Please do not create multiple threads for the same topic. I have merged the threads.

Regarding your problem, you can have a wrapper script that records the date/time and the command that is run before proceeding to run the command (sort of like inetd wrappers) or you can use software like CA's eTrust/SeOS which can be used to track everything that happens on your computer right down to the system call level.

Dear blowtorch,

i'm extremly sorry for sending more than one thread on the same tpoic.
But as you suggested,can you give me some more details about the same or some sample coding?

Thankx,

Google for some of blowtorch's suggestions, there are lot of materials, thus I will avoid posting links, there's a lot of choice.
Another thing that comes to mind, is to restrict the sensitive files for root users only, and look and "man script" for tracking commands.
