I think removing the default OS may not have helped.

After a number of hours of attempts I now have the Zaurus and my Ubuntu
box pinging each other. The instructions I was using had, last of all,
the following.

ifconfig usb0 netmask up

route add -host usb0

iptables -t nat -F

iptables -t nat -A POSTROUTING -j SNAT -o ethX --to MY_IP

echo 1 > /proc/sys/net/ipv4/ip_forward

I added sudo to the start of the command but got a "permission denied"
message every time on the last (.../ipv4/ip_forward) command.

This would seem to the last hitch (he said hopefully) before I can get
on to the net with the Zaurus.
