This means that the first step toward automating a procedure usually involves manual changes! A development system (such as an SA’s desktop UNIX/Linux system or a dedicated server system) is used to build, install, and configure software. You might need to perform these activities separately for all your site’s operating systems and hardware platforms (SPARC vs. x86 vs. ). Here’s an overview of the automated change development process: s -AKE THE CHANGE IN A TEST ENVIRONMENT s -AKE IT FIT YOUR POLICY FOR EXAMPLE MAKE IT RUN AS A NONROOT USER OR INSTALL IT IN a specific directory tree.
Who has been accessing each system and what have they been doing? Most systems provide process accounting—a log of every executed process, the user who executed it, and the amount of time it was running. You usually have to enable this logging because it can consume quite a bit of drive space. The problem is that when you see that nkkp executed the command ni)nb+dkia+&, how do you know who did it? You know that the nkkp user ran it, but who was logged in as nkkp at that time? Did you make an unfortunate typo, or did the pissed-off employee who quit yesterday do it on purpose?
