View source for Beaglebone Black - Internet Over USB

__NOTOC__
* Beaglebone board can communicate to the internet over USB cable by sharing your PC's internet connection
* You need not use a separate Ethernet cable to connect your board to internet
* The required drivers are enabled by default in the kernel and loaded when Linux boots on the BBB.
* But you must enable internet sharing on your HOST

=== Target Settings ===
# Add name server address in: /etc/resolv.conf
#: nameserver 8.8.8.8
#: nameserver 8.8.4.4
#  Add name server address in: /etc/network/interfaces
#: iface usb0 inet static
#: 	address 192.168.7.2
#: 	netmask 255.255.255.252
#: 	network 192.168.7.0
#: 	gateway 192.178.7.1
#: 	dns-nameservers 8.8.8.8
#: 	dns-nameservers 8.8.4.4
# Add default gateway address by running the below command
#: sudo route add default gw 192.168.7.1 (Using PC as default gateway) 
#: Run the above command every time you reboot your BBB

=== HOST machine ===
* create usb.sh script file and add the following lines and save it
*: iptables --table nat --append POSTROUTING --out-interface '''wlp3s0''' -j MASQUERADE
*: iptables --append FORWARD --in-interface '''wlp3s0''' -j ACCEPT
*: echo 1 > /proc/sys/net/ipv4/ip_forward

Run this script file every time you reboot/start your Host
