What exactly is the difference? I ask because I'm also running shorewall, and although I've closed all but a couple ports, I get the following results when running nmap from an outside machine: (The 1527 ports scanned but not shown below are in state: filtered) Port State Service 113/tcp closed auth 139/tcp closed netbios-ssn 445/tcp closed microsoft-ds Interestingly, I need to run 'nmap -PT<port> <ip>', where <port> is one of the ports I've opened, to make nmap realize the host isn't down. Presumably, this is because port 80 is closed -- but why would it, and all others, be reported as "filtered"? -Eamon -- [EMAIL PROTECTED] mailing list
