I'm having the same problem here. Worse, it doesn't even work if you pass it -P0.
% sudo nmap -P0 -vvvv 10.0.0.71 Starting Nmap 4.20 ( http://insecure.org ) at 2007-03-14 19:34 GMT Initiating ARP Ping Scan at 19:34 Scanning 10.0.0.71 [1 port] Completed ARP Ping Scan at 19:34, 0.22s elapsed (1 total hosts) Nmap finished: 1 IP address (0 hosts up) scanned in 0.334 seconds Raw packets sent: 2 (84B) | Rcvd: 0 (0B) % -- nmap wrongly reports host is blocking ping probes https://launchpad.net/bugs/91004 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
