Sharing an XP net connection with a Ubuntu box

uncle-c · 11-06-2007, 06:02 AM

I'm trying to share my XP net connection with a Ubuntu box.
The 2 machines are linked via a crossover patch cable and I can ping / SSH into the Ubuntu from XP with no problems.
Just got a second NIC for the XP box so I want to share the net connection.
the IP of the Ubuntu box is 192.168.0.1 and I've read that if Internet Connection Sharing is enabled on the XP machine, the latter gets assigned that address, so I will have to reconfigure the Ubuntu to have address 192.168.0.2. Also DHCP needs to be setup on Ubuntu. Is this a simple matter of editing the /etc/network/interfaces file or does additional software need to be installed ? I'm running Ubuntu server 7.04. What adjustments would I have to make ?
If a successful net connection is achieved, how safe / secure would the Ubuntu box be ? Would any additional security measures be advisable on the Ubuntu end ?

Thanks again !

Thanks a lot for the reply BD. I have Ubuntu server 7.04 running as the linux box and with no X, so everything has to be done via command line.
The IP of the Ubuntu box was 192.168.0.1, but I had to alter this because when ICS is enabled on XP the XP Box automatically assigns that to itself.

Ubuntu Box :

Code:

 
 # ifconfig eth0 192.168.0.2 netmask 255.255.255.0 up

I also altered my /etc/network interfaces file

# The primary network interface

Code:

auto eth0
iface eth0 inet dhcp (replaced static )
address 192.168.0.2
netmask 255.255.255.0
gateway 192.168.0.1

When I go into windows to set the "Network Connections" the NIC which is connected to the net
I allow to "obtain address automatically" but should I fill in any other fields ?
The NIC which is connected to the Linux box I am unsure of. Should I set it's IP address as 192.168.0.1, netmask 255.255.255.0.
The ultimate goal is to logon to my Ubuntu box from XP using Putty SSH and then use the ICS facility to use wget to d/l files and the "apt-get" install features to install software on my Ubuntu box.

Thanks,
Uncle
