IP-Tools. Need to figure out what's on my network. I should have written it down but I forgot. Here's a tool that will scan for me. Here are some utilities:
* "SoftPerfect Network Scanner":http://www.softperfect.com/products/networkscanner/. A high google hit. Freeware and seems fast too for finding systems.
* "WinPCap":http://winpcap.polito.it/. Free network analyzer on Windows. Watch the traffic fly by.
* "NMap':http://www.insecure.org/. A super well known port scanner and security tool. Only a command line version available on Windows, but is also on Unix and Linux with X-Windows interface.
