linux – samsung S7 android无法连接而且没有设置网络配置
作者：互联网
通过USB将Samsung S7连接到您最喜爱的Linux机器.转到’设置 – >连接 – >移动热点和Tethering’并启用“USB tethering”.
Android现在将启用与Linux主机的网络共享,因此Linux应该从手机获取IP地址.这是它被打破的地方.永远不会进行正确的网络设置以允许与手机本身进行任何IP连接.
问题是三星S7发送无效/损坏的Mac地址：00：00：00：00：00：00.并且Linux网络堆栈根本不使用“零”mac地址.
这个问题似乎与三星S7(android 6.x和7.x)一起推出.我以前的手机三星S4和S5是没有问题的网络共享.
我正在使用NetworkManager运行Fedora 24/25,但任何Linux都很可能会暴露同样的问题.
PS：与Win7-64绑定工作

解决方法:
Linux网络堆栈不适用于具有“零”MAC地址的接口.尝试设置网络配置时,与Android手机的网络共享设置只是在Linux端暂停.
此时,通过手动设置界面和路由,以下内容适用于我.我把它包装在一个shell脚本中：
# cat tetherS7_nwsetup.sh
IFNAME=enp0s20u4
ip a add 192.168.42.2/24 brd + dev $IFNAME
ip link set dev enp0s20u3 address e8:2a:ea:01:02:03
ip link set dev $IFNAME up
route add default gw 192.168.42.129
echo "nameserver 8.8.8.8" >>/etc/resolv.conf
更改IFNAME并输入您的界面名称.然后执行：
# chmod +x tetherS7_nwsetup.sh
# sudo ./tetherS7_nwsetup.sh
对于DNS,我目前正在使用Google的DNS服务器.随意改变.
希望这些步骤对你有用.
