If you are on a LAN and wish to find out which computers in it
currently have access to that certain LAN,
you can use the following command:
for ip in $(seq 1 254); do ping -c 1 192.168.1.$ip>/dev/null; [ $? -eq
0 ] && echo ?192.168.1.$ip UP? || : ; done
This will ping each computer on the 192.168.1.x subnet one time, with
a one second interval between pings.
The output should be something like
192.168.1.1 UP
192.168.1.17 UP
192.168.1.24 UP
?
Alternatively, you can use netdiscover:
sudo apt-get install netdiscover
netdiscover -r 192.168.1.0/24
This will scan all the computers in that particular address range and
present the active ones
in a table that also provides a MAC address and a MAC Vendor line.
