Re: Scan for "outsider" Pcs on network

You don't need a username or password!! The legitimate device
attached to the hub keeps the switch port open.

If the cleaner does not have a username and password, sorry,
you do
not have access to the network even with your router.

Terrible analogy (but aren't they always?). Let's try again. I'm
a cleaner in an office. Rather than the $10 hub I splash out and
buy a $30 wireless hub and router. One evening, I unplug a network
printer and attach my router to the network and the printer to the
router.
Stick it under a table or behind a filing cabinet and in most
offices no one will have a clue that it is there. The whole street
now has access to your network and 802.1x won't help you one bit.
How does that fit your analogy?
