Changing IP

[Jesse Ackerman <jackx135@yahoo.com>]

Hello:

I am installing Debian for the first time. I am trying
to reset the IP address (static) from the install
default.

command: ifconfig 172.21.xxx.xxx
gives me the following error:
     "fetching interface information: Device not   
found."
I thought I changed the IP last night but apperntly
not. an ifconfig -a does not show me the address I
used.

I did a whereis ip found the location but have been
denied permission to open and view the file.

How do I change the IP? or what do you see as the problem
