You should look at the networking how-to on
www.tldp.org
Most 8139's use the 8139too module these days. Have you brought the card
up, and added the route/default route?
ifconfig eth0 192.168.?.? netmask 255.255.?.? up
route add -net 192.168.?.? netmask 255.255.?.? eth0
You can run these to verify:
route -n
netstat -r
If you're using a gateway/router this syntax might help?
route add default gw 192.168.?.? eth0
NOTE: the IP's can be anything allocated to a private network. All of
which is discussed in the how-to's. There are other parts to configure
though. Some of which have scripts that are fairly comprehensive. Others
require you to tack on your rocket science degree and get busy.
