Zero通過OTG共享PC網絡 · 荔枝派Zero指南

# Zero通過otg與PC共享網絡在內核選項中勾選上：composite gadget: Serial and Ethernet. 就可以讓Zero與PC通過usb共享網絡。 ## 確認usb虛擬網口被使能使用usb線連接Zero和PC，在Zero和PC上查看網絡接口： ~~~ zp@ubuntu64:~$ ifconfig ... usb0 Link encap:Ethernet HWaddr 66:36:e9:13:fd:44 root@Lichee:~# ifconfig ... usb0 Link encap:Ethernet HWaddr 2e:cf:e1:3f:ad:61 ~~~ 確認有usb0接口后，手工設置兩者在同一網段下： ~~~ on PC: sudo ifconfig usb0 192.168.2.1 on Zero: sudo ifconfig usb0 192.168.2.100 ~~~ Test PC ping Zero: zp@ubuntu64:~$ ping 192.168.2.100 PING 192.168.2.100 (192.168.2.100) 56(84) bytes of data. 64 bytes from 192.168.2.100: icmp_seq=1 ttl=64 time=2.74 ms 64 bytes from 192.168.2.100: icmp_seq=2 ttl=64 time=2.19 ms ... Everything is ok now, let's edit network config(/etc/network/interfaces) to save it: On PC add: allow-hotplug usb0 auto usb0 iface usb0 inet static address 192.168.2.1 netmask 255.255.255.0 On Zero add: allow-hotplug usb0 auto usb0 iface usb0 inet static address 192.168.2.100 netmask 255.255.255.0 gateway 192.168.2.1 Share Network from PC Enable forwarding on your PC: echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward > /dev/null sudo iptables -P FORWARD ACCEPT sudo iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.2.0/24 test Ping google (if you are in china, ping baidu.com please...) ping google.com If everything goes ok, your Zero is online now~ You can ssh to Zero on your PC or any PC in the local net. zp@ubuntu64:~$ ssh root@192.168.2.100 root@192.168.2.100's password: Linux Lichee 4.10.2-licheepi-zero+ #12 SMP Wed Mar 15 23:22:13 CST 2017 armv7l The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.
