Hello Linux Gurus,
I have decided to teach myself to use Linux.  I purchased the book “The Ubuntu Beginner’s Guide” and have started reading and working through the examples put forth in the text.  I have just installed Ubuntu server 12.1.  I have configured a static IP on that server.  I did this using the following steps:
1.  Open the interfaces file using the following command:  sudo vi /etc/network/interfaces
2.  I changed/added the following to the file (using vi):
            Iface eth0 inet static
            address 10.0.0.5
            netmask 255.255.255.0
            broadcast 10.0.0.255
            gateway 10.0.0.1
3.  I saved the changes and quit vi.
4.  At the command prompt I typed the following command to have the OS re-read the         config file:  sudo ifup eth0
5.  After running the command above, I receive a message that states interface eth0 is already configured.
6.  When I run ifconfig, I see the IP settings that were pulled from DHCP.
7.  If I run the following command my changes to the interfaces file are reflected when I run ifconfig:
sudo /etc/init.d/networking restart

My question is why didn’t the sudo ifup eth0 force Linux to re-read the config file?

Thanks in advance for your help.

If your eth0 is already up, doing ifup on it does nothing - it doesn't refresh settings.  You can do ifdown first, but networking restart does it nicer anyways.
