Mixing It Up
Nmap also supports a number of performance and reliability features, such as dynamic
delay time calculations, packet time-out and retransmission, parallel port scanning, and
detection of down hosts via parallel pings. Nmap also offers flexible target and port
specification, decoy scanning, determination of TCP sequence predictability, characteristics,
and output to machine-perusable or human-readable log files.
With that said, you can also mix and match the Nmap options. For example, take a
look at the following syntax:
nmap -v -v -sS -O 172.16.22.1-50
The above syntax will initiate Nmap with maximum output verbosity, in a stealth
mode scan, plus operating system detection on all (live) systems between 172.16.22.1
and 172.16.22.50.
As another example, take a look at the following syntax:
nmap -sS -p 21,80 -oN webservices.log 172.16.22.1-50
Nmap 391
The above syntax will have Nmap search for systems offering the Web services, FTP
and HTTP, in stealth mode between IP addresses 172.16.22.1 and 172. What’s more, the
output will be ported to a log file, webservices.log.
Nmap has become a defacto standard for security auditing, especially with the
newest flavors for Windows and Mac OS X platforms. For more information and
