No just for information. I seen a post from another person with the same
host name that had attacked them and I get this one at least 2 time a day.
But fortunately I have everything blocked and no one can get acces (
Ihope) So far so good. If it is a dial up then possible a spoof because
I have the same hostname everyday...
