Written in Perl, and easy to deploy and use, afick is a filesystem integrity checker with which you can keep a watchful eye on every aspect of an important machine's filesystem.
Designed to be quick and portable, afick runs on a variety of operating systems, including Windows XP/2000, Linux RedHat (7.1, 7.3), Linux Fedora core 1, Linux mandrake (8.2, 9.1, 9.2), Linux Slackware (9.1), HP Tru64 Unix 5.1B and AIX 5.2.0. However, the software should work on just about any machine with Perl installed.
Installation was easy, just a quick download, then extraction, run "perl Makefile.pl" then "make install" and you will be on your way.
Afick is a work in progress. In recent conversations, developer Eric Gerbier said he intends to include in future releases a daemon-enabled version that doesn't rely on cron to run afick, thus delivering real-time filesystem monitoring. An option to export afick's results in HTML/XML is in the works for version 3.0, due out sometime in the next few months.
