Re: nmap OS detection providing different results

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.

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?



Thanks

Ryan
