right and wrong. Not a routing problem, an interface configuration
problem. see below.

bingo! this is the root of your problems. The rest is a help message
from the route command

There's a pearl of advice

well, I would check FIRST your netmask. It looks wrong. I think you want
255.255.255.0

uh, only if his eth0 is connected to the internet, and with an ip of
192.168.x.x, unless there was some big ipv4 oberhaul, there isn't going
to be a problem.

Generally, you set up your ethernet on a class C.

IP: 192.168.1.x
MASK: 255.255.255.0
broadcast: 192.168.1.255
netowrk: 192.168.1.0

(generally, these days you do not need to supply the last two arguments,
the tools can figure it out)


and then, when it comes to the internet, you need to worry about default
gateways, and extra interfaces and stuff ( you haven't mentioned how
this is setup for you)

Also, it looks as if linuxconf (shudder) is trying to get a DHCP address
for you. If you are on a network with a DHCP server, this is good. If
not tell linuxconf not to use DHCP or BOOTP.

good luck,
Jake
