Greetingz!

The serviceconf command is a GUI command, you have to be running an X session (either locally or remotely) in order to use it. It also typically requires root permissions.
Note that in order to run the command while SSH'd into a remote system you will need;

1) To have an X server on your local system "listening"
2) Have the "DISPLAY=" environment varible set to "DISPLAY=your.ip.address.here:0.0"
3) Use "sudo" to run the serviceconf command.

Have fun!
