John, I would use "--packet-trace" or tcpdump in order to get a better understanding which probes nmap does. In addition, please pay attention that most of the domain names you specified resolved to multiple IP addresses. regards, martin 2011/8/5 John Hunter <johnny.h.hunter () gmail com>:
I was running the command nmap -sP -PE -R -v microsoft.com ebay.com yahoo.com \google.com slashdot.orgit behaves differently when I was a root user and a non-root user. ironically that when I was a non-root, the result is more accurate. when I was a non-root: john@virtual-evolution:~$ nmap -sP -PE -R -v microsoft.com ebay.com yahoo.com \google.com slashdot.org.... Host 207.46.232.182 is up (0.014s latency). Host pages.ebay.com (66.211.160.87) is up (0.086s latency). Host ir1.fp.vip.ac4.yahoo.com (67.195.160.76) is up (0.016s latency). Host vw-in-f147.1e100.net (74.125.113.147) is up (0.028s latency). Host slashdot.org (216.34.181.45) is up (0.038s latency). Nmap done: 5 IP addresses (5 hosts up) scanned in 13.36 seconds when i was a root: root@virtual-evolution:~# nmap -sP -PE -R -v microsoft.com ebay.com yahoo.com google.com slashdot.org ....
