Is it possible to disable the power key or to make the program it calls only executable by a SuperUser? Thanks, Brendan McNichols mcnichol@rodan.acs.syr.edu

There is no way to secure the machine if someone has physical access to it... The PowerKeyDisabled thing just protects users from turning off the machine by accident, which is really the best you can do. Mike

That's only useful if you put the machine in a box and hardwire it with conduit (electrical plumbing) so that the badguy can't reach around and pull out the plug instead. At least the NeXT power-off key does a clean shutdown. In general, you have no security unless you first have physical security. -- "Any sufficiently advanced technology is indistinguishable from a rigged demo." ------------------------------------------------------------------------------- Brian Bartholomew UUCP: ...gatech!uflorida!beach.cis.ufl.edu!bb University of Florida Internet: bb@math.ufl.edu
