Please help me setup Local Area Network. I cannot ping Windows XP host from Ubuntu 9


Hi, complete noob here. I need a helping hand with a Local Area Network that I am planning to put up.

Details:

Equipment:

1. CNet Network Switch
2. UTP CAT5 Ethernet Cables
3. RJ45
4. Ethernet Cards for each host

Operating Systems:

1. 2x Windows XP
2. 1x Ubuntu 9.04

Diagram:

Objective:

1. ping each host to check connectivity
a. Ubuntu ping Windows
b. Windows ping Ubuntu
c. Windows ping Windows

2. Share Files
3. Play Network Games
4. Internet Access for the 3 hosts

Yet More Details:

1. I've set all of the hardware up
2. Windows hosts can ping other Windows Hosts - NOT UBUNTU

PROBLEM:

1. CONNECTIVITY

a. Ubuntu cannot ping other Windows hosts - Therefore NO CONNECTIVITY
Since I run dual boot.
b. I have not tried pinging Ubuntu from Windows XP yet
c. When I boot into Windows I CAN PING other Windows hosts

So my problem is 1.a. I have disabled the firewall of both Host 3 (Ubuntu) and Host 2 (Windows XP). I still cannot ping.



Diagnostics:

1. ifconfig

Code:
ifconfig
eth0      Link encap:Ethernet  HWaddr 00:02:44:43:b1:78  
          inet6 addr: fe80::202:44ff:fe43:b178/64 Scope:Link

2. netstat -rn

3. ping IP

Code:
ping 169.254.204.222
PING 169.254.204.222 (169.254.204.222) 56(84) bytes of data.

From the output of ifconfig, it appears that the eth0 card is only running IPv6 (see line 2). The rest of your network is probably IPv4.
Unfortunately I don't know Ubuntu, so I can't help much further.
On my system I'd be looking at

/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0

but I'm not 100% sure that's where they are on Ubuntu.
