A script to check ports of a long range of IPs

tirengarfio · 07-06-2009, 04:43 AM

Hi,

i want to create a script that will check the ports of a range of IPs.

I could write all the IPs, but i have thought there is maybe a way to write the rage instead of all the IPs.

Is that true?

Do you advice any language to write this kind of scripts?

Hi,

You could use nmap

Code:

nmap -p 80,22 10.0.0.0/24

Thanks!,

the next question im wondering is:

If i get this result,

Starting Nmap 4.76 ( http://nmap.org ) at 2009-07-06 11:57 CEST
Interesting ports on localhost (127.0.0.1):
PORT STATE SERVICE
80/tcp closed http

then, I would like to write in a log file:

127.0.0.1: 80 CLOSED

How would you do that?

Ciao
