OK. "normal install". You may have been bitten by "normal". Even if
you don't use the GUI tool, if its installed, it will hijack your
attempts to not use them.
Do you have Gnome, KDE, or some other DTE installed? Do you have
something called "Network Manager" installed?
If this is true, this may be your problem.
Can you use Aptitude interactively (i.e. from its text user interface)?
I'll tell you how I do an install then you'll know where I'm coming from
with my suggestions:
I do a base install only, i.e. when the installer tells me to
select what tasks to install, I deselect all tasks.
I then fire up aptitude, tell it to _not_ treat "recommends" as
strong dependancies, then go down the list of installed packages
and ensure that anything which I don't want specifically
installed is either marked as "automatic" or is marked for
removal. I then "g"o with that.
Then I install the basic packages I do want: mc, lynx, vim, man
pages, pinfo, less, HOWTOs, etc. In my case, I'm on dialup so I
also add ppp and pppconfig and the resolvconf package.
Then I set up networking using the standard text files in /etc.
The installer will have set the basics up anyway. My NIC will
be eth0 with IP, netmask, etc. My main box is my nameserver
(with the dnsmasq package) and ppp updates that via the
resolvconf package.
So, if you have any desktop environments installed, I would go through
aptitude and pull out anything related to a GUI networking tool.
If necessary, pull out everything that is not basic. Since you
installed from CD without networking, you'll still have the packages.
I'd even go so far as to ensure that you have a backup of /etc/ before
you start then purge everything you remove. You want to get the box
back to base plus a text editor, lynx, mc, ...
At this point, you can then work with just the /etc/network/interfaces
file.
Here are my network config files which I hope may be of some use.
Let us know how things go once you get rid of the GUI network config
stuff.

There's a file /etc/networks and I note that it has a link-local of
