我有新的 ubuntu 安装。我的网络是使用 dhcp 配置的。
$ ifconfig
enp5s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

我尝试为该接口指定静态配置
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto enp5s0
iface enp5s0 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 8.8.8.8
但
nmcli device show enp5s0 | grep IP4.DNS
不打印任何内容。
互联网可以访问，并且站点可以 ping 成功。
那么该怎么做呢？
更新：我已经能够检测到 8.8.8.8 dns 已被使用。
host -v www.news.com | grep Received
Received 89 bytes from 8.8.8.8#53 in 56 ms
Received 100 bytes from 8.8.8.8#53 in 101 ms
Received 100 bytes from 8.8.8.8#53 in 98 ms
但我不明白为什么
nmcli device show enp5s0 | grep IP4.DNS
什么也没显示。
