beaglebone black debian wheezy usb net configuration and ssh login on windows and Linux

settings on BBB

=======/etc/rc.local========

# g_multi has been loaded, if usb is not plugin , it seems not hang the OS
# hotplug get the device when usb is plug in?
sleep 30 # this delay should be longer than LAN eth0 delay?
ifconfig usb0 192.168.7.2 up
#route add default gw 192.168.7.1  #should be set in network/interfaces
echo “setting up usbnet with ip 192.168.7.2”

ifconfig -a >/var/log/netif.txt

============/etc/network/interfaces=============

sudo nano /etc/network/interfaces

#add nameserver for this interface

# Ethernet/RNDIS gadget (g_ether) or g_multi for debian
#worked on ArmStrong on MMC, but not sure for Debian on SD card
# … or on host side, usbnet and random hwaddr,  Linux host side IP should be $
#allow-hotplug usb0
iface usb0 inet static
address 192.168.7.2
netmask 255.255.255.0
network 192.168.7.0
gateway 192.168.7.1
dns-nameservers 192.168.7.1

———–DNS——

/etc/resolv.conf is automatically generated at runtime,

/etc/hosts            add your hostname into this DNS cache file

———debug——-

using LAN or HDMI output to monitoring the setup

lsmod

lsusb

ifconfig
dmesg

debian@EEE-BBB:~$ route

on my PC: (host)

windows 7,

after setting the new NIC ip static as  192.168.7.1,network will automaticall working if USB is plugged in,

Linux should also work

#ifconfig usb0 192.168.7.1  up

now, ssh should works at ip: 192.168.7.2

———————————————–

// config for ip forwarding on host ubuntu.

# iptables --table nat --append POSTROUTING --out-interface wlan0 -j MASQUERADE
# iptables --append FORWARD --in-interface usb0 -j ACCEPT
# echo 1 > /proc/sys/net/ipv4/ip_forward

after that you can ping them pc-> bb and bb-> pc

to acceess internet from bb you need adding name server addr for beaglebone (8.8.8.8) in file /ect/resolve.conf
