Strange. How old are the network cards that you are
trying to use?? What make are they?

I'd be interested in seeing an output of the command
"ifconfig"...... especially, as you say that you
cannot ping anywhere. Are you using DHCP to pick up
hostnames??? Or are you adding entries in "/etc/hosts"
manually???

I would suspect that the reason you are able to ping
localhost (usually 127.0.0.1/2) is because this has
been set up as a lo (loopback) device. This ping never
reaches another computer, it merely pings itself
internally.

It's your lucky day...I don't drink!! I would say,
that if you posted me a copy of your ifconfig output
results, then maybe I can help you further.

Of course, the other thing to check is the following:

In "/etc/nsswitch.conf", there should be a line:

"hosts:      dns files"

make sure that you add the word all to the list, so
that it looks like the following:

"hosts:      dns files all"

See if that has any effect.

HTH,
