Here’s a neat article on how to use keyboard LEDs to monitor the status of a linux server. MartyBug.net writes “I have a number of linux servers at home, and typically want to be able to monitor the status of them remotely. The servers are all located in a walk-in-cupboard in my office, and being able to see the status of some key parameters is very handy. In particular, I want to be able to see the status of my internet firewall, a Smoothwall box, ie, if my internet connection is up, and if traffic is being received and/or transmitted“. Link.
