Re: User Auditing



Let me tell you why I want this for the sake of this discussion:

We have servers in our environment by which multiple people (inside and out)
can issue commands as either themselves or as root (under sudo of course).
While I would prefer that everything goes through me for changes, that is
not practical here. I want to be informed on what these people/vendors are
doing to my systems at all times and would rather know than to not know, if
that makes sense. It's not 100% about security either but to give me a sense
of what is happening in the environment that I am supporting.
