The OP did not give us that information. I have several devices on my network without user interfaces, like a TV tuner. It has no input device -- I don't think it even has a power switch. I has three wires going in the back -- power, antenna, network. Exactly how am I going to ask it ifconfig? Even a router or firewall can be a mystery as to what IP address it will respond to. Read carefully, and don't impose your network on the OP's situation. Ted Miller Elkhart, IN, USA
