Re: Pinging over a LAN
You want the computer receiving the ping to report to a user that it has been pinged, or do you want the report to come back to the computer that sent the ping?
The easiest method without creating custom scripts and whatnot would be to install Firestarter. It's a free firewall application that has a very simple GUI, and a log tab that will display every incoming connection attempt that you don't have a rule set for, including pings. If you minimize it to the system tray and something happens, its icon will turn into a red lightning bolt to catch your attention and let you know something else is going on.
You could get all fancy with some scripts calling zenity to display a dialog, but I think Firestarter would be faster.
