Thank You.
It works very well!!!
I have only one question:
If I use "sudo bash -l" my system takes an error like "username is not in the sudoers file.....". Where can I found this file? Can I edit this sudoers file and how?
I have found this: http://wl700g.homelinux.net/drupal/?q=node/84
But I dont want to have my username with administrative functions, I want to make it like a normal user. How can I do that?
