    Now, I cannot access the local network and the
    internet from the machine. The eth0 device was
    assigned an IP according to its MAC address and now it
    does not work, it says that it is active. When I shut
    down the machine it gave me some weird message which I
    do not know how to get since I am sending this email
    from the other machine which has internet access in my
    classroom.
    Is there a way to solve this issue?

    TIA

    Antonio
