with "DJB-like", ie. UCSPI-interfaced servers and clients, there
normally isn't a central configuration file. there's the notion of
"services" coexisting as independant entities. the "canonical way" to
do this would be a directory sym-linked into "/service" containing a
combination of propably "unixserver", "checkpwd" and "shutdown" in
a simple shell script, sitting patiently waiting for "unixclient"
connections from within an application.

with shutdown, one would have to establish some form of authentication
and transmit the credentials to a service suitably constructed (like
using http://cr.yp.to/checkpwd.html).  the setup would resemble a
customary qmail POP-toaster.

what i don't understand about the original posters question is this:
why doesn't he simply make a script incorporating shutdown(8) and
includes it into UDEs readily available menu-system?  that way
unauthorized users would see the menu item fail, but sodo'ers or root
could shutdown the system with a mouse click.

i think the only extension propably needed in UDE would be a special
input mask for credentials, but this could be equally well done using
any password input widget/ program in a script.

i agree.

in that case, the OP should come forward with some specs.
