Massimo, he say he want to share a Internet connection of one PC to other PC of her home.
it's is easy, active ip_forward and set the correct iptables to have NAT on the PC that has got Internet.

poseidon@poseidon-desktop:~$ ifconfig eth1 192.168.0.1
SIOCSIFADDR: Permission denied
SIOCSIFFLAGS: Permission denied

I recieve this msg.

with sudo:
sudo ifconfig eth1 192.168.0.1
it will ask you for your password.

What sudo is? And how i can download and install it? I can't find it in Add/Remove

sudo is a command to use root (SuperUser) privileges.
you must put the last command on terminal like that:

poseidon@poseidon-desktop:~$ sudo ifconfig eth1 192.168.0.1

Then, the permission denied don't go out and do that you want.

and i should use sudo before every command?

You should use "sudo" before every command of that guide , and others guides when the prompt of command line finish on #

Example:

this is a prompt.
user@host patch $
----> it haven't administrative privileges.

user@host path # iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE
--> You must use sudo to execute it . THIS DON'T RUN
you may use some like that:
user@host path $ sudo iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE

user @host path $ cat .bashrc
---> You don't use sudo.

"sudo" is only for administrative things.
