Need some help in coming up to log all the activity that is used with our common "unix account".
Ideally I am looking for to log the activity in a "separate" file for each session or login until the user logout, I would like to capture the date/time and terminal login and record all the commands until the user logout.
Auditing has OS-specific components - what UNIX? What shell do you use?
wtmpx is a database ( a file really) that tracks when and from where a user account logs in, when the process logs out. Also check out the script command.
In most shells, and, of course, bash, you have the history file that collects the commands a user puts in. It may become difficult to separate the files if different remote users login to the same account; you may need to apply some tricks to create and keep separate history files.
