Pamela is an arp-scanner, it uploads the mac addresses in your local lan on a
|
|
webserver where you get a visual representation of the mac addresses present.
|
|
Multiple people on multiple lans can run pamela together against the same
|
|
server, where all results are agregated. In short, pamela gives you an overview
|
|
of how big the shared network is."
