yeah, its 5:30am so i have nothing better to do than anything which avoids sleep!
sudo apt-get update && sudo apt-get install nmap etherape && gksudo etherape
This will install nmap and install and run etherape, click Pref. and turn off name resolution in etherape
and in another terminal…
nmap -sP -iR 150 -n
now keep your eye on etherape, 150 nodes will appear and patterns start to form on the lines representing the connections…
note: “nmap -sP -iR 150” instructs nmap to ping 150 random IPs, if you’d rather not be spewing echo requests across the Internet then use “nmap -n -sP 192.168.255.*”
The more nodes you ping the more impressive it becomes…
if your really bored turn on dns resolution (nmap -sP -iR 150 -R) and watch all the dns replies come back in wireshark for the next few minutes after you kill nmap…
