BBB Internet over the USB cable
It is rather easy to get access to the whole internet over the USB interface cable provided that your laptop/PC has internet access.
If you're running Linux you can follow these instructions.
If you're running Windows Derrek Molloy has some advices on this page.
On the BBB create this file and make it executable
#!/bin/bash # # Author : Klaus Kolle # Date : 2016 02 22 # Purpose: Establishing connection to the Internet # and set the clock, which has no battery backup # echo "Starting the Internet-over-USB script" ## Add a default gateway /sbin/route add default gw 192.168.7.1 grep -q 220.127.116.11 /etc/resolv.conf if [ "$?" -ne "0" ]; then echo "nameserver 18.104.22.168" >> /etc/resolv.conf fi ## Test for network availability while : do ping -c 5 -w 10 192.168.7.1 if [ $? -eq 0 ]; then break fi done ## Now we should be ready to set the clock from the net /usr/sbin/ntpdate -b -s -u dk.pool.ntp.org date echo "End of the settings script"
At first login on the BBB execute this script as root (or use sudo).
Automating the script
You may want to set this script up so it will be executed at boot time. In order to do this you'll have to setup a boot script in /etc/init.d - you may want to call it internetOverUSB. Enter ths into the script.
#! /bin/sh ### BEGIN INIT INFO # Provides: InternetOverUSB # Required-Start: $all # Required-Stop: $all # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Enables Internet over USB cable # Description: Enables access to the Internet over the Internet connection # provided by the connected host ### END INIT INFO case "$1" in start) sleep 20 /root/internetOverUSB ;; stop) #no-op ;; *) #no-op ;; esac exit 0
$] chmod 755 /etc/init.d/internetOverUSB
The 20 seconds sleep is for the laptop being able to establish its network settings. May be adjusted to suit your OS an laptop specific needs.
Finally enable the script.
$] update-rc.d internetOverUSB defaults
Try to reboot and login again. Check that the date now is correct. If not debug your scripts.
