How Nping works at the OS/ kernel level

[Subhra Das <subhradas () gmail com>]

Hi,

I carried out the below experiment. Could anyone help me to find out which
process (at user/ kernel level) on the remote node is responding to nping
TCP packets. Is there any flow diagram to understand the same

a) On Node 1 installed nping tool

b) On Node 2 removed nping tool

c) Executed the *below* command on Node 1. It still works. Could you please
let us know how should we go about finding which process is responding to
nping tcp packets on Node 2, which doesn’t have the nping module installed

*nping -c 1 --tcp -p 13567 <IP Address on Node 2>*
