Get Alive Machine In LAN

TurnToJPG -->


For searching all of the alive machine in the LAN, we could use nmap for searching.
Install the nmap via:

sudo pacman -S nmap

Scan the lan for living host:

# nmap -sP 10.0.0.*

Starting Nmap 6.47 ( http://nmap.org ) at 2014-12-29 14:25 CST
Nmap scan report for www.routerlogin.com (10.0.0.1)
Host is up (0.00040s latency).
MAC Address: xxx.xxx.xxx.xxx(xxx), 
Nmap scan report for 10.0.0.20
Host is up (0.00019s latency).
MAC Address: xxx.xxx.xxx.xxx(xxx), 

Via this command we could easily detect which machine is living in the LAN.
