Hi Donald Wayne Chandler!

If it were not for the fact that our little DSL modem's DNS nameserver
will not handle IPv6-DNS queries I would gladly use it's DHCP server
to obtain and set my IP settings.  As it is, setting up a static IP (I
hope my IP never changes it's nameserver addresses) is an easy "fix"
to this problem

"gksu network-admin" is what the "launcher" of "System >Administration
> Networking" is and is what I used to set up my static IP.  Please
note my /etc/network/interfaces file:

tod at tod-desktop:~$ cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface eth0 inet static
address 192.168.X.X
gateway 192.168.X.X

auto eth1
iface eth1 inet dhcp

auto eth2
iface eth2 inet dhcp

auto ath0
iface ath0 inet dhcp

auto wlan0
iface wlan0 inet dhcp

auto eth0
tod at tod-desktop:~$

I have never edited this file!!  The system works fine and comes up
with the network and Internet access active.

When I was in the "Network Settings" window I clicked on the "Ethernet
connection" and then hit the "Properties" button.  In the resulting
"Interface properties" window I checked the "Enable this connection"
box chose "Static IP address" in the "Configuration" drop down and set
up the IP address, subnet mask, and gateway address.   I then hit the
"OK" button and then clicked the DNS tab and then added the DNS
(name)server I found present when I had allowed the DHCP server in our
DSL modem to set up the networking for the box (the one that was not
the box on our NAT'ed net).  You can see the DNS nameserver IP's and
domain names in /etc/resolv.conf.

Here is the result of ifconfig (a few "X"s thrown in for privacy - as above):

tod at tod-desktop:~$ ifconfig
