demo3a (network configuration working)
demo3a has some consmetic problems, but some fairly interesting functionality.
The nicest thing about demo3a is that that udpkg and cdebconf are working well
enough that other udebs can be installed and debugged/tested.
My machine has two cards, one on a cable modem, one on a 192.168 net. I first
configure the static network and ping a host on it. I then configure the dhcp
side, and ping www.debian.org.
Known Problems:
-proc filesystem isn't working, so I can't find the network interfaces
automatically.
-netkit-tiny's ifconfig didn't work for me, so I pulled in the standard one.
-some of the output from netcfg is messed up, easy to fix, just messed up
Note: debconf and udpkg in this demo include the patches I sent in my
previous post.

Choose the domain name.
As with individual systems, every network has a name. This name is called the
domain name. Please enter your domain name or leave this field empty if you
don't have a domain.

Choose the DNS Server Addresses
Please enter the IP addresses (not host names) of up to 3 name servers,
separated by spaces. Do not use commas. The servers will be queried in the
order in which you enter them. If you don't want to use any name servers just
leave this field blank.

Network Configuration
======================
What is your netmask?
The netmask is used to determine what ipaddresses are valid on this network.
This allows your computer to determine whether or not it needs to send packets
destined for a particular ipaddress to a gateway.

What is your IP gateway address?
A gateway system is one that connects your network to other networks such as
your company wide-area net or the Internet. If there is no gateway in your
subnet just leave this field blank.

What is your dhcp hostname?
In some situations, you may need to supply a DHCP host name. These situations
are rare. Most commonly, it applies to cable modem users. If you are a cable
modem user, you might often need to specify an account number here. Otherwise,
you can just leave this blank.
