It listens for attachment/detachment of input devices (keyboard, mouse, etc.) and informs listening programs of those events. dbus is an interprocess communication system that allows programs to connect to and exchange messages with other programs. It allows the kernel, for example, to interact with your desktop. Rather than you interacting directly with the kernel, dbus acts as a middle man, controlling the communications between the two and only allowing you to perform actions which are considered "safe" or "reasonable". The two work together, for example, to let your desktop know when you connect a new mouse or type on your keyboard. -- Paul Schmehl, Senior Infosec Analyst As if it wasn't already obvious, my opinions are my own and not those of my employer. ******************************************* "It is as useless to argue with those who have renounced the use of reason as to administer medication to the dead."
