How to setup a static ipaddress via the command line in linux

From time to time I need to do some manual network configuration via the command line in Linux.  At one time I would gasp at the thought, with the help of Google I have become very comfortable with command line activity.

Here is a great article from Cybercity.biz.  They go into a lot more detail.  I have put the info below that I used:

Howto: Ubuntu Linux convert DHCP network configuration to static IP configuration

Open network configuration file
$ sudo vi /etc/network/interfacesOR$ sudo nano /etc/network/interfaces
Find and remove dhcp entry:
iface eth0 inet dhcp
Append new network settings:
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

Save and close the file. Restart the network:
$ sudo /etc/init.d/networking restart

Ubuntu 10.10 Install was hanging on the startup screen

I was trying to reinstall Ubuntu 10.10 on my laptop today and it was freezing on the  "Preparing to install Ubuntu" screen.


Turns out it was my 2 USB drives that were plugged in were causing it to freeze.  Once I unplugged the drives, the install starting working.
