# Zero通过otg与PC共享网络 在内核选项中勾选上：composite gadget: Serial and Ethernet. 就可以让Zero与PC通过usb共享网络。 ## 确认usb虚拟网口被使能 使用usb线连接Zero和PC，在Zero和PC上查看网络接口： ~~~ 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 ~~~ 确认有usb0接口后，手工设置两者在同一网段下： ~~~ 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 ...
