dtipp@mc-server:~$ ping www.google.com
ping: unknown host www.google.com

这就是我尝试 ping google 时得到的结果。

dtipp@mc-server:~$ curl -s checkip.dyndns.org | sed -e 's/.*Current IP Address: //' -e 's/<.*$//'  

不会像以前那样产生 ip 地址。我所有的问题都是在尝试设置静态 IP 地址后开始的。我终于设法让我的文件看起来像我认为应该的那样，但只是现在问题才开始。

dtipp@mc-server:~$ ifconfig

这是安装文件，以及其他一些 ping 操作的结果。我做错了什么还是我需要做一些额外的事情？

设置静态IP地址时，还必须设置DNS名称服务器。建议您修改/etc/network/interfaces为：

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
    address 192.168.1.120
    netmask 255.255.255.0
    gateway 192.168.1.1
    dns-nameservers 192.168.1.1 8.8.8.8

重启界面：

sudo ifdown eth0 && sudo ifup -v eth0

测试：

ping -c3 www.ubuntu.com

您的 /etc/resolv.conf 也不正确。请修改：

nameserver 127.0.1.1
