ifconfig takes the name of an ethernet interface (eth0, eth1 and the
like) and after that the IP address. You might try
# ifconfig eth0 172.21.xxx.xxx
(The # at the beginning is there to tell you that you need to be root to
do that, don't type it.)
Buw beware: ifconfig will not save your network settings. They'll be
lost upon reboot. There are scripts executed at bootup (so called init
scripts, look at /etc/init.d - but better don't touch) and one of them
is called "networking". It reads the network settings from the file
/etc/network/interfaces and configures your devices accordingly.
The "interfaces" file is really simple. Just changing the IP address
shouldn't be a problem as long as you know which device you want to
handle. Mine looks like this:
|auto lo
|iface lo inet loopback
|
|auto eth0
|iface eth0 inet static
| address 192.168.1.2
| network 192.168.1.0
| netmask 255.255.255.0
| gateway 192.168.1.1
The "auto" stanzas tell the networking init script to make the devices
functional during boot. Don't remove the "lo" interface or you'll have
more or less severe problems.

And what does it show?

You probably need to be root (type 'su' in a console or xterm).
Maybe you want to read some User Manual. Take a look at
http://www.debian.org/doc/ and you'll find plenty of it (most of them,
are quite old, though) in many languages.
