If the user has root access or physical access, no.

I guess if he has root access then also its possible..
remember /etc/inittab preventing him from pressing Ctrl + Alt + Del...

or anyway we can stop reboot and poweroff script...for other users ..other than root.

Hard Reboot ....It seems difficult...impossible I guess..

What u say??

Disconnect the power button? but someone could still pull the plug, however, technically speaking I think the poster meant via software only. Which I guess would be possible if you removed the shutdown and reboot commands, then no one could ever shut it off short of cutting the power.

sir I do stand corrected, however, I think we may all agree that one committed to shutting down the system will probably find a way to succeed.
