=== message truncated === 

E' quasi sicuramente un tentativo di attacco
effettuato
dal worm Nimda/Code Red. Non preoccuparti perchč
infetta solo sistemi Windows con web server IIS.

Se vuoi saperne di pių segui questo link:

http://www.cert.org/advisories/CA-2001-26.html

Stasera butto gių un scriptino per mandare per mail
i log giornalieri di Apache.

Ciao

Giuseppe
