sense no one has mentioned it yet - nmap -sP 192.168.1.*
will get you what you want. now, a nice little trick i used to do on
semi embedded systems that i didn't want to install anything on (emc
darp, and vmware esx):
seq 0 254 | while read f; do ping -c 1 $f; done; arp
you might want to clear your arp cache first though:
ip neigh flush all
... though, something tells me you're not going to be doing any of
this because nmap is the right tool for the job :)
