All- # Nmap 5.00 scan initiated Tue Sep 29 10:52:36 2009 as: nmap -6 -sP -iL c:\ipv6.txt -oN c:\Donzi_sP_CLIv6.txt Host 2:0:0:2::1 is up (0.00s latency). Host 2:0:0:3f::fff0 is up (0.37s latency). # Nmap done at Tue Sep 29 10:52:55 2009 -- 20 IP addresses (2 hosts up) scanned in 19.38 seconds It should be noted the output of Donzi subsequent attempts to run the same scan resulted in varying degrees of success. In some cases NMAP reported all 20 hosts, some three, some nine, with no real apparent pattern. According to Wireshark all the same packets are sent with identical responses received per probe. Contrary to the documented default behavior of -sP the packet capture from Donzi's -sP scan shows no ICMP requests, only TCP SYN packets. In cases where the capture shows a host replying with a TCP RST/ACK which should alert NMAP to the host being "up" no such status is reported. -Paul _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
