schön,
daß 2 User geantwortet haben, die sich mit sowas auskennen :))
Ohne meine eigentliche Fragestellung selbst noch weiter ins Abseits bringen zu wollen, aber... falls jemand die
Gibson/ShieldsUp Seite noch nicht kennt, empfehle ich dort den eigenen PC einem Sicherheitstest zu unterziehen, das Ergebnis sollte vielleicht doch am besten so aussehen:
Your Internet port 139 does not appear to exist!
One or more ports on this system are operating in FULL STEALTH MODE! Standard Internet behavior requires port connection attempts to be answered with a success or refusal response. Therefore, only an attempt to connect to a nonexistent computer results in no response of either kind. But YOUR computer has DELIBERATELY CHOSEN NOT TO RESPOND (that's very cool!) which represents advanced computer and port stealthing capabilities. A machine configured in this fashion is well hardened to Internet NetBIOS attack and intrusion.
Unable to connect with NetBIOS to your computer.
All attempts to get any information from your computer have FAILED. (This is very uncommon for a Windows networking-based PC.) Relative to vulnerabilities from Windows networking, this computer appears to be VERY SECURE since it is NOT exposing ANY of its internal NetBIOS networking protocol over the Internet.
Your system has achieved a perfect "TruStealth" rating. Not a single packet — solicited or otherwise — was received from your system as a result of our security probing tests. Your system ignored and refused to reply to repeated Pings (ICMP Echo Requests). From the standpoint of the passing probes of any hacker, this machine does not exist on the Internet. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system wisely remained silent in every way. Very nice.

Den Test habe ich heute nachmittag auf Arbeit mit meinem W98SE-PC gemacht, das Ergebnis mag meine Bemühungen, das System mit für W98SE so typischen, wie wirkungsvollen Netzwerk-Mitteln abzudichten, direkt bestätigen. Mit XP, plus den üblichen, empfohlenen Sicherheitsfeatures (ich möchte jetzt keine bekannten Markenhersteller nennen), verhält sich dagegen der Rechner eines Kollegen wie das berüchtigte offene Scheunentor - trotz aller Bemühungen, das zu ändern (Natürlich (be)deutet der Test noch nicht alles (an), aber immerhin..)
