Pamela
Pamela is a tool to visualize the "crowdedness" on your network online. We (Hackerspace Brussels) want it so members living far away can have an idea on how crowded the space is before jumping in their cars and driving an hour to get there.
Pamela is made up out of an arp-scanner script that people in run on computers on the network of interest, which uploads the mac addresses in that network (lan) on a webserver.
On the server there is a webpage that does the visualization of the mac addresses present.
Multiple people on multiple lans can run pamela together against the same target web server, which will aggregate all results. This makes it possible to get an overview of multiple lans in the same space.
