HI
I am new to python and am having trouble coming up with a script that
idenifies all the live hosts on my network.
thanks Hunter

We acknowledge your problems with a network script idenifying live hosts
on your network.

Seriously, you have to tell us a little bit more so that we can help
you. How about you actually post the script, and actually post the
trouble (What exactly do you expect? What exactly do you see? What other
steps have you tried?)

First you need to define what constitutes a "live host".

I've done this in the past with the great help of nmap:

# nmap -sP 192.168.0.0/23

this will find hosts "alive" from 192.168.0.1 to 192.168.1.254

From python, you can use it by saving it's output to a file and then
reading or with the help of os.popen.


In this case, "alive" means that the hosts with the ip being analyzed
responds to ARPs. see the manpage for nmap.
