How to disable Ctrl+Alt+Del restarting in CentOS
In CentOS, the action taken when Ctrl+Alt+Del pressed is based on the configuration file located in "/etc/init/control-alt-delete.conf" Just disable the line which specifies the restart action. vi /etc/init/control-alt-delete.conf comment the line # exec /sbin/shutdown -r now “Control-Alt-Delete pressed” :wq (save and exit) that should do the trick!!! Cheers!!!
