Tell the beagle to use the host as the gateway
.
ssh root
@
$beagleAddr
"/sbin/route add default gw $hostAddr"
||
true
Then, on your host, run the following commands:
host$
chmod +x setDNS.sh
host$
./setDNS.sh
host$
ssh -X root@192.168.7.2
bone#
ping -c2 google.com

This will look up what Domain Name System (DNS) servers your host is using and copy
them to the right place on the Bone. The
ping
command is a quick way to verify your
connection.
Letting the world see your bone: setting up port forwarding
Now your Bone can access the world via the USB port and your host computer, but what
if you have a web server on your Bone that you want to access from the world? The solu-
tion is to use
port forwarding
from your host. Web servers typically listen to port
80
.
First, look up the IP address of your host:
host$
ifconfig
eth0 Link encap:Ethernet HWaddr 00:e0:4e:00:22:51
inet addr:
137.112.41.35
Bcast:137.112.41.255
Mask:255.255.255.0
