I have 2 PCs. One of them is using WinXP and the other has Ubuntu 6.10.

The 1st one has wireless internet connection through a router and the 2nd one is connected to the 1st via ethernet.

I have no idea of how to manage to have an internet connection with Ubuntu using the 1st PC's internet connection. I also have no idea of how to share files with Ubuntu and WinXP.

Any ideas of how to do these things? Are these possible to happen? I am a newbie

Thanks in advance

Have you tried pluging the 2nd one into the router ( assuming it has multiple ethernet ports). Could you tell us a little bit more about your router?

Your not very specific in your description. If I understand correctly the 1st one is the Windows XP computer that has wireless card and the 2nd PC is running Ubuntu. The two PCs are connected together via a crossover ethernet cable.

You will need to configure the XP for internet connection sharing (ICS). Googling for ICS will pop up lots of information. Setting the Ubuntu box for an internet connection using DHCP is all you need to do. There are a few snags. ICS automatically configures the network interface IP address 192.168.0.1 and turns on a DHCP server which can not be changed. You might need to change your wireless router setup if it uses the same network (i.e 192.168.0.x).

To share files between windows and linux you will need to configure samba and any firewalls to allow smb traffic.

The router is a US Robotics 9108. I don't want to plug in the 2nd one (Ubuntu) because I need the PC to stay next to the 1st one (Windows) which is a bit far from the router. But I believe that if I connect using ethernet there will be no problem. I have tried that before with an other PC and I found no problem.

@michaelk

You understood correctly. I have created using ICS a LAN connection (IP adress is 192.168.1.8) and Ubuntu (using DHCP) receives packets. The internet connection of the 1st PC is provided by a LAN so I don't think I can change anything without affecting the LAN. But I have no internet connection.
I made this post in order not to google but I guess I have no other option but to google.

Any other idea is very welcomed!!!

Unless you fully explain your problems and what you have already done it is difficult to provide precise answers.

Does the Ubuntu ethernet device get a valid IP address?
Can you ping the windows PC from Ubuntu?
Does the /etc/resolv.conf file contain valild DNS information compared to the windows box?

Let's say that I haven't done anything yet. Theoritically what do I have to do exactly to connect Ubuntu to winXP without any internet connection?

By the way the IP information is
protocol: IPv4
Ip Address: fe80::20a:48ff:fe19:4ac7
Netmask/Prefix: 64
Broadcast: (Blank)
Scope: Link

Any Interface Information is not available.
I have no idea of how to ping...
The path you mentioned doesn't exist.

I just managed to share my files between the PCs but unfortunatelly there is no internet connection. I tried configuring Firefox but without any good result. I have established a connection to WinXP that provides internet to other computers from my wireless internet connection. So I believe this part is ok.

I have no idea of what I should configure in Ubuntu. Please help!!!

by default the IP address should be 192.168.0.1 on the XP when you configure it rite? try ipconfig/all u might have located the wrong ip(wireless?) reconfigure ICS, find out the IP of the network card, on the ubuntu set the ip to be in the same network eg. xp 192.168.0.1 then ubuntu should be 192.168.0.2(subnet mask 255.255.255.0). something like this. then the gateway & dns you set it as the XP ip that you found out.(this is the harder way if your dhcp settings wouldn't work)
