Make sure all three have the same /etc/network/interfaces file apart from
the static IP address which is on your piece of paper on the wall.  All
this typing ifconfig commands is for the birds and a definite source of
errors.  Mine is below between the two lines of --s

---------------------------------------
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
	address 192.168.1.4
	netmask 255.255.255.0
	gateway 192.168.1.1

---------------------------------------

Make it look similar to this one above, apart from each machine having a
different address line which'll probably be 192.168.0.25 etc. and the
gateway line which should be 192.168.0.1.

Then make sure /etc/resolv.conf is the same on all machines.  You can do
this using rsync e.g. on hafren

	rsync -av tren:/etc/hosts /etc/hosts
	rsync -av tren:/etc/resolv.conf /etc/resolv.conf

Of course, you'll need to apt-get rsync.
