I log on to a lot of different servers at work to do some tasks and install new software. However, sometimes I find myself wanting to know what has been done to the computer recently. This usually involves me going through log files and just observing the filesystem for new folders/files (usually in /tmp).
Is there some kind of a master log file which logs all (or nearly all) "activity" on the computer. Even getting a list of most recent command line 'history' from different users would be helpful to see what they did in the last couple hours. I only need to know the big things:
- new software installs
- important files being changed
- new users/groups being made
Am I asking for too much from my system? If this doesn't exist I might just develop a tool to do it. In that case, which files should I be looking at to extract the information I want?
