For example, the BrickHouse doesn't have a telnet daemon, so telneting into the server isn't possible. And because no shell binaries exist, intruders can't get to a root shell. In its role as an appliance, this is a very logical approach, but perhaps taken a little too far. There are features I require as a systems administrator, such as systems for backups and logging. The server as a whole is a plain white box.
Installation is very simple.
After unpacking the system unit, just plug it into the power socket and into your network, and switch it on. You can hook up a monitor to watch the BIOS and boot messages, but there's not much point. I didn't even see any system messages being logged to the screen once it was configured. After it boots, BrickHouse beeps once every five seconds until it has been configured. The beeping lets you know that the system is still in the unconfigured state.
