Thank's to my beloved mother, my family and to the doctors.

NOTE: You are invited to write some start-up scripts for others distributions as ubuntu, because i think the programm have not to be adapt himself.

How does it work ?

datetime-lock must be first configurated throught the different available command-line options, giving multiple ways to set:

-A start date and a start time. -An end date and an end time.

Or with the regular date settings to set as:

-A or some specific days of week like:

--today                                                                 
--weekend-days (saturday and sunday).                                   
--week-days (monday, thuesday, wednesday, thursday and friday.)         
--days (The selected days from the weekdays list.) 

During this time, slice your system is protected against some physical present offender with bad intentions, like cracking your password, even if he does not know it before the violation of your home, your workplace or where ever your system is located.

After datetime-lock configuration the programm print a summary with the currently settings.

!!! The programm does not ask for any confirmation: if you make an mistake

during the configuration, you will see it in the clear printed summary;

if you want to reset the settings do not block the system with an error way you must call the --disable option who will reset the configuration so that your system is not locked with datetime-lock.

Anyway else the locking is now activated and your system is untouchable for the configurated time slice.

The locking mechanism is an automatic directly shutdown process who will prevent from bad intentions intruder, to tip the password, even if he knows it, because the system will automatically shutdown by booting.

In addition datetime-lock log system attemps which you can read with the --display-logs options.

Note: take care by the special time setting midnight because midnight is the first time from the current day.

datetime-config

datetime-config is an little utility to help an regular configuration of datetime-lock in case of an automatic configuration with cron, useable with the substitution command:

$ $(datetime-config -s) # per example                                        

Who support following options:

-s              [start]                                                
-d  hh:mm:ss    [date]                                                 
-t  hh:mm:ss    [time]

Advices

If you are a "security paranoid" like me I can give you the following advices who are not often used:

• Setting an password for the BIOS.
• Disable the CD-ROM | USB booting options in the BIOS.
• Set an padlock on your computer if it is possible, look if the are empty round pin on the computer opening mechanism, in addition or for the open box security.
• If you have an key protected box where to set the computer in, with all for the air set your computer in or by you an adapted furniture.
