[CentOS] Affordable KVM over IP switch

The D-Links are NOT suitable for professional use. I used one of their 
models and it hanged on me multiple times. Because it is powered by the 
keyboard/mouse/video connectors, the only way to recover it is to 
physically disconnect ALL cables and reconnect them again. As long as 
ONE of the sources of power is connected, the unit won't recover. 
Someday you quickly need to access a machine only to suddenly discover 
that you are stuck and can go nowhere. A real PITA!
