This ruby script will help discovery live hosts on a network through the use of ICMP. This script is dependent on an installed and running version of nmap. Additionally the script is dependent on the ruby gem netaddr
Define the subnets you would like to scan in CIDR notation only.
root@bt:~# cat subnets.txt 192.168.0.0/24 192.168.1.0/24 192.168.2.0/24 192.168.3.0/24 192.168.4.0/24 192.168.5.0/24 192.168.6.0/24 192.168.7.0/24 192.168.8.0/24
Execute the pingsweep command against the targeted subnets in the file
root@bt:~# ruby pingsweep.rb subnets.txt [+] Running pingsweep scan against 192.168.0.0/24 [+] 8 live hosts in 192.168.0.0/24 [+] Writing live hosts to file: /root/hosts/192.168.0.0_hosts.txt [+] Running pingsweep scan against 192.168.1.0/24 [-] No live hosts in network: 192.168.1.0/24 [+] Running pingsweep scan against 192.168.2.0/24 [-] No live hosts in network: 192.168.2.0/24 [+] Running pingsweep scan against 192.168.3.0/24 [-] No live hosts in network: 192.168.3.0/24 [+] Running pingsweep scan against 192.168.4.0/24 [-] No live hosts in network: 192.168.4.0/24 [+] Running pingsweep scan against 192.168.5.0/24 [-] No live hosts in network: 192.168.5.0/24 [+] Running pingsweep scan against 192.168.6.0/24 [-] No live hosts in network: 192.168.6.0/24 [+] Running pingsweep scan against 192.168.7.0/24 [-] No live hosts in network: 192.168.7.0/24 [+] Running pingsweep scan against 192.168.8.0/24 [-] No live hosts in network: 192.168.8.0/24
The script will output the raw nmap output to the pingsweep directory as shown below:

The script will output the live hosts into the "hosts" folder as shown below. There is only one file in the hosts folder because all other networks did not have any live hosts on the subnet.
root@bt:~# ls -l hosts/ total 4 -rw-r--r-- 1 root root 110 2012-10-02 19:04 192.168.0.0_hosts.txt
View the live hosts:
root@bt:~# cat hosts/192.168.0.0_hosts.txt 192.168.0.1 192.168.0.100 192.168.0.107 192.168.0.108 192.168.0.117 192.168.0.123 192.168.0.130 192.168.0.131
