唉，大神们都不在呢，好失望呀！

xingnifeng · #4

终于解决了，看来还是得靠自己啊。

解决方案：
1. sudo echo "nameserver primary_dns" > /etc/resolv.conf
2. sudo echo "nameserver sencery_dns" > /etc/resolv.conf
3. sudo ifconfig usb0 $1 netmask 255.255.255.255 -arp
4. sudo ip r add $2 dev usb0
5. sudo ip r add 0.0.0.0/0 via $2 dev usb0

$1: ip地址
$2：ip地址的下一跳
