Linux.com provides this tutorial on "afick", a filesystem integrity utility.
With new threats showing up every day, administrators find it increasingly hard to establish continued trust with their filesystems. Luckily, it's easier than you might think to maintain omniscient control of your filesystem. Through effective use of a filesystem integrity checker, you can keep a watchful eye on every aspect of an important machine's filesystem.
There are several filesystem integrity checker applications, both commercial and open source. I chose to deploy afick, because it is written in Perl, which makes it lightweight and easily portable between different operating systems. Though by nature designed for the command line, afick also has an optional Webmin module and a graphical interface written in perl-Tk.
For this article we will focus on the command-line implementation on a SUSE Enterprise 8.0 server, but what you see here should be applicable to just about any *nix distribution.
