Driftnet: Watching Your Surfers

This tool puts a network interface into promiscuous mode and looks for image files. Any image files found are displayed as a continuously changing mosaic on the desktop. It has the ability to listen a tond keep mpeg and sound files as well.

On my monitoring server, I have eth1 connected to a switch spanned port which in turn listens on the internal firewall interface. This captures all the media files that users are bringing in from the internet.

Installation is easy:

apt-get install driftnet

To run is even easier:

driftnet -i eth1

Original files are found at Driftnet. This sites has other interesting software such as proxies, mail impersonators, visual formatting, graphics, and more.

I found this little treasure through a where some other nifty monitoring tools can be found.
