Hello Grep, Try 'route -en' & you'll notice that a route
for the net 'one u used below' will be pointing at eth0
this was a -large- idea change around 2.1.100+/- . This
is assuming net-tools-1.49 .
Another way is to get Alexey's iproute tools @ :
ftp://ftp.inr.ac.ru/ip-routing/iproute2-current.tar.gz
Also read the README, for any other needed materials .
