Java Possible?: Making a program to detect surrounding IPs, remote shutdown/etc.
My father showed me this iPad application that can find surrounding secure connections, plant a remote program or something of that sort into them, and cause the computer to shutdown or restart but display a loading prompt with the option to cancel the restart process if wished. Then I got this epiphany that there must be some way to do the same thing in Java (considering that is what I am currently studying) and to replicate a program of that sort. But leave out the unnecessaries like the GUI. Does anyone have anything that could be of help to achieve this such as starter links or example source code that could do minor versions of the sort?
