This can be done at home. I'm running a Linux 2.6 kernel on a Freescale Coldfire setup w/ two FECs, boa to visualize the results, ssh, and a somewhat (still) flaky packet sniffer that is getting closer everyday to working. You can see more details about this on my website: http://www.dtool.com. This is not a commercial product (yet) Best, Tom PS.

I have ordered a few hardware keyloggers to play with (http://www.keelog.com/) and I was wondering if the same idea exists for networks? A device that you could tape under a desk, and that would act as a transparant bridge, sniffing all traffic. I know that you can use arp-spoofing to get a similar result (easier, better?), and I know about hardware network taps. But I'm still interested in the theoretical possibilities of this idea. I have a few old laptops, but these have just one PCMCIA network card, so bridging is not possible (well, with the right kind of network cards you can get two in that slot - I'll see if you can still buy them). But laptops are too big and heavy. I've looked at microcontrollers with ethernet adapters, but here I find webserver appliances with just one network interface. They're small but I'm not sure if you could run an OS and a sniffer on them. I've looked at miniboards but they are very expensive, too expensive for "just a toy". But, considering that you can get a 2-cigarette-pack sized Pix-firewall, such hardware must exist. But I haven't found the right keywords yet. Any ideas? Greetings, Petr Kazil
This looks like the answer to your question - I can't really imagine anything smaller! http://www.arxceo.com/ And http://linuxdevices.com/news/NS2860172381.html The Yoggie will supposedly also support an SDIO wireless card, so you can bridge and snoop AND get remote access at the same time.
