我正在运行 Linux 的 Intel Galileo Gen 2 上尝试此操作Yocto
,但无法使用以太网连接到互联网。我有 WiFi 卡,但也无法连接。我尝试过以下命令,它们的输出如下
ifconfig -a
输出:

界面如下所示:
vi /etc/network/interfaces
auto enp0s20f6
iface enp0s20f6 inet static

netmask 255.255.255.0
auto wlan0

auto lo
iface lo inet loopback
经过尝试connmanctl services
我得到,
*AR Wired ethernet_984fee019eca_cable
*A wifinw wifi_448500018ad3_646c696e6b2d32333238_managed_psk
所以ping www.google.com
失败了bad address
。我尝试过ping 8.8.8.8
,它给出了回应。根据@frarugi87,这是一个 DNS 问题,但我不知道如何解决这个问题。
有/etc/resolv.conf
以下名称服务器
# Generated by Connection Manager
nameserver 127.0.0.1
nameserver ::1
答案1
将 OpenDNS 服务器添加到我的/etc/resolv.conf
文件中解决了这个问题。
vi /etc/resolv.conf
文件看起来像
nameserver 208.67.222.222
nameserver 208.67.220.220
此后,可以 ping 到 google.com。
