When you install ubuntu-server, it lets you configure the network, with the option to do that automatically.
My computer wasn't attached at the network at the time, so I just skipped this part.
Now it is attached to the network, but of course, there is no network connection.
How can I let the automatic configuration utility run manually ?
dpkg-reconfigure ifupdown ?
I do NOT want to edit /etc/whatever manually.
I can use google to find something like http://www.iprobot.net/linux-tutorial/how-to-setup-network-interface-card-in-ubuntu/ myself.
Console-only, so no GUI
