[LUNI] Linksys routers/switches and Comcast Cable

[Stef]

Plug the cable modem Ethernet interface into a hub or one of those
cheap (e.g. Netgear) switches, which behave like hubs for ports
matching speed and duplex, and then plug into one of the ports your
router (I am not sure I understand what you're doing with routerS),
and into another port your linux box (make sure you match the port
speed as the router eth interfacee, to be able to sniff), running
(t)ethereal. Take a look at what's going on, and you'll see what
you'll need to do next.
