[Sugar-devel] A network question

[Peter Hewitt]

Not exactly as per your instructions but I think equivalent.

And I assume it should be

sudo ifconfig eth0 10.0.0.1

not

sudo iwconfig eth0 10.0.0.1

Seeing I had an established ad-hoc network I just configured the "bad" 
computer and made sure the "inet addr" line agreed with the other two 
machines on the ad hoc network. I assigned "169.254.7.200" to B. Pinging to 
or from it produced

Destination Host Unreachable.
