You may be interested in a tool I wrote some time ago that makes a
hardware and software snapshot of a system, including the latent
configuration in memory (like routing information or firewall rules).
It creates the snapshots in single compressed text files periodically
(hourly, daily, weekly, monthly from cron) that can be diffed. And it
allows to send out diffs to one or more email-addresses if configured to
It was written with multiple use cases in mind:
- compare identical systems (eg. nodes in a cluster, or when migrating
- mail changes to a group of co-maintaining sysadmins (so configuration
changes are communicated and if needed acted upon)
- backing up a complete system's HW/SW configuration and making diffs
with past configurations for troubleshooting problems
- taking system configurations with you (as a consultant or support
organisation it is nice to follow-up on system changes made
by the customer)
The tool is called dconf. You can find it in RPMforge.
The tool is as good as its configuration. The default configuration
already contains a lot for RHEL/CentOS, but it could use more people
defining more tools/configuration file. And I am open for improving the
tool beyond what it does now.
