You guys should really be posting this on the nmap-hackers/nmap-dev lists. What version of nmap are you running? What OS and patch set? One very key question is are you running any transparent caching proxy servers? If so, your results will be incorrect. Aaron J. Bedra On Mon, 2005-09-12 at 17:19 +0800, cy.wang wrote:

It happens to all machines I scan outside the local area network.
