RE: monitor remote rpm database

["Mulley, Nikhil" <mnikhil corp untd com>]

Hi Ed :),
But how it can be spoofed , as  I see that no user has write permissions on /var/lib/rpm
Hmmmm. I know you are taking about local sudo users who can have anything with the system ...
but what is the necessary change that you would suggest at /etc/sudoers file so that no one except genuine root has write permissions on to these files

If you have root access on the system, one easy way to do it is to
simply run rpm on the remote box and see what's been recently installed.  

To report in machine readable format:
# rpm -qa --queryformat '%{installtime} %{name}\n'

To report in a more human-readable format:
# rpm -qa --last

In both cases, you are explicity trusting the rpm database to tell you
which packages were recently installed.  This is not to be used a
security audit since this information could easily be spoofed.

/var/log/rpmpkgs is created on a daily basis with an rpm listing.  It's
then rotated weekly.  See /etc/cron.daily/rpm and /etc/logrotate.d/rpm.
You could customize these reports if you wanted to.  To simply see
what's changed this week:

# diff /var/log/rpmpkgs /var/log/rpmpkgs.1
