I am currently trying to set up a LAN network b/w 2 ubuntu laptops, using 10.10 and 12.04. How should I do it? Please give detailed steps and such, as I am a complete novice to Ubuntu. And it requires to be done only on Ubuntu and not W7. Hence I'm not using it. Also, after this, I will expand to include 5 computers all running on Ubuntu 12.10. How should I go about it??
