Initiating Ping Scan at 07:39 Scanning 64.13.134.52 [2 ports] Packet capture filter (device eth0): dst host 10.40.85.35 and (icmp or ((tcp or udp) and (src host 64.13.134.52))) We got a TCP ping packet back from 64.13.134.52 port 80 (trynum = 0) ultrascan_host_probe_update called for machine 64.13.134.52 state UNKNOWN -> HOST_UP (trynum 0 time: 0) Changing ping technique for 64.13.134.52 to tcp to port 80; flags: A Completed Ping Scan at 07:39, 0.36s elapsed (1 total hosts) So indeed, it does change ping technique. _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
