if it's that simple to get your linux connected to the www,
then once yuo figure out how to establish whatever your
default/gateway IP gadget is, the rest is cake:

	iface lo inet loopback

	# your local private LAN:
	iface eth0 inet static
		address 192.168.1.1
		# you can use any 192.168.*.* address
		netmask 255.255.255.0
		network 192.168.0.0
		broadcast 192.168.1.255
	# have all your other 192.168.*.* computers use
	# <address> from above as their router/default/gateway

	iface eth1 inet dhcp

	# my static setup:
	#iface eth1 inet static
	#	address 208.33.90.85
	#	netmask 255.255.255.0
	#	network 208.33.90.0
	#	broadcast 208.33.90.255
	#	gateway 208.33.90.84

yep, via /etc/init.d/networking, which calls 'ifup' to
interpret the /etc/network/interfaces file. i think.

good question. maybe someone with brain cells is listening and
will supply an answer. i know you can do 'traceroute' to see the
first hop, but that's awful klutzy to put into a script. there's
gotta be a better way.

isn't it fun tracking down documentation and pointers? :)

/etc/apt/sources.list is the sucker to nail down, and here's how
you do that (at least my potato uses apt-setup nicely):

	apt-setup

[[
if you don't have apt-setup, hopefully you have the original CD
still and can do

	apt-cdrom add

to make sure your CD is apt-friendly, and then

	apt-get install base-config

which contains the apt-setup utility.
