What does route say on your desktop? Also have you added you name server
to /home/etc/resolv.conf on the zaurus? You will also need to
192.168.129.1 as the default gateway on the Z.

With my setup (I only have 1 pc runningi at the moment, but I
occasionally run vmware to test stuff)

desktop usb0 192.168.0.1
zaurus usbd0 192.168.0.201

when I plug in usb cable

on desktop (running gentoo linux)
route add -host 192.168.0.201 usb0

on Z
/sbin/route add default gw 192.168.0.1 usbd0

I also need to enable IP forwarding, but that is done by my firewall
script
echo 1 > /proc/sys/net/ipv4/ip_forward

That gives me access to the internet, and to vmnet when I have vmware
running

Hope this helps

Stu

P.S. you might also want to check out http://www.zaurususergroup.com for
an abundance of info on the Z - although there are a lot of windows
users.
