Hi everybody! Nessus reports on every scan the security holes mentioned in subject. Even on machines that have been installed minutes before and never had any network-connection. This cannot be true. I had a look on these attack-scrips. They all have a similar structure: 1. Send an UDP-packet to the attacked machine. 2. Look for an UDP-answer 3. If there is an answer, report security hole 'x' else report security hole 'y' But if nothing listens on this port most machines answer with an ICMP unreachable, which the script always ignores. Then there is no answer and it reports an security hole. Maybe someone can fix this? I tried, but I first have to learn NASL ;-) -- Heute ist nicht alle Tage, ich komm' wieder, keine Frage!!! Yours Joerg War is an equal opportunity destroyer.
