How to ping MAC address in Linux

Question

I want to ping a known MAC address, I tried to use nmap:

sudo nmap -sP 192.168.15.1/24 | grep  20:64:32:3F:B1:A9

But in this case its ping all

Answer 1

nmap has the -T option to speed things like this up. -T 5 is the fastest.

You can also try the --min-parallelism option.
