Your network is probably:

Network:  192.168.0.0
Netmask: 255.255.255.0
host addresses:  192.168.0.1 - 192.168.0.254
broadcast address:  192.168.0.255

Just issue:

ping -c 10 -b 192.168.0.255  

where -c 10 indicates 10 packets
          -b means allow pinging a broadcast address

192.168.0.255 is your broadcast address

Each host 1-254 will respond if it is on-line.  Simply collect the responses 
and you'll have your list!
