nping, a ping for more protocols

Nping is really handy when you suspect that ping or traceroute aren't giving you clear results.  I really like it for a TCP Connect to a website:


$ nping --tcp-connect -c 3 --delay 2s www.google.com

You can also scan MAC addresses on your local subnet:


 $ sudo nping --arp-type ARP 172.16.16.1-10 --count 1
