Very Computer

    I have installed Slackware Linux 3.0 on my PC.  I would like to diable
the "Ctrl-Alt-Del" from normal users to prevent them from rebooting, though
it will reboot the system nicely.  Is there any way to do this?  Any
suggestion is highly appreciated.

    Regards,

Comment the ctlaltdel line from your /etc/inittab.

But does this work with "Ctrl-Alt-Del"?

When Ctrl-Alt-Del is depressed, init (process id=1) will spawn a child
which  executes 'reboot'.  So, the 'reboot'   process is run with root
permissions!

To  disable the 3-finger-salute completely,   just comment the line in
/etc/inittab which contains the reboot command.   I have no methods to
disable it for just a group of users.

I haven't found anything in the man page about that file.  Could you please
point me into the direction where I can find any info?

Disregard that posting - I had an old manpage (d*** "preformat" man pages of
Slackware!).

Look through /etc/inittab.  There's a line which tells it what to do
with ctrl-alt-del, and you can just comment that out.

Of course, even as root, you'll then have to explicitly type
shutdown -r now (or whatever) rather than use the deathgrip.
