[ILUG] network discovery...

[Gary McCloskey]

Try nmap - give it a host/list range and away it goes, even does OS identification. From the rpm -qi 

"Nmap is a utility for network exploration or security auditing. It supports
ping scanning (determine which hosts are up), many port scanning techniques
(determine what services the hosts are offering), and TCP/IP fingerprinting
(remote host operating system identification). Nmap also offers flexible target
and port specification, decoy scanning, determination of TCP sequence
predictability characteristics, sunRPC scanning, reverse-identd scanning, and
more."

Should be available from http://www.insecure.org/nmap/
