configuration of the testbed

# all the machines should be upgraded to ubuntu 10.04 #

PRE INSTALLATION
----------------
- note down the ip address of the eth0 interface

INSTALLING UBUNTU
-----------------
- use the 10.04 ISO image from the CD
- make sure the Fedora 4 partition is formatted and wiped out
- use the username: lili, password: interference-
    - for instance, if m/c name: ut-mesh-d-14.csres.utexas.edu; then password: interference-d14
                    if m/c name: ut-mesh-14.csres.utexas.edu; then password: interference-14

A. Configuring the network interfaces

- /etc/network/interfaces: add the entry

auto eth0
iface eth0 inet static
address
gateway 128.83.141.1
netmask 255.255.255.0
