In-Reply-To: <[EMAIL PROTECTED]> A great tool that I use for this type of "information gathering" is NMAP. Go to http://www.insecure.org It does a lot more than what you want however it has a simple command that you can use to see if a single port is open on an IP address and you can use other types of "pings" other than ICMP such as ACK and SYN. check it out. There is a windows version available however I don't know if it does command line. You can always install cygwin and emulate a unix/linux box on your windows box... go to http://www.cygwin.com then you can use the cygwin unix emulation command line version of NMAP.
