I quite like nmap -sO -P0 to identify live hosts:

Host is down:
# nmap -sO -P0 192.168.100.1

Starting Nmap 4.00 ( http://www.insecure.org/nmap/ ) at 2006-03-28 09:17 BST
All 256 scanned ports on 192.168.100.1 are: open|filtered

Host is up:
# nmap -sO -P0 192.168.100.2

Starting Nmap 4.00 ( http://www.insecure.org/nmap/ ) at 2006-03-28 09:19 BST
Interesting protocols on box1 (192.168.100.2):
(The 253 protocols scanned but not shown below are in state: open|filtered)
PROTOCOL STATE    SERVICE
1        open     icmp
6        open     tcp
17       filtered udp

Nmap finished: 1 IP address (1 host up) scanned in 33.960 seconds
