CentOS - Jan 2006 - way to disable keyboard and mouse ports

Is there a way to disable the keyboard and mouse ports?

I have a machine in a public area running an application
that no-one needs to touch.

However, someone could come up and plug a keyboard in
it and mouse and be logged in as that user (not root).

Is there a way to disable the mouse and keyboard so
only remote ssh connections will control the PC if
changes need to be made.

This would also include any usb device which is fine
and the PS2 keyboard and mouse.

Thanks,

Jerry

Epoxy resin usually prevents plugs being inserted where you don't want them
to
be.

Remember, in UNIX, hardware is _useless_ if it is not bound
to a device used by a service.

So remove all relevant entries from /etc/inittab.
The mingetty tty entries, Xdm, the keyboard combination
traps, etc...
Don't start gpm, kudzu, etc... as services either, just to be
sure.

That will prevent any use of a keyboard/mouse once Linux
boots.

You can even remove any prompt from the bootloader.
You can also pass a parameter to set the console to a
physically non-existant COM device, or some other dummy port.

Again, hardware is _useless_ if it's not bound to a device
which is used by a service.  No local ttys, no local access
-- other than the console, which can be set to dummy  ;->

Again, hadware is useless if it's not bound to a device which
is used by a service.

There are also games you can play with /dev and udev too.
