Hi, Yes I have noticed this too. You can scan one IP address multiple times and get five different operating systems. Really interested to know the cause of this. Ray ------Original Message------ From: Ryan Giobbi Sender: nmap-dev-bounces () insecure org To: nmap-dev () insecure org Subject: nmap OS detection providing different results Sent: 2 Apr 2011 2:33 PM Hello, When running against non-Windows hosts (AIX), I've noticed that nmap's OS detection (nmap -O) doesn't provide the same results all of the time. About 1/5 scans nmap fails to find the remote hosts when run repeatedly. Is this expected? Would pasting the OS signature that returns when the current ones fail into nmap-os-db and submitting to nmap.org be a reasonable workaround?
