I’ve released cfgtrack v1.0: Get notified of changes on your server
Wednesday, June 3rd, 2015
I needed a simple way of being notified when configuration files had been changed on some servers. Nothing fancy. No configuration management, no intrusion detection, no centralised versioning control repositories. Just a simple email saying what’s been changed. I couldn’t find a tool that did just that, and didn’t require massive amounts of configuration, so I wrote one myself.
I’ve just released version 1.0 of the tool, which is available in source, Debian, Redhat and zip packages.
Here’s how simple it is:
$ sudo cfgtrack track /etc/ Now tracking /etc/ # Make some changes in a file $ sudo cfgtrack -a -m email@example.com compare
And I’ll get an email in my mailbox if anything’s been changed since the last time I ran compare. A diff is included to easily spot what has changed.
Add the above to a daily cronjob and you’ll be kept up-to-date about changes to your configuration files. Now you’ll have a heads-up if automatic package upgrades modify configuration files or a co-administrator decided to make some changes.
