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.'
