Project Description: Bash Linux Script...WRT54GL Router...LED Control...

3 print servers will be Totally Ignored.

A Blinking Amber Cisco LED will indicate that 1 or more of 4 cameras are accessing the router while nothing else is.

A Steady Amber Cisco LED will indicate that a client other than or in addition to a camera is accessing the router.

A Steady White Cisco LED will indicate there is activity by these other clients.

A Dark Cisco LED will indicate that no client is accessing the router.
