Script to find out different OS on the network

[Aditi gupta]

Hi,

 can anyone guide me in creating a script to find out all the LINUX machines on my network, with ip address.


Or any tool suggested for this.

basically i want to check, how many lInux machines , i have in my network, so that i can prepare a monitoring system for those machines.

We have Ubuntu machines in  our network.

It will be good, if am able to fetch the IP address also(least feasible).

But still we can give a try.


This is really urgent, if some one can guide me , as early as possible.

Thanks in advance.

I've used Advanced LAN Scanner (windows program) for the same thing you need. It doesn't readily tell you which machines are running linux, but you can compare open ports. Linux machines will have different set of opened ports compared to Win machines. It created list by IP addresses. I've used it on /24 networks and reviewed the results manually. If your networks is larger this approach might not be practical.
