I have this sun box that needs to be fired up but i don't have a monitor for it. I need to change the ip so we can ssh into it. I hear you can use a laptop as a monitor. I even have a cable that is usb to ps2 to 25 pin female with a 25 pin gender changer which plugs into the back of the sun box. is this correct? do i have to use a program to connect to the sun box? what do i do?
