  This isn't that hard of a question to answer. tkined searches for
hosts by using ICMP echo requests. If you're allowing ICMP through the 
firewall, then it'll come up with a map, simple as that. 

  Some of tkined's nicer mapping abilities depend upon whether you're
allowing other types of ICMP packets through or are running SNMP.
