What Is Out of Band Management?

The normal way to configure a server is what we would call in band, where i talk to a network eface on the server. And then i log into the server and i start doing things with the server. We call that a soft reboot, where you're asking the operating system to re start. That would be inband control. Most soff ware has an agent that you can run on the system, and if you need to make changes to the system, you can ask that agent to do that work for you. In out of management, there is a back door. It's not exactly like an operating system back door but it's a network access that talks to the mother board
