Hi, Zeus.
Yes, all the instructions baffle me as well! I'm a total newbie to networking but I've managed to set-up a network of sorts. I can only tell you what I did and hope it helps:
Okay, I network my XP laptop with my Ubuntu installation on my Desktop PC. Firstly, I run XP's Network Set-UP Wizard from the XP laptop, turning on the printer beforehand that is hooked up to the Desktop. At the end of the Network Set-UP Wizard, it will ask you if you want to run the wizard on another computer (in my case, this would be the Desktop running Ubuntu). Answer 'NO' and close the wizard.
I would next, go into Ubuntu on the Desktop and open up 'Sharing' and pick the Ubuntu folders I want to share with the laptop running XP. Electing to use Samba (which enables file sharing with Windows machines).
Next, you need to set-up a 'Samba' password and username. You do this by opening up a terminal from the Ubuntu desktop. Type: sudo smbpasswd -a ***** (where ***** will be the the username you use on Ubuntu. For example: I would type sudo smbpasswd -a david
you will be prompted for your password – again, this will be your Ubuntu log-on password. You then get the option to create a new 'Samba password'. Enter which ever password you want to use – I used my Ubuntu log-on password, but you can use any password (just remember it!).
Next, go to your machine that is running XP and go to 'My Network Places'. Go to Ubuntu server and double click on it. You will be prompted for a username and password (In my case, again this would be 'david = username, then my password would be my Ubuntu log-on password, So, 'password' = what I use to log- on to Ubuntu with.
Having done all this, I should now be able to access my nominated Ubuntu folders from my laptop and share the printer which is hooked-up to the Ubuntu desktop PC (which I can!).
Having said all that, I still can't access my XP laptop's folders from the Ubuntu desktop PC. However, I can send files between the 2 machines through using The Ubuntu server, which will show up on both the XP laptop and the Ubuntu desktop PC. It's a bit of a 'dog's breakfast' as far as networking goes, but at least you could say, I have half a network, which is better than none!
It seems to be an 'access permissions' issue with not being able to access the XP laptop's folders from the Ubuntu desktop PC, but I've tried many ways to correct this, but I'm drawing blanks all the time.
Anyway, I hope this has been of some help to you.
David.
