List Of Reachable Machines in the Lan

[bharathwaj_spidy]

how to know the number of reachable machines in the lan from my computer(not who command as it gives only users who are logged in)

you could use nmap for something like this.

Lets take for example the network number 192.168.0.0 with subnet 255.255.255.0

You can run:

nmap -sP 192.168.0.0/24

and this will return all the ip's in that network and subnet that respond to a ping packet (most computers). That's probably the simplest way of doing something like that.
