ksysguard applet: connection settings...?

Hello! I wanted to have a monitoring in the task bar on the hard disk usage of my machine (localhost) and I found out that the ksysguard applet handle should be able to do that. So far so good. I then wanted to set it up. It suggests to drag and drop the sensor into the applet cell. After having done that, it asks for the connection type (ssh, rsh, Deamon, custom). I tried them all but always finish up with a non working sensor (with a small drawing indicating so). The best result I could get was with ssh where I get a message box asking for my password without letting me enter it (there is no filed available). What do I miss? Thanks in advance for your help!
